-Piggy-back on the haskell-ci workflow for automatic releases to Hackage.
-
-This extends the workflow with two additional triggers:
-
- * When a release is created on GitHub, a candidate release is uploaded to
-   Hackage and docs are submitted for it as Hackage can't build them itself
-   (https://github.com/haskell/hackage-server/issues/925).
-
- * To make a final release, the workflow can be triggered manually by entering
-   the correct version number matching the version in the cabal file. This is
-   here because promoting the candidate on Hackage discards the uploaded docs
-   (https://github.com/haskell/hackage-server/issues/70).
-
-The automation uses a special Hackage user: https://hackage.haskell.org/user/xmonad
-and each repo (X11, xmonad, xmonad-contrib) has its own HACKAGE_API_KEY token
-set in GitHub repository secrets.

-# xmonad-contrib
+You need the ghc compiler and xmonad window manager installed in
+order to use these extensions.
 
-**Community-maintained extensions for the [XMonad][web:xmonad] window manager.**
+For installation and configuration instructions, please see the
+[xmonad website] [xmonad], the documents included with the
+[xmonad source distribution] [xmonad-git], and the
+[online haddock documentation] [xmonad-docs].
 
-[xmonad core][gh:xmonad] is minimal, stable, yet extensible.
+## Getting or Updating XMonadContrib
-[xmonad-contrib][gh:xmonad-contrib] is home to hundreds of additional tiling
-algorithms and extension modules. The two combined make for a powerful X11
-window-manager with endless customization possibilities. They are, quite
-literally, libraries for creating your own window manager.
 
-## Installation
+  * Latest release: <https://hackage.haskell.org/package/xmonad-contrib>
 
-For installation and configuration instructions, please see:
+  * Git version: <https://github.com/xmonad/xmonad-contrib>
 
- * [downloading and installing xmonad][web:download]
+(To use git xmonad-contrib you must also use the
- * [installing latest xmonad snapshot from git][web:install]
+[git version of xmonad] [xmonad-git].)
- * [configuring xmonad][web:tutorial]
-
-If you run into any trouble, consult our [documentation][web:documentation] or
-ask the [community][web:community] for help.
 
 ## Contributing
 
-We welcome all forms of contributions:
+Haskell code contributed to this repo should live under the
+appropriate subdivision of the `XMonad` namespace (currently includes
+`Actions`, `Config`, `Hooks`, `Layout`, `Prompt`, and `Util`). For
+example, to use the Grid layout, one would import:
 
- * [bug reports and feature ideas][gh:xmonad-contrib:issues]
+    XMonad.Layout.Grid
-   (also to [xmonad][gh:xmonad:issues])
- * [bug fixes, new features, new extensions][gh:xmonad-contrib:pulls]
-   (also to [xmonad][gh:xmonad:pulls])
- * documentation fixes and improvements: [xmonad][gh:xmonad],
-   [xmonad-contrib][gh:xmonad-contrib], [xmonad-web][gh:xmonad-web]
- * helping others in the [community][web:community]
- * financial support: [GitHub Sponsors][gh:xmonad:sponsors],
-   [Open Collective][opencollective:xmonad]

