Description

Deprecated: This module is a perpetual draft and will therefore be removed from xmonad-contrib in the near future.

This is a draft of a brand new config syntax for xmonad. It aims to be:

- easier to copy/paste snippets from the docs
- easier to get the gist for what's going on, for you imperative programmers

It's brand new, so it's pretty much guaranteed to break or change syntax. But what's the worst that could happen? Xmonad crashes and logs you out? It probably won't do that. Give it a try.

# Start here

To start with, create a `xmonad.hs` that looks like this:

    {-# LANGUAGE RebindableSyntax #-}
    import XMonad.Config.Prime

    -- Imports go here.

    main = xmonad $ do
      nothing
      -- Configs go here.

This will give you a default xmonad install, with room to grow. The lines starting with double dashes are comments. You may delete them. Note that Haskell is a bit precise about indentation. Make sure all the statements in your do-block start at the same column, and make sure that any multi-line statements are formatted with a hanging indent. (For an example, see the 'keys =+' statement in the Example config section, below.)

After changing your config file, restart xmonad with mod-q (where, by default, "mod" == "alt").

xmonad :: forall a (l :: Type -> Type). (Default a, Read (l Window), LayoutClass l Window) => (a -> IO (XConfig l)) -> IO () #

This is the xmonad main function. It passes `def` (the default `XConfig`) into your do-block, takes the modified config out of your do-block, and then runs xmonad.

The do-block is a `Prime`. Advanced readers can skip right to that definition.

nothing :: forall (l :: Type -> Type). Prime l l #

This doesn't modify the config in any way. It's just here for your initial config because Haskell doesn't allow empty do-blocks. Feel free to delete it once you've added other stuff.

# Attributes you can set

These are a bunch of attributes that you can set. Syntax looks like this:

      terminal =: "urxvt"

Strings are double quoted, Dimensions are unquoted integers, booleans are `True` or `False` (case-sensitive), and `modMask` is usually `mod1Mask` or `mod4Mask`.

normalBorderColor :: forall (l :: Type -> Type). Settable String (XConfig l) #

Non-focused windows border color. Default: `"#dddddd"`

focusedBorderColor :: forall (l :: Type -> Type). Settable String (XConfig l) #

Focused windows border color. Default: `"#ff0000"`

terminal :: forall (l :: Type -> Type). Settable String (XConfig l) #

The preferred terminal application. Default: `"xterm"`

modMask :: forall (l :: Type -> Type). Settable KeyMask (XConfig l) #

The mod modifier, as used by key bindings. Default: `mod1Mask` (which is probably alt on your computer).

borderWidth :: forall (l :: Type -> Type). Settable Dimension (XConfig l) #

The border width (in pixels). Default: `1`

focusFollowsMouse :: forall (l :: Type -> Type). Settable Bool (XConfig l) #

Whether window focus follows the mouse cursor on move, or requires a mouse click. (Mouse? What's that?) Default: `True`

clickJustFocuses :: forall (l :: Type -> Type). Settable Bool (XConfig l) #

If True, a mouse click on an inactive window focuses it, but the click is not passed to the window. If False, the click is also passed to the window. Default `True`

class SettableClass (s :: Type -> Type) x y | s -> x y where #

Methods

(=:) :: s c -> y -> Arr c c #

This lets you modify an attribute.

#### Instances

Instances details

UpdateableClass s x y => SettableClass s x y # |
Instance details Defined in XMonad.Config.Prime Methods (=:) :: s c -> y -> Arr c c #

class UpdateableClass (s :: Type -> Type) x y | s -> x y where #

Methods

(=.) :: s c -> (x -> y) -> Arr c c #

This lets you apply a function to an attribute (i.e. read, modify, write).

# Attributes you can add to

In addition to being able to set these attributes, they have a special syntax for being able to add to them. The operator is `=+` (the plus comes after the equals), but each attribute has a different syntax for what comes after the operator.

manageHook :: forall (l :: Type -> Type). Summable ManageHook ManageHook (XConfig l) #

The action to run when a new window is opened. Default:

      manageHook =: composeAll [className =? "MPlayer" --> doFloat, className =? "Gimp" --> doFloat]

To add more rules to this list, you can say, for instance:

    import XMonad.StackSet
    ...
      manageHook =+ (className =? "Emacs" --> doF kill)
      manageHook =+ (className =? "Vim" --> doF shiftMaster)

Note that operator precedence mandates the parentheses here.

handleEventHook :: forall (l :: Type -> Type). Summable (Event -> X All) (Event -> X All) (XConfig l) #

Custom X event handler. Return `All True` if the default handler should also be run afterwards. Default does nothing. To add an event handler:

    import XMonad.Hooks.ServerMode
    ...
      handleEventHook =+ serverModeEventHook

workspaces :: forall (l :: Type -> Type). Summable [String] [String] (XConfig l) #

List of workspaces' names. Default: `map show [1 .. 9 :: Int]`. Adding appends to the end:

      workspaces =+ ["0"]

This is useless unless you also create keybindings for this.

logHook :: forall (l :: Type -> Type). Summable (X ()) (X ()) (XConfig l) #

The action to perform when the windows set is changed. This happens whenever focus change, a window is moved, etc. `logHook =+` takes an `X ()` and appends it via `(>>)`. For instance:

    import XMonad.Hooks.ICCCMFocus
    ...
      logHook =+ takeTopFocus

Note that if your expression is parametrically typed (e.g. of type `MonadIO m => m ()`), you'll need to explicitly annotate it, like so:

      logHook =+ (io $ putStrLn "Hello, world!" :: X ())

startupHook :: forall (l :: Type -> Type). Summable (X ()) (X ()) (XConfig l) #

The action to perform on startup. `startupHook =+` takes an `X ()` and appends it via `(>>)`. For instance:

    import XMonad.Hooks.SetWMName
    ...
      startupHook =+ setWMName "LG3D"

Note that if your expression is parametrically typed (e.g. of type `MonadIO m => m ()`), you'll need to explicitly annotate it, as documented in `logHook`.

clientMask :: forall (l :: Type -> Type). Summable EventMask EventMask (XConfig l) #

The client events that xmonad is interested in. This is useful in combination with handleEventHook. Default: `structureNotifyMask .|. enterWindowMask .|. propertyChangeMask`

      clientMask =+ keyPressMask .|. keyReleaseMask

rootMask :: forall (l :: Type -> Type). Summable EventMask EventMask (XConfig l) #

The root events that xmonad is interested in. This is useful in combination with handleEventHook. Default: `substructureRedirectMask .|. substructureNotifyMask .|. enterWindowMask .|. leaveWindowMask .|. structureNotifyMask .|. buttonPressMask`

class SummableClass (s :: Type -> Type) y | s -> y where #

Methods

(=+) :: s c -> y -> Arr c c infix 0 #

This lets you add to an attribute.

# Attributes you can add to or remove from

The following support the the `=+` for adding items and the `=-` operator for removing items.

keys :: forall (l :: Type -> Type). Keys (XConfig l) #

Key bindings to `X` actions. Default: see ``man xmonad``. `keys` takes a list of keybindings specified emacs-style, as documented in `mkKeyMap`. For example, to change the "kill window" key:

      keys =- ["M-S-c"]
      keys =+ [("M-M1-x", kill)]

mouseBindings :: forall (l :: Type -> Type). MouseBindings (XConfig l) #

Mouse button bindings to an `X` actions on a window. Default: see ``man xmonad``. To make `mod-<scrollwheel>` switch workspaces:

    import XMonad.Actions.CycleWS (nextWS, prevWS)
    ...
      mouseBindings =+ [((mod4Mask, button4), const prevWS),
                        ((mod4Mask, button5), const nextWS)]

Note that you need to specify the numbered mod-mask e.g. `mod4Mask` instead of just `modMask`.

class RemovableClass (r :: Type -> Type) y | r -> y where #

Methods

(=-) :: r c -> y -> Arr c c infix 0 #

This lets you remove from an attribute.

# Modifying the list of workspaces

Workspaces can be configured through `workspaces`, but then the `keys` need to be set, and this can be a bit laborious. `withWorkspaces` provides a convenient mechanism for common workspace updates.

withWorkspaces :: forall (l :: Type -> Type). Arr WorkspaceConfig WorkspaceConfig -> Prime l l #

Configure workspaces through a Prime-like interface. Example:

      withWorkspaces $ do
        wsKeys =+ ["0"]
        wsActions =+ [("M-M1-", windows . swapWithCurrent)]
        wsSetName 1 "mail"

This will set `workspaces` and add the necessary keybindings to `keys`. Note that it won't remove old keybindings; it's just not that clever.

wsNames :: Settable [String] WorkspaceConfig #

The list of workspace names, like `workspaces` but with two differences:

1. If any entry is the empty string, it'll be replaced with the corresponding entry in `wsKeys`.
2. The list is truncated to the size of `wsKeys`.

The default value is ``repeat` ""`.

If you'd like to create workspaces without associated keyspecs, you can do that afterwards, outside the `withWorkspaces` block, with ``workspaces` =+`.

wsKeys :: Summable [String] [String] WorkspaceConfig #

The list of workspace keys. These are combined with the modifiers in `wsActions` to form the keybindings for navigating to workspaces. Default: `["1","2",...,"9"]`.

wsActions :: Summable [(String, String -> X ())] [(String, String -> X ())] WorkspaceConfig #

Mapping from key prefix to command. Its type is `[(String, String -> X())]`. The key prefix may be a modifier such as `"M-"`, or a submap prefix such as `"M-a "`, or both, as in `"M-a M-"`. The command is a function that takes a workspace name and returns an `X ()`. `withWorkspaces` creates keybindings for the cartesian product of `wsKeys` and `wsActions`.

Default:

    [("M-", windows . W.greedyView),
     ("M-S-", windows . W.shift)]

wsSetName :: Int -> String -> Arr WorkspaceConfig WorkspaceConfig #

A convenience for just modifying one entry in `wsNames`, in case you only want a few named workspaces. Example:

        wsSetName 1 "mail"
        wsSetName 2 "web"

# Modifying the screen keybindings

`withScreens` provides a convenient mechanism to set keybindings for moving between screens, much like `withWorkspaces`.

withScreens :: forall (l :: Type -> Type). Arr ScreenConfig ScreenConfig -> Prime l l #

Configure screen keys through a Prime-like interface:

      withScreens $ do
        sKeys =: ["e", "r"]

This will add the necessary keybindings to `keys`. Note that it won't remove old keybindings; it's just not that clever.

sKeys :: Summable [String] [String] ScreenConfig #

The list of screen keys. These are combined with the modifiers in `sActions` to form the keybindings for navigating to workspaces. Default: `["w","e","r"]`.

sActions :: Summable [(String, ScreenId -> X ())] [(String, ScreenId -> X ())] ScreenConfig #

Mapping from key prefix to command. Its type is `[(String, ScreenId -> X())]`. Works the same as `wsActions` except for a different function type.

Default:

    [("M-", windows . onScreens W.view),
     ("M-S-", windows . onScreens W.shift)]

onScreens :: Eq s => (i -> StackSet i l a s sd -> StackSet i l a s sd) -> s -> StackSet i l a s sd -> StackSet i l a s sd #

Converts a stackset transformer parameterized on the workspace type into one parameterized on the screen type. For example, you can use `onScreens W.view 0` to navigate to the workspace on the 0th screen. If the screen id is not recognized, the returned transformer acts as an identity function.

# Modifying the layoutHook

Layouts are special. You can't modify them using the `=:` or `=.` operator. You need to use the following functions.

addLayout :: forall (l :: Type -> Type) r. (LayoutClass l Window, LayoutClass r Window) => r Window -> Prime l (Choose l r) #

Add a layout to the list of layouts choosable with mod-space. For instance:

    import XMonad.Layout.Tabbed
    ...
      addLayout simpleTabbed

resetLayout :: forall r (l :: Type -> Type). LayoutClass r Window => r Window -> Prime l r #

Reset the layoutHook from scratch. For instance, to get rid of the wide layout:

      resetLayout $ Tall 1 (3/100) (1/2) ||| Full

(The dollar is like an auto-closing parenthesis, so all the stuff to the right of it is treated like an argument to resetLayout.)

modifyLayout :: LayoutClass r Window => (l Window -> r Window) -> Prime l r #

Modify your `layoutHook` with some wrapper function. You probably want to call this after you're done calling `addLayout`. Example:

    import XMonad.Layout.NoBorders
    ...
      modifyLayout smartBorders

# Updating the XConfig en masse

Finally, there are a few contrib modules that bundle multiple attribute updates together. There are three types: 1) wholesale replacements for the default config, 2) pure functions on the config, and 3) IO actions on the config. The syntax for each is different. Examples:

1) To start with a `gnomeConfig` instead of the default, we use `startWith`:

    import XMonad.Config.Gnome
    ...
      startWith gnomeConfig

2) `withUrgencyHook` is a pure function, so we need to use `apply`:

    import XMonad.Hooks.UrgencyHook
    ...
      apply $ withUrgencyHook dzenUrgencyHook

3) `xmobar` returns an `IO (XConfig l)`, so we need to use `applyIO`:

    import XMonad.Hooks.DynamicLog
    ...
      applyIO xmobar

startWith :: forall (l' :: Type -> Type) (l :: Type -> Type). XConfig l' -> Prime l l' #

Replace the current `XConfig` with the given one. If you use this, you probably want it to be the first line of your config.

apply :: forall (l :: Type -> Type) (l' :: Type -> Type). (XConfig l -> XConfig l') -> Prime l l' #

Turns a pure function on `XConfig` into a `Prime`.

applyIO :: forall (l :: Type -> Type) (l' :: Type -> Type). (XConfig l -> IO (XConfig l')) -> Prime l l' #

Turns an IO function on `XConfig` into a `Prime`.

# The rest of the world

Everything you know and love from the core XMonad module is available for use in your config file, too.

These atoms describe window manager protocols in which the owner of this window is willing to participate. If the property exists, is of type ATOM, is of format 32, and the atom WM_PROTOCOLS can be interned, XGetWMProtocols sets the protocols_return argument to a list of atoms, sets the count_return argument to the number of elements in the list, and returns a nonzero status. Otherwise, it sets neither of the return arguments and returns a zero status. To release the list of atoms, use XFree.

class Monad m => MonadIO (m :: Type -> Type) where #

Monads in which `IO` computations may be embedded. Any monad built by applying a sequence of monad transformers to the `IO` monad will be an instance of this class.

Instances should satisfy the following laws, which state that `liftIO` is a transformer of monads:

-     liftIO . return = return

-     liftIO (m >>= f) = liftIO m >>= (liftIO . f)

Methods

liftIO :: IO a -> m a #

Lift a computation from the `IO` monad. This allows us to run IO computations in any monadic stack, so long as it supports these kinds of operations (i.e. `IO` is the base monad for the stack).

### Example

Expand

    import Control.Monad.Trans.State -- from the "transformers" library

    printState :: Show s => StateT s IO ()
    printState = do
      state <- get
      liftIO $ print state

Had we omitted ``liftIO``, we would have ended up with this error:

    • Couldn't match type ‘IO’ with ‘StateT s IO’
     Expected type: StateT s IO ()
       Actual type: IO ()

The important part here is the mismatch between `StateT s IO ()` and ``IO` ()`.

