Improved icon theme helper (#144)
* Small refactor for the get_client_icon_path function * Try to match first by icon name and then by class * Formatting * It's dashes * Use methods * Why check it every loop? * Try to get icon by the retriving the command from the pid * Split into multiple functions * No newline at eof * Remove empty line * Gets only the process name instead of the full command * Double quotes everywhere * I don't need pattern matching * I want the executable * Check if pid is nil * Use client icon if not found * Class can be nil for some clients too? * Check for nil values * Lgi doesn't work with gtk 4.0 * Fix class being nil * client.icon can be nil as well
