Re: extracting tags like vim help

Hi,
Maybe I messup things.
I want to extract tags in my documents. Tags are present in the format the vim help files are.

Example
*tag1* *tag2*

Here, there is two options to extract the tags and I have tested both of them.
1. :helptags. It is a vim built-in function to extract the tags but only works for ".txt" and ".??x" file extensions.
My files do not have that extension so I can't use it. I have searched for an option to change but I haven't found it.

2. ctags. It does not have language support for vim help. It does vim language but It is for vim script. I have created an extension to the language with this content (I call my new language MAN)

--langdef=MAN
--language-force=MAN
--regex-MAN=/\*([^\.\*][^\*]*)\*/\1/

This works fine. Extract the tags inside starts. But there is a problem with several tags in the same line. For this issue I put the C example. Not because I want to use ctags to extract C tags but because ctags can extract several C tags in the same line.

Regards,
Javier
