1. this is my ~ folder

[lane@vbox ~]$ ls
a.out  auto-commit  critical  lib  mssout  pms_statistics_batch  shell-conf  vs.cpp  vv.cpp

2. jut type vim in terminal, then press <leader>f. this is the output:

   1 .bash_logout
   2 .bash_profile

3. type <c-p>, this is what CtrlP output:

> lib/libapl.pl
> mssout/base64.o
> mssout/mssout.o
> mssout/makefile
> mssout/mCurl.o
> mssout/cJSON.o
> mssout/mssout
> vs.cpp
> vv.cpp
> a.out

I think LeaderF's output is strange. I don't want to see something like .cache/XXXX or .git/XXXX when I press <leader>f. It seems CtrlP's output is more accetpable. Is this a bug? Or just something I haven't set up correctly?

hi, 我就是前几天在知乎评论问问题那个, 今天终于可以把问题详细的整理成issue了. 感觉每次使用<leader>f的时候出来那堆隐藏文件夹下的东西看着挺别扭的, 不知道是刻意为之还是就是有bug? 而且通常情况下, 我文件夹里都会有比如.gitignore文件, 在使用<c-p>的时候他并不会默认显示出来, 但是<leader>f的时候会显示出来. 总感觉这些隐藏文件不显示似乎更符合直觉来着.

这也算是个bug吧，我fix了。
不过你还可以安装rg，这样就可以使用rg来建立索引，会更快。

[zhanglintc]

更新了, 确认了下, 现在 .cache 这样的隐藏文件夹不会出现了, 非常感谢. .gitignore 这样的隐藏文件依然会出现, 不过这个倒不影响, 反正隐藏文件没几个, 显示出来心里还有数一些. 只有隐藏文件夹比较烦人.

rg是什么意思, 就是我按他的记载安装就可以吗, 你这个插件到时候会自动调用rg来提高检索速度呗?

[Yggdroot]

奇怪，我这边.gitignore不会显示出来。
实际上后台执行的是这个命令find "." -name "." -o -name ".*" -prune -o -type f -print 2>/dev/null | sed 's#^\./##'，你确定用这条命令.gitignore还能显示出来？

rg是一个类似grep的工具，但是比较快。只要安装成功（rg这个命令可用），LeaderF就会自动调用rg。

[zhanglintc]

现在我这里是这样的:

1. 以前<leader>f后立即执行:echo g:Lf_Debug_Cmd显示如下:

find "." -name . -o -type f -print 2>/dev/null | sed 's#^\./##'

Shell中执行这句话会出现.git一类的隐藏文件夹, 也会出现.gitignore.

---

2. 现在<leader>f后立即执行:echo g:Lf_Debug_Cmd显示如下:

git ls-files && git ls-files --others --exclude-standard

Shell中执行这句话不会出现.git一类的隐藏文件夹, 但是会出现.gitignore.

---

3. 执行你给出的find "." -name "." -o -name ".*" -prune -o -type f -print 2>/dev/null | sed 's#^\./##'这条命令, 不会出现隐藏文件夹和文件.

---

看起来似乎是没有正确执行到你想要执行的那条命令. 当然我觉得这个好像问题不大来着.

[Yggdroot]

哦，原来如此。
你如果在一个git的repo下运行LeaderF，就会用git ls-files && git ls-files --others --exclude-standard。
具体逻辑在这里：

let g:Lf_UseVersionControlTool = 0可以不使用git。