--- $usage
---
--- You can use this module's basic functionality with the following in your
--- @~\/.xmonad\/xmonad.hs@:
---
--- >    import XMonad.Actions.EasyMotion (selectWindow)
---
--- To customise
---
--- >    import XMonad.Actions.EasyMotion (selectWindow, EasyMotionConfig(..))
---
--- Then add a keybinding and an action to the 'selectWindow' function.
--- In this case @M-f@ to focus the selected window:
---
--- >    , ((modm, xK_f), selectWindow def >>= (`whenJust` windows . W.focusWindow))
---
--- Similarly, to kill a window with @M-f@:
---
--- >    , ((modm, xK_f), selectWindow def >>= (`whenJust` killWindow))
---
--- See 'EasyMotionConfig' for all configuration options. A short summary follows.
---
--- Default chord keys are @s,d,f,j,k,l@. To customise these and display options assign
--- different values to 'def' (the default configuration):
---
--- >    , ((modm, xK_f), (selectWindow def{sKeys = AnyKeys [xK_f, xK_d]}) >>= (`whenJust` windows . W.focusWindow))
---
--- You must supply at least two different keys in the 'sKeys' list. Keys provided earlier in the list
--- will be used preferentially—therefore, keys you would like to use more frequently should be
--- earlier in the list.
---
--- To map different sets of keys to different screens. The following configuration maps keys @fdsa@
--- to screen 0 and @hjkl@ to screen 1. Keys provided earlier in the list will be used preferentially.
--- Providing the same key for multiple screens is possible but will break down in some scenarios.
---
--- >    import qualified Data.Map.Strict as StrictMap (fromList)
--- >    emConf :: EasyMotionConfig
--- >    emConf = def { sKeys = PerScreenKeys $ StrictMap.fromList [(0, [xK_f, xK_d, xK_s, xK_a]), (1, [xK_h, xK_j, xK_k, xK_l])] }
--- >    -- key bindings
--- >    , ((modm, xK_f), selectWindow emConf >>= (`whenJust` windows . W.focusWindow))
---
--- To customise the font:
---
--- >    , ((modm, xK_f), (selectWindow def{emFont = "xft: Sans-40"}) >>= (`whenJust` windows . W.focusWindow))
---
--- The 'emFont' field provided is supplied directly to the 'initXMF' function. The default is
--- @"xft:Sans-100"@. Some example options:
---
--- >    "xft: Sans-40"
--- >    "xft: Arial-100"
--- >    "xft: Cambria-80"
---
--- Customise the overlay by supplying a function to 'overlayF'. The signature is
--- @'Position' -> 'Rectangle' -> 'Rectangle'@. The parameters are the height in pixels of
--- the selection chord and the rectangle of the window to be overlaid. Some are provided:
---
--- >    import XMonad.Actions.EasyMotion (selectWindow, EasyMotionConfig(..), proportional, bar, fullSize)
--- >    , ((modm, xK_f), (selectWindow def{ overlayF = proportional 0.3  }) >>= (`whenJust` windows . W.focusWindow))
--- >    , ((modm, xK_f), (selectWindow def{ overlayF = bar 0.5           }) >>= (`whenJust` windows . W.focusWindow))
--- >    , ((modm, xK_f), (selectWindow def{ overlayF = fullSize          }) >>= (`whenJust` windows . W.focusWindow))
--- >    , ((modm, xK_f), (selectWindow def{ overlayF = fixedSize 300 350 }) >>= (`whenJust` windows . W.focusWindow))
-
--- TODO:
---  - An overlay function that creates an overlay a proportion of the width XOR height of the
---    window it's over, and with a fixed w/h proportion? E.g. overlay-height = 0.3 *
---    target-window-height; overlay-width = 0.5 * overlay-height.
---  - An overlay function that creates an overlay of a fixed w,h, aligned mid,mid, or parametrised
---    alignment?
---  - Parametrise chord generation?
---  - W.shift example; bring window from other screen to current screen? Only useful if we don't
---    show chords on current workspace.
---  - Use stringToKeysym, keysymToKeycode, keycodeToKeysym, keysymToString to take a string from
---    the user?
---  - Think a bit more about improving functionality with floating windows.
---    - currently, floating window z-order is not respected
---    - could ignore floating windows
---    - may be able to calculate the visible section of a floating window, and display the chord in
---      that space
---  - Provide an option to prepend the screen key to the easymotion keys (i.e. w,e,r)?
---  - overlay alpha
---  - Delay after selection so the user can see what they've chosen? Min-delay: 0 seconds. If
---    there's a delay, perhaps keep the other windows covered briefly to naturally draw the user's
---    attention to the window they've selected? Or briefly highlight the border of the selected
---    window?
---  - Option to cover windows that will not be selected by the current chord, such that it's
---    slightly more obvious where to maintain focus.
---  - Something unpleasant happens when the user provides only two keys (let's say f, d) for
---    chords. When they have five windows open, the following chords are generated: ddd, ddf, dfd,
---    dff, fdd. When 'f' is pressed, all chords disappear unexpectedly because we know there are no
---    other valid options. The user expects to press 'fdd'. This is an optimisation in software but
---    pretty bad for usability, as the user continues firing keys into their
---    now-unexpectedly-active window. And is of course only one concrete example of a more general
---    problem.
---    Short-term solution:
---      - Keep displaying the chord until the user has fully entered it
---    Fix:
---      - Show the shortest possible chords
-

