Struct Theme 

pub struct Theme { /* private fields */ }

A container for style information.

Themes map style names (like “repr.number”) to Style objects. They can optionally inherit from the default styles.

Implementations

impl Theme

pub fn new() -> Self

Create an empty theme that inherits default styles.

pub fn empty() -> Self

Create an empty theme without default styles.

pub fn with_styles(styles: HashMap<String, Style>, inherit: bool) -> Self

Create a theme with custom styles, optionally inheriting defaults.

pub fn read<P: AsRef<Path>>(path: P, inherit: bool) -> Result<Self, ThemeError>

Read a theme from an INI-like config file.

Format

[styles]
repr.number = bold cyan
repr.string = green

pub fn from_file<P: AsRef<Path>>(path: P) -> Result<Self, ThemeError>

Read a theme from a file (convenience wrapper for read).

pub fn from_reader<R: BufRead>( reader: R, inherit: bool, ) -> Result<Self, ThemeError>

Parse a theme from a reader.

pub fn get_style(&self, name: &str) -> Option<Style>

Get a style by name.

pub fn add_style(&mut self, name: impl Into<String>, style: Style)

Add or update a style.

pub fn remove_style(&mut self, name: &str) -> Option<Style>

Remove a style by name.

pub fn has_style(&self, name: &str) -> bool

Check if a style exists.

pub fn style_names(&self) -> impl Iterator<Item = &str>

Get all style names.

pub fn len(&self) -> usize

Get the number of styles.

pub fn is_empty(&self) -> bool

Check if the theme is empty.

pub fn inherits(&self) -> bool

Whether this theme inherits default styles.

pub fn to_config(&self) -> String

Generate INI config file contents for this theme.

pub fn from_name(name: &str) -> Option<Self>

Load a theme by name.

Available themes:

• "default" - The default rich-rs theme
• "dracula" - Dark theme with purple accents
• "gruvbox-dark" - Retro groove dark theme
• "nord" - Arctic, north-bluish color palette

Example

use rich_rs::Theme;

let theme = Theme::from_name("dracula").unwrap();
assert!(theme.get_style("repr.number").is_some());

pub fn available_themes() -> Vec<&'static str>

List available theme names.

Example

use rich_rs::Theme;

let themes = Theme::available_themes();
assert!(themes.contains(&"dracula"));
