A Sinatra-based webapp that retrieves the content of a gist and generates the PlantUML image URL from it. Apparently, I'm a Ruby beginner. Please feel free to fork and make it better.

trustin / hintstyle.patch
Created November 1, 2013 18:10
Wine patch for saner font hinting configuration, which applies 'hintslight' for ASCII glyphs and 'hintnone' for others such as CJK glyphs. I hope Wine uses fontconfig to respect the hintstyle, lcdfilter, and rgba properties like other GTK apps do.
