Struct LanguageRegistry 

pub struct LanguageRegistry { /* private fields */ }

Implementations

impl LanguageRegistry

pub fn syntactic_emphasis(&self, file: &mut FileDiff) -> bool

Set char-precise emphasis on file’s diff lines from the AST diff. Returns false when the syntactic engine is unavailable, so the caller can fall back to the textual engine.

impl LanguageRegistry

pub fn build() -> Self

Build the registry with every bundled grammar, reused for the session.

pub fn for_path(&self, path: &str) -> Option<&LangEntry>

The entry whose grammar handles path, keyed by file extension.

pub fn for_token(&self, token: &str) -> Option<&LangEntry>

The entry for a markdown fence token (rust, py, c++, …), matched by grammar name then extension.

pub fn config_for_injection( &self, lang: &str, ) -> Option<&HighlightConfiguration>

Highlight config for a tree-sitter injection language name (the inline markdown grammar, or a fenced code block’s language). None leaves the injected region plain.

pub fn markdown_inline_spans( &self, content: &str, ) -> Vec<(Range<usize>, &'static str)>

Inline markdown captures (emphasis, code spans, links) as byte range plus the recognized highlight name, narrowest span first so a first-match renderer picks the most specific. The inline grammar parses only the block grammar’s (inline) node ranges, so block markers stay untouched.

impl LanguageRegistry

pub fn scope_index(&self, path: &str, content: &str) -> ScopeIndex

Parse content and index its definition spans for scope lookup. Returns an empty index when the language is unsupported, has no tags query, the file is too large, or parsing fails — callers then show no breadcrumb.

Trait Implementations

impl Default for LanguageRegistry

fn default() -> Self

Returns the “default value” for a type.
