A set of hooks, and convenience combinators, to help with ManageHook debugging.
Ordinary users may well want to use debugManageHookOn in normal configs,
specifying a key sequence which can be pressed before running a command in
order to capture debug information just for that command's main window.
This is especially useful when trying to diagnose issues such as programs
that do not play well with SpawnOn, or ManageHook matching on 'title' when
the program does not set the window title until after it is mapped.
Various fixes and enhancements to DebugWindow and DebugStack. ManageDebug
requires these fixes, but some of them are significant even if not using
ManageDebug.
The following change from 2013-02-09 breaks shell completion for me:
hunk ./XMonad/Prompt/Shell.hs 65
+ commandToComplete _ c = c
It seems to be passing the entire string into compgen in order to get the file completions, but it should only pass the last word. I propose reverting this change. Comments are appreciated.
This makes a breakage due to missing patches in core a bit more obvious.
Previously you would have a build failure regarding some missing identifiers
(def re-exported by XMonad from Data.Default), while after applying this patch
it will be clear that xmonad-core needs to be updated.
The issue was that window titles, such as those set by, for example a browser,
could set the window title to display something like
<action=malicious shell command>normal title</action>
Which could be executed by xmobar (or dzen).
This adds a ppTitleSanitize which does the above functions. This way when users
override ppTitle, the benefits are not lost.
Thanks to Raúl Benencia and Joachim Breitner for bringing this to my attention.
Hooks.DynamicBars was previously using an MVar and the unsafePerformIO hack (
http://www.haskell.org/haskellwiki/Top_level_mutable_state ) to store bar
state. Since ExtensibleState exists to solve these sorts of problems, I've
switched the file over to use unsafePerformIO instead.
Some functions' types had to be changed to allow access to XState, but the
public API is unchanged.