Luckily, we know of a function that takes an ``IO` a` and returns an `(m a)`: ``liftIO``, enabling us to run the program and see the expected results:

    > evalStateT printState "hello"
    "hello"

    > evalStateT printState 3
    3

Maps an old state to a new state inside a state monad. The old state is thrown away.

         Main> :t modify ((+1) :: Int -> Int)
         modify (...) :: (MonadState Int a) => a ()

This says that `modify (+1)` acts over any Monad that is a member of the `MonadState` class, with an `Int` state.

gets :: MonadState s m => (s -> a) -> m a #

Gets specific component of the state, using a projection function supplied.

float :: Window -> X () #

Make a tiled window floating, using its suggested rectangle

restart :: String -> Bool -> X () #

`restart name resume` attempts to restart xmonad by executing the program `name`. If `resume` is `True`, restart with the current window state. When executing another window manager, `resume` should be `False`.

focus :: Window -> X () #

Set focus explicitly to window `w` if it is managed by us, or root. This happens if X notices we've moved the mouse (and perhaps moved the mouse to a new screen).

type Directories = Directories' FilePath #

Convenient type alias for the most common case in which one might want to use the `Directories` type.

data Directories' a #

All the directories that xmonad will use. They will be used for the following purposes:

- `dataDir`: This directory is used by XMonad to store data files such as the run-time state file.
- `cfgDir`: This directory is where user configuration files are stored (e.g, the xmonad.hs file). You may also create a `lib` subdirectory in the configuration directory and the default recompile command will add it to the GHC include path.
- `cacheDir`: This directory is used to store temporary files that can easily be recreated such as the configuration binary and any intermediate object files generated by GHC. Also, the XPrompt history file goes here.

For how these directories are chosen, see `getDirectories`.

initialValue

Methods

initialValue :: a #

Defines an initial value for the state extension

extensionType :: a -> StateExtension #

Specifies whether the state extension should be persistent. Setting this method to `PersistentExtension` will make the stored data survive restarts, but requires a to be an instance of Read and Show.

It defaults to `StateExtension`, i.e. no persistence.

class (Show (layout a), Typeable layout) => LayoutClass (layout :: Type -> Type) a where #

Every layout must be an instance of `LayoutClass`, which defines the basic layout operations along with a sensible default for each.

All of the methods have default implementations, so there is no minimal complete definition. They do, however, have a dependency structure by default; this is something to be aware of should you choose to implement one of these methods. Here is how a minimal complete definition would look like if we did not provide any default implementations:

- `runLayout` || ((`doLayout` || `pureLayout`) && `emptyLayout`)
- `handleMessage` || `pureMessage`
- `description`

Note that any code which uses `LayoutClass` methods should only ever call `runLayout`, `handleMessage`, and `description`! In other words, the only calls to `doLayout`, `pureMessage`, and other such methods should be from the default implementations of `runLayout`, `handleMessage`, and so on. This ensures that the proper methods will be used, regardless of the particular methods that any `LayoutClass` instance chooses to define.

Nothing

Methods

runLayout :: Workspace WorkspaceId (layout a) a -> Rectangle -> X ([(a, Rectangle)], Maybe (layout a)) #

By default, `runLayout` calls `doLayout` if there are any windows to be laid out, and `emptyLayout` otherwise. Most instances of `LayoutClass` probably do not need to implement `runLayout`; it is only useful for layouts which wish to make use of more of the `Workspace` information (for example, XMonad.Layout.PerWorkspace).

doLayout :: layout a -> Rectangle -> Stack a -> X ([(a, Rectangle)], Maybe (layout a)) #

Given a `Rectangle` in which to place the windows, and a `Stack` of windows, return a list of windows and their corresponding Rectangles. If an element is not given a Rectangle by `doLayout`, then it is not shown on screen. The order of windows in this list should be the desired stacking order.

Also possibly return a modified layout (by returning `Just newLayout`), if this layout needs to be modified (e.g. if it keeps track of some sort of state). Return `Nothing` if the layout does not need to be modified.

Layouts which do not need access to the `X` monad (`IO`, window manager state, or configuration) and do not keep track of their own state should implement `pureLayout` instead of `doLayout`.

pureLayout :: layout a -> Rectangle -> Stack a -> [(a, Rectangle)] #

This is a pure version of `doLayout`, for cases where we don't need access to the `X` monad to determine how to lay out the windows, and we don't need to modify the layout itself.

emptyLayout :: layout a -> Rectangle -> X ([(a, Rectangle)], Maybe (layout a)) #

`emptyLayout` is called when there are no windows.

handleMessage :: layout a -> SomeMessage -> X (Maybe (layout a)) #

`handleMessage` performs message handling. If `handleMessage` returns `Nothing`, then the layout did not respond to the message and the screen is not refreshed. Otherwise, `handleMessage` returns an updated layout and the screen is refreshed.

Layouts which do not need access to the `X` monad to decide how to handle messages should implement `pureMessage` instead of `handleMessage` (this restricts the risk of error, and makes testing much easier).

pureMessage :: layout a -> SomeMessage -> Maybe (layout a) #

Respond to a message by (possibly) changing our layout, but taking no other action. If the layout changes, the screen will be refreshed.

description :: layout a -> String #

This should be a human-readable string that is used when selecting layouts by name. The default implementation is `show`, which is in some cases a poor default.

readsLayout :: Layout a -> String -> [(Layout a, String)] #

Using the `Layout` as a witness, parse existentially wrapped windows from a `String`.

fromMessage :: Message m => SomeMessage -> Maybe m #

And now, unwrap a given, unknown `Message` type, performing a (dynamic) type check on the result.

ifM :: Monad m => m Bool -> m a -> m a -> m a #

If-then-else lifted to a `Monad`.

io :: MonadIO m => IO a -> m a #

Lift an `IO` action into the `X` monad

catchIO :: MonadIO m => IO () -> m () #

Lift an `IO` action into the `X` monad. If the action results in an `IO` exception, log the exception to stderr and continue normal execution.

spawn :: MonadIO m => String -> m () #

spawn. Launch an external application. Specifically, it double-forks and runs the `String` you pass as a command to /bin/sh.

Note this function assumes your locale uses utf8.

spawnPID :: MonadIO m => String -> m ProcessID #

Like `spawn`, but returns the `ProcessID` of the launched application

xfork :: MonadIO m => IO () -> m ProcessID #

A replacement for `forkProcess` which resets default signal handlers.

xmessage :: MonadIO m => String -> m () #

Use `xmessage` to show information to the user.

runOnWorkspaces :: (WindowSpace -> X WindowSpace) -> X () #

This is basically a map function, running a function in the `X` monad on each workspace with the output of that function being the modified workspace.

getDirectories :: IO Directories #

Build up the `Dirs` that xmonad will use. They are chosen as follows:

1. If all three of xmonad's environment variables (`XMONAD_DATA_DIR`, `XMONAD_CONFIG_DIR`, and `XMONAD_CACHE_DIR`) are set, use them.
2. If there is a build script called `build` or configuration `xmonad.hs` in `~/.xmonad`, set all three directories to `~/.xmonad`.
3. Otherwise, use the `xmonad` directory in `XDG_DATA_HOME`, `XDG_CONFIG_HOME`, and `XDG_CACHE_HOME` (or their respective fallbacks). These directories are created if necessary.

The xmonad configuration file (or the build script, if present) is always assumed to be in `cfgDir`.

getXMonadDir :: X String #

Return the path to the xmonad configuration directory.

getXMonadCacheDir :: X String #

Return the path to the xmonad cache directory.

getXMonadDataDir :: X String #

Return the path to the xmonad data directory.

binFileName :: Directories -> FilePath #

stateFileName :: Directories -> FilePath #

recompile :: MonadIO m => Directories -> Bool -> m Bool #

Recompile the xmonad configuration file when any of the following apply:

- force is `True`
- the xmonad executable does not exist
- the xmonad executable is older than `xmonad.hs` or any file in the `lib` directory (under the configuration directory)
- custom `build` script is being used

The -i flag is used to restrict recompilation to the xmonad.hs file only, and any files in the aforementioned `lib` directory.

Compilation errors (if any) are logged to the `xmonad.errors` file in the xmonad data directory. If GHC indicates failure with a non-zero exit code, an xmessage displaying that file is spawned.

`False` is returned if there are compilation errors.

whenJust :: Monad m => Maybe a -> (a -> m ()) -> m () #

Conditionally run an action, using a `Maybe a` to decide.

whenX :: X Bool -> X () -> X () #

Conditionally run an action, using a `X` event to decide

uninstallSignalHandlers :: MonadIO m => m () #

newtype JumpToLayout #

A message to jump to a particular layout, specified by its description string.

The argument given to a `JumpToLayout` message should be the `description` of the layout to be selected. If you use XMonad.Hooks.DynamicLog from `xmonad-contrib`, this is the name of the layout displayed in your status bar. Alternatively, you can use GHCi to determine the proper name to use. For example:

    $ ghci
    GHCi, version 6.8.2: http://www.haskell.org/ghc/  :? for help
    Loading package base ... linking ... done.
    :set prompt "> "    -- don't show loaded module names
    > :m +XMonad.Core   -- load the xmonad core
    > :m +XMonad.Layout.Grid  -- load whatever module you want to use
    > description Grid  -- find out what it's called
    "Grid"

As yet another (possibly easier) alternative, you can use the XMonad.Layout.Renamed module (also in `xmonad-contrib`) to give custom names to your layouts, and use those.

For example, if you want to jump directly to the `Full` layout you can do

    , ((modm .|. controlMask, xK_f), sendMessage $ JumpToLayout "Full")

Arguments

:: Rational | `frac`, what proportion of the screen to devote to the master area
-> Rectangle | `r`, the rectangle representing the screen
-> Int | `nmaster`, the number of windows in the master pane
-> Int | `n`, the total number of windows to tile
-> [Rectangle] |

Compute the positions for windows using the default two-pane tiling algorithm.

The screen is divided into two panes. All clients are then partitioned between these two panes. One pane, the master, by convention has the least number of windows in it.

isFixedSizeOrTransient :: Display -> Window -> X Bool #

Detect whether a window has fixed size or is transient. This check can be used to determine whether the window should be floating or not

manage :: Window -> X () #

Add a new window to be managed in the current workspace. Bring it into focus.

Whether the window is already managed, or not, it is mapped, has its border set, and its event mask set.

unmanage :: Window -> X () #

A window no longer exists; remove it from the window list, on whatever workspace it is.

killWindow :: Window -> X () #

Kill the specified window. If we do kill it, we'll get a delete notify back from X.

There are two ways to delete a window. Either just kill it, or if it supports the delete protocol, send a delete event (e.g. firefox)

kill :: X () #

Kill the currently focused client.

windows :: (WindowSet -> WindowSet) -> X () #

Modify the current window list with a pure function, and refresh

modifyWindowSet :: (WindowSet -> WindowSet) -> X () #

Modify the `WindowSet` in state with no special handling.

windowBracket :: (a -> Bool) -> X a -> X a #

Perform an `X` action and check its return value against a predicate p. If p holds, unwind changes to the `WindowSet` and replay them using `windows`.

windowBracket_ :: X Any -> X () #

Perform an `X` action. If it returns `Any True`, unwind the changes to the `WindowSet` and replay them using `windows`. This is a version of `windowBracket` that discards the return value and handles an `X` action that reports its need for refresh via `Any`.

scaleRationalRect :: Rectangle -> RationalRect -> Rectangle #

Produce the actual rectangle from a screen and a ratio on that screen.

setWMState :: Window -> Int -> X () #

Set a window's WM_STATE property.

setWindowBorderWithFallback :: Display -> Window -> String -> Pixel -> X () #

Set the border color using the window's color map, if possible; otherwise fall back to the color in `Pixel`.

hide :: Window -> X () #

Hide a window by unmapping it and setting Iconified.

reveal :: Window -> X () #

Show a window by mapping it and setting Normal. This is harmless if the window was already visible.

setInitialProperties :: Window -> X () #

Set some properties when we initially gain control of a window.

refresh :: X () #

Render the currently visible workspaces, as determined by the `StackSet`. Also, set focus to the focused window.

This is our `view` operation (MVC), in that it pretty prints our model with X calls.

clearEvents :: EventMask -> X () #

Remove all events of a given type from the event queue.

tileWindow :: Window -> Rectangle -> X () #

Move and resize `w` such that it fits inside the given rectangle, including its border.

containedIn :: Rectangle -> Rectangle -> Bool #

Returns `True` if the first rectangle is contained within, but not equal to the second.

nubScreens :: [Rectangle] -> [Rectangle] #

Given a list of screens, remove all duplicated screens and screens that are entirely contained within another.

getCleanedScreenInfo :: MonadIO m => Display -> m [Rectangle] #

Clean the list of screens according to the rules documented for nubScreens.

rescreen :: X () #

The screen configuration may have changed (due to -- xrandr), update the state and refresh the screen, and reset the gap.

setButtonGrab :: Bool -> Window -> X () #

Tell whether or not to intercept clicks on a given window

setTopFocus :: X () #

Set the focus to the window on top of the stack, or root

setFocusX :: Window -> X () #

Call X to set the keyboard focus details.

cacheNumlockMask :: X () #

mkGrabs :: [(KeyMask, KeySym)] -> X [(KeyMask, KeyCode)] #

Given a list of keybindings, turn the given `KeySym`s into actual `KeyCode`s and prepare them for grabbing.

unGrab :: X () #

Release XMonad's keyboard grab, so other grabbers can do their thing.

Start a keyboard action with this if it is going to run something that needs to do a keyboard, pointer, or server grab. For example,

    , ((modm .|. controlMask, xK_p), unGrab >> spawn "scrot")

(Other examples are certain screen lockers and "gksu".) This avoids needing to insert a pause/sleep before running the command.

