counsel-ag使用问题

Emacs-general
1

对于counsel-ag，有两个问题想问一下：

1，必须输入3个字符才能够搜索，这个可以设置吗，比如两个或者1个。

2，有没有类似helm-ag的功能，可以指定搜索的起始目录。

2 
(defun counsel-ag-function (string base-cmd extra-ag-args)
  "Grep in the current directory for STRING using BASE-CMD.
If non-nil, append EXTRA-AG-ARGS to BASE-CMD."
  (when (null extra-ag-args)
    (setq extra-ag-args ""))
  (if (< (length string) 3)
      (counsel-more-chars 3)
    (let ((default-directory (ivy-state-directory ivy-last))
          (regex (counsel-unquote-regex-parens
                  (setq ivy--old-re
                        (ivy--regex string)))))
      (let* ((args-end (string-match " -- " extra-ag-args))
             (file (if args-end
                       (substring-no-properties extra-ag-args (+ args-end 3))
                     ""))
             (extra-ag-args (if args-end
                                (substring-no-properties extra-ag-args 0 args-end)
                              extra-ag-args))
             (ag-cmd (format base-cmd
                             (concat extra-ag-args
                                     " -- "
                                     (shell-quote-argument regex)
                                     file))))
        (counsel--async-command ag-cmd)
        nil))))

这里的 cousel-more-chars 写死的是3，你如果想修改，可以自己去修改源码，作者貌似并没有提供 customize的选项，你可以去作者的 github repo 提issue。

  1. helm-ag 指定搜索目录是指 -G 后面跟的选项么？

输入helm-ag命令后，编辑器底部会显示一个路径，默认是当前路径，你输入Enter后便选择了起始搜索路径，然后输入需要查找的内容，counsel-ag则直接输入查找的内容，没有指定路径的步骤。

4

不想要三个字母，后面输入空格补上就可以了。 想要指定目录 ctrl+u 然后再使用counsel-ag就可以了

多谢，ctrl-u调用的哪个命令，不好意思我用的evil，ctrl-u是个prefix

6

SPC u.

给abo-abo 提个 issue？

1，必须输入3个字符才能够搜索，这个可以设置吗，比如两个或者1个。

补空格不行，空格也会被当成搜索关键字。

昨天给 abo-abo 提了一个 issue，他已经解决了，现在可以通过 counsel-more-chars-alist 来设置了。 详见： Add an option for length for `counsel-more-chars`? · Issue #1663 · abo-abo/swiper · GitHub

我默认是使用vmacs-counsel-rg这个命令来启用rg 在当前目录下搜索，

如果想搜当前symbol,就使用C-.

如果想切换到git. root目录，就用C-;

C-o 或者 C-uC-; 则会让你选择目录

如果想向上层目录就C-l或C-h，基本满足我的需要，

另外也可以先切到对应的dired 再执行此命令 至于如果快速切换到想去的dired ,这是另一个话题 可以 package-install:ivy-dired-history GitHub - jixiuf/ivy-dired-history

如果想实现helm-grep-do-grep. 那样 “foo !bar” 搜索foo ,但是过滤掉bar 则 (setq counsel-rg-base-command "~/.emacs.d/bin/rgwrapper -z %s ") ;这是用go 写的对rg的简单包装 https://github.com/jixiuf/vmacs/blob/master/bin/rgwrapper.go

[search-ag失效并提示Symbol’s function definition is void: counsel-more-chars]

(search-ag失效并提示Symbol’s function definition is void: counsel-more-chars)

我用Windows10下的Spacemacs 0.200.13 master版本，search-ag或者search-project-ag都不能使用，并提示if: Symbol’s function definition is void: counsel-more-chars ，本人小白，您方便具体说一下怎么解决吗？谢谢~

我不用spacemacs 你可以看下下载下来的包是什么版本的 试着更新一下看看
