Re: Problem on generating GRTAGS for vim scripts

Thanks Shigio-san for clarifying the problem in detail.

I agree.

I personally think this is the problem on Pygments. So, would like to try to 
dug into it.

Is there any way to make pygments generate the symbol ?

Following command generated highlighted text.
$python3 -m pygments plugin/lightline.vim

I am wondering if there is any option to generate symbol only...
In other words, how pygments-parser get the symbol from pygments...