XMonad retains the keyboard grab during key actions because if they use a submap, they need the keyboard to be grabbed, and if they had to assert their own grab then the asynchronous nature of X11 allows race conditions between XMonad, other clients, and the X server that would cause keys to sometimes be "leaked" to the focused window.

sendMessage :: Message a => a -> X () #

Throw a message to the current `LayoutClass` possibly modifying how we layout the windows, in which case changes are handled through a refresh.

broadcastMessage :: Message a => a -> X () #

Send a message to all layouts, without refreshing.

sendMessageWithNoRefresh :: Message a => a -> WindowSpace -> X () #

Send a message to a layout, without refreshing.

updateLayout :: WorkspaceId -> Maybe (Layout Window) -> X () #

Update the layout field of a workspace.

setLayout :: Layout Window -> X () #

isClient :: Window -> X Bool #

Is the window is under management by xmonad?

extraModifiers :: X [KeyMask] #

Combinations of extra modifier masks we need to grab keys/buttons for. (numlock and capslock)

cleanMask :: KeyMask -> X KeyMask #

Strip numlock/capslock from a mask.

initColor :: Display -> String -> IO (Maybe Pixel) #

Get the `Pixel` value for a named color.

writeStateToFile :: X () #

Write the current window state (and extensible state) to a file so that xmonad can resume with that state intact.

readStateFile :: forall (l :: Type -> Type). (LayoutClass l Window, Read (l Window)) => XConfig l -> X (Maybe XState) #

Read the state of a previous xmonad instance from a file and return that state. The state file is removed after reading it.

floatLocation :: Window -> X (ScreenId, RationalRect) #

Given a window, find the screen it is located on, and compute the geometry of that window WRT that screen.

pointScreen :: Position -> Position -> X (Maybe (Screen WorkspaceId (Layout Window) Window ScreenId ScreenDetail)) #

Given a point, determine the screen (if any) that contains it.

pointWithin :: Position -> Position -> Rectangle -> Bool #

`pointWithin x y r` returns `True` if the `(x, y)` co-ordinate is within `r`.

mouseDrag :: (Position -> Position -> X ()) -> X () -> X () #

Accumulate mouse motion events

mouseMoveWindow :: Window -> X () #

Drag the window under the cursor with the mouse while it is dragged.

mouseResizeWindow :: Window -> X () #

Resize the window under the cursor with the mouse while it is dragged.

mkAdjust :: Window -> X (D -> D) #

Given a window, build an adjuster function that will reduce the given dimensions according to the window's border width and size hints.

applySizeHints :: Integral a => Dimension -> SizeHints -> (a, a) -> D #

Reduce the dimensions if needed to comply to the given SizeHints, taking window borders into account.

applySizeHintsContents :: Integral a => SizeHints -> (a, a) -> D #

Reduce the dimensions if needed to comply to the given SizeHints.

applySizeHints' :: SizeHints -> D -> D #

Use X11 size hints to scale a pair of dimensions.

applyAspectHint :: (D, D) -> D -> D #

Reduce the dimensions so their aspect ratio falls between the two given aspect ratios.

applyResizeIncHint :: D -> D -> D #

Reduce the dimensions so they are a multiple of the size increments.

applyMaxSizeHint :: D -> D -> D #

buildLaunch :: Directories -> IO () #

Build the xmonad configuration file with ghc, then execute it. If there are no errors, this function does not return. An exception is raised in any of these cases:

- ghc missing
- both the configuration file and executable are missing
- xmonad.hs fails to compile
- * wrong ghc in path (fails to compile)
- * type error, syntax error, ..
- Missing XMonad/XMonadContrib modules due to ghc upgrade

launch :: forall (l :: Type -> Type). (LayoutClass l Window, Read (l Window)) => XConfig l -> Directories -> IO () #

Entry point into xmonad for custom builds.

This function isn't meant to be called by the typical xmonad user because it:

- Does not process any command line arguments.
- Therefore doesn't know how to restart a running xmonad.
- Does not compile your configuration file since it assumes it's actually running from within your compiled configuration.

Unless you know what you are doing, you should probably be using the `xmonad` function instead.

However, if you are using a custom build environment (such as stack, cabal, make, etc.) you will likely want to call this function instead of `xmonad`. You probably also want to have a key binding to the `restart` function that restarts your custom binary with the resume flag set to `True`.

(Almost) everything you know and love from the Haskell Prelude is available for use in your config file. Note that `>>` has been overriden, so if you want to create do-blocks for normal monads, you'll need some let statements or a separate module. (See the Troubleshooting section.)

data Char #

The character type `Char` represents Unicode codespace and its elements are code points as in definitions D9 and D10 of the Unicode Standard.

Character literals in Haskell are single-quoted: `'Q'`, `'Я'` or `'Ω'`. To represent a single quote itself use `'\''`, and to represent a backslash use `'\\'`. The full grammar can be found in the section 2.6 of the Haskell 2010 Language Report.

To specify a character by its code point one can use decimal, hexadecimal or octal notation: `'\65'`, `'\x41'` and `'\o101'` are all alternative forms of `'A'`. The largest code point is `'\x10ffff'`.

There is a special escape syntax for ASCII control characters:

Escape | Alternatives | Meaning
--- | --- | ---
`'\NUL'` | `'\0'` | null character
`'\SOH'` | `'\1'` | start of heading
`'\STX'` | `'\2'` | start of text
`'\ETX'` | `'\3'` | end of text
`'\EOT'` | `'\4'` | end of transmission
`'\ENQ'` | `'\5'` | enquiry
`'\ACK'` | `'\6'` | acknowledge
`'\BEL'` | `'\7'`, `'\a'` | bell (alert)
`'\BS'` | `'\8'`, `'\b'` | backspace
`'\HT'` | `'\9'`, `'\t'` | horizontal tab
`'\LF'` | `'\10'`, `'\n'` | line feed (new line)
`'\VT'` | `'\11'`, `'\v'` | vertical tab
`'\FF'` | `'\12'`, `'\f'` | form feed
`'\CR'` | `'\13'`, `'\r'` | carriage return
`'\SO'` | `'\14'` | shift out
`'\SI'` | `'\15'` | shift in
`'\DLE'` | `'\16'` | data link escape
`'\DC1'` | `'\17'` | device control 1
`'\DC2'` | `'\18'` | device control 2
`'\DC3'` | `'\19'` | device control 3
`'\DC4'` | `'\20'` | device control 4
`'\NAK'` | `'\21'` | negative acknowledge
`'\SYN'` | `'\22'` | synchronous idle
`'\ETB'` | `'\23'` | end of transmission block
`'\CAN'` | `'\24'` | cancel
`'\EM'` | `'\25'` | end of medium
`'\SUB'` | `'\26'` | substitute
`'\ESC'` | `'\27'` | escape
`'\FS'` | `'\28'` | file separator
`'\GS'` | `'\29'` | group separator
`'\RS'` | `'\30'` | record separator

Ord Double | IEEE 754 `Double`-precision type includes not only numbers, but also positive and negative infinities and a special element called `NaN` (which can be quiet or signal). IEEE 754-2008, section 5.11 requires that if at least one of arguments of `<=`, `<`, `>`, `>=` is `NaN` then the result of the comparison is `False`, and `instance` `Ord` `Double` complies with this requirement. This violates the reflexivity: both `NaN` `<=` `NaN` and `NaN` `>=` `NaN` are `False`. IEEE 754-2008, section 5.10 defines `totalOrder` predicate. Unfortunately, `compare` on `Double`s violates the IEEE standard and does not define a total order. More specifically, both `compare` `NaN` `x` and `compare` `x` `NaN` always return `GT`. Thus, users must be extremely cautious when using `instance` `Ord` `Double`. For instance, one should avoid ordered containers with keys represented by `Double`, because data loss and corruption may happen. An IEEE-compliant `compare` is available in `fp-ieee` package as `TotallyOrdered` newtype. Moving further, the behaviour of `min` and `max` with regards to `NaN` is also non-compliant. IEEE 754-2008, section 5.3.1 defines that quiet `NaN` should be treated as a missing data by `minNum` and `maxNum` functions, for example, `minNum(NaN, 1) = minNum(1, NaN) = 1`. Some languages such as Java deviate from the standard implementing `minNum(NaN, 1) = minNum(1, NaN) = NaN`. However, `min` / `max` in `base` are even worse: `min` `NaN` 1 is 1, but `min` 1 `NaN` is `NaN`. IEEE 754-2008 compliant `min` / `max` can be found in `ieee754` package under `minNum` / `maxNum` names. Implementations compliant with `minimumNumber` / `maximumNumber` from a newer IEEE 754-2019, section 9.6 are available from `fp-ieee` package.

data Maybe a #

The `Maybe` type encapsulates an optional value. A value of type ``Maybe` a` either contains a value of type `a` (represented as ``Just` a`), or it is empty (represented as `Nothing`). Using `Maybe` is a good way to deal with errors or exceptional cases without resorting to drastic measures such as `error`.

The `Maybe` type is also a monad. It is a simple kind of error monad, where all errors are represented by `Nothing`. A richer error monad can be built using the `Either` type.

class a ~# b => (a :: k) ~ (b :: k) infix 4 #

Lifted, homogeneous equality. By lifted, we mean that it can be bogus (deferred type error). By homogeneous, the two types `a` and `b` must have the same kinds.

data Integer #

Arbitrary precision integers. In contrast with fixed-size integral types such as `Int`, the `Integer` type represents the entire infinite range of integers.

Integers are stored in a kind of sign-magnitude form, hence do not expect two's complement form when using bit operations.

If the value is small (fit into an `Int`), `IS` constructor is used. Otherwise `IP` and `IN` constructors are used to store a `BigNat` representing respectively the positive or the negative value magnitude.

Invariant: `IP` and `IN` are used iff value doesn't fit in `IS`

data IO a #

A value of type ``IO` a` is a computation which, when performed, does some I/O before returning a value of type `a`.

There is really only one way to "perform" an I/O action: bind it to `Main.main` in your program. When your program is run, the I/O will be performed. It isn't possible to perform I/O from an arbitrary function, unless that function is itself in the `IO` monad and called at some point, directly or indirectly, from `Main.main`.

`IO` is a monad, so `IO` actions can be combined using either the do-notation or the `>>` and `>>=` operations from the `Monad` class.

fromIntegral :: (Integral a, Num b) => a -> b #

General coercion from `Integral` types.

WARNING: This function performs silent truncation if the result type is not at least as big as the argument's type.

realToFrac :: (Real a, Fractional b) => a -> b #

General coercion to `Fractional` types.

WARNING: This function goes through the `Rational` type, which does not have values for `NaN` for example. This means it does not round-trip.

For `Double` it also behaves differently with or without -O0:

    Prelude> realToFrac nan -- With -O0
    -Infinity
    Prelude> realToFrac nan
    NaN

class (Num a, Ord a) => Real a where #

Real numbers.

The Haskell report defines no laws for `Real`, however `Real` instances are customarily expected to adhere to the following law:

Coherence with `fromRational`
  if the type also implements `Fractional`, then `fromRational` is a left inverse for `toRational`, i.e. `fromRational (toRational i) = i`

The law does not hold for `Float`, `Double`, `CFloat`, `CDouble`, etc., because these types contain non-finite values, which cannot be roundtripped through `Rational`.

class (Real a, Enum a) => Integral a where #

Integral numbers, supporting integer division.

The Haskell Report defines no laws for `Integral`. However, `Integral` instances are customarily expected to define a Euclidean domain and have the following properties for the `div`/`mod` and `quot`/`rem` pairs, given suitable Euclidean functions `f` and `g`:

- `x` = `y * quot x y + rem x y` with `rem x y` = `fromInteger 0` or `g (rem x y)` < `g y`
- `x` = `y * div x y + mod x y` with `mod x y` = `fromInteger 0` or `f (mod x y)` < `f y`

An example of a suitable Euclidean function, for `Integer`'s instance, is `abs`.

In addition, `toInteger` should be total, and `fromInteger` should be a left inverse for it, i.e. `fromInteger (toInteger i) = i`.

class Num a => Fractional a where #

Fractional numbers, supporting real division.

The Haskell Report defines no laws for `Fractional`. However, `(`+`)` and `(`*`)` are customarily expected to define a division ring and have the following properties:

`recip` gives the multiplicative inverse
  `x * recip x` = `recip x * x` = `fromInteger 1`
Totality of `toRational`
  `toRational` is total
Coherence with `toRational`
  if the type also implements `Real`, then `fromRational` is a left inverse for `toRational`, i.e. `fromRational (toRational i) = i`

Note that it isn't customarily expected that a type instance of `Fractional` implement a field. However, all instances in `base` do.

Methods

(/) :: a -> a -> a infixl 7 #

Fractional division.

recip :: a -> a #

Reciprocal fraction.

fromRational :: Rational -> a #

Conversion from a `Rational` (that is ``Ratio` `Integer``). A floating literal stands for an application of `fromRational` to a value of type `Rational`, so such literals have type `(`Fractional` a) => a`.

properFraction

Methods

properFraction :: Integral b => a -> (b, a) #

The function `properFraction` takes a real fractional number `x` and returns a pair `(n,f)` such that `x = n+f`, and:

- `n` is an integral number with the same sign as `x`; and
- `f` is a fraction with the same type and sign as `x`, and with absolute value less than `1`.

The default definitions of the `ceiling`, `floor`, `truncate` and `round` functions are in terms of `properFraction`.

truncate :: Integral b => a -> b #

``truncate` x` returns the integer nearest `x` between zero and `x`

round :: Integral b => a -> b #

``round` x` returns the nearest integer to `x`; the even integer if `x` is equidistant between two integers

ceiling :: Integral b => a -> b #

``ceiling` x` returns the least integer not less than `x`

floor :: Integral b => a -> b #

``floor` x` returns the greatest integer not greater than `x`

error :: HasCallStack => [Char] -> a #

`error` stops execution and displays an error message.

data Either a b #

The `Either` type represents values with two possibilities: a value of type ``Either` a b` is either ``Left` a` or ``Right` b`.

The `Either` type is sometimes used to represent a value which is either correct or an error; by convention, the `Left` constructor is used to hold an error value and the `Right` constructor is used to hold a correct value (mnemonic: "right" also means "correct").

#### Examples

Expand

The type ``Either` `String` `Int`` is the type of values which can be either a `String` or an `Int`. The `Left` constructor can be used only on `String`s, and the `Right` constructor can be used only on `Int`s:

    >>> let s = Left "foo" :: Either String Int
    >>> s
    Left "foo"
    >>> let n = Right 3 :: Either String Int
    >>> n
    Right 3
    >>> :type s
    s :: Either String Int
    >>> :type n
    n :: Either String Int

The `fmap` from our `Functor` instance will ignore `Left` values, but will apply the supplied function to values contained in a `Right`:

    >>> let s = Left "foo" :: Either String Int
    >>> let n = Right 3 :: Either String Int
    >>> fmap (*2) s
    Left "foo"
    >>> fmap (*2) n
    Right 6

The `Monad` instance for `Either` allows us to chain together multiple actions which may fail, and fail overall if any of the individual steps failed. First we'll write a function that can either parse an `Int` from a `Char`, or fail.

    >>> import Data.Char ( digitToInt, isDigit )
    >>> :{
        let parseEither :: Char -> Either String Int
            parseEither c
              | isDigit c = Right (digitToInt c)
              | otherwise = Left "parse error"
    >>> :}

The following should work, since both `'1'` and `'2'` can be parsed as `Int`s.

    >>> :{
        let parseMultiple :: Either String Int
            parseMultiple = do
              x <- parseEither '1'
              y <- parseEither '2'
              return (x + y)
    >>> :}

    >>> parseMultiple
    Right 3

But the following should fail overall, since the first operation where we attempt to parse `'m'` as an `Int` will fail:

    >>> :{
        let parseMultiple :: Either String Int
            parseMultiple = do
              x <- parseEither 'm'
              y <- parseEither '2'
              return (x + y)
    >>> :}

    >>> parseMultiple
    Left "parse error"

class Foldable (t :: Type -> Type) where #

The Foldable class represents data structures that can be reduced to a summary value one element at a time. Strict left-associative folds are a good fit for space-efficient reduction, while lazy right-associative folds are a good fit for corecursive iteration, or for folds that short-circuit after processing an initial subsequence of the structure's elements.

Instances can be derived automatically by enabling the `DeriveFoldable` extension. For example, a derived instance for a binary tree might be:

    {-# LANGUAGE DeriveFoldable #-}
    data Tree a = Empty
                | Leaf a
                | Node (Tree a) a (Tree a)
        deriving Foldable

A more detailed description can be found in the Overview section of Data.Foldable.

For the class laws see the Laws section of Data.Foldable.

foldMap | foldr

Methods

foldMap :: Monoid m => (a -> m) -> t a -> m #

Map each element of the structure into a monoid, and combine the results with `(`<>`)`. This fold is right-associative and lazy in the accumulator. For strict left-associative folds consider `foldMap'` instead.