-{- $usage
-
-This module implements Emacs-style prefix argument.  The argument
-comes in two flavours, "Raw" and "Numeric".
-
-To initiate the "prefix mode" you hit the prefix keybinding (default
-C-u).  This sets the Raw argument value to 1.  Repeatedly hitting this
-key increments the raw value by 1.  The Raw argument is usually used
-as a toggle, changing the behaviour of the function called in some way.
-
-An example might be calling "mpc add" to add new song to the playlist,
-but with C-u we also clean up the playlist beforehand.
-
-When in the "Raw mode", you can hit numeric keys 0..9 (with no
-modifier) to enter a "Numeric argument".  Numeric argument represents
-a natural number.  Hitting numeric keys in sequence produces the
-decimal number that would result from typing them.  That is, the
-sequence C-u 4 2 sets the Numeric argument value to the number 42.
-
-If you have a function which understands the prefix argument, for example:
-
->    addMaybeClean :: PrefixArgument -> X ()
->    addMaybeClean (Raw _) = spawn "mpc clear" >> spawn "mpc add <file>"
->    addMaybeClean _ = spawn "mpc add <file>"
-
-you can turn it into an X action with the function 'withPrefixArgument'.
-
-Binding it in your config
-
->    ((modm, xK_a), withPrefixArgument addMaybeClean)
-
-Hitting MOD-a will add the <file> to the playlist while C-u MOD-a will
-clear the playlist and then add the file.
-
-You can of course use an anonymous action, like so:
-
->    ((modm, xK_a), withPrefixArgument $ \prefix -> do
->        case prefix of ...
->    )
-
-If the prefix key is followed by a binding which is unknown to XMonad,
-the prefix along with that binding is sent to the active window.
-
-There is one caveat: when you use an application which has a nested
-C-u binding, for example C-c C-u in Emacs org-mode, you have to hit
-C-g (or any other non-recognized key really) to get out of the "xmonad
-grab" and let the C-c C-u be sent to the application.
-
--}
-
-{- $installation
-
-The simplest way to enable this is to use 'useDefaultPrefixArgument'
-
->    xmonad $ useDefaultPrefixArgument $ def { .. }
-
-The default prefix argument is C-u.  If you want to customize the
-prefix argument, 'usePrefixArgument' can be used:
-
->    xmonad $ usePrefixArgument "M-u" $ def { .. }
-
-where the key is entered in Emacs style (or "XMonad.Util.EZConfig"
-style) notation.  The letter `M` stands for your chosen modifier.  The
-function defaults to C-u if the argument could not be parsed.

-You can use this module with the following in your @~\/.xmonad\/xmonad.hs@:
-
-> import XMonad.Actions.RotateSome
-
-and add keybindings such as the following:
-
->   , ((modMask .|. controlMask, xK_n), surfaceNext)
->   , ((modMask .|. controlMask, xK_p), surfacePrev)
-
--}
-
-{- $example
-#Example#
-
-Consider a workspace whose stack contains five windows A B C D E but whose
-layout limits how many will actually be shown, showing only the first plus
-two additional windows, starting with the third:
-
->  ┌─────┬─────┐
->  │     │  C  │
->  │  A  ├─────┤
->  │     │  D  │
->  └─────┴─────┘
->
->  A  B  C  D  E
->  _     ____
-
-If C has focus and we'd like to replace it with one of the unshown windows,
-'surfaceNext' will move the next unshown window, E, into the focused position:
-
->  ┌─────┬─────┐                ┌─────┬─────┐
->  │     │ *C* │                │     │ *E* │
->  │  A  ├─────┤ surfaceNext -> │  A  ├─────┤
->  │     │  D  │                │     │  D  │
->  └─────┴─────┘                └─────┴─────┘
->
->  A  B *C* D  E                A  C *E* D  B
->  _     ____                   _     ____
-
-This repositioned windows B C E by treating them as a sequence that can be
-rotated through the focused stack position. Windows A and D remain anchored
-to their original (visible) positions.
-
-A second call to 'surfaceNext' moves B into focus:
-
->  ┌─────┬─────┐                ┌─────┬─────┐
->  │     │ *E* │                │     │ *B* │
->  │  A  ├─────┤ surfaceNext -> │  A  ├─────┤
->  │     │  D  │                │     │  D  │
->  └─────┴─────┘                └─────┴─────┘

