Re: Problem on generating GRTAGS for vim scripts

[Shigio YAMAGUCHI]

Hello,

No, it isn't. It is a bug.

'pygments-parser.la' works by combining two parsers: Pygments and Ctags.
It seems that the parsers recognize symbols differently.
Ctags picks up symbols with namespace but Pygments do it without namespace.

Ctags           lightline#highlight
Pygments        highlight

> Is there any workaround on this ?

You can pick up both symbols using a regular expression 'highlight$'.
('$' matches the end of the symbol.)

$ global -x 'highlight$'
lightline#highlight  263 autoload/lightline.vim function!
lightline#highlight(...) abort
...

$ global -xrs 'highlight$'
highlight          54 autoload/lightline.vim     autocmd
SessionLoadPost * call lightline#highlight()
highlight          56 autoload/lightline.vim           \ | call
lightline#update() | call lightline#highlight() | endif
...

'global -xr' does not work, since global cannot understand that
'lightline#highlight' and 'highlight' are in a reference relationship.
I think the only way to fix it fundamentally is to rewrite one of the parsers.