#### Examples

Expand

Basic usage:

    >>> foldMap Sum [1, 3, 5]
    Sum {getSum = 9}

    >>> foldMap Product [1, 3, 5]
    Product {getProduct = 15}

    >>> foldMap (replicate 3) [1, 2, 3]
    [1,1,1,2,2,2,3,3,3]

When a Monoid's `(`<>`)` is lazy in its second argument, `foldMap` can return a result even from an unbounded structure. For example, lazy accumulation enables Data.ByteString.Builder to efficiently serialise large data structures and produce the output incrementally:

    >>> import qualified Data.ByteString.Lazy as L
    >>> import qualified Data.ByteString.Builder as B
    >>> let bld :: Int -> B.Builder; bld i = B.intDec i <> B.word8 0x20
    >>> let lbs = B.toLazyByteString $ foldMap bld [0..]
    >>> L.take 64 lbs
    "0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24"

foldr :: (a -> b -> b) -> b -> t a -> b #

Right-associative fold of a structure, lazy in the accumulator.

In the case of lists, `foldr`, when applied to a binary operator, a starting value (typically the right-identity of the operator), and a list, reduces the list using the binary operator, from right to left:

    foldr f z [x1, x2, ..., xn] == x1 `f` (x2 `f` ... (xn `f` z)...)

Note that since the head of the resulting expression is produced by an application of the operator to the first element of the list, given an operator lazy in its right argument, `foldr` can produce a terminating expression from an unbounded list.

For a general `Foldable` structure this should be semantically identical to,

    foldr f z = foldr f z . toList

#### Examples

Expand

Basic usage:

    >>> foldr (||) False [False, True, False]
    True

    >>> foldr (||) False []
    False

    >>> foldr (\c acc -> acc ++ [c]) "foo" ['a', 'b', 'c', 'd']
    "foodcba"

##### Infinite structures

⚠️ Applying `foldr` to infinite structures usually doesn't terminate.

It may still terminate under one of the following conditions:

- the folding function is short-circuiting
- the folding function is lazy on its second argument

###### Short-circuiting

`(`||`)` short-circuits on `True` values, so the following terminates because there is a `True` value finitely far from the left side:

    >>> foldr (||) False (True : repeat False)
    True

But the following doesn't terminate:

    >>> foldr (||) False (repeat False ++ [True])
    * Hangs forever *

###### Laziness in the second argument

Applying `foldr` to infinite structures terminates when the operator is lazy in its second argument (the initial accumulator is never used in this case, and so could be left `undefined`, but `[]` is more clear):

    >>> take 5 $ foldr (\i acc -> i : fmap (+3) acc) [] (repeat 1)
    [1,4,7,10,13]

foldl :: (b -> a -> b) -> b -> t a -> b #

Left-associative fold of a structure, lazy in the accumulator. This is rarely what you want, but can work well for structures with efficient right-to-left sequencing and an operator that is lazy in its left argument.

In the case of lists, `foldl`, when applied to a binary operator, a starting value (typically the left-identity of the operator), and a list, reduces the list using the binary operator, from left to right:

    foldl f z [x1, x2, ..., xn] == (...((z `f` x1) `f` x2) `f`...) `f` xn

Note that to produce the outermost application of the operator the entire input list must be traversed. Like all left-associative folds, `foldl` will diverge if given an infinite list.

If you want an efficient strict left-fold, you probably want to use `foldl'` instead of `foldl`. The reason for this is that the latter does not force the inner results (e.g. `z `f` x1` in the above example) before applying them to the operator (e.g. to `(`f` x2)`). This results in a thunk chain O(n) elements long, which then must be evaluated from the outside-in.

For a general `Foldable` structure this should be semantically identical to:

    foldl f z = foldl f z . toList

#### Examples

Expand

The first example is a strict fold, which in practice is best performed with `foldl'`.

    >>> foldl (+) 42 [1,2,3,4]
    52

Though the result below is lazy, the input is reversed before prepending it to the initial accumulator, so corecursion begins only after traversing the entire input string.

    >>> foldl (\acc c -> c : acc) "abcd" "efgh"
    "hgfeabcd"

A left fold of a structure that is infinite on the right cannot terminate, even when for any finite input the fold just returns the initial accumulator:

    >>> foldl (\a _ -> a) 0 $ repeat 1
    * Hangs forever *

WARNING: When it comes to lists, you always want to use either `foldl'` or `foldr` instead.

foldr1 :: (a -> a -> a) -> t a -> a #

A variant of `foldr` that has no base case, and thus may only be applied to non-empty structures.

This function is non-total and will raise a runtime exception if the structure happens to be empty.

#### Examples

Expand

Basic usage:

    >>> foldr1 (+) [1..4]
    10

    >>> foldr1 (+) []
    Exception: Prelude.foldr1: empty list

    >>> foldr1 (+) Nothing
    *** Exception: foldr1: empty structure

    >>> foldr1 (-) [1..4]
    -2

    >>> foldr1 (&&) [True, False, True, True]
    False

    >>> foldr1 (||) [False, False, True, True]
    True

    * Hangs forever *

foldl1 :: (a -> a -> a) -> t a -> a #

A variant of `foldl` that has no base case, and thus may only be applied to non-empty structures.

This function is non-total and will raise a runtime exception if the structure happens to be empty.

    foldl1 f = foldl1 f . toList

#### Examples

Basic usage:

    >>> foldl1 (+) [1..4]
    10

    >>> foldl1 (+) []

    False

    >>> foldl1 (||) [False, False, True, True]
    True

    >>> foldl1 (+) [1..]
    * Hangs forever *

null :: t a -> Bool #

Test whether the structure is empty. The default implementation is Left-associative and lazy in both the initial element and the accumulator. Thus optimised for structures where the first element can be accessed in constant time. Structures where this is not the case should have a non-default implementation.

#### Examples

Expand

Basic usage:

    >>> null []
    True

    >>> null [1]
    False

`null` is expected to terminate even for infinite structures. The default implementation terminates provided the structure is bounded on the left (there is a leftmost element).

    >>> null [1..]
    False

Since: base-4.8.0.0

length :: t a -> Int #

Returns the size/length of a finite structure as an `Int`. The default implementation just counts elements starting with the leftmost. Instances for structures that can compute the element count faster than via element-by-element counting, should provide a specialised implementation.

#### Examples

Expand

Basic usage:

    >>> length []
    0

    >>> length ['a', 'b', 'c']
    3
    >>> length [1..]
    * Hangs forever *

Since: base-4.8.0.0

elem :: Eq a => a -> t a -> Bool infix 4 #

Does the element occur in the structure?

Note: `elem` is often used in infix form.

#### Examples

Expand

Basic usage:

    >>> 3 `elem` []
    False

    >>> 3 `elem` [1,2]
    False

    >>> 3 `elem` [1,2,3,4,5]
    True

For infinite structures, the default implementation of `elem` terminates if the sought-after value exists at a finite distance from the left side of the structure:

    >>> 3 `elem` [1..]
    True

    >>> 3 `elem` ([4..] ++ [3])
    * Hangs forever *

Since: base-4.8.0.0

maximum :: Ord a => t a -> a #

The largest element of a non-empty structure.

This function is non-total and will raise a runtime exception if the structure happens to be empty. A structure that supports random access and maintains its elements in order should provide a specialised implementation to return the maximum in faster than linear time.

#### Examples

Expand

Basic usage:

    >>> maximum [1..10]
    10

    >>> maximum []
    *** Exception: Prelude.maximum: empty list

    >>> maximum Nothing
    *** Exception: maximum: empty structure

WARNING: This function is partial for possibly-empty structures like lists.

Since: base-4.8.0.0

minimum :: Ord a => t a -> a #

The least element of a non-empty structure.

This function is non-total and will raise a runtime exception if the structure happens to be empty. A structure that supports random access and maintains its elements in order should provide a specialised implementation to return the minimum in faster than linear time.

class Show a where #

Conversion of values to readable `String`s.

Derived instances of `Show` have the following properties, which are compatible with derived instances of `Read`:

- The result of `show` is a syntactically correct Haskell expression containing only constants, given the fixity declarations in force at the point where the type is declared. It contains only the constructor names defined in the data type, parentheses, and spaces. When labelled constructor fields are used, braces, commas, field names, and equal signs are also used.
- If the constructor is defined to be an infix operator, then `showsPrec` will produce infix applications of the constructor.
- the representation will be enclosed in parentheses if the precedence of the top-level constructor in `x` is less than `d` (associativity is ignored). Thus, if `d` is `0` then the result is never surrounded in parentheses; if `d` is `11` it is always surrounded in parentheses, unless it is an atomic expression.
- If the constructor is defined using record syntax, then `show` will produce the record-syntax form, with the fields given in the same order as the original declaration.

For example, given the declarations

    infixr 5 :^:
    data Tree a =  Leaf a  |  Tree a :^: Tree a

the derived instance of `Show` is equivalent to

    instance (Show a) => Show (Tree a) where

           showsPrec d (Leaf m) = showParen (d > app_prec) $
                showString "Leaf " . showsPrec (app_prec+1) m
             where app_prec = 10

           showsPrec d (u :^: v) = showParen (d > up_prec) $
                showsPrec (up_prec+1) u .
                showString " :^: "      .
                showsPrec (up_prec+1) v
             where up_prec = 5

Note that right-associativity of `:^:` is ignored. For example,

- ``show` (Leaf 1 :^: Leaf 2 :^: Leaf 3)` produces the string `"Leaf 1 :^: (Leaf 2 :^: Leaf 3)"`.

Methods

showsPrec #

Arguments

:: Int | the operator precedence of the enclosing context (a number from `0` to `11`). Function application has precedence `10`.
-> a | the value to be converted to a `String`
-> ShowS |

Convert a value to a readable `String`.

`showsPrec` should satisfy the law

    showsPrec d x r ++ s  ==  showsPrec d x (r ++ s)

Derived instances of `Read` and `Show` satisfy the following:

- `(x,"")` is an element of `(`readsPrec` d (`showsPrec` d x ""))`.

That is, `readsPrec` parses the string produced by `showsPrec`, and delivers the value that `showsPrec` started with.

show :: a -> String #

A specialised variant of `showsPrec`, using precedence context zero, and returning an ordinary `String`.

showList :: [a] -> ShowS #

The method `showList` is provided to allow the programmer to give a specialised way of showing lists of values. For example, this is used by the predefined `Show` instance of the `Char` type, where values of type `String` should be shown in double quotes, rather than between square brackets.

even :: Integral a => a -> Bool #

(<$>) :: Functor f => (a -> b) -> f a -> f b infixl 4 #

An infix synonym for `fmap`.

The name of this operator is an allusion to `$`. Note the similarities between their types:

     ($)  ::              (a -> b) ->   a ->   b
    (<$>) :: Functor f => (a -> b) -> f a -> f b

Whereas `$` is function application, `<$>` is function application lifted over a `Functor`.

#### Examples

Expand

Convert from a ``Maybe` `Int`` to a ``Maybe` `String`` using `show`:

    >>> show <$> Nothing
    Nothing
    >>> show <$> Just 3
    Just "3"

Convert from an ``Either` `Int` `Int`` to an ``Either` `Int`` `String` using `show`:

    >>> show <$> Left 17
    Left 17
    >>> show <$> Right 17
    Right "17"

Double each element of a list:

    >>> (*2) <$> [1,2,3]
    [2,4,6]

Apply `even` to the second element of a pair:

    >>> even <$> (2,2)
    (2,True)

class Enum a where #

Class `Enum` defines operations on sequentially ordered types.

The `enumFrom`... methods are used in Haskell's translation of arithmetic sequences.

Instances of `Enum` may be derived for any enumeration type (types whose constructors have no fields). The nullary constructors are assumed to be numbered left-to-right by `fromEnum` from `0` through `n-1`. See Chapter 10 of the Haskell Report for more details.

For any type that is an instance of class `Bounded` as well as `Enum`, the following should hold:

- The calls ``succ` `maxBound`` and ``pred` `minBound`` should result in a runtime error.
- `fromEnum` and `toEnum` should give a runtime error if the result value is not representable in the result type. For example, ``toEnum` 7 :: `Bool`` is an error.
- `enumFrom` and `enumFromThen` should be defined with an implicit bound, thus:

       enumFrom     x   = enumFromTo     x maxBound
       enumFromThen x y = enumFromThenTo x y bound
         where
           bound | fromEnum y >= fromEnum x = maxBound
                 | otherwise                = minBound

Methods

succ :: a -> a #

the successor of a value. For numeric types, `succ` adds 1.

pred :: a -> a #

the predecessor of a value. For numeric types, `pred` subtracts 1.

toEnum :: Int -> a #

Convert from an `Int`.

fromEnum :: a -> Int #

Convert to an `Int`. It is implementation-dependent what `fromEnum` returns when applied to a value that is too large to fit in an `Int`.

enumFrom :: a -> [a] #

Used in Haskell's translation of `[n..]` with `[n..] = enumFrom n`, a possible implementation being `enumFrom n = n : enumFrom (succ n)`. For example:

-     enumFrom 4 :: [Integer] = [4,5,6,7,...]

-     enumFrom 6 :: [Int] = [6,7,8,9,...,maxBound :: Int]

enumFromThen :: a -> a -> [a] #

Used in Haskell's translation of `[n,n'..]` with `[n,n'..] = enumFromThen n n'`, a possible implementation being `enumFromThen n n' = n : n' : worker (f x) (f x n')`, `worker s v = v : worker s (s v)`, `x = fromEnum n' - fromEnum n` and `f n y | n > 0 = f (n - 1) (succ y) | n < 0 = f (n + 1) (pred y) | otherwise = y` For example:

-     enumFromThen 4 6 :: [Integer] = [4,6,8,10...]

-     enumFromThen 6 2 :: [Int] = [6,2,-2,-6,...,minBound :: Int]

enumFromTo :: a -> a -> [a] #

Used in Haskell's translation of `[n..m]` with `[n..m] = enumFromTo n m`, a possible implementation being `enumFromTo n m | n <= m = n : enumFromTo (succ n) m | otherwise = []`. For example:

-     enumFromTo 6 10 :: [Int] = [6,7,8,9,10]

-     enumFromTo 42 1 :: [Integer] = []

enumFromThenTo :: a -> a -> a -> [a] #

Used in Haskell's translation of `[n,n'..m]` with `[n,n'..m] = enumFromThenTo n n' m`, a possible implementation being `enumFromThenTo n n' m = worker (f x) (c x) n m`, `x = fromEnum n' - fromEnum n`, `c x = bool (>=) ((x 0)` `f n y | n > 0 = f (n - 1) (succ y) | n < 0 = f (n + 1) (pred y) | otherwise = y` and `worker s c v m | c v m = v : worker s c (s v) m | otherwise = []` For example:

-     enumFromThenTo 4 2 -6 :: [Integer] = [4,2,0,-2,-4,-6]

-     enumFromThenTo 6 8 2 :: [Int] = []

Enum (Fixed a) | Recall that, for numeric types, `succ` and `pred` typically add and subtract `1`, respectively. This is not true in the case of `Fixed`, whose successor and predecessor functions intuitively return the "next" and "previous" values in the enumeration. The results of these functions thus depend on the resolution of the `Fixed` value. For example, when enumerating values of resolution `10^-3` of `type Milli = Fixed E3`,
      succ (0.000 :: Milli) == 0.001
and likewise
      pred (0.000 :: Milli) == -0.001
In other words, `succ` and `pred` increment and decrement a fixed-precision value by the least amount such that the value's resolution is unchanged. For example, `10^-12` is the smallest (positive) amount that can be added to a value of `type Pico = Fixed E12` without changing its resolution, and so
      succ (0.000000000000 :: Pico) == 0.000000000001
and similarly
      pred (0.000000000000 :: Pico) == -0.000000000001
This is worth bearing in mind when defining `Fixed` arithmetic sequences. In particular, you may be forgiven for thinking the sequence
      [1..10] :: [Pico]
evaluates to `[1, 2, 3, 4, 5, 6, 7, 8, 9, 10] :: [Pico]`. However, this is not true. On the contrary, similarly to the above implementations of `succ` and `pred`, `enumFromTo :: Pico -> Pico -> [Pico]` has a "step size" of `10^-12`. Hence, the list `[1..10] :: [Pico]` has the form
      [1.000000000000, 1.00000000001, 1.00000000002, ..., 10.000000000000]
and contains `9 * 10^12 + 1` values. Since: base-2.1

($) :: (a -> b) -> a -> b infixr 0 #

``($)`` is the function application operator.

