emacs - 如何使子目录中的查找文件搜索 [英] emacs - how to make find-file search in subdirectories

问题描述

我想实现像Emacs那样的Resharper的Go To File功能。当您按下提到的快捷方式时，Resharper会弹出一个接受通配符字符串的文本框，并显示一个自动填充菜单，其中列出项目中与该通配符相匹配的所有文件：

I'd like to implement something like Resharper's "Go To File" feature for Emacs. When one presses mentioned shortcut, Resharper pops a text box that accepts a wildcard string and displays an autocompletion menu that lists all files in a project that match that wildcard:

现在，我知道一个粗暴的方法实现一些或多或少相同的东西。它涉及使用 -lR 运行 dired ，然后调用 dired-isearch-filenames - 将在某个根目录下的文件的整个层次结构上开始增量搜索。

For now, I know a crude way to achieve something more or less equivalent. It involves running dired with -lR and then invoking dired-isearch-filenames - that will start incremental search over the entire hierarchy of files inside certain root directory.

upd。我也知道可以打开缓冲区的负载，将它们全部保存在内存中，并使用 switch-to-buffer 。这个解决方案可以很好地与 ido 一起工作，尽管它不是100％防弹（如果有些文件被添加或删除了？它也不适用于 tabbar ，因为选项卡将显示项目中包含的所有文件，而不是表示我当前上下文的项目的子集。

upd. I'm also aware about the option of opening loads of buffers, keeping them all in memory and using switch-to-buffer. This solution works nicely with ido, though it isn't 100% bullet-proof (what if some files get added or deleted?). It also doesn't play well with tabbar, since tabs will display all the files that are included in the project, but not a subset of the project that represents my current context.

但是，这显示了大量不必要的信息，并且缺少自动完成。我看了一下 ido 和冰柱，但是它们似乎只是在当前目录中。有没有Emacs插件可以帮助我实现我的目标？

However, this shows lots of unnecessary information and lacks autocompletion. I've taken a look at ido and icicles, but they seem to work shallowly, only within current directory. Is there a Emacs plugin that will help me to achieve my goal?

推荐答案

尽管你可能不想保持大量的缓冲区您可以将IDO挂钩到 recentf 中，跟踪最近打开的文件：

Although you might not want to keep lots of buffers open, you can hook IDO into recentf, which tracks recently-opened files:

(recentf-mode 1)
(setq recentf-max-saved-items 300)

(defun ido-choose-from-recentf ()
  "Use ido to select a recently opened file from the `recentf-list'"
  (interactive)
  (find-file (ido-completing-read "Open file: " recentf-list nil t)))

(global-set-key [(meta f11)] 'ido-choose-from-recentf)

我一直在使用这个技巧，这是我需要的所有文件切换的99％。

I've been using this trick for years, and it's 99% of all the file-switching I need.

除此之外，我使用 Mx rgrep ，您可能还要查看 Mx find-dired 和 Mx find-grep dired 。

Beyond that, I use M-x rgrep, and you might also like to look at M-x find-dired and M-x find-grep-dired.
