Function ListFiles

script.go:141–166

ListFiles creates a pipe containing the files or directories specified by path, one per line. path can be a glob expression, as for [filepath.Match]. For example: ListFiles("/data/*").Stdout() ListFiles does not recurse into subdirectories; use [FindFiles] instead.

(path string)

//
// ListFiles does not recurse into subdirectories; use [FindFiles] instead.
func ListFiles(path string) *Pipe {
	if strings.ContainsAny(path, "[]^*?\\{}!") {
		fileNames, err := filepath.Glob(path)
		if err != nil {
			return NewPipe().WithError(err)
		}
		return Slice(fileNames)
	}
	entries, err := os.ReadDir(path)
	if err != nil {
		// Check for the case where the path matches exactly one file
		s, err := os.Stat(path)
		if err != nil {
			return NewPipe().WithError(err)
		}
		if !s.IsDir() {
			return Echo(path)
		}
		return NewPipe().WithError(err)
	}
	matches := make([]string, len(entries))
	for i, e := range entries {
		matches[i] = filepath.Join(path, e.Name())
	}
	return Slice(matches)
}

// NewPipe creates a new pipe with an empty reader (use [Pipe.WithReader] to
// attach another reader to it).
