Class Method Details

.filter(files, since: nil, before: nil) ⇒ Array<String>

Filter files by time criteria

Parameters:

  • files (Array<String>) —

    List of file paths

  • since (Time, String, nil) (defaults to: nil) —

    Only files modified after this time

  • before (Time, String, nil) (defaults to: nil) —

    Only files modified before this time

Returns:

  • (Array<String>) —

    Filtered list of files
