tui.load_theme

tui.load_theme FILE

Loads a stylesheet into the class table. <theme src="…"/> calls it.

Returns: 1 and a message on stderr when FILE can’t be read or parsed.

Notes

• Rules merge into one table: a later file overrides the fields it sets, and nothing is removed. Classes from a theme loaded on an earlier page stay defined.
• Each file is parsed once per process and re-applied from memory until its mtime changes.
• The app-wide overlay from tui.theme.set is re-applied after every stylesheet, so it always wins.
• Widgets already styled with tui.class keep their old colors; load themes before applying classes.
• Class names that collide with a widget or pane style are logged as warnings.
