Victor Porton <por...@narod.ru> added the comment:
Subparsers are added like:
subparsers.add_parser('checkout', aliases=['co'])
But I want to use a parser BOTH as a subparser and as a full-fledged parser.
It is because my program should understand both of the following command line
options:
boiler chain -t http://www.w3.org/1999/xhtml -W inverseofsum
and
boiler pipe 'chain -t http://www.w3.org/1999/xhtml -W inverseofsum +
transformation http://example.com/ns1'.
I split it (at +) into several lists of arguments as explained in
https://stackoverflow.com/a/53750697/856090
So I need `chain` both as a subparser and as a standalone parser of `-t
http://www.w3.org/1999/xhtml -W inverseofsum`.
So, feature which I want:
subparsers.add_parser('checkout', aliases=['co'], parser=...)
where ... is a reference to a parser object.
