* HEADS UP: Rewrite StackSet as a ZipperDon Stewart2007-05-201-194/+162
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.gz

* Constrain layout messages to be members of a Message classDon Stewart2007-05-041-20/+24
| | | | | | | | | | | | | | | | | | Using Typeables as the only constraint on layout messages is a bit scary, as a user can send arbitrary values to layoutMsg, whether they make sense or not: there's basically no type feedback on the values you supply to layoutMsg. Folloing Simon Marlow's dynamically extensible exceptions paper, we use an existential type, and a Message type class, to constrain valid arguments to layoutMsg to be valid members of Message. That is, a user writes some data type for messages their layout algorithm accepts: data MyLayoutEvent darcs-hash:20070504081649-9c5c1-954b406e8c21c2ca4428960e4fc1f9ffb17fb296.gz

* Change semantics of 'promote'.Don Stewart2007-04-111-7/+3
| | | | | | | | | | | | 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.gz
