如何更改目录上的emacs helm-find-file默认操作，使其进入目录而不是直接打开? [英] How can I change emacs helm-find-file default action on directory to be go inside the directory instead of open in in dired?

问题描述

我正在使用emacs前奏.

I am using emacs prelude.

我最近决定从ido转向掌舵.

I recently decided to switch to helm from ido.

所以我在emacs前奏中启用了helm和helm-everywhere，

So I enabled helm and helm-everywhere in emacs prelude,

一切正常，除了helm-find-file

在Ido中，我可以按ret进入所选目录，但是我必须亲自按right或c-j. 同样，helm-find-files将在每个目录的最顶部列出.和... 这意味着在ido中，如果路径上没有很多目录，我可以按ret ret ret直到到达最终目的地.

In Ido, I could hit retto go down the selected directory, but I have to hit right or c-j in helm. Also, helm-find-files would list . and .. at the very top for every directory. This means in ido, I can just hit ret ret ret until I get to the final destination if there aren't many directories along the path.

但是在掌舵中，我必须键入一些字符，按c-j键入至少1个字符，再按c-j，依此类推. 我什至不能连续打c-j.

But in helm, I had to type some chars, hit c-j type at least 1 char, hit c-j and so on. I cannot even hit c-j continuously.

我不想切换回ido，因为我真的很喜欢find文件中的helm的grep功能.

I don't want to switch back to ido because I really love helm's grep feature in find-file.

无论如何，我是否可以更改默认顺序以使它可能在底部列出.和..，并在ret中输入目录而不是打开目录?

Is there anyway I can change the default order to have it maybe list . and .. at the bottom and ret to enter directory instead of open dired?

推荐答案

您要查找的功能是(helm-execute-persistent-action)，默认情况下绑定到C-z.有些人喜欢使用标签切换此设置:

The function you're looking for is (helm-execute-persistent-action), which is bound to C-z by default. Some people like to switch this with tab:

(define-key helm-map (kbd "<tab>") 'helm-execute-persistent-action)
(define-key helm-map (kbd "C-z") 'helm-select-action)

如果愿意，您可以将其绑定到ret，但是它不会按照您期望的方式打开文件.

You can bind it to ret if you like, but it won't open files the way you expect it to.

关于您的其他问题，我不知道头盔是否可以设置默认选择位置，但是要从顶部选择第一项，您可以执行以下操作:

As for your other question, I don't know if helm has a way to set the default selection position, but to select the first item from the top you could do something like this:

(define-key helm-map (kbd "C-j")
  (lambda ()
    (interactive)
    (helm-move-selection-common :where 'edge :direction 'previous)
    (helm-move-selection-common :where 'line :direction 'next)
    (helm-move-selection-common :where 'line :direction 'next)
    (helm-execute-persistent-action)))
