我越来越多地使用emacs
shell模式,并且我希望可以改进一些东西：更改目录时完成.我喜欢用ido或者projectile-find-dir.
我的工作流程
截至今天,我尽力在emacs的shell之外,尽可能地使用emacs的强大功能(使用ido访问文件,使用projectile查找项目中的文件,探索dired中的树,…).
我不经常这样做.当我在一个不同的项目中工作时,我打开另一个shell缓冲区.但是当我不得不这样做的时候,我真的很想念ido或者fasd shell实用程序(它有效,但是没有它的完成界面,这对zsh很有用,并且不像使用ido那样强大,可能是https://github.com/clvv/fasd).
如何在elisp中连接？
我知道我们可以列出ido-completed-read;
在shell中,输入cd ../\u0026lt;TAB\u0026gt;打开一个新的* Completions *缓冲区.它使用comint-dynamic-completion,但是如何在elisp列表中获取该列表,而不是在缓冲区中？
>是否有可能将完成列表连接到ido？ (或抛射物或舵或其他)
>如果你把我链接到准确的文档(我有很多,很难知道什么对我有用),我也很感激.

谢谢 ！
编辑：这是cd到最近访问过的目录的另一个好方法,使用fasd实用程序和ido完成：https://gitlab.com/emacs-stuff/fasd-shell/blob/master/README.org
ps：eshell不适用于某些shell脚本,我想保持shell模式.
试试这个,这是一个快速而肮脏的黑客,在某些情况下可能会失败,但应该通常工作.还原谅我的elisp
