You can already access them via node.range()

Example code

ast-grep/crates/pyo3/src/range.rs

Lines 100 to 112 in 989f040

 impl Range { 

 pub fn from<D: Doc>(node: &Node<D>, positioner: &UnicodePosition) -> Self { 

 let byte_range = node.range(); 

 let start_pos = node.start_pos(); 

 let end_pos = node.end_pos(); 

 let start = positioner.byte_to_char(byte_range.start); 

 let end = positioner.byte_to_char(byte_range.end); 

 Range { 

 start: to_pos(start_pos, start), 

 end: to_pos(end_pos, end), 

 } 

 } 

 }

Indeed, thank you and sorry for bothering

If you are integrating ast-grep into other programming language, the napi and pyo3 folders will be very helpful.

One particular thing you may need pay attention to is the text encoding. Tree-sitter returns a byte offset in utf8 or utf16, which is usually not how programming languages handle character offsets.

Thanks for the hints, I'm definitely following the pyo3 implementation
