The way of icon path lookup for `menubar` is enhanced so that it is based on a theme-oriented way as described in the specification: Icon Theme Specification, Ver. 0.12 http://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html To accomplish this: * Add the two new files `icon_theme.lua` and `index_theme.lua`. The former implements an icon lookup algorithm suggested in the URL above. The latter implements a helper object to parse the cache file `index.theme` of which data is used by the former. * Modify `menu_gen.lua` to use the new algorithm. - The implementation of `lookup_category_icons` is changed accordingly. - The values of the field `all_categories.icon_name` are changed file names to icon names, i.e., file extensions which are used to indicate image file formats are removed. * Add the new file `icon_theme_spec.lua` for a unit test for checking if `icon_theme.lua` together with `index_theme.lua` works as expected. |
