在Emacs中使用z（跳转）查找目录 [英] Use z (jump around) in Emacs to find directories

问题描述

Z 是一种常用的shell工具，用于跳过常用的目录。它使用freecency作为衡量您打算跳转到哪个目录的指标关键字完成。所以如果我通常光盘到〜/ .ssh ，我可以 z ssh 跳到那里。

Z is a popular shell tool for jumping around commonly used directories. It uses "frecency" as a metric for determining which directory you intend to jump to based on keyword completions. So if I commonly cd to ~/.ssh, I can z ssh to jump there.

我的问题是如何获得与Emacs相同的功能？也就是说，我想要使用 ido-find-file 或类似的东西，但只需键入几个字符即可跳转到我想要的目录。希望解决方案可以包含 z 本身，因此它可以利用已经由 z 记录的频率度量。

My question is how can I get the same functionality to work inside Emacs? That is, I want to be able to use ido-find-file or something similar but only have to type a few characters to jump to the directory I intended. Hopefully the solution can incorporate z itself so it makes use of the frecency metric already recorded by z.

推荐答案

我使用z一次，但是我发现 fasd ，它受到autojump，z或v的启发，我发现更强大，如果我记得很好，那是因为：

I used z once but then I found fasd, which is inspired by autojump, z or v, and which I found much more powerful, if I remember well it is because:

• 它不仅可以查找目录，还可以查找文件


• 它可以 cd 一个结果或使用 mplayer 或您的编辑器或其他命令


• 完成更好，特别是对于zsh（再次，如果我记得很好）。事实是，我经常使用 d 别名来更改目录。

• it not only finds directories but also files
• it can cd a result or use mplayer or your editor or another command
• the completion is better, specially for zsh (again, if I remember well). The thing is, I constantly use the d alias to change directories.

无论如何，还有一个emacs包来查找文件： https://github.com/steckerhalter/emacs-fasd
这很酷，但它不像我想要的那样交互。

Anyway, there's an emacs package to find files with it: https://github.com/steckerhalter/emacs-fasd That's cool, but it isn't as interactive as I would like.

编辑：那么我不得不更新包，并且： / p>

edit: then I had to update the package and:

(setq fasd-enable-initial-prompt nil)  ;; don't ask for first query but fire fuzzy completion straight away.

还有一个未填写的用例：

There's a still a use case that isn't filled:

我经常使用emacs的shell模式。当我使用我最喜欢的别名 d ，它的工作，但我根本没有完成。在这里，zsh的完成明显缺失。所以我想使用ido完成，例如。我写了一个很容易适应z的功能：

I often use emacs' shell-mode. When I use my favorite alias d, it works, but I don't have completion at all. Here, zsh's completion is clearly missing. So I would like to use ido completion, for instance. I wrote a little function which you can easily adapt for z:

编辑：完成命令并添加了TAB触发的ido完成。现在键入 d （d后跟一个空格）。如果它不断变化，如果我设法创建一个小模式，我将发布链接到我的gitlab repo。

edit: finished the command and added ido completion triggered by TAB. Now type d (d followed by a space). If it keeps changing and if I manage to create a minor mode I'll post the link to my gitlab repo.

编辑：我创建此功能的一种模式： https://gitlab.com/emacs-stuff/fasd -shell / tree / master

edit: I created a mode for this feature: https://gitlab.com/emacs-stuff/fasd-shell/tree/master

    ;; Use the fasd command line utility to change recently visited directories and more.

(defun fasd-get-path-list (pattern)
  "call fasd with pattern and return the list of possibilities"
  (s-split "\n" (s-trim (shell-command-to-string (format "fasd -l -R %s" pattern))))
)

(defun fasd ()
  "If current shell command is `d something' call fasd"
  (interactive)
  (let* ((user-input (buffer-substring-no-properties (comint-line-beginning-position)
                                                     (point-max))))
    (if (and (string= (substring user-input 0 2) "d "))  ;; todo: mapping to use something else than d and change directory.
        (progn
          ;; get what is after "d "
          (setq fasd-pattern (buffer-substring-no-properties (+ (comint-line-beginning-position) 2) (point-max)))
          (setq fasd-command (concat "cd " (ido-completing-read "cd to: " (fasd-get-path-list fasd-pattern))))
          (comint-kill-input)
          (insert fasd-command)
          (comint-send-input)
          ))))

;; Use TAB as in normal shell. Now we have even better completion than in zsh !
(define-key shell-mode-map (kbd "<tab>") 'fasd)  ;; works like a charm :)

作为一个附注，我不经常使用它，因为我使用 shell-here 和 shell-pop （一个下拉式终端，如gnome的guake）。

As a side note, I don't use it very often because I open shells in the directory of the current buffer with shell-here and shell-pop (a drop-down terminal like guake for gnome).
