Struct SyntectStrategy 

pub struct SyntectStrategy { /* private fields */ }

Syntax highlighting strategy powered by syntect.

Implementations

impl SyntectStrategy

pub fn load_defaults() -> Self

Load default syntaxes and themes from syntect.

pub fn with_sets(syntax_set: Rc<SyntaxSet>, theme_set: Rc<ThemeSet>) -> Self

Construct with custom syntax/theme sets.

pub fn default_theme(self, theme: impl Into<Arc<str>>) -> Self

Set the default theme name used when TextArea doesn’t specify one.

pub fn use_background(self, enabled: bool) -> Self

Control whether syntect background colors are applied.

Default is false to keep TextArea background styling.

pub fn syntax_palette(self, palette: SyntaxPalette) -> Self

Override syntect token colors with a semantic syntax palette.

This is applied as a hybrid layer on top of the syntect theme instead of replacing tokenization or modifiers entirely.

pub fn document_palette(self, palette: DocumentPalette) -> Self

Override markdown scope colors with a document palette.

Takes precedence over the document palette from ThemeProvider. When neither is set, markdown scopes use the underlying tmTheme’s defaults.

pub fn set_app_theme_if_absent(&mut self, theme: AppTheme)

Set the app theme only when one has not already been applied.

This preserves the innermost ThemeProvider semantics, matching how normal widget styles keep explicitly themed inner values when an outer provider is applied later during runtime wrapping.

pub fn custom_theme( self, name: impl Into<Arc<str>>, content: impl AsRef<str>, ) -> Result<Self>

Add a custom theme from a tmTheme XML string.

pub fn custom_theme_bytes( self, name: impl Into<Arc<str>>, bytes: impl AsRef<[u8]>, ) -> Result<Self>

Add a custom theme from tmTheme bytes.

pub fn custom_theme_from_file( self, name: impl Into<Arc<str>>, path: impl AsRef<Path>, ) -> Result<Self>

Add a custom theme from a tmTheme file path.

pub fn language_for_path(&self, path: impl AsRef<Path>) -> Option<Arc<str>>

Resolve a language name from a file path using extension and filename matching.

Does not read the file - only the path components are inspected. TypeScript/TSX paths fall back to JavaScript/JSX-compatible syntaxes when the active syntax set does not provide exact grammars. Returns the canonical language name (e.g. "Rust", "Python") or None.

pub fn language_for_path_and_first_line( &self, path: impl AsRef<Path>, first_line: &str, ) -> Option<Arc<str>>

Resolve a language name from a file path, falling back to first-line (shebang / mode line) detection if extension matching fails.

The caller must supply the first line - this method does no I/O.