Applying ``($)`` to a function `f` and an argument `x` gives the same result as applying `f` to `x` directly. The definition is akin to this:

    ($) :: (a -> b) -> a -> b
    ($) f x = f x

This is ``id`` specialized from `a -> a` to `(a -> b) -> (a -> b)` which by the associativity of `(->)` is the same as `(a -> b) -> a -> b`.

On the face of it, this may appear pointless! But it's actually one of the most useful and important operators in Haskell.

The order of operations is very different between `($)` and normal function application. Normal function application has precedence 10 - higher than any operator - and associates to the left. So these two definitions are equivalent:

    expr = min 5 1 + 5
    expr = ((min 5) 1) + 5

`($)` has precedence 0 (the lowest) and associates to the right, so these are equivalent:

    expr = min 5 $ 1 + 5
    expr = (min 5) (1 + 5)

#### Examples

Expand

A common use cases of `($)` is to avoid parentheses in complex expressions.

For example, instead of using nested parentheses in the following Haskell function:

    -- | Sum numbers in a string: strSum "100  5 -7" == 98
    strSum :: String -> Int
    strSum s = sum (mapMaybe readMaybe (words s))

we can deploy the function application operator:

    -- | Sum numbers in a string: strSum "100  5 -7" == 98
    strSum :: String -> Int
    strSum s = sum $ mapMaybe readMaybe $ words s

`($)` is also used as a section (a partially applied operator), in order to indicate that we wish to apply some yet-unspecified function to a given value. For example, to apply the argument `5` to a list of functions:

    applyFive :: [Int]
    applyFive = map ($ 5) [(+1), (2^)]
    >>> [6, 32]

#### Technical Remark (Representation Polymorphism)

Expand

`($)` is fully representation-polymorphic. This allows it to also be used with arguments of unlifted and even unboxed kinds, such as unboxed integers:

    fastMod :: Int -> Int -> Int
    fastMod (I# x) (I# m) = I# $ remInt# x m

type String = [Char] #

`String` is an alias for a list of characters.

String constants in Haskell are values of type `String`. That means if you write a string literal like `"hello world"`, it will have the type `[Char]`, which is the same as `String`.

Note: You can ask the compiler to automatically infer different types with the `-XOverloadedStrings` language extension, for example `"hello world" :: Text`. See `IsString` for more information.

Because `String` is just a list of characters, you can use normal list functions to do basic string manipulation. See Data.List for operations on lists.

### Performance considerations

Expand

`[Char]` is a relatively memory-inefficient type. It is a linked list of boxed word-size characters, internally it looks something like:

    ╭─────┬───┬──╮  ╭─────┬───┬──╮  ╭─────┬───┬──╮  ╭────╮
    │ (:) │   │ ─┼─>│ (:) │   │ ─┼─>│ (:) │   │ ─┼─>│ [] │
    ╰─────┴─┼─┴──╯  ╰─────┴─┼─┴──╯  ╰─────┴─┼─┴──╯  ╰────╯
            v               v               v
           'a'             'b'             'c'

The `String` "abc" will use `5*3+1 = 16` (in general `5n+1`) words of space in memory.

Furthermore, operations like `(++)` (string concatenation) are `O(n)` (in the left argument).

For historical reasons, the `base` library uses `String` in a lot of places for the conceptual simplicity, but library code dealing with user-data should use the text package for Unicode text, or the the bytestring package for binary data.

unzip :: [(a, b)] -> ([a], [b]) #

`unzip` transforms a list of pairs into a list of first components and a list of second components.

#### Examples

Expand

    >>> unzip []
    ([],[])

    >>> unzip [(1, 'a'), (2, 'b')]
    ([1,2],"ab")

repeat :: a -> [a] #

`repeat` `x` is an infinite list, with `x` the value of every element.

#### Examples

Expand

    >>> take 10 $ repeat 17
    [17,17,17,17,17,17,17,17,17, 17]

    >>> repeat undefined
    [*** Exception: Prelude.undefined

cycle :: HasCallStack => [a] -> [a] #

`cycle` ties a finite list into a circular one, or equivalently, the infinite repetition of the original list. It is the identity on infinite lists.

#### Examples

Expand

    >>> cycle []
    *** Exception: Prelude.cycle: empty list

    >>> take 10 (cycle [42])
    [42,42,42,42,42,42,42,42,42,42]

    >>> take 10 (cycle [2, 5, 7])
    [2,5,7,2,5,7,2,5,7,2]

    >>> take 1 (cycle (42 : undefined))
    [42]

class Applicative m => Monad (m :: Type -> Type) where #

The `Monad` class defines the basic operations over a monad, a concept from a branch of mathematics known as category theory. From the perspective of a Haskell programmer, however, it is best to think of a monad as an abstract datatype of actions. Haskell's `do` expressions provide a convenient syntax for writing monadic expressions.

Instances of `Monad` should satisfy the following:

Left identity
  ``return` a `>>=` k = k a`
Right identity
  `m `>>=` `return` = m`
Associativity
  `m `>>=` (\x -> k x `>>=` h) = (m `>>=` k) `>>=` h`

Furthermore, the `Monad` and `Applicative` operations should relate as follows:

-     pure = return

-     m1 <*> m2 = m1 >>= (\x1 -> m2 >>= (\x2 -> return (x1 x2)))

The above laws imply:

-     fmap f xs  =  xs >>= return . f

-     (>>) = (*>)

and that `pure` and (`<*>`) satisfy the applicative functor laws.

The instances of `Monad` for lists, `Maybe` and `IO` defined in the Prelude satisfy these laws.

Minimal complete definition

(>>=)

Methods

(>>=) :: m a -> (a -> m b) -> m b infixl 1 #

Sequentially compose two actions, passing any value produced by the first as an argument to the second.

'`as `>>=` bs`' can be understood as the `do` expression

    do a <- as
       bs a

return :: a -> m a #

Inject a value into the monadic type.

class Read a where #

Parsing of `String`s, producing values.

Derived instances of `Read` make the following assumptions, which derived instances of `Show` obey:

- If the constructor is defined to be an infix operator, then the derived `Read` instance will parse only infix applications of the constructor (not the prefix form).
- Associativity is not used to reduce the occurrence of parentheses, although precedence may be.
- If the constructor is defined using record syntax, the derived `Read` will parse only the record-syntax form, and furthermore, the fields must be given in the same order as the original declaration.
- The derived `Read` instance allows arbitrary Haskell whitespace between tokens of the input string. Extra parentheses are also allowed.

For example, given the declarations

    infixr 5 :^:
    data Tree a =  Leaf a  |  Tree a :^: Tree a

the derived instance of `Read` in Haskell 2010 is equivalent to

    instance (Read a) => Read (Tree a) where

            readsPrec d r =  readParen (d > app_prec)
                             (\r -> [(Leaf m,t) |
                                     ("Leaf",s) <- lex r,
                                     (m,t) <- readsPrec (app_prec+1) s]) r

                          ++ readParen (d > up_prec)
                             (\r -> [(u:^:v,w) |
                                     (u,s) <- readsPrec (up_prec+1) r,
                                     (":^:",t) <- lex s,
                                     (v,w) <- readsPrec (up_prec+1) t]) r

              where app_prec = 10
                    up_prec = 5

Note that right-associativity of `:^:` is unused.

The derived instance in GHC is equivalent to

    instance (Read a) => Read (Tree a) where

            readPrec = parens $ (prec app_prec $ do
                                     Ident "Leaf" <- lexP
                                     m <- step readPrec
                                     return (Leaf m))

                         +++ (prec up_prec $ do
                                     u <- step readPrec
                                     Symbol ":^:" <- lexP
                                     v <- step readPrec
                                     return (u :^: v))

              where app_prec = 10
                    up_prec = 5

            readListPrec = readListPrecDefault

Why do both `readsPrec` and `readPrec` exist, and why does GHC opt to implement `readPrec` in derived `Read` instances instead of `readsPrec`? The reason is that `readsPrec` is based on the `ReadS` type, and although `ReadS` is mentioned in the Haskell 2010 Report, it is not a very efficient parser data structure.

`readPrec`, on the other hand, is based on a much more efficient `ReadPrec` datatype (a.k.a "new-style parsers"), but its definition relies on the use of the `RankNTypes` language extension. Therefore, `readPrec` (and its cousin, `readListPrec`) are marked as GHC-only. Nevertheless, it is recommended to use `readPrec` instead of `readsPrec` whenever possible for the efficiency improvements it brings.

As mentioned above, derived `Read` instances in GHC will implement `readPrec` instead of `readsPrec`. The default implementations of `readsPrec` (and its cousin, `readList`) will simply use `readPrec` under the hood. If you are writing a `Read` instance by hand, it is recommended to write it like so:

    instance Read T where
      readPrec     = ...
      readListPrec = readListPrecDefault

Minimal complete definition

readsPrec | readPrec

Methods

readsPrec #

Arguments

:: Int | the operator precedence of the enclosing context (a number from `0` to `11`). Function application has precedence `10`.
-> ReadS a |

attempts to parse a value from the front of the string, returning a list of (parsed value, remaining string) pairs. If there is no successful parse, the returned list is empty.

Derived instances of `Read` and `Show` satisfy the following:

- `(x,"")` is an element of `(`readsPrec` d (`showsPrec` d x ""))`.

That is, `readsPrec` parses the string produced by `showsPrec`, and delivers the value that `showsPrec` started with.

readList :: ReadS [a] #

The method `readList` is provided to allow the programmer to give a specialised way of parsing lists of values. For example, this is used by the predefined `Read` instance of the `Char` type, where values of type `String` are expected to use double quotes, rather than square brackets.

uncurry :: (a -> b -> c) -> (a, b) -> c #

`uncurry` converts a curried function to a function on pairs.

#### Examples

Expand

    >>> uncurry (+) (1,2)
    3

    >>> uncurry ($) (show, 1)
    "1"

    >>> map (uncurry max) [(1,2), (3,4), (6,8)]
    [2,4,8]

id :: a -> a #

Identity function.

    id x = x

This function might seem useless at first glance, but it can be very useful in a higher order context.

#### Examples

Expand

    >>> length $ filter id [True, True, False, True]
    3

    >>> Just (Just 3) >>= id
    Just 3

    >>> foldr id 0 [(^3), (*5), (+2)]
    1000

head :: HasCallStack => [a] -> a #

\(\mathcal{O}(1)\). Extract the first element of a list, which must be non-empty.

##### Examples

Expand

    >>> head [1, 2, 3]
    1

    >>> head [1..]
    1

    >>> head []
    *** Exception: Prelude.head: empty list

class (Functor t, Foldable t) => Traversable (t :: Type -> Type) where #

Functors representing data structures that can be transformed to structures of the same shape by performing an `Applicative` (or, therefore, `Monad`) action on each element from left to right.

A more detailed description of what same shape means, the various methods, how traversals are constructed, and example advanced use-cases can be found in the Overview section of Data.Traversable.

For the class laws see the Laws section of Data.Traversable.

traverse | sequenceA

Methods

traverse :: Applicative f => (a -> f b) -> t a -> f (t b) #

Map each element of a structure to an action, evaluate these actions from left to right, and collect the results. For a version that ignores the results see `traverse_`.

#### Examples

Expand

Basic usage:

In the first two examples we show each evaluated action mapping to the output structure.

    >>> traverse Just [1,2,3,4]
    Just [1,2,3,4]

    >>> traverse id [Right 1, Right 2, Right 3, Right 4]
    Right [1,2,3,4]

In the next examples, we show that `Nothing` and `Left` values short circuit the created structure.

    >>> traverse (const Nothing) [1,2,3,4]
    Nothing

    >>> traverse (\x -> if odd x then Just x else Nothing)  [1,2,3,4]
    Nothing

    >>> traverse id [Right 1, Right 2, Right 3, Right 4, Left 0]
    Left 0

sequenceA :: Applicative f => t (f a) -> f (t a) #

Evaluate each action in the structure from left to right, and collect the results. For a version that ignores the results see `sequenceA_`.

#### Examples

Expand

Basic usage:

For the first two examples we show sequenceA fully evaluating a a structure and collecting the results.

    >>> sequenceA [Just 1, Just 2, Just 3]
    Just [1,2,3]

    >>> sequenceA [Right 1, Right 2, Right 3]
    Right [1,2,3]

The next two example show `Nothing` and `Just` will short circuit the resulting structure if present in the input. For more context, check the `Traversable` instances for `Either` and `Maybe`.

    >>> sequenceA [Just 1, Just 2, Just 3, Nothing]
    Nothing

    >>> sequenceA [Right 1, Right 2, Right 3, Left 4]
    Left 4

mapM :: Monad m => (a -> m b) -> t a -> m (t b) #

Map each element of a structure to a monadic action, evaluate these actions from left to right, and collect the results. For a version that ignores the results see `mapM_`.

#### Examples

Expand

`mapM` is literally a `traverse` with a type signature restricted to `Monad`. Its implementation may be more efficient due to additional power of `Monad`.

sequence :: Monad m => t (m a) -> m (t a) #

Evaluate each monadic action in the structure from left to right, and collect the results. For a version that ignores the results see `sequence_`.

#### Examples

Expand

Basic usage:

The first two examples are instances where the input and and output of `sequence` are isomorphic.

    >>> sequence $ Right [1,2,3,4]
    [Right 1,Right 2,Right 3,Right 4]

    >>> sequence $ [Right 1,Right 2,Right 3,Right 4]
    Right [1,2,3,4]

The following examples demonstrate short circuit behavior for `sequence`.

    >>> sequence $ Left [1,2,3,4]
    Left [1,2,3,4]

    >>> sequence $ [Left 0, Right 1,Right 2,Right 3,Right 4]
    Left 0

type IOError = IOException #

The Haskell 2010 type for exceptions in the `IO` monad. Any I/O operation may raise an `IOError` instead of returning a result. For a more general type of exception, including also those that arise in pure code, see `Exception`.

In Haskell 2010, this is an opaque type.

writeFile :: FilePath -> String -> IO () #

The computation `writeFile` `file str` function writes the string `str`, to the file `file`.

getLine :: IO String #

Read a line from the standard input device (same as `hGetLine` `stdin`).

putStrLn :: String -> IO () #

The same as `putStr`, but adds a newline character.

mapM_ :: (Foldable t, Monad m) => (a -> m b) -> t a -> m () #

Map each element of a structure to a monadic action, evaluate these actions from left to right, and ignore the results. For a version that doesn't ignore the results see `mapM`.

