崇高的文本2的“Goto Anything” （或即时搜索）Emacs？ [英] Sublime Text 2's "Goto Anything" (or instant search) for Emacs?

问题描述

我最近尝试了崇高的文字2 ，我发现 Goto Anything 对导航源代码非常有用（ Ctrl-P文件@符号似乎工作得很好）。 Emacs有什么类似的东西吗？最好的东西，只是工作，没有一吨的自定义elisp。

I tried out Sublime Text 2 recently, and I found Goto Anything superbly useful for navigating source code (Ctrl-P file@symbol seems to work really well). Is there something similar for Emacs? Preferably something that just works, without a ton of custom elisp.

我到目前为止尝试过：

1. 我看过 Helm 和任何，，但据我所知，他们都不能实际的即时搜索

1. I've seen Helm and Anything, but as far as I understand neither of them is capable of actual "instant" search (see edit below).

我已经使用了 多重匹配缓冲区 ，但它似乎也无法满足即时标准。

I've used multi-occur-in-matching-buffers, but it too seems unable to satisfy the "instant" criterion.

imenu / idomenu 适用于单个文件，但不能跨文件运行。

imenu / idomenu works well for single files, but doesn't work across files.

我目前使用＃2和＃3，作为Goto Anything的一个糟糕的替代品。

I currently use #2 and #3 together, as a poor substitute for Goto Anything.

如果不是一个确切的克隆Goto Anything，那么我可以做一个天真的即时搜索解决方案（一个在所有打开的缓冲区中搜索给定的字符串并动态显示结果）。所以这也是可以接受的。

If not an exact clone of Goto Anything, then I could make do with a naive instant search solution (one that searches for a given string across all open buffers and displays results dynamically). So that's acceptable too.

我使用Emacs 24.2，所以任何v24-only elisp也是可以的。

I use Emacs 24.2, so any v24-only elisp is also fine.

编辑：我给了Helm另一个镜头，在 event_jr的建议，我发现它 支持在所有打开的缓冲区中即时搜索。 helm-multi-occur + helm-follow-mode 令人惊讶地接近满足我的需求，唯一的小问题是（有风险的挑剔）：

EDIT: I gave Helm another shot, at event_jr's suggestion, and I found that it does support instant searching across all open buffers. helm-multi-occur + helm-follow-mode comes surprisingly close to meeting my needs, the only minor issues being (at the risk of sounding nit-picky):

• 我还没有找到打开方式code> helm-follow-mode 自动当我运行 helm-multi-occur 。我必须用 C-c C-f 手动调用它。任何人都可以用一个elisp的片段来拍摄它？（见下面的编辑＃2）

• I haven't found a way to turn on helm-follow-mode automatically when I run helm-multi-occur. I have to invoke it manually with C-c C-f. Anyone care to take a shot at this with a snippet of elisp? (see edit #2 below)

它不是聪明像ST2的Goto Anything（即它不明白源代码中的符号，如Goto Anything）。

it isn't "intelligent" like ST2's Goto Anything (i.e., it doesn't understand "symbols" in source code, like Goto Anything does).

编辑＃2 ：现在我有大部分Goto Anything，感谢 event_jr的下面的答案（当然，感谢Helm的创建者， Thierry Volpiatto ）。我衷心地向任何寻找类似功能的人推荐。以下是我目前使用的elisp：

EDIT #2: Now I've got most of Goto Anything, thanks to event_jr's answer below (and of course, thanks to Helm's creator, Thierry Volpiatto). I recommend it heartily to anyone looking for a similar feature. Below is the elisp I'm currently using:

;; instant recursive grep on a directory with helm
(defun instant-rgrep-using-helm ()
  "Recursive grep in a directory."
  (interactive)
  (let ((helm-after-initialize-hook #'helm-follow-mode))
    (helm-do-grep)))


;; instant search across all buffers with helm
(defun instant-search-using-helm ()
  "Multi-occur in all buffers backed by files."
  (interactive)
  (let ((helm-after-initialize-hook #'helm-follow-mode))
    (helm-multi-occur
     (delq nil
           (mapcar (lambda (b)
                     (when (buffer-file-name b) (buffer-name b)))
                   (buffer-list))))))

;; set keybindings
(global-set-key (kbd "C-M-s") 'instant-search-using-helm)
(global-set-key (kbd "C-M-S-s") 'helm-resume)
(global-set-key (kbd "C-M-g") 'instant-rgrep-using-helm)

推荐答案

只需使用掌舵。

它可能比您要求的更多配置，但一旦得到
配置你喜欢什么，应该很舒服。非常喜欢Emacs
;）。

Just use helm.

It is perhaps more configuration than you asked for, but once you get it configured how you like, it should be quite comfortable. Very much like Emacs ;).

你应该向Thierry提交一个bug，以获得更多新手的
默认值。他的问题相当敏感。

And you should file a bug with Thierry for getting some more newbie friendly defaults. He is quite responsive with issues.

主要是多缓冲区互动发生通过
helm-multi-occur 提供。如果您执行该命令，您会注意到您有
首先选择一些缓冲区（使用 C-SPC 从列表中选择
M-SPC 选择全部）。然后，您可以在下一个
提示符下输入查询。很容易使自己的版本跳过缓冲区选择
，如下所示：

Primarily multi-buffer interactive "occur" is provided through helm-multi-occur. If you execute the command, you'll notice that you have to pick some buffers first (use C-SPC to select from the list, M-SPC to select all). Then you can enter your query at the next prompt. It's easy to make your own version that skips the buffer selection like so:

(eval-after-load "helm-regexp"
    '(setq helm-source-moccur
           (helm-make-source "Moccur"
               'helm-source-multi-occur :follow 1)))

(defun my-helm-multi-all ()
  "multi-occur in all buffers backed by files."
  (interactive)
  (helm-multi-occur
   (delq nil
         (mapcar (lambda (b)
                   (when (buffer-file-name b) (buffer-name b)))
                 (buffer-list)))))

helm-buffers-list

通常，您不关心查询字符串的确切事件，但需要包含所有缓冲区的
列表。

helm-buffers-list

Often you don't care about the exact occurrences of the query string, but want a list of all buffers that contain it.

helm-buffers-list 有一些技巧。
指定的第一个符号是按主要模式进行过滤，您可以使用@前缀将
的列表缩小到包含字符串的缓冲区。

helm-buffers-list has some tricks up its sleeve. The first symbol you specify is filtering by major-mode, and you can use the "@" prefix to narrow the list to buffers that contain a string.

为了方便起见，ruby @prompt将显示一个缓冲区的列表，其主要模式
包含ruby，其内容包含prompt。或者您可以使用@prompt显示包含提示的所有缓冲区。

To wit, "ruby @prompt" will show you a list of buffers whose major-mode contains "ruby" and whose contents contains "prompt". Or you can just use "@prompt" to show all buffers that contain "prompt".

编辑修改 my-helm-多个全部启用舵手跟随模式。

EDIT modified my-helm-multi-all to enable helm-follow-mode.
