emacs shell:用ido更改目录
我越来越多地使用emacs shell模式,并且有一些我希望可以改进的地方:改变目录时的完成。 我很乐意使用ido
或者projectile-find-dir
。
我的工作流程
截至今天我尽我所能的Emacs的外壳之外,尽可能多使用emacs的力量尽可能(访问文件与IDO,查找文件的项目, projectile
,探索里面dired,...树)。
我不经常光顾。 当我在另一个项目中工作时,我打开另一个shell缓冲区。 但是当我必须的时候,我真的很想念ido或fasd shell实用程序(它可以工作,但是没有它的完成界面,这对zsh很有用,而且不像ido的使用可以是https:// github那样强大。 COM / clvv / FASD)。
如何在elisp中连线?
我知道我们可以给ido-completing-read
列表;
在shell中,输入cd ../<TAB>
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?
谢谢 !
编辑 :这是另一个很好的方式来cd到最近访问的目录,与fasd实用程序和ido完成:https://gitlab.com/emacs-stuff/fasd-shell/blob/master/README.org
看另一个SO问题。
ps:eshell在某些shell脚本中运行不正常,我想保持shell模式。
试试这个,它是一个快速和肮脏的黑客攻击,可能在某些情况下失败,但应该一般工作。 也请原谅我的elisp

如果当前输入的命令是cd
,则在shell中按<tab>
将会提示使用ido可用的目录,否则它将回退到默认完成状态,退出按C-RET
