pub fn cpp_displaced_preprocessor_branch<'tree>(
conditional: Node<'tree>,
) -> Option<Node<'tree>>Expand description
The first #else/#elif of conditional that tree-sitter displaced into
an ERROR inside the conditional’s own branch.
The macro-declaration grammar can read an unterminated end sentinel, the
branch directive and the next branch’s begin sentinel as one declaration
(END_NS #else BEGIN_NS class C {};, #6325): the #else becomes an
ERROR child and the conditional loses its alternative. The token is
still the structured branch boundary. Nested conditionals own their own
directives, including ones represented only by error-owned #if/#endif
tokens, so the walk pairs those the same way
cpp_displaced_preprocessor_terminator does.
