First, I finally went back and added support for clang in my whole-program-llvm wrapper. Usage is easy: just set
LLVM_COMPILER=clang and it should Just Work. In the process of implementing this clang support I ended up feeling pretty bad about some of the old code. I ended up refactoring out quite a bit and it is definitely cleaner now. I’m still not sold on this whole “object-oriented programming” thing, but it worked tolerably for a small chunk of Python code. The resulting objects are, of course, completely arbitrary bundles of functionality.
I also fixed a bug in taffybar that prevented non-ASCII window titles in xmonad from rendering properly in the XMonadLog widget. It turns out that xmonad lies about the types of strings it gets from X. While the type signature claims that they are
Strings (lists of
Char), they are actually lists of bytes stuffed into
Char. That is, the underlying utf-8 string was not decoded before being converted into a
String. A simple call to
decodeString from the utf8-string library fixed the issue.
