pub struct ScopeParser;Expand description
Parses language scope annotations from document text.
Supports the following marker formats:
<!-- lang: xx -->(HTML/Markdown comments)// @lang: xx(line comments)/* @lang: xx */(block comments)% @lang: xx(LaTeX comments)
Implementations§
Source§impl ScopeParser
impl ScopeParser
Sourcepub fn parse(text: &str) -> Vec<ScopedRegion>
pub fn parse(text: &str) -> Vec<ScopedRegion>
Extract all language scope regions from the given text.
Returns scoped regions sorted by byte offset. Text between the start of the document and the first marker (or with no markers at all) is not included - the caller should fall back to the default language for those ranges.
Sourcepub fn language_at(regions: &[ScopedRegion], byte_offset: usize) -> Option<&str>
pub fn language_at(regions: &[ScopedRegion], byte_offset: usize) -> Option<&str>
Look up the language for a given byte offset, if it falls within a scoped region.
