Syntax highlight loss in nerdtree when opening fortran files about nerdtree HOT 11 CLOSED

hmm, i havent been able to reproduce this. Which version of vim are you running? and do you have any extra plugins etc for fortran?

Getting the exact same problem with PHP files

I've run into the same error when editing PHP files, I haven't been able to reproduce it reliably but it does happen often.

I get the same issues when opening a php file for the first time on load

from nerdtree.

I also get that the first file I open (php) it's also setting "setlocal nowrap" but then I open another file and it doesn't use that; It uses the "set wrap" I have in my .vimrc

same problem with php...

I was having the same problem with .py files (when a python file opened, NERDTree would lose its color) so I had a wade through my .vimrc.

I had this line:
autocmd BufRead,BufNewFile *.py syntax on

(I picked it up from someone elses config.) I commented it and it fixed the issue.

Nice unculture, that makes sense. According to :help syntax-on, :syntax on sources $VIMRUNTIME/syntax/syntax.vim which removes all syntax rules (including that of nerdtree/taglist/bufexplorer/etc) and then sets up the rules again.

To see what i mean, try :syntax in a nerdtree buffer, then go :syntax on, then look at :syntax again.

The syntax rules for explorer plugins like nerdtree are usually set up in a function in the plugin script itself which vim doesnt know anything about - so it re-setup the rules when :syntax on is called.

@scrooloose , your instructions on Feb 7, 2011 don't show any change in the syntax. Has vim behavior changed, or is there something now in NERDTree to reestablish its syntax highlighting? I think we can close this one.

from nerdtree.

Yes good point. We can reopen this if it is reported again.

I have the same issue with JavaScript files on MacOS (10.12.6), vim version 8.0.666, no problem on Ubuntu. Syntax coloring works just fine when I open files via vim, but files are completely white if I open them with NERDTree. :set syntax=js doesn't work on files opened with NERDTree.
