- Detect terminal color support and automatically switch to the new `ansi_basic` theme when only 16‑color support is available. - Introduce `OfflineProvider` that supplies a placeholder model and friendly messages when no providers are reachable, keeping the TUI usable. - Add `CONFIG_SCHEMA_VERSION` (`1.1.0`) with schema migration logic and default handling in `Config`. - Update configuration saving to persist the schema version and ensure defaults. - Register the `ansi_basic` theme in `theme.rs`. - Extend `ChatApp` with `set_status_message` to display custom status lines. - Update documentation (architecture, Vim mode state machine) to reflect new behavior. - Add async‑trait and futures dependencies required for the offline provider implementation.

# Background colors
background = "#000000" # Main background
command_bar_background = "#111111"

selection_fg = "#ffffff" # Selection foreground
cursor = "#ff0080" # Cursor color
# Status colors

Color Format
Colors can be specified in two formats:
- Hex RGB:
#rrggbb(e.g.,#ff0000for red,#ff8800for orange) - Named colors (case-insensitive):
- Basic:
black,red,green,yellow,blue,magenta,cyan,white - Gray variants:
gray,grey,darkgray,darkgrey - Light variants:
lightred,lightgreen,lightyellow,lightblue,lightmagenta,lightcyan
- Basic:
Note: For colors not in the named list (like orange, purple, brown), use hex RGB format.
OWLEN will display an error message on startup if a custom theme has invalid colors.
Creating Custom Themes
To create your own theme:
- Copy one of these files to
~/.config/owlen/themes/ - Rename and modify the colors
- Set
theme = "your-theme-name"in~/.config/owlen/config.toml - Or use
:theme your-theme-namein OWLEN to switch
Embedding in Binary
These theme files are embedded into the OWLEN binary at compile time using Rust's include_str!() macro. This ensures they're always available, even if the files are deleted from disk.
Custom themes placed in ~/.config/owlen/themes/ will override built-in themes with the same name.
