class CapturableVersionAction(argparse.Action): (source)

View In Hierarchy

Supplement CapturableArgumentParser to handle --version.

This is nearly identical to argparse._VersionAction except, like CapturableArgumentParser, it allows output to be captured.

Another notable difference is that version is mandatory. This allows removing a line in __call__ that falls back to parser.version (which does not appear to exist).
