(:kind)

TreeSitter node kind matching

(:kind val)

Where:

1. val: TreeSitter node kind to match *

Behavior

• Matches nodes by their TreeSitter grammar kind name (e.g., 'identifier', 'string_node', 'call_expression').
• Useful as an escape hatch when SYNG doesn't expose a specific node type as a selector, or when you need language-specific matching.
• Kind names are grammar-specific and may differ between languages (JavaScript's 'identifier' vs Rust's 'scoped_identifier').

Examples

Extract TODO and FIXME comments from code for issue tracking.

(:and (:kind /comment/) (:text /TODO|FIXME/))

Selects in lines { 1, 2 } but not in { 3, 4 }:

// TODO: optimize this algorithm
/* FIXME: handle edge case */
// Regular comment
const x = 1;

---

Locate Rust token trees that aren't parsed into structured macro bodies.

(:kind "token_tree")

Selects in lines { 2 } but not in { }:

macro_rules! m {
  () => { Foo::Bar }
}

---

Match TypeScript-specific type annotation nodes.

(:kind "type_annotation")

Selects in lines { 1, 1 } but not in { }:

function f(x: number): string {
  return String(x);
}
