Function isNewlineEnding

agent/agentfiles/files.go:664–666

isNewlineEnding reports whether s is one of the newline-class endings: "\n" or "\r\n". Shared primitive for endingsMatch (matching phase) and endingShapeEqual (splice phase) so a new ending class added in one predicate can't silently diverge from the other.

(s string)

// ending class added in one predicate can't silently diverge from
// the other.
func isNewlineEnding(s string) bool {
	return s == "\n" || s == "\r\n"
}

// internalLineEnding returns the shared line ending used across
// lines. An unterminated last line (EOF-no-newline) is excluded.
