At some point `peekCString` became locale aware. This is a double
bug, since (a) `decodeString` was being applied to the result and
(b) the locale might not be UTF-8, but the string being decoded
always is.
The fix is to use `peekCAString` which bypasses the locale decode,
then continuing to do UTF-8 decode.
I have no idea what I was thinking when I wrote that code.
While at it, just reused the code for ICCCM title which already
assumes the client may have broken the rules (I think we have
seen a case of `WM_NAME` being `UTF8_STRING`).
Whenever possible, prefer the safe wrappers withWindowAttributes or
safeGetWindowAttributes to getWindowAttributes.
Places where these are not applicable are limited to layouts, where
there is not good "default value" to give back in case these calls fail.
In these cases, we let the exception handling of the layout mechanism
handle it and fall back to the Full layout.
Fixes: https://github.com/xmonad/xmonad-contrib/issues/146
Move the function from X.U.DebugWindow, where it was defined already.
This is a safe version of getWindowAttributes, returning a Maybe instead
of throwing an exception, in case the window attributes could not be
retrieved.
This is a convenience module in order to have less import noise. It
re-exports the following:
a) Commonly used modules in full (Data.Foldable, Data.Applicative, and
so on); though only those that play nicely with each other, so that
XMonad.Prelude can be imported unqualified without any problems.
This prevents things like `Prelude.(.)` and `Control.Category.(.)`
fighting with each other.
b) Helper functions that don't necessarily fit in any other module;
e.g., the often used abbreviation `fi = fromIntegral`.
Various fixes and enhancements to DebugWindow and DebugStack. ManageDebug
requires these fixes, but some of them are significant even if not using
ManageDebug.
The warnings were related to ghc-7.6 removing Prelude.catch
(triggering warnings regarding the import hiding it), as well
as defaulting of some numeric types.
