Arc-39-theme/HACKING.md

This theme uses node-sass/libsass to process the various .scss files. Never edit any of the .css files manually.

Editing the CSS based themes in the common directory (cinnamon, gnome-shell, gtk-3.0)

• Edit the common/*/sass/*.scss files

• Run make to generate all css files using sassc (starting with version 20180114). Gulp is no longer required.

Editing the GTK 2 themes

• Go to common/gtk-2.0

• The colors and includes are defined in light/gtkrc, dark/gtkrc and darker/gtkrc for each theme variant

• main.rc contains the major part of the theme

• panel.rc contains the panel styling for Xfce and MATE

• apps.rc contains some application specific rules

Because this theme is heavily based on the pixmap engine, a lot of the styling comes from the images in the light/assets and dark/assets folders. Don't edit these images directly. See the next section.

Editing the images for the GTK 2 and GTK 3 themes

• Go to the common/gtk-2.0/light, common/gtk-2.0/dark, or common/gtk-3.0/$gtk-version directory.

• Open the assets.svg file in inkscape. Each object in the .svg file corresponds to an image in the assets folder.

• Find the object you want to edit and make your changes. Important: Don't change the object id!

• Save assets.svg and run make (or make -j$(nproc) if you're in a hurry) from a terminal in the parent directory.
