Struct MarkdownTree 

pub struct MarkdownTree { /* private fields */ }

Wraps a tree-sitter parser configured for markdown. Supports incremental re-parsing after edits.

Implementations

impl MarkdownTree

pub fn new(source: &str) -> Self

Create a new markdown parser and parse the given source.

pub fn source(&self) -> &str

Get the current source text.

pub fn tree(&self) -> Option<&Tree>

Get the current parse tree, if available.

pub fn set_source(&mut self, source: &str)

Replace the entire source and re-parse from scratch.

pub fn edit( &mut self, start_byte: usize, old_end_byte: usize, new_text: &str, start_point: Point, old_end_point: Point, )

Apply an edit and incrementally re-parse.

start_byte / old_end_byte / new_end_byte describe the edit in byte offsets. Points describe the same edit in row/column coordinates.

Panics

Panics if start_byte or old_end_byte are not on UTF-8 char boundaries.

pub fn sexp(&self) -> Option<String>

Get the S-expression representation of the parse tree (for debugging).

pub fn walk_blocks<F>(&self, visitor: F)

where F: FnMut(BlockInfo),

Walk the top-level blocks of the document, calling the visitor for each.

pub fn block_at_byte(&self, byte_offset: usize) -> Option<BlockInfo>

Find the block node at the given byte offset.

pub fn node_at_byte(&self, byte_offset: usize) -> Option<NodeInfo>

Find the innermost node at the given byte offset.
