Function findCaretTokenIndex

backend/plugin/parser/pg/completion.go:180–187

findCaretTokenIndex returns the index of the first token whose start (Loc) is at or past byteOffset. This matches ANTLR Scanner.SeekPosition semantics: the caret token is the one that starts at or after the cursor position. Uses >= so that when the cursor is exactly at a token boundary, we pick that

(tokens []pgparser.Token, byteOffset int)

// that token (not the one before it).
// Returns len(tokens) if all tokens are before byteOffset.
func findCaretTokenIndex(tokens []pgparser.Token, byteOffset int) int {
	for i, tok := range tokens {
		if tok.Loc >= byteOffset {
			return i
		}
	}
	return len(tokens)
}

func (c *Completer) completion() ([]base.Candidate, error) {
	// Check if the caret token is quoted.
