Re: langmap for pygments-parser is case sensitive

Hi,

I have added the required version of pygments in

the following file in the package.

[plugin-factory/PLUGIN_HOWTO.pygments]

                            ============ ADDED

Thanks,

Hi,

> pygments.util.ClassNotFound: no lexer for alias 'awk' found

This is the right behavior because Pygments 1.4 does not have 'awk' lexer.

> It works fine if I change the rule name from "Awk" to "awk"(lower case) in gtags.conf.

In this case actually pygments plugin skips processing the file,
because lower case langname is reserved for gtags's built-in parser.

Thanks,
