You need to put the pygments module in web2py/site-package or (if you
use the web2py source distribution) install it normally under python
with
easy_install pygments
Some modules can be installed under applications/yourapp/modules/ but
not all. The reason for this special folder is to allow apps to
include some modules and bypass the python sys.path import mechanism
to avoid conflicts with existing modules. For this we use local_import
instead of import. This works only if the module being imported itself
does not rely on sys.path. Pygments does. It assumes there is only one
instance of pygments in a location listed in sys.path. This prevents
two apps within web2py to have two different copies of pygments and
breaks the import mechanism.
Anyway. web2py has syntax highliting:
{{=CODE(code,language='html')}}
language can be 'web2py','html','python','cpp' and 'java'. It is not
as flexible as pygments and has less options but gets the job done.