`mapM_` is just like `traverse_`, but specialised to monadic actions.

sequence_ :: (Foldable t, Monad m) => t (m a) -> m () #

Evaluate each monadic action in the structure from left to right, and ignore the results. For a version that doesn't ignore the results see `sequence`.

`sequence_` is just like `sequenceA_`, but specialised to monadic actions.

filter :: (a -> Bool) -> [a] -> [a] #

\(\mathcal{O}(n)\). `filter`, applied to a predicate and a list, returns the list of those elements that satisfy the predicate; i.e.,

    filter p xs = [ x | x <- xs, p x]

#### Examples

Expand

    >>> filter odd [1, 2, 3]
    [1,3]

    >>> filter (\l -> length l > 3) ["Hello", ", ", "World", "!"]
    ["Hello","World"]

    >>> filter (/= 3) [1, 2, 3, 4, 3, 2, 1]
    [1,2,4,2,1]

const :: a -> b -> a #

`const x y` always evaluates to `x`, ignoring its second argument.

    const x = \_ -> x

This function might seem useless at first glance, but it can be very useful in a higher order context.

#### Examples

Expand

    >>> const 42 "hello"
    42

    >>> map (const 42) [0..3]
    [42,42,42,42]

(++) :: [a] -> [a] -> [a] infixr 5 #

`(++)` appends two lists, i.e.,

    [x1, ..., xm] ++ [y1, ..., yn] == [x1, ..., xm, y1, ..., yn]
    [x1, ..., xm] ++ [y1, ...] == [x1, ..., xm, y1, ...]

If the first list is not finite, the result is the first list.

#### Performance considerations

Expand

This function takes linear time in the number of elements of the first list. Thus it is better to associate repeated applications of `(++)` to the right (which is the default behaviour): `xs ++ (ys ++ zs)` or simply `xs ++ ys ++ zs`, but not `(xs ++ ys) ++ zs`. For the same reason `concat` `=` `foldr` `(++)` `[]` has linear performance, while `foldl` `(++)` `[]` is prone to quadratic slowdown

#### Examples

Expand

    >>> [1, 2, 3] ++ [4, 5, 6]
    [1,2,3,4,5,6]

    >>> [] ++ [1, 2, 3]
    [1,2,3]

    >>> [3, 2, 1] ++ []
    [3,2,1]

seq :: a -> b -> b infixr 0 #

The value of ``seq` a b` is bottom if `a` is bottom, and otherwise equal to `b`. In other words, it evaluates the first argument `a` to weak head normal form (WHNF). `seq` is usually introduced to improve performance by avoiding unneeded laziness.

A note on evaluation order: the expression ``seq` a b` does not guarantee that `a` will be evaluated before `b`. The only guarantee given by `seq` is that the both `a` and `b` will be evaluated before `seq` returns a value. In particular, this means that `b` may be evaluated before `a`. If you need to guarantee a specific order of evaluation, you must use the function `pseq` from the "parallel" package.

zip :: [a] -> [b] -> [(a, b)] #

\(\mathcal{O}(\min(m,n))\). `zip` takes two lists and returns a list of corresponding pairs.

`zip` is right-lazy:

    >>> zip [] undefined
    []
    >>> zip undefined []
    *** Exception: Prelude.undefined
    ...

`zip` is capable of list fusion, but it is restricted to its first list argument and its resulting list.

#### Examples

Expand

    >>> zip [1, 2, 3] ['a', 'b', 'c']
    [(1,'a'),(2,'b'),(3,'c')]

If one input list is shorter than the other, excess elements of the longer list are discarded, even if one of the lists is infinite:

    >>> zip [1] ['a', 'b']
    [(1,'a')]

    >>> zip [1, 2] ['a']
    [(1,'a')]

    >>> zip [] [1..]
    []

    >>> zip [1..] []
    []

print :: Show a => a -> IO () #

The `print` function outputs a value of any printable type to the standard output device. Printable types are those that are instances of class `Show`; `print` converts values to strings for output using the `show` operation and adds a newline.

For example, a program to print the first 20 integers and their powers of 2 could be written as:

    main = print ([(n, 2^n) | n <- [0..19]])

otherwise :: Bool #

`otherwise` is defined as the value `True`. It helps to make guards more readable. eg.

     f x | x < 0     = ...
         | otherwise = ...

map :: (a -> b) -> [a] -> [b] #

\(\mathcal{O}(n)\). `map` `f xs` is the list obtained by applying `f` to each element of `xs`, i.e.,

    map f [x1, x2, ..., xn] == [f x1, f x2, ..., f xn]
    map f [x1, x2, ...] == [f x1, f x2, ...]

this means that `map id == id`

#### Examples

Expand

    >>> map (+1) [1, 2, 3]
    [2,3,4]

    >>> map id [1, 2, 3]
    [1,2,3]

    >>> map (\n -> 3 * n + 1) [1, 2, 3]
    [4,7,10]

class Num a where #

Basic numeric class.

The Haskell Report defines no laws for `Num`. However, `(`+`)` and `(`*`)` are customarily expected to define a ring and have the following properties:

Associativity of `(`+`)`
  `(x + y) + z` = `x + (y + z)`
Commutativity of `(`+`)`
  `x + y` = `y + x`
``fromInteger` 0` is the additive identity
  `x + fromInteger 0` = `x`
`negate` gives the additive inverse
  `x + negate x` = `fromInteger 0`
Associativity of `(`*`)`
  `(x * y) * z` = `x * (y * z)`
``fromInteger` 1` is the multiplicative identity
  `x * fromInteger 1` = `x` and `fromInteger 1 * x` = `x`
Distributivity of `(`*`)` with respect to `(`+`)`
  `a * (b + c)` = `(a * b) + (a * c)` and `(b + c) * a` = `(b * a) + (c * a)`
Coherence with `toInteger`
  if the type also implements `Integral`, then `fromInteger` is a left inverse for `toInteger`, i.e. `fromInteger (toInteger i) == i`

Note that it isn't customarily expected that a type instance of both `Num` and `Ord` implement an ordered ring. Indeed, in `base` only `Integer` and `Rational` do.

Minimal complete definition

(+), (*), abs, signum, fromInteger, (negate | (-))

Methods

(+) :: a -> a -> a infixl 6 #

(-) :: a -> a -> a infixl 6 #

(*) :: a -> a -> a infixl 7 #

negate :: a -> a #

Unary negation.

abs :: a -> a #

Absolute value.

signum :: a -> a #

Sign of a number. The functions `abs` and `signum` should satisfy the law:

    abs x * signum x == x

For real numbers, the `signum` is either `-1` (negative), `0` (zero) or `1` (positive).

fromInteger :: Integer -> a #

Conversion from an `Integer`. An integer literal represents the application of the function `fromInteger` to the appropriate value of type `Integer`, so such literals have type `(`Num` a) => a`.

class Eq a where #

The `Eq` class defines equality (`==`) and inequality (`/=`). All the basic datatypes exported by the Prelude are instances of `Eq`, and `Eq` may be derived for any datatype whose constituents are also instances of `Eq`.

The Haskell Report defines no laws for `Eq`. However, instances are encouraged to follow these properties:

Reflexivity
  `x == x` = `True`
Symmetry
  `x == y` = `y == x`
Transitivity
  if `x == y && y == z` = `True`, then `x == z` = `True`
Extensionality
  if `x == y` = `True` and `f` is a function whose return type is an instance of `Eq`, then `f x == f y` = `True`
Negation
  `x /= y` = `not (x == y)`

Minimal complete definition: either `==` or `/=`.

class Eq a => Ord a where #

The `Ord` class is used for totally ordered datatypes.

Instances of `Ord` can be derived for any user-defined datatype whose constituent types are in `Ord`. The declared order of the constructors in the data declaration determines the ordering in derived `Ord` instances. The `Ordering` datatype allows a single comparison to determine the precise ordering of two objects.

`Ord`, as defined by the Haskell report, implements a total order and has the following properties:

Comparability
  `x <= y || y <= x` = `True`
Transitivity
  if `x <= y && y <= z` = `True`, then `x <= z` = `True`
Reflexivity
  `x <= x` = `True`
Antisymmetry
  if `x <= y && y <= x` = `True`, then `x == y` = `True`

The following operator interactions are expected to hold:

1. `x >= y` = `y <= x`
2. `x < y` = `x <= y && x /= y`
3. `x > y` = `y < x`
4. `x < y` = `compare x y == LT`
5. `x > y` = `compare x y == GT`
6. `x == y` = `compare x y == EQ`
7. `min x y == if x <= y then x else y` = `True`
8. `max x y == if x >= y then x else y` = `True`

Note that (7.) and (8.) do not require `min` and `max` to return either of their arguments. The result is merely required to equal one of the arguments in terms of `(==)`.

Minimal complete definition: either `compare` or `<=`. Using `compare` can be more efficient for complex types.

Ord Double | IEEE 754 `Double`-precision type includes not only numbers, but also positive and negative infinities and a special element called `NaN` (which can be quiet or signal). IEEE 754-2008, section 5.11 requires that if at least one of arguments of `<=`, `<`, `>`, `>=` is `NaN` then the result of the comparison is `False`, and `instance` `Ord` `Double` complies with this requirement. This violates the reflexivity: both `NaN` `<=` `NaN` and `NaN` `>=` `NaN` are `False`. IEEE 754-2008, section 5.10 defines `totalOrder` predicate. Unfortunately, `compare` on `Double`s violates the IEEE standard and does not define a total order. More specifically, both `compare` `NaN` `x` and `compare` `x` `NaN` always return `GT`. Thus, users must be extremely cautious when using `instance` `Ord` `Double`. For instance, one should avoid ordered containers with keys represented by `Double`, because data loss and corruption may happen. An IEEE-compliant `compare` is available in `fp-ieee` package as `TotallyOrdered` newtype. Moving further, the behaviour of `min` and `max` with regards to `NaN` is also non-compliant. IEEE 754-2008, section 5.3.1 defines that quiet `NaN` should be treated as a missing data by `minNum` and `maxNum` functions, for example, `minNum(NaN, 1) = minNum(1, NaN) = 1`. Some languages such as Java deviate from the standard implementing `minNum(NaN, 1) = minNum(1, NaN) = NaN`. However, `min` / `max` in `base` are even worse: `min` `NaN` 1 is 1, but `min` 1 `NaN` is `NaN`. IEEE 754-2008 compliant `min` / `max` can be found in `ieee754` package under `minNum` / `maxNum` names. Implementations compliant with `minimumNumber` / `maximumNumber` from a newer IEEE 754-2019, section 9.6 are available from `fp-ieee` package.

class Functor (f :: Type -> Type) where #

A type `f` is a Functor if it provides a function `fmap` which, given any types `a` and `b` lets you apply any function from `(a -> b)` to turn an `f a` into an `f b`, preserving the structure of `f`. Furthermore `f` needs to adhere to the following:

Identity
  ``fmap` `id` == `id``
Composition
  ``fmap` (f . g) == `fmap` f . `fmap` g`

Note, that the second law follows from the free theorem of the type `fmap` and the first law, so you need only check that the former condition holds. See https://www.schoolofhaskell.com/user/edwardk/snippets/fmap or https://github.com/quchen/articles/blob/master/second_functor_law.md for an explanation.

Minimal complete definition

fmap

Methods

fmap :: (a -> b) -> f a -> f b #

`fmap` is used to apply a function of type `(a -> b)` to a value of type `f a`, where f is a functor, to produce a value of type `f b`. Note that for any type constructor with more than one parameter (e.g., `Either`), only the last type parameter can be modified with `fmap` (e.g., `b` in `Either a b`).

Some type constructors with two parameters or more have a ``Bifunctor`` instance that allows both the last and the penultimate parameters to be mapped over.

#### Examples

Expand

Convert from a ``Maybe` Int` to a `Maybe String` using `show`:

    >>> fmap show Nothing
    Nothing
    >>> fmap show (Just 3)
    Just "3"

Convert from an ``Either` Int Int` to an `Either Int String` using `show`:

    >>> fmap show (Left 17)
    Left 17
    >>> fmap show (Right 17)
    Right "17"

Double each element of a list:

    >>> fmap (*2) [1,2,3]
    [2,4,6]

Apply `even` to the second element of a pair:

    >>> fmap even (2,2)
    (2,True)

It may seem surprising that the function is only applied to the last element of the tuple compared to the list example above which applies it to every element in the list. To understand, remember that tuples are type constructors with multiple type parameters: a tuple of 3 elements `(a,b,c)` can also be written `(,,) a b c` and its `Functor` instance is defined for `Functor ((,,) a b)` (i.e., only the third parameter is free to be mapped over with `fmap`).

It explains why `fmap` can be used with tuples containing values of different types as in the following example:

    >>> fmap even ("hello", 1.0, 4)
    ("hello",1.0,True)

(<$) :: a -> f b -> f a infixl 4 #

Replace all locations in the input with the same value. The default definition is ``fmap` . `const``, but this may be overridden with a more efficient version.

#### Examples

Expand

Perform a computation with `Maybe` and replace the result with a constant value if it is `Just`:

    >>> 'a' <$ Just 2
    Just 'a'
    >>> 'a' <$ Nothing
    Nothing

class Monad m => MonadFail (m :: Type -> Type) where #

When a value is bound in `do`-notation, the pattern on the left hand side of `<-` might not match. In this case, this class provides a function to recover.

A `Monad` without a `MonadFail` instance may only be used in conjunction with pattern that always match, such as newtypes, tuples, data types with only a single data constructor, and irrefutable patterns (`~pat`).

Instances of `MonadFail` should satisfy the following law: `fail s` should be a left zero for `>>=`,

    fail s >>= f  =  fail s

If your `Monad` is also `MonadPlus`, a popular definition is

    fail _ = mzero

`fail s` should be an action that runs in the monad itself, not an exception (except in instances of `MonadIO`). In particular, `fail` should not be implemented in terms of `error`.

class Semigroup a where #

The class of semigroups (types with an associative binary operation).

Instances should satisfy the following:

Associativity
  `x `<>` (y `<>` z) = (x `<>` y) `<>` z`

You can alternatively define `sconcat` instead of (`<>`), in which case the laws are:

Unit
  ``sconcat` (`pure` x) = x`
Multiplication
  ``sconcat` (`join` xss) = `sconcat` (`fmap` `sconcat` xss)`

class Semigroup a => Monoid a where #

The class of monoids (types with an associative binary operation that has an identity). Instances should satisfy the following:

Right identity
  `x `<>` `mempty` = x`
Left identity
  ``mempty` `<>` x = x`
Associativity
  `x `<>` (y `<>` z) = (x `<>` y) `<>` z` (`Semigroup` law)
Concatenation
  ``mconcat` = `foldr` (`<>`) `mempty``

You can alternatively define `mconcat` instead of `mempty`, in which case the laws are:

Unit
  ``mconcat` (`pure` x) = x`
Multiplication
  ``mconcat` (`join` xss) = `mconcat` (`fmap` `mconcat` xss)`
Subclass
  ``mconcat` (`toList` xs) = `sconcat` xs`

The method names refer to the monoid of lists under concatenation, but there are many other instances.

Some types can be viewed as a monoid in more than one way, e.g. both addition and multiplication on numbers. In such cases we often define `newtype`s and make those instances of `Monoid`, e.g. `Sum` and `Product`.

