The query
(_ . (_) @firstChild)will correctly capture the first child of every named nodereturns:
function_definitionand the firstidentifier✅however if you specify a node name inside of
(_), the query will instead capture every single node of that nameregardless of if its the first named node or not
(_ . (identifier) @everyChild)returns:
function_definitionand every singleidentifier❌specifying the parent name does work correctly:
(function_definition . (identifier) @firstChild)returns: the first
identifier✅https://github.com/tree-sitter/tree-sitter/blob/master/docs/section-2-using-parsers.md#anchors