--- $usage
--- Given your configuration file, import this module:
---
--- > import XMonad.Actions.SwapPromote
---
--- First add 'masterHistoryHook' to your 'logHook' to track master windows per
--- workspace:
---
--- > myLogHook = otherHook >> masterHistoryHook
---
--- Then replace xmonad's default promote keybinding with 'swapPromote'':
---
--- > , ((mod1Mask, xK_Return), swapPromote' False)
---
--- Depending on your xmonad configuration or window actions the master history
--- may be empty. If this is the case you can still chain another promotion
--- function:
---
--- > import XMonad.Actions.DwmPromote
--- > , ((mod1Mask, xK_Return), whenX (swapPromote False) dwmpromote)
---
--- To be clear, this is only called when the lack of master history hindered
--- the swap and not other conditions, such as having a only a single window.
---
--- While 'swapPromote' preserves window focus, 'swapIn' preserves the focus
--- position - effectively "swapping" new windows into focus without moving the
--- zipper. A mix of both, 'swapHybrid' promotes focused non-master windows
--- while swapping windows into the focused master. This works well on layouts
--- with large masters. Both come with chainable variants, see 'swapIn'' and
--- 'swapHybrid''.
---
--- So far floating windows have been treated no differently than tiled windows
--- even though their positions are independent of the stack. Often, yanking
--- floating windows in and out of the workspace will obliterate the stack
--- history - particularly frustrating with 'XMonad.Util.Scratchpad' since it is
--- toggled so frequenty and always replaces the master window. That's why the
--- swap functions accept a boolean argument; when @True@ non-focused floating
--- windows will be ignored.
---
--- All together:

---     "XMonad.Hooks.WorkspaceHistory" for further details
---
--- Let us go through a full example together.
---
--- A 'TopicItem' consists of three things: the name of the topic, its
--- root directory, and the action associated to it—to be executed if the
--- topic is empty or the action is forced via a keybinding.
---
--- We start by specifying our chosen topics as a list of such
--- 'TopicItem's:
---
--- > topicItems :: [TopicItem]
--- > topicItems =
--- >   [ inHome   "1:WEB"              (spawn "firefox")
--- >   , noAction "2"      "."
--- >   , noAction "3:VID"  "videos"
--- >   , TI       "4:VPN"  "openvpn"   (spawn "urxvt -e randomVPN.sh")
--- >   , inHome   "5:IM"               (spawn "signal" *> spawn "telegram")
--- >   , inHome   "6:IRC"              (spawn "urxvt -e weechat")
--- >   , TI       "dts"    ".dotfiles" spawnShell
--- >   , TI       "xm-con" "hs/xm-con" (spawnShell *> spawnShellIn "hs/xm")
 -- >   ]
---
+-- >
--- Then we just need to put together our topic config:
---
 -- > myTopicConfig :: TopicConfig
 -- > myTopicConfig = def
--- >   { topicDirs          = tiDirs    topicItems
+-- >   { topicDirs = M.fromList $

---
--- Hopefully you've gotten a general feeling of how to define these kind of
--- small helper functions using what's provided in this module.
---
--- Adding the appropriate keybindings works as it normally would.  Here,
--- we'll use "XMonad.Util.EZConfig" syntax:
---
--- > myKeys :: [(String, X ())]
--- > myKeys =
--- >   [ ("M-n"        , spawnShell)
--- >   , ("M-a"        , currentTopicAction myTopicConfig)
--- >   , ("M-g"        , promptedGoto)
--- >   , ("M-S-g"      , promptedShift)
--- >   , ("M-S-<Space>", toggleTopic)
--- >   ]
--- >   ++
--- >   -- The following does two things:
--- >   --   1. Switch topics (no modifier)
--- >   --   2. Move focused window to topic N (shift modifier)
--- >   [ ("M-" ++ m ++ k, f i)
--- >   | (i, k) <- zip (topicNames topicItems) (map show [1 .. 9 :: Int])
--- >   , (f, m) <- [(goto, ""), (windows . W.shift, "S-")]
--- >   ]
---
--- This makes @M-1@ to @M-9@ switch to the first nine topics that we
--- have specified in @topicItems@.
---
--- You can also switch to the nine last-used topics instead:
---
--- >   [ ("M-" ++ show i, switchNthLastFocused myTopicConfig i)
--- >   | i <- [1 .. 9]
--- >   ]
---
--- We can now put the whole configuration together with the following:
---
 -- > main :: IO ()
--- > main = xmonad $ def
+-- > main = xmonad =<< myConfig
--- >   { workspaces = topicNames topicItems
--- >   }
--- >  `additionalKeysP` myKeys
