I am currently developing a program in Python that contains ~40 sub commands. The parser is done using argparse. As the number of sub commands increases it is becoming complicated to search for the command of interest. Currently, it appears as below.
$ pgrm -h
Usage: pgrm [-h] [-v] ...
Blabla bla.
Main command arguments:
-h, --help show this help message and exit
-v, --version show program's version number and exit
Available sub-commands:
sub_cmd Some description about the command…
sub_cmd Some description about the command…
sub_cmd Some description about the command…
sub_cmd Some description about the command…
sub_cmd Some description about the command…
sub_cmd Some description about the command…
sub_cmd Some description about the command…
sub_cmd Some description about the command…
sub_cmd Some description about the command…
sub_cmd Some description about the command…
sub_cmd Some description about the command…
Usage example:
'pgrm sub-command -h' for more information.
I would like to change the display in order to show categories (e.g updating/inserting/selecting) and associated subcommands.
$ pgrm -h
Usage: pgrm [-h] [-v] ...
Blabla bla.
Main command arguments:
-h, --help show this help message and exit
-v, --version show program's version number and exit
Available sub-commands:
Updating
sub_cmd Some description about the command…
sub_cmd Some description about the command…
sub_cmd Some description about the command…
sub_cmd Some description about the command…
Selecting
sub_cmd Some description about the command…
sub_cmd Some description about the command…
sub_cmd Some description about the command…
Inserting
sub_cmd Some description about the command…
sub_cmd Some description about the command…
sub_cmd Some description about the command…
sub_cmd Some description about the command…
Is there any solution that can be used in argparser to implement such CLI ?
Thank you
