Instead of requiring sassc to be installed add meson subprojects which build libsass and sassc (currently both forks of mine, tested under linux/mingw/msvc) when needed. This allows us to drop the generated .css files and build scripts from git. See #1502

Summary
|
|
-------
|
|
|
|
* To be able to use the latest/adequate version of sass, install sassc
|
|
* meson will regenerate the CSS every time you modify the SCSS files.
|
|
* Note that meson always builds out-of-tree, so the modified css files will
|
|
appear in your builddir.

How to tweak the theme
|
|
----------------------
|
|
|
|
Adwaita is a complex theme, so to keep it maintainable it's written and
|
|
processed in SASS. The generated CSS is then transformed into a gresource file
|
|
during gtk build and used at runtime in a non-legible or editable form.
|
|
|
|
It is very likely your change will happen in the _common.scss file. That's where
|
|
all the widget selectors are defined. Here's a rundown of the "supporting"
|
|
stylesheets, that are unlikely to be the right place for a drive by stylesheet
|
|
fix:
|
|
|
|
_colors.scss - global color definitions. We keep the number of defined
|
|
colors to a necessary minimum, most colors are derived
|
|
from a handful of basics. It covers both the light variant
|
|
and the dark variant.
|
|
|
|
_colors-public.scss - SCSS colors exported through gtk to allow for 3rd party
|
|
apps color mixing.
|
|
|
|
_drawing.scss - drawing helper mixings/functions to allow easier
|
|
definition of widget drawing under specific context. This
|
|
is why Adwaita isn't 15000 LOC.
|
|
|
|
_common.scss - actual definitions of style for each widget. This is
|
|
where you are likely to add/remove your changes.
|
|
|
|
You can read about SASS at http://sass-lang.com/documentation/. Once you make
|
|
your changes to the _common.scss file, GTK will rebuild the CSS files.