NOTE: `Semigroup` is a superclass of `Monoid` since base-4.11.0.0.

Minimal complete definition

mempty | mconcat

Methods

mempty :: a #

Identity of `mappend`

#### Examples

Expand

    >>> "Hello world" <> mempty
    "Hello world"

    >>> mempty <> [1, 2, 3]
    [1,2,3]

mappend :: a -> a -> a #

An associative operation

NOTE: This method is redundant and has the default implementation ``mappend` = (`<>`)` since base-4.11.0.0. Should it be implemented manually, since `mappend` is a synonym for (`<>`), it is expected that the two functions are defined the same way. In a future GHC release `mappend` will be removed from `Monoid`.

mconcat :: [a] -> a #

Fold a list using the monoid.

For most types, the default definition for `mconcat` will be used, but the function is included in the class definition so that an optimized version can be provided for specific types.

    >>> mconcat ["Hello", " ", "Haskell", "!"]
    "Hello Haskell!"

class Functor f => Applicative (f :: Type -> Type) where #

A functor with application, providing operations to

- embed pure expressions (`pure`), and
- sequence computations and combine their results (`<*>` and `liftA2`).

A minimal complete definition must include implementations of `pure` and of either `<*>` or `liftA2`. If it defines both, then they must behave the same as their default definitions:

    (<*>) = liftA2 id

    liftA2 f x y = f <$> x <*> y

Further, any definition must satisfy the following:

Identity

      pure id <*> v = v

Composition

      pure (.) <*> u <*> v <*> w = u <*> (v <*> w)

Homomorphism

      pure f <*> pure x = pure (f x)

Interchange

      u <*> pure y = pure ($ y) <*> u

The other methods have the following default definitions, which may be overridden with equivalent specialized implementations:

-     u *> v = (id <$ u) <*> v

-     u <* v = liftA2 const u v

As a consequence of these laws, the `Functor` instance for `f` will satisfy

-     fmap f x = pure f <*> x

It may be useful to note that supposing

    forall x y. p (q x y) = f x . g y

it follows from the above that

    liftA2 p (liftA2 q u v) = liftA2 f u . liftA2 g v

If `f` is also a `Monad`, it should satisfy

-     pure = return

-     m1 <*> m2 = m1 >>= (\x1 -> m2 >>= (\x2 -> return (x1 x2)))

-     (*>) = (>>)

(which implies that `pure` and `<*>` satisfy the applicative functor laws).

Minimal complete definition

pure, ((<*>) | liftA2)

Methods

pure :: a -> f a #

Lift a value.

(<*>) :: f (a -> b) -> f a -> f b infixl 4 #

Sequential application.

A few functors support an implementation of `<*>` that is more efficient than the default one.

#### Example

Expand

Used in combination with `(`<$>`)`, `(`<*>`)` can be used to build a record.

    >>> data MyState = MyState {arg1 :: Foo, arg2 :: Bar, arg3 :: Baz}

    >>> produceFoo :: Applicative f => f Foo

    >>> produceBar :: Applicative f => f Bar
    >>> produceBaz :: Applicative f => f Baz

    >>> mkState :: Applicative f => f MyState
    >>> mkState = MyState <$> produceFoo <*> produceBar <*> produceBaz

liftA2 :: (a -> b -> c) -> f a -> f b -> f c #

Lift a binary function to actions.

Some functors support an implementation of `liftA2` that is more efficient than the default one. In particular, if `fmap` is an expensive operation, it is likely better to use `liftA2` than to `fmap` over the structure and then use `<*>`.

This became a typeclass method in 4.10.0.0. Prior to that, it was a function defined in terms of `<*>` and `fmap`.

#### Example

Expand

    >>> liftA2 (,) (Just 3) (Just 5)
    Just (3,5)

(*>) :: f a -> f b -> f b infixl 4 #

Sequence actions, discarding the value of the first argument.

#### Examples

Expand

If used in conjunction with the Applicative instance for `Maybe`, you can chain Maybe computations, with a possible "early return" in case of `Nothing`.

    >>> Just 2 *> Just 3
    Just 3

    >>> Nothing *> Just 3
    Nothing

Of course a more interesting use case would be to have effectful computations instead of just returning pure values.

    >>> import Data.Char
    >>> import Text.ParserCombinators.ReadP
    >>> let p = string "my name is " *> munch1 isAlpha <* eof
    >>> readP_to_S p "my name is Simon"
    [("Simon","")]

(<*) :: f a -> f b -> f a infixl 4 #

Sequence actions, discarding the value of the second argument.

class Bounded a where #

The `Bounded` class is used to name the upper and lower limits of a type. `Ord` is not a superclass of `Bounded` since types that are not totally ordered may also have upper and lower bounds.

The `Bounded` class may be derived for any enumeration type; `minBound` is the first constructor listed in the `data` declaration and `maxBound` is the last. `Bounded` may also be derived for single-constructor datatypes whose constituent types are in `Bounded`.

class Fractional a => Floating a where #

Trigonometric and hyperbolic functions and related functions.

The Haskell Report defines no laws for `Floating`. However, `(`+`)`, `(`*`)` and `exp` are customarily expected to define an exponential field and have the following properties:

- `exp (a + b)` = `exp a * exp b`
- `exp (fromInteger 0)` = `fromInteger 1`

class (RealFrac a, Floating a) => RealFloat a where #

Efficient, machine-independent access to the components of a floating-point number.

Minimal complete definition

floatRadix, floatDigits, floatRange, decodeFloat, encodeFloat, isNaN, isInfinite, isDenormalized, isNegativeZero, isIEEE

Methods

floatRadix :: a -> Integer #

a constant function, returning the radix of the representation (often `2`)

floatDigits :: a -> Int #

a constant function, returning the number of digits of `floatRadix` in the significand

floatRange :: a -> (Int, Int) #

a constant function, returning the lowest and highest values the exponent may assume

decodeFloat :: a -> (Integer, Int) #

The function `decodeFloat` applied to a real floating-point number returns the significand expressed as an `Integer` and an appropriately scaled exponent (an `Int`). If ``decodeFloat` x` yields `(m,n)`, then `x` is equal in value to `m*b^^n`, where `b` is the floating-point radix, and furthermore, either `m` and `n` are both zero or else `b^(d-1) <= `abs` m < b^d`, where `d` is the value of ``floatDigits` x`. In particular, ``decodeFloat` 0 = (0,0)`. If the type contains a negative zero, also ``decodeFloat` (-0.0) = (0,0)`. The result of ``decodeFloat` x` is unspecified if either of ``isNaN` x` or ``isInfinite` x` is `True`.

encodeFloat :: Integer -> Int -> a #

`encodeFloat` performs the inverse of `decodeFloat` in the sense that for finite `x` with the exception of `-0.0`, ``uncurry` `encodeFloat` (`decodeFloat` x) = x`. ``encodeFloat` m n` is one of the two closest representable floating-point numbers to `m*b^^n` (or `±Infinity` if overflow occurs); usually the closer, but if `m` contains too many bits, the result may be rounded in the wrong direction.

exponent :: a -> Int #

`exponent` corresponds to the second component of `decodeFloat`. ``exponent` 0 = 0` and for finite nonzero `x`, ``exponent` x = snd (`decodeFloat` x) + `floatDigits` x`. If `x` is a finite floating-point number, it is equal in value to ``significand` x * b ^^ `exponent` x`, where `b` is the floating-point radix. The behaviour is unspecified on infinite or `NaN` values.

significand :: a -> a #

The first component of `decodeFloat`, scaled to lie in the open interval (`-1`,`1`), either `0.0` or of absolute value `>= 1/b`, where `b` is the floating-point radix. The behaviour is unspecified on infinite or `NaN` values.

scaleFloat :: Int -> a -> a #

multiplies a floating-point number by an integer power of the radix

isNaN :: a -> Bool #

`True` if the argument is an IEEE "not-a-number" (NaN) value

isInfinite :: a -> Bool #

`True` if the argument is an IEEE infinity or negative infinity

isDenormalized :: a -> Bool #

`True` if the argument is too small to be represented in normalized format

isNegativeZero :: a -> Bool #

`True` if the argument is an IEEE negative zero

isIEEE :: a -> Bool #

`True` if the argument is an IEEE floating point number

atan2 :: a -> a -> a #

a version of arctangent taking two real floating-point arguments. For real floating `x` and `y`, ``atan2` y x` computes the angle (from the positive x-axis) of the vector from the origin to the point `(x,y)`. ``atan2` y x` returns a value in the range [`-pi`, `pi`]. It follows the Common Lisp semantics for the origin when signed zeroes are supported. ``atan2` y 1`, with `y` in a type that is `RealFloat`, should return the same value as ``atan` y`. A default definition of `atan2` is provided, but implementors can provide a more accurate implementation.

raise a number to a non-negative integral power

(&&) :: Bool -> Bool -> Bool infixr 3 #

Boolean "and", lazy in the second argument

(||) :: Bool -> Bool -> Bool infixr 2 #

Boolean "or", lazy in the second argument

Boolean "not"

errorWithoutStackTrace :: [Char] -> a #

A variant of `error` that does not produce a stack trace.

Since: base-4.9.0.0

undefined :: HasCallStack => a #

A special case of `error`. It is expected that compilers will recognize this and insert error messages which are more appropriate to the context in which `undefined` appears.

(=<<) :: Monad m => (a -> m b) -> m a -> m b infixr 1 #

Same as `>>=`, but with the arguments interchanged.

(.) :: (b -> c) -> (a -> b) -> a -> c infixr 9 #

Right to left function composition.

    (f . g) x = f (g x)

    f . id = f = id . f

#### Examples

Expand

    >>> map ((*2) . length) [[], [0, 1, 2], [0]]
    [0,6,2]

    >>> foldr (.) id [(+1), (*3), (^3)] 2
    25

    >>> let (...) = (.).(.) in ((*2)...(+)) 5 10
    30

flip :: (a -> b -> c) -> b -> a -> c #

``flip` f` takes its (first) two arguments in the reverse order of `f`.

    flip f x y = f y x

    flip . flip = id

#### Examples

Expand

    >>> flip (++) "hello" "world"
    "worldhello"

    >>> let (.>) = flip (.) in (+1) .> show $ 5
    "6"

($!) :: (a -> b) -> a -> b infixr 0 #

Strict (call-by-value) application operator. It takes a function and an argument, evaluates the argument to weak head normal form (WHNF), then calls the function with that value.

until :: (a -> Bool) -> (a -> a) -> a -> a #

``until` p f` yields the result of applying `f` until `p` holds.

asTypeOf :: a -> a -> a #

`asTypeOf` is a type-restricted version of `const`. It is usually used as an infix operator, and its typing forces its first argument (which is usually overloaded) to have the same type as the second.

subtract :: Num a => a -> a -> a #

the same as ``flip` (`-`)`.

Because `-` is treated specially in the Haskell grammar, `(-` e`)` is not a section, but an application of prefix negation. However, `(`subtract`` exp`)` is equivalent to the disallowed section.

maybe :: b -> (a -> b) -> Maybe a -> b #

The `maybe` function takes a default value, a function, and a `Maybe` value. If the `Maybe` value is `Nothing`, the function returns the default value. Otherwise, it applies the function to the value inside the `Just` and returns the result.

#### Examples

Expand

Basic usage:

    >>> maybe False odd (Just 3)
    True

    >>> maybe False odd Nothing
    False

Read an integer from a string using `readMaybe`. If we succeed, return twice the integer; that is, apply `(*2)` to it. If instead we fail to parse an integer, return `0` by default:

    >>> import Text.Read ( readMaybe )
    >>> maybe 0 (*2) (readMaybe "5")
    10
    >>> maybe 0 (*2) (readMaybe "")
    0

Apply `show` to a `Maybe Int`. If we have `Just n`, we want to show the underlying `Int` `n`. But if we have `Nothing`, we return the empty string instead of (for example) "Nothing":

    >>> maybe "" show (Just 5)
    "5"
    >>> maybe "" show Nothing
    ""

tail :: HasCallStack => [a] -> [a] #

scanl :: (b -> a -> b) -> b -> [a] -> [b] #

\(\mathcal{O}(n)\). `scanl` is similar to `foldl`, but returns a list of successive reduced values from the left:

    scanl f z [x1, x2, ...] == [z, z `f` x1, (z `f` x1) `f` x2, ...]

    [0,1,3,6,10,15,21,28,36,45]

    >>> take 1 (scanl undefined 'a' undefined)
    "a"

scanl1 :: (a -> a -> a) -> [a] -> [a] #

\(\mathcal{O}(n)\). `scanl1` is a variant of `scanl` that has no starting value argument:

    scanl1 f [x1, x2, ...] == [x1, x1 `f` x2, ...]

#### Examples

    [1,3,6,10]

    [1,3,6,10,15,21,28,36,45,55]

    >>> take 1 (scanl1 undefined ('a' : undefined))
    "a"

scanr :: (a -> b -> b) -> b -> [a] -> [b] #

\(\mathcal{O}(n)\). `scanr` is the right-to-left dual of `scanl`. Note that the order of parameters on the accumulating function are reversed compared to `scanl`. Also note that

    head (scanr f z xs) == foldr f z xs.

#### Examples

iterate :: (a -> a) -> a -> [a] #

`iterate` `f x` returns an infinite list of repeated applications of `f` to `x`:

    iterate f x == [x, f x, f (f x), ...]

#### Laziness

Expand

Note that `iterate` is lazy, potentially leading to thunk build-up if the consumer doesn't force each iterate. See `iterate'` for a strict variant of this function.

    >>> take 1 $ iterate undefined 42
    [42]

#### Examples

Expand

    >>> take 10 $ iterate not True

    >>> take 10 $ iterate (+3) 42
    [42,45,48,51,54,57,60,63,66,69]

`splitAt` is an instance of the more general `genericSplitAt`, in which `n` may be of any integral type.

#### Laziness

Expand

It is equivalent to `(`take` n xs, `drop` n xs)` unless `n` is `_|_`: `splitAt _|_ xs = _|_`, not `(_|_, _|_)`).

The first component of the tuple is produced lazily:

    >>> fst (splitAt 0 undefined)
    []

    >>> take 1 (fst (splitAt 10 (1 : undefined)))
    [1]

#### Examples

Expand

    >>> splitAt 6 "Hello World!"

span :: (a -> Bool) -> [a] -> ([a], [a]) #

`span`, applied to a predicate `p` and a list `xs`, returns a tuple where first element is the longest prefix (possibly empty) of `xs` of elements that satisfy `p` and second element is the remainder of the list:

`span` `p xs` is equivalent to `(`takeWhile` p xs, `dropWhile` p xs)`, even if `p` is `_|_`.

`span` produces the first component of the tuple lazily:

    >>> take 10 (fst (span (const True) [1..]))
    [1,2,3,4,5,6,7,8,9,10]

#### Examples

Expand

    >>> span (< 3) [1,2,3,4,1,2,3,4]
    ([1,2],[3,4,1,2,3,4])

    >>> span (< 9) [1,2,3]

    >>> span (< 0) [1,2,3]
    ([],[1,2,3])

break :: (a -> Bool) -> [a] -> ([a], [a]) #

`break`, applied to a predicate `p` and a list `xs`, returns a tuple where first element is longest prefix (possibly empty) of `xs` of elements that do not satisfy `p` and second element is the remainder of the list:

`break` `p` is equivalent to ``span` (`not` . p)` and consequently to `(`takeWhile` (`not` . p) xs, `dropWhile` (`not` . p) xs)`, even if `p` is `_|_`.

