2007-05-25Deleting a window should not affect focusRob
This fixes a bug whereby deleting a window will first move focus to that window before deleting it without moving focus back afterwards. The fix generalises the remove inner function to delete a window from the stack whether it's in focus or not. If the window is in focus, behaviour remains as it was. darcs-hash:20070525024118-64d90-a9f70b49186be59e62af4b11671099996c5e294f

2007-05-20HEADS UP: Rewrite StackSet as a ZipperDon Stewart
In order to give a better account of how focus and master interact, and how each operation affects focus, we reimplement the StackSet type as a two level nested 'Zipper'. To quote Oleg: A Zipper is essentially an `updateable' and yet pure functional cursor into a data structure. Zipper is also a delimited continuation reified as a data structure. That is, we use the Zipper as a cursor which encodes the window which is in focus. Thus our data structure tracks focus correctly by construction! We then get simple, obvious semantics for e.g. insert, in terms of how it affects focus/master. Our transient-messes-with-focus bug evaporates. 'swap' becomes trivial. By moving focus directly into the stackset, we can toss some QC properties about focus handling: it is simply impossible now for focus to go wrong. As a benefit, we get a dozen new QC properties for free, governing how master and focus operate. The encoding of focus in the data type also simplifies the focus handling in Operations: several operations affecting focus are now simply wrappers over StackSet. For the full story, please read the StackSet module, and the QC properties. Finally, we save ~40 lines with the simplified logic in Operations.hs For more info, see the blog post on the implementation, http://cgi.cse.unsw.edu.au/~dons/blog/2007/05/17#xmonad_part1b_zipper darcs-hash:20070520070053-9c5c1-241f7ee7793f5db2b9e33d375965cdc21b26cbd7

2007-04-19Promote now swaps focused window with master windowDon Stewart
This means other windows are unaffected. The change from the previous cycling behaviour was felt necessary, since cycling isn't a terribly useful operation. Some properties that hold: focus is unchanged by promotion promote is idempotent (promoting twice does nothing) the focused and master window will swap their positions in the stack darcs-hash:20070418224236-9c5c1-4539f9f397e181f91dc9743e3ffac4b5796c0fac

2007-04-11Change semantics of 'promote'.Don Stewart
Previously 'promote' would move the currently focused window into the master position in tiled mode. This was *almost* a cycle of the windows, but not quite (depending on where the focus was, it was in fact a cycle). Now we do the obvious generalisation, and just cycle the current window stack. Simpler to understand, simpler to reason about. darcs-hash:20070411073456-9c5c1-3ee88f9ac46e2301b4c803ec4fd66798e6fee91d
