Nerdtree: Add option to ignore files in VCS ignore file (.gitignore)

[razor-x]

See the gitignore plugin, which removes files in .gitignore from vim auto complete.

Ideally, NERD tree would read ~/.gitignore_global and any .gitignore file in the current tree root and use this along with whatever is set in NERDTreeIgnore to hide ignored files.

reading the svn ignore list if inside an svn checkout would be cool too.

Gentlemen,

I have added an API to add custom path filters. In the add_path_filter_api branch here 64a9579c11b63e2fe0242d45ca12455a7a7d2833

I have also created a minimal gitignore filter here: https://gist.github.com/scrooloose/0cdccd1171891caf0e24. This is just a proof of concept really. There are several things missing:

• We only check for a .gitignore in the nerdtree root
• We cache the .gitignore content forever - so you have to restart vim if you edit the gitignore file
• ...

The filter takes a .gitignore and converts it into a regex to match filenames against. It is highly possible that there are cases/syntax that I'm not handling.

Checkout that branch, and chuck that gist file in ~/.vim/nerdtree_plugin/gitignore_filter.vim. Let me know how it goes.

Disclaimer: Its saturday night and I wrote all this code while drinking rum

You have an implementation on

https://github.com/scrooloose/nerdtree/pull/443

about ignore files untouched

Adding another evaluator tied to "ignore" event you can ignore files ignored by .gititgnore, .git/info/exclude or whatever.

Indeed, is the next evaluator I'm thinking to implement.

To go further, maybe FileFilter toggle can be refined to activate/deactivate evaluators

• (fs) toggle filter status
• (fe) toggle filter exclusions

"s" and "e" will be part of evaluator definition passed on AddEvaluator()

@albfan I am confused. Did you see my comment above yours? We have done almost the same work. I have merged the branch mentioned above into master.

In my comment I also made a start on a gitignore filter. Feel free to take this - this filter is not something I plan to use so I'm probably not the best to maintain it.

I have not made a distinction between path filters (which are what you called Evaluators) and the NERDTreeIgnore option - i.e. the f mapping will disable/enable both.

[albfan]

It was simply a slightly different approach, but it is easily converted to your work. Now it is on master I will rework both plugins (ignore and status)

[albfan]

You can see toggle shorcuts for ignore filters in action in #447. If not defined It simply works as you say

Since this issue is closed, and it looks like @scrooloose merged the functionality based on his comments above, how do you enable the feature in NERDTree?

[albfan]

Opps! All my comments refer to rebased code non existing anymore.

To answer @nhooey, this functionality is for internal NERDTree API. It is intented for thirdparty nerdtree plugins.

e.g: If you can ignore custom keymapping help:

https://github.com/albfan/nerdtree/commit/e9b690723b942db378d3a53b455f37db442b09b0

Here is an working implementation:
https://github.com/albfan/nerdtree-git-plugin/commit/b86c11e8c4adc4e40fa444c21fe3b07075b7b351

which toggle ignore:

• git exclude files
• git ignore files
• git untouched files

Try it with Vundle:

Plugin albfan/nerdtree
Plugin albfan/nerdtree-git-plugin

+1 @albfan — you are a lifesaver!

[albfan]

Good to know! I can't live without hide untouched files on NERDTree.

[stites]

Same here. That's been one of my vim killers!
