Undefined variable: b:node_root

[FuzzOli87]

Hello!

I've been using Deoplete with Deoplete-tern. There has been a consistent error message when I'm working on some projects. The projects are those that use the require() import instead of the new import statement. Is there any chance this is an issue related to this plugin?

It is related in some way... I am getting also this some times I think is on gather_results but I couldn't find how this happens.

But reading your traceback looks like now it is related with tag files when tries to gather_results on it.

@carlitux Do you by any chance have neoinclude.vim installed?

[carlitux]

@FuzzOli87 yes I have installed.

[FuzzOli87]

@carlitux That is the source of the issue. I'm not exactly sure what the plugin is meant to do, I don't even remember why I installed it. I looked it up in the deoplete docs and it was a recommended install so I added it. I know, lazy.

Anyways, I removed it and it stopped the errors. Not sure what the cause is but I might go back and investigate further. I don't get those errors when I'm using ES6 modules though, at least not that I remember.

It sounds like neoinclude.vim is for "include" files. I thought it meant stuff like import/require files? The only language I can think of that "includes" is C.

[carlitux]

That could be... anyway I reported the issue and it will be fixed soon.
