获取compgen寻找文件时，列入目录的斜杠 [英] Getting compgen to include slashes on directories when looking for files

问题描述

我想从我的自定义完成后得到以下行为

I'd like to get the following behavior from my custom completion

由于

$ mkdir foo
$ touch foo faz/bar faz/baz

我想获得这个

$ foo -u <tab><tab> =>
foo faz/

$ foo -u fa<tab><tab> =>
foo -u faz/

$ foo -u faz/<tab><tab> =>
bar baz

我认为 compgen -ff 将输出富FAZ / ，但它输出富FAZ 这并不能帮助我很多。

I assumed that compgen -f f would output foo faz/, but it outputs foo faz which doesn't help me much.

我是否需要后处理的输出或者是有选项一些魔法组合compgen工作？

Do I need to post-process the output or is there some magic combination of options to compgen that work?

推荐答案

我遇到了同样的问题。下面是我使用的解决方法：

I ran into the same problem. Here's the workaround I'm using:

1. 注册的完成函数 -o默认，例如完整-o默认-F _my_completion 。


2. 当你想完成一个文件名，只需设置 COM prePLY =（），让Readline的接管（这是什么 - Ø默认一样）。

1. Register the completion function with -o default, e.g., complete -o default -F _my_completion.
2. When you want to complete a filename, just set COMPREPLY=() and let Readline take over (that's what the -o default does).

有与这个潜在的问题 - 你可能会使用 COM prePLY =（）拒绝完成它是不恰当的，现在不会工作了。在bash 4.0以上，就可以解决这个使用 compopt 如下：

There's a potential problem with this -- you might be using COMPREPLY=() to deny completion where it's not appropriate, and now that won't work anymore. In Bash 4.0 and above, you can work around this using compopt as follows:

1. 在您完成功能的顶部，始终运行 compopt + O默认。这将禁用的ReadLine文件名完成时， COM prePLY 是空的。


2. 当你想完成一个文件名，使用 compopt -o默认; COM prePLY =（）。换句话说，让Readline的文件名完成，只有当你需要它。

1. At the top of your completion function, always run compopt +o default. This disables Readline filename completion when COMPREPLY is empty.
2. When you want to complete a filename, use compopt -o default; COMPREPLY=(). In other words, enable Readline filename completion only when you need it.

我还没有想出了pre-4.0 Bash的一个完整的解决办法，但我有一些很好的作品对我来说足够。我可以形容这是否有人真正关心，但希望这些旧的Bash版本很快就会出来共同使用无论如何。

I haven't figured out a full workaround for pre-4.0 Bash, but I have something that works well enough for me. I can describe this if anyone really cares, but hopefully these older Bash versions will soon fall out of common use anyway.
