Struct LanguageRegistry 

pub struct LanguageRegistry { /* private fields */ }

Implementations

impl LanguageRegistry

pub fn syntactic_emphasis( entry: Option<&LangEntry>, file: &mut FileDiff, mark_reformat_only: bool, ) -> bool

Set emphasis on file’s diff lines from an AST diff of both sides. mark_reformat_only also flags paired lines that differ in layout alone. Returns false when the file cannot be diffed this way, so the caller falls back to the textual engine.

impl LanguageRegistry

pub fn build() -> Self

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

By exact file name, then extension.

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

Self::for_path, then a naming convention, then the #! line.

pub fn by_name(&self, name: &str) -> Option<&LangEntry>

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

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

A markdown fence token, by grammar name then extension.

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

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

Inline markdown captures with their highlight name, narrowest first so a first-match renderer picks the most specific.

impl LanguageRegistry

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

Empty when the file has no grammar or tags query, is too large, or fails to parse.

pub fn scope_index_as(entry: Option<&LangEntry>, content: &str) -> ScopeIndex

Self::scope_index with content parsed as entry’s language.

impl LanguageRegistry

pub fn symbols(&self, path: &str, content: &str) -> (Vec<Ident>, ScopeIndex)

Every identifier in content and its definition spans, from one parse. Without a parse we fall back to plain words, strings and comments included.

Trait Implementations

impl Default for LanguageRegistry

fn default() -> Self

Returns the “default value” for a type.
