我越来越多地使用emacs shell模式,我希望可以改进一些东西:更改目录时的完成。我很想用ido或projectile-find-dir来做这个。
我的工作流
从今天起,我尽我所能在emacs的外壳之外,尽可能地使用emacs的功能(使用ido访问文件,用projectile在项目中查找文件,探索dired,…中的树)。。
我不常听cd。当我在不同的项目中工作时,我会打开另一个shell缓冲区。但是当我必须这样做的时候,我真的很想念ido或者fasd shell实用程序(它可以工作,但是没有它的完成界面-它与zsh很好,而且它没有ido的使用强大到可以是https://github.com/clvv/fasd)。
如何用elisp ?连接
我知道我们可以给ido-completing-read一个列表;
在shell中,键入cd ../<TAB>将打开一个新的*Completions*缓冲区。它使用comint-dynamic-completion,但是如何在elisp列表中,而不是在缓冲区中获得该列表?
谢谢!
编辑:下面是最近访问目录的另一种很好的方式,使用fasd实用程序和ido完成:https://gitlab.com/emacs-stuff/fasd-shell/blob/master/README.org
ps:一些shell脚本不能很好地工作,我想保持shell模式。

尝试一下,这是一个快速和肮脏的黑客,在某些情况下可能会失败,但一般情况下应该有效。也请原谅我的私奔
