Functions

func GetLanguage

func GetLanguage(l lang.Language) (*tree_sitter.Language, error)

GetLanguage returns the tree-sitter Language for a lang.Language.

func NodeText

func NodeText(node *tree_sitter.Node, source []byte) string

NodeText returns the text content of a node.

func Parse

func Parse(l lang.Language, source []byte) (*tree_sitter.Tree, error)

Parse parses source code into a tree-sitter AST Tree. The caller must call tree.Close() when done. Parsers are pooled per language via sync.Pool to avoid per-file allocation.

func Walk

func Walk(node *tree_sitter.Node, fn WalkFunc)

Walk traverses the AST in depth-first order.

Types

type WalkFunc

type WalkFunc func(node *tree_sitter.Node) bool

WalkFunc is called for each node during AST traversal. Return false to skip children.
