* HEADS UP: Rewrite StackSet as a ZipperDon Stewart2007-05-207-757/+1107
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Arbitrary instance for StackSet must set random focus on each workspaceDon Stewart2007-05-081-7/+33
| | | | | | | | | | | | | | | | | | When focus was separated from the stack order on each workspace, we forgot to update the Arbitrary instance to set random focus. As spotted by David R, this then invalidates 4 of our QC properties. In particular, the property involving where focus goes after a random transient (annoying behaviour) appeared to be correct, but wasn't, due to inadequate coverage. This patch sets focus to a random window on each workspace. As a result, we now catch the focus/raise/delete issue people have been complaining about. Lesson: make sure your QuickCheck generators are doing what you think they are. darcs-hash:20070508051126-9c5c1-55a0597e6838b35f12b3d348e85360cda6c237ca.gz

* Constrain layout messages to be members of a Message classDon Stewart2007-05-043-32/+54
| | | | | | | | | | | | | | | | | | 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
