Ignore subdirectories

[RobertAudi]

Description

At the moment the NERDTreeIgnore allows to ignore files and directories by matching the last path component:

nerdtree/lib/nerdtree/path.vim

Line 498 in aaa946f

return self.getLastPathComponent(0) =~# pat

So the following will not work:

let NERDTreeIgnore = ['tmp/cache$[[dir]]']

It would be nice if we could specify paths to ignore. Something like that would not change the current behavior (it would just add to it):

let NERDTreeIgnore = ['tmp/cache$[[path]]']

@RobertAudi, You can checkout the branch named i1203. It has your request in it. Give it a try, and let me know how it works for you.

@PhilRunninger I just tried it and it works perfectly.

I was going to say it didn't seem to work, but then I modified the pattern. The problem was that unlike [[file]] and [[dir]] you should't use $ otherwise it only match directories without anything inside.

Anyway, it works perfectly!

@RobertAudi could you tell me a scenario where you'd use this in place of the existing tags? I need some inspiration for the help documentation.

The reason your pattern didn't work with the $ is because I was using the UI-formatted path, which has a trailing forward slash on it, such as /tmp/cache/, which doesn't match the regex /tmp/cache$. I pushed another change to correct that, if you want to give it another go. FYI, the Windows equivalent pattern would need to be specified like so, with escaped backslashes:

let NERDTreeIgnore = ['\\Temp\\cache$[[path]]']

@PhilRunninger I sometimes put temp files in tmp, for example files where I put stuff that I will reuse. However there are often other directories in the tmp directory such as cache or pids that either have huge amount of files and/or unreadable files, and if the directory node is opened it will slow down the whole editor to load its contents in the tree.

Another such example is vendor/cache in Ruby/Rails projects with vendor gems cached by bundler.
