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

问题描述

我也想在参数中自动完成我的 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 bash_completion 是如何工作的(用于参数)，但在我深入研究之后我明白了:

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

1. 它使用完成"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

特别是第二点不是很好，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.

最好的事情是 shell 在每个 TAB 处询问我的程序要完成什么，但我的印象是这不能真正起作用，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?

第二个选项可能只是编写一个从 argparse 解析器到正确完成的 shell 函数的转换器.

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

无耻的自我推销:https://github.com/kislyuk/参数完整

argcomplete 为 argparse 提供 bash 补全.

argcomplete provides bash completion for argparse.
