Python argparse和bash完成 [英] Python argparse and bash completion

问题描述

我想在参数中也自动完成我的python脚本.

I would like to get auto-completion on my python scripts also in the arguments.

我从来没有真正理解过bash_completion是如何工作的(用于参数)，但是当我深入研究后，我明白了:

I had never really understood how the bash_completion worked (for arguments), but after I digged in I understood that:

1. 它使用"complete"将完成功能绑定到命令
2. 每个完成函数基本上都是参数解析器的副本

第二点特别不好，因为我想让它自动生成.

The second point in particular is not great, because I would like to have it automatically generated.

最好的办法是，shell在每个TAB处都向我的程序询问要完成什么，但是我有一种印象，那就是这真的行不通，对吗?

The best thing would be that the shell asks to my program at every TAB about what to complete, but I have the impression that this can't really work, is that correct?

第二种选择可能只是将一个转换器从argparse解析器写入正确完成的shell函数.

The second option is probably just to write a converter from an argparse parser to a shell function which completes correctly.

推荐答案
