zsh:键入命令Y时，对命令X使用补全 [英] zsh: use completions for command X when I type command Y

问题描述

在zsh中，我有一个名为g的函数，其功能如下:

In zsh, I have a function called g which acts like this:

• 没有参数，请调用git status
• 具有一个或多个参数，将所有给定参数委托给git-即调用git $@

• with no arguments, call git status
• with one or more arguments, delegate to git with all given arguments - i.e. call git $@

我希望g的制表符补全与git的制表符完全相同.我可以使用alias g=git实现此功能，但是默认情况下(上面的第一点)不允许我调用status.

I would like the tab completions for g to be exactly the same as for git. I can achieve this with alias g=git, but that doesn't allow me to call status by default (the first point above).

如何委派git的完成?

在bash中，我只是做了complete -F _git g，它重新使用了git的完成功能.使用zsh，git的完成看起来要复杂得多，而且我无法找到类似的解决方案.

In bash, I simply did complete -F _git g which re-uses git's completion function. With zsh, git's completion looks much more complex, and I wan't able to find a similar solution.

我猜zsh中有一些功能说假装我键入了命令[x]，您要完成什么操作?".如果我知道那是什么，那么使用函数委托它应该足够简单.但是我在手册中没有找到这样的功能.

I'd guess there's some function in zsh to say "pretend I typed command [x], what would you complete it to?". If I knew what that was, it should be simple enough to use a function to delegate to it. But I've found no such function in the manuals.

推荐答案

这样说:

功能compdef可用于将现有完成功能与新命令关联.例如

The function compdef can be used to associate existing completion functions with new commands. For example,

compdef _pids foo

但是修改它(_git是 git 的常用完成函数)并没有为我带来任何工作效果(即使在自动加载_git之后):

But adapting it (_git is the usual completion function for git) did not produce a working result for me (even after _git had been autoloaded):

compdef _git g

尽管如此，我还是可以通过_dispatch使它工作:

I was able to get it to work via _dispatch though:

compdef '_dispatch git git' g
