notification_settings

Get the glyph set for the current charset mode.

Check whether the terminal is in ASCII charset mode.

Convenience wrapper so widgets can branch on charset without importing both _detect_charset_mode and CharsetMode.

Modal dialog for managing startup warning preferences.

Each checkbox maps to a key in [warnings].suppress in ~/.deepagents/config.toml. Toggling a checkbox immediately persists the change.

LangChain brand colors and semantic constants for the app.

Single source of truth for color values used in Python code (Rich markup, Content.styled, Content.from_markup). CSS-side styling should reference Textual CSS variables: built-in variables ($primary, $background, $text-muted, $error-muted, etc.) are set via register_theme() in DeepAgentsApp.__init__, while the few app-specific variables ($mode-bash, $mode-command, $mode-incognito, $skill, $skill-hover, $tool, $tool-hover) are backed by these constants via App.get_theme_variable_defaults().

Code that needs custom CSS variable values should call get_css_variable_defaults(dark=...). For the full semantic color palette, look up the ThemeColors instance via get_registry().

Users can define custom themes in ~/.deepagents/config.toml under [themes.<name>] sections. Each new theme section must include label (str); dark (bool) defaults to False if omitted (set to True for dark themes). Color fields are optional and fall back to the built-in dark/light palette based on the dark flag. Sections whose name matches a built-in theme override its colors without replacing it. See _load_user_themes() for details.
