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?

  • 是否有可能将完成列表连接到ido? (或射弹或头盔或其他)
  • 如果您将我链接到准确的文档(有很多,很难知道对我有用)
  • 还是存在一种解决方案?
  • 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

    (require 'ido)

        (if (and (>= (length user-input) 3)
                 (string= (substring user-input 0 3) "cd "))
            (progn 
              (setq my-dir-selected nil)
              (while (not my-dir-selected)
                (my-complete-directory-name default-directory

                                        (point-max))))
              (comint-send-input))
          (call-interactively 'completion-at-point))))
    
    (define-key shell-mode-map (kbd "<tab>") 'my-prompt-for-dir-or-fallback)
    
    (add-hook 'ido-setup-hook 'ido-my-keys)
    
    (defun ido-my-keys ()
      "Add my keybindings for ido."
      (define-key ido-completion-map (kbd "<C-return>") (lambda ()
                                                            (interactive)
                                                            (setq my-dir-selected t)
                                                            (ido-exit-minibuffer))))
    

    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
