我目前正在用Python开发一个包含40个子命令的程序。解析器使用argparse完成。随着子命令数量的增加,搜索感兴趣的命令变得越来越复杂。目前,它显示如下。
$ 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.
我想更改显示以便显示类别(例如更新/插入/选择)和相关的子命令。
$ 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…
argparser中是否有可以用来实现这种CLI的解决方案?
谢谢你
最佳答案
我几年前就探讨过这个问题
http://bugs.python.org/issue9341
允许对argparse子命令进行分组
如果我正确地阅读了我建议的补丁,它只需要更改_SubParsersAction
类,而不需要进一步更改HelpFormatter
或ArgumentParser
类。
