</h1><div class="doc"><p>The <code><a href="XMonad-StackSet.html#t:StackSet">StackSet</a></code> data type encodes a window manager abstraction. The
 window manager is a set of virtual workspaces. On each workspace is a
 stack of windows. A given workspace is always current, and a given
 window on each workspace has focus. The focused window on the current
 workspace is the one which will take user input. It can be visualised
 as follows:
</p><pre> Workspace  { 0*}   { 1 }   { 2 }   { 3 }   { 4 }

 Windows    [1      []      [3*     [6*]    []
            ,2*]            ,4
                            ,5]
</pre><p>Note that workspaces are indexed from 0, windows are numbered
 uniquely. A <code><a href="/usr/share/doc/ghc-doc/html/libraries/base-4.6.0.1/Prelude.html#v:-42-">*</a></code> indicates the window on each workspace that has
 focus, and which workspace is current.
</p></div><h2 id="g:2">The Zipper
</h2><div class="doc"><p>We encode all the focus tracking directly in the data structure, with a <code>zipper</code>:
</p><p>A Zipper is essentially an <code>updateable</code> and yet pure functional
    cursor into a data structure. Zipper is also a delimited
    continuation reified as a data structure.
</p><p>The Zipper lets us replace an item deep in a complex data
    structure, e.g., a tree or a term, without an  mutation.  The
    resulting data structure will share as much of its components with
    the old structure as possible.
</p><p>Oleg Kiselyov, 27 Apr 2005, haskell@, <a href="Zipper as a delimited continuation.html">Zipper as a delimited continuation</a>
</p><p>We use the zipper to keep track of the focused workspace and the
 focused window on each workspace, allowing us to have correct focus
 by construction. We closely follow Huet's original implementation:
</p><p>G. Huet, <em>Functional Pearl: The Zipper</em>,
      1997, J. Functional Programming 75(5):549-554.
 and:

</h2><div class="doc"><p>Xinerama in X11 lets us view multiple virtual workspaces
 simultaneously. While only one will ever be in focus (i.e. will
 receive keyboard events), other workspaces may be passively
 viewable.  We thus need to track which virtual workspaces are
 associated (viewed) on which physical screens.  To keep track of
 this, <code><a href="XMonad-StackSet.html#t:StackSet">StackSet</a></code> keeps separate lists of visible but non-focused
 workspaces, and non-visible workspaces.
</p></div><h2 id="g:4">Master and Focus
</h2><div class="doc"><p>Each stack tracks a focused item, and for tiling purposes also tracks
 a <code>master</code> position. The connection between <code>master</code> and <code><a href="XMonad-StackSet.html#v:focus">focus</a></code>
 needs to be well defined, particularly in relation to <code>insert</code> and
 <code><a href="XMonad-StackSet.html#v:delete">delete</a></code>.

</p><p>We puncture the workspace list, producing a hole in the structure
 used to track the currently focused workspace. The two other lists
 that are produced are used to track those workspaces visible as
 Xinerama screens, and those workspaces not visible anywhere.

 Focus stays with the item moved.
