Re: Indexing c/c++ comments and text files

[Michael Sullivan]

I only cited id-utils in my first message so that you could see an example 
where another tags system had a capability that appears to be missing natively 
in global.  However, I'm not actually trying to generate an id-utils database 
-- I consider the gtags/global database, tools, and output to be superior.

Instead, I have two different problems that can be potentially solved in 
different ways:

Comments
--------
Comments in files parsed by the c/c++ parser (as identified in the langmap) are 
ignored.  I'm wondering if it would be possible to add a command line option to 
not skip the symbols in comments.

Text Files
----------
Text files that potentially contain useful things to search for (e.g. MIB 
files) don't appear to have a parser (as identified in the langmap).  I'm 
wondering if it would be possible to add a text parser that could be used to 
simply index every word in those files.
