Issue: #25 (comment)

[neobundle] Uncaught error while sourcing "color_coded": Vim(execute):E121: Undefined variable: b:current_syntax in function color_coded#enter, line 7

Here is the profile.log and vim version here from the error: https://gist.github.com/tony/a23eb36f188102120df6

Will follow up on what plugin / scheme is causing this issue and the workaround.

Hi,

I just tried to install color_coded on my machine (archlinux) and have the same error.
Small warning though, i'm very new to vim! So just in case, here are the steps i did to install this:

1. install vim
2. install vundle according to the github page (not via the archlinux packages since there is none)
3. install color_coded and following the vundle docs, followed by the "all" section.
4. then i also added the two config options to my .vimrc which are described under the "Options" section (the two let ... variables).

So now vim is setup, vundle is done, color_coded is done. Thus i open a cpp file. Then i get these errors:
Error detected while processing function color_coded#enter:
line 7:

then the file opens with a very small bit of highlighting. Definitely not as shown in the screenshots :)
Toggling color_coded and executing :colorscheme twilighted doen't seem to help.

I'm not sure if the errors i mentioned come from the .so file, a lua file or a python file. In case it;s python, the version i use there is 3.4.3.

If you need more info? I'd be happy to try it out. Also, testing possible patches you might have won't be a problem.

[UnrealQuester]

Do you have syntax on in your vimrc? This is needed by color_coded to do highlighting. Seems like this is not documented.

I've been able to reproduce this issue by using NeoBundle and lazy loading color_coded, as per the color_coded example in the README:

  NeoBundleLazy 'jeaye/color_coded', {
      \ 'build': {
      \   'unix': 'cmake . && make && make install',
      \ },
      \ 'autoload' : { 'filetypes' : ['c', 'cpp', 'objc', 'objcpp'] },
      \ 'build_commands' : ['cmake', 'make']
  \}

For now, the solution it to eagerly load color_coded; I'm looking into what the actual issue is.

[jeaye]

I've created an issue on neobundle's repo to hopefully get some more information about this.

[jeaye]

I've resolved this issue on the revamp branch, which I'm currently use to spice color_coded up with a number of fixes. The commit is 7b923cc and I encourage you all to give this a shot with neobundle's lazy loading.