#### Examples

concatMap :: Foldable t => (a -> [b]) -> t a -> [b] #

Map a function over all the elements of a container and concatenate the resulting lists.

#### Examples

Expand

Basic usage:

    >>> concatMap (take 3) [[1..], [10..], [100..], [1000..]]
    [1,2,3,10,11,12,100,101,102,1000,1001,1002]

    >>> concatMap (take 3) (Just [1..])
    [1,2,3]

(!!) :: HasCallStack => [a] -> Int -> a infixl 9 #

List index (subscript) operator, starting from 0. It is an instance of the more general `genericIndex`, which takes an index of any integral type.

WARNING: This function is partial, and should only be used if you are sure that the indexing will not fail. Otherwise, use `!?`.

WARNING: This function takes linear time in the index.

#### Examples

Expand

    >>> ['a', 'b', 'c'] !! 0
    'a'

    >>> ['a', 'b', 'c'] !! 2
    'c'

    >>> ['a', 'b', 'c'] !! 3
    *** Exception: Prelude.!!: index too large

    >>> ['a', 'b', 'c'] !! (-1)
    *** Exception: Prelude.!!: negative index

zip3 :: [a] -> [b] -> [c] -> [(a, b, c)] #

`zip3` takes three lists and returns a list of triples, analogous to `zip`. It is capable of list fusion, but it is restricted to its first list argument and its resulting list.

zipWith :: (a -> b -> c) -> [a] -> [b] -> [c] #

\(\mathcal{O}(\min(m,n))\). `zipWith` generalises `zip` by zipping with the function given as the first argument, instead of a tupling function.

    zipWith (,) xs ys == zip xs ys
    zipWith f [x1,x2,x3..] [y1,y2,y3..] == [f x1 y1, f x2 y2, f x3 y3..]

`zipWith` is right-lazy:

    >>> let f = undefined
    >>> zipWith f [] undefined
    []

`zipWith` is capable of list fusion, but it is restricted to its first list argument and its resulting list.

#### Examples

Expand

``zipWith` `(+)`` can be applied to two lists to produce the list of corresponding sums:

    >>> zipWith (+) [1, 2, 3] [4, 5, 6]
    [5,7,9]

    >>> zipWith (++) ["hello ", "foo"] ["world!", "bar"]
    ["hello world!","foobar"]

zipWith3 :: (a -> b -> c -> d) -> [a] -> [b] -> [c] -> [d] #

\(\mathcal{O}(\min(l,m,n))\). The `zipWith3` function takes a function which combines three elements, as well as three lists and returns a list of the function applied to corresponding elements, analogous to `zipWith`. It is capable of list fusion, but it is restricted to its first list argument and its resulting list.

    zipWith3 (,,) xs ys zs == zip3 xs ys zs
    zipWith3 f [x1,x2,x3..] [y1,y2,y3..] [z1,z2,z3..] == [f x1 y1 z1, f x2 y2 z2, f x3 y3 z3..]

#### Examples

Expand

    >>> zipWith3 (\x y z -> [x, y, z]) "123" "abc" "xyz"
    ["1ax","2by","3cz"]

    >>> zipWith3 (\x y z -> (x * y) + z) [1, 2, 3] [4, 5, 6] [7, 8, 9]
    [11,18,27]

unzip3 :: [(a, b, c)] -> ([a], [b], [c]) #

The `unzip3` function takes a list of triples and returns three lists of the respective components, analogous to `unzip`.

#### Examples

Expand

    >>> unzip3 []
    ([],[],[])

    >>> unzip3 [(1, 'a', True), (2, 'b', False)]
    ([1,2],"ab",[True,False])

type ShowS = String -> String #

The `shows` functions return a function that prepends the output `String` to an existing `String`. This allows constant-time concatenation of results using function composition.

shows :: Show a => a -> ShowS #

equivalent to `showsPrec` with a precedence of 0.

showChar :: Char -> ShowS #

utility function converting a `Char` to a show function that simply prepends the character unchanged.

showString :: String -> ShowS #

utility function converting a `String` to a show function that simply prepends the string unchanged.

showParen :: Bool -> ShowS -> ShowS #

utility function that surrounds the inner show function with parentheses when the `Bool` parameter is `True`.

odd :: Integral a => a -> Bool #

(^^) :: (Fractional a, Integral b) => a -> b -> a infixr 8 #

raise a number to an integral power

gcd :: Integral a => a -> a -> a #

``gcd` x y` is the non-negative factor of both `x` and `y` of which every common factor of `x` and `y` is also a factor; for example ``gcd` 4 2 = 2`, ``gcd` (-4) 6 = 2`, ``gcd` 0 4` = `4`. ``gcd` 0 0` = `0`. (That is, the common divisor that is "greatest" in the divisibility preordering.)

Note: Since for signed fixed-width integer types, ``abs` `minBound` < 0`, the result may be negative if one of the arguments is ``minBound`` (and necessarily is if the other is `0` or ``minBound``) for such types.

lcm :: Integral a => a -> a -> a #

``lcm` x y` is the smallest positive integer that both `x` and `y` divide.

fst :: (a, b) -> a #

Extract the first component of a pair.

snd :: (a, b) -> b #

Extract the second component of a pair.

curry :: ((a, b) -> c) -> a -> b -> c #

`curry` converts an uncurried function to a curried function.

#### Examples

Expand

    >>> curry fst 1 2
    1

type ReadS a = String -> [(a, String)] #

A parser for a type `a`, represented as a function that takes a `String` and returns a list of possible parses as `(a,`String`)` pairs.

Note that this kind of backtracking parser is very inefficient; reading a large structure may be quite slow (cf `ReadP`).

lex :: ReadS String #

The `lex` function reads a single lexeme from the input, discarding initial white space, and returning the characters that constitute the lexeme. If the input string contains only white space, `lex` returns a single successful `lexeme' consisting of the empty string. (Thus ``lex` "" = [("","")]`.) If there is no legal lexeme at the beginning of the input string, `lex` fails (i.e. returns `[]`).

This lexer is not completely faithful to the Haskell lexical syntax in the following respects:

- Qualified names are not handled properly
- Octal and hexadecimal numerics are not recognized as a single token
- Comments are not treated properly

readParen :: Bool -> ReadS a -> ReadS a #

``readParen` `True` p` parses what `p` parses, but surrounded with parentheses.

``readParen` `False` p` parses what `p` parses, but optionally surrounded with parentheses.

either :: (a -> c) -> (b -> c) -> Either a b -> c #

Case analysis for the `Either` type. If the value is ``Left` a`, apply the first function to `a`; if it is ``Right` b`, apply the second function to `b`.

#### Examples

Expand

We create two values of type ``Either` `String` `Int``, one using the `Left` constructor and another using the `Right` constructor. Then we apply "either" the `length` function (if we have a `String`) or the "times-two" function (if we have an `Int`):

    >>> let s = Left "foo" :: Either String Int
    >>> let n = Right 3 :: Either String Int
    >>> either length (*2) s
    3
    >>> either length (*2) n
    6

reads :: Read a => ReadS a #

equivalent to `readsPrec` with a precedence of 0.

read :: Read a => String -> a #

The `read` function reads input from a string, which must be completely consumed by the input process. `read` fails with an `error` if the parse is unsuccessful, and it is therefore discouraged from being used in real applications. Use `readMaybe` or `readEither` for safe alternatives.

    >>> read "123" :: Int
    123

    >>> read "hello" :: Int
    *** Exception: Prelude.read: no parse

lines :: String -> [String] #

Splits the argument into a list of lines stripped of their terminating `\n` characters. The `\n` terminator is optional in a final non-empty line of the argument string.

When the argument string is empty, or ends in a `\n` character, it can be recovered by passing the result of `lines` to the `unlines` function. Otherwise, `unlines` appends the missing terminating `\n`. This makes `unlines . lines` idempotent:

    (unlines . lines) . (unlines . lines) = (unlines . lines)

#### Examples

Expand

    >>> lines ""           -- empty input contains no lines
    []

    >>> lines "\n"         -- single empty line
    [""]

    >>> lines "one"        -- single unterminated line
    ["one"]

    >>> lines "one\n"      -- single non-empty line
    ["one"]

    >>> lines "one\n\n"    -- second line is empty
    ["one",""]

    >>> lines "one\ntwo"   -- second line is unterminated
    ["one","two"]

    >>> lines "one\ntwo\n" -- two non-empty lines
    ["one","two"]

unlines :: [String] -> String #

Appends a `\n` character to each input string, then concatenates the results. Equivalent to ``foldMap` (s -> s `++` "\n")`.

#### Examples

Expand

    >>> unlines ["Hello", "World", "!"]
    "Hello\nWorld\n!\n"

Note that ``unlines` `.` `lines` `/=` `id`` when the input is not `\n`-terminated:

    >>> unlines . lines $ "foo\nbar"
    "foo\nbar\n"

words :: String -> [String] #

`words` breaks a string up into a list of words, which were delimited by white space (as defined by `isSpace`). This function trims any white spaces at the beginning and at the end.

#### Examples

Expand

    >>> words "Lorem ipsum\ndolor"
    ["Lorem","ipsum","dolor"]

    >>> words " foo bar "
    ["foo","bar"]

unwords :: [String] -> String #

`unwords` joins words with separating spaces (U+0020 SPACE).

`unwords` is neither left nor right inverse of `words`:

    >>> words (unwords [" "])
    []
    >>> unwords (words "foo\nbar")
    "foo bar"

#### Examples

Expand

    >>> unwords ["Lorem", "ipsum", "dolor"]
    "Lorem ipsum dolor"

    >>> unwords ["foo", "bar", "", "baz"]
    "foo bar  baz"

userError :: String -> IOError #

Construct an `IOError` value with a string describing the error. The `fail` method of the `IO` instance of the `Monad` class raises a `userError`, thus:

    instance Monad IO where
      ...
      fail s = ioError (userError s)

type FilePath = String #

File and directory names are values of type `String`, whose precise meaning is operating system dependent. Files can be opened, yielding a handle which can then be used to operate on the contents of that file.

ioError :: IOError -> IO a #

Raise an `IOError` in the `IO` monad.

putChar :: Char -> IO () #

Write a character to the standard output device (same as `hPutChar` `stdout`).

putStr :: String -> IO () #

Write a string to the standard output device (same as `hPutStr` `stdout`).

getChar :: IO Char #

Read a character from the standard input device (same as `hGetChar` `stdin`).

getContents :: IO String #

The `getContents` operation returns all user input as a single string, which is read lazily as it is needed (same as `hGetContents` `stdin`).

interact :: (String -> String) -> IO () #

The `interact` function takes a function of type `String->String` as its argument. The entire input from the standard input device is passed to this function as its argument, and the resulting string is output on the standard output device.

readFile :: FilePath -> IO String #

The `readFile` function reads a file and returns the contents of the file as a string. The file is read lazily, on demand, as with `getContents`.

appendFile :: FilePath -> String -> IO () #

The computation `appendFile` `file str` function appends the string `str`, to the file `file`.

Note that `writeFile` and `appendFile` write a literal string to a file. To write a value of any printable type, as with `print`, use the `show` function to convert the value to a string first.

    main = appendFile "squares" (show [(x,x*x) | x <- [0,0.1..2]])

readLn :: Read a => IO a #

The `readLn` function combines `getLine` and `readIO`.

readIO :: Read a => String -> IO a #

The `readIO` function is similar to `read` except that it signals parse failure to the `IO` monad instead of terminating the program.

# Core

These are the building blocks on which the config language is built. Regular people shouldn't need to know about these.

type Prime (l :: Type -> Type) (l' :: Type -> Type) = Arr (XConfig l) (XConfig l') #

A Prime is a function that transforms an XConfig. It's not a monad, but we turn on RebindableSyntax so we can abuse the pretty do notation.

type Arr x y = x -> IO y #

An Arr is a generalization of Prime. Don't reference the type, if you can avoid it. It might go away in the future.

(>>) :: Arr x y -> Arr y z -> Arr x z #

Composes two Arrs using `>>=` from Prelude.

ifThenElse :: Bool -> a -> a -> a #

Because of RebindableSyntax, this is necessary to enable you to use if-then-else expressions. No need to call it directly.

# Example config

As an example, I've included below a subset of my current config. Note that my import statements specify individual identifiers in parentheticals. That's optional. The default is to import the entire module. I just find it helpful to remind me where things came from.

    {-# LANGUAGE RebindableSyntax #-}
    import XMonad.Config.Prime

    import XMonad.Actions.CycleWS (prevWS, nextWS)
    import XMonad.Actions.SwapWorkspaces (swapWithCurrent)
    import XMonad.Actions.WindowNavigation (withWindowNavigation)
    import XMonad.Layout.Fullscreen (fullscreenSupport)
    import XMonad.Layout.NoBorders (smartBorders)
    import XMonad.Layout.Tabbed (simpleTabbed)

    main = xmonad $ do
      modMask =: mod4Mask
      normalBorderColor =: "#222222"
      terminal =: "urxvt"
      focusFollowsMouse =: False
      resetLayout $ Tall 1 (3/100) (1/2) ||| simpleTabbed
      modifyLayout smartBorders
      apply fullscreenSupport
      applyIO $ withWindowNavigation (xK_w, xK_a, xK_s, xK_d)
      withWorkspaces $ do
        wsKeys =+ ["0"]
        wsActions =+ [("M-M1-", windows . swapWithCurrent)]
      keys =+ [
          ("M-,",                      sendMessage $ IncMasterN (-1)),
          ("M-.",                      sendMessage $ IncMasterN 1),
          ("M-M1-d",                   spawn "date | dzen2 -fg '#eeeeee' -p 2"),
          ("C-S-q",                    return ()),
          ("<XF86AudioLowerVolume>",   spawn "amixer set Master 5%-"),
          ("<XF86AudioRaiseVolume>",   spawn "amixer set Master 5%+"),
          ("M-M1-x",                   kill),
          ("M-i",                      prevWS),
          ("M-o",                      nextWS)
        ]

# Troubleshooting

### Only the last line of my config seems to take effect. What gives?

You're missing the `{-# LANGUAGE RebindableSyntax #-}` line at the top.

### How do I do use normal monads like `X` or `IO`?

Here are a couple of ways:

    import qualified Prelude as P
    ...
    test1, test2 :: X ()
    test1 = spawn "echo Hi" P.>> spawn "echo Bye"
    test2 = do spawn "echo Hi"
               spawn "echo Bye"
      where (>>) = (P.>>)

### How do I use the old keyboard syntax?

You can use `apply` and supply your own Haskell function. For instance:

    apply $ flip additionalKeys $ [((mod1Mask, xK_z), spawn "date | dzen2 -fg '#eeeeee' -p 2")]

### How do I run a command before xmonad starts (like `spawnPipe`)?

If you're using it for a status bar, see if `dzen` or `xmobar` does what you want. If so, you can apply it with `applyIO`.

If not, you can write your own `XConfig l -> IO (XConfig l)` and apply it with `applyIO`. When writing this function, see the above tip about using normal monads.

Alternatively, you could do something like this this:

    import qualified Prelude as P (>>)

    main =
      openFile ".xmonad.log" AppendMode >>= \log ->
      hSetBuffering log LineBuffering P.>>
      (xmonad $ do
         nothing -- Prime config here.
      )
