All,
Re the article here:
[http://groups.google.com/group/django-
users/browse_frm/thread/2f254591d5d84340/5ad372019ee0c3c6?lnk=gst&q=custom+filters&rnum=1#5ad372019ee0c3c6

(ignoring the digression about email subject lines!)
I put forward the need for a simple way to have filters and tags that I
define in my local script automatically available to DJango, without the
need for a package import, or a specific 'template' package within my
source tree.
I have attached a page of 4 lines (+ documentation) that enables this with
the class BuiltinLibrary. Using the class is as follows:
{{{
def filter_rst_h1(value, arg='-'):
"Write a single underline under the text"
line=arg * len(value)
return "%s\n%s" % (value, line)
from django.template import ``BuiltinLibrary`` # <-- NEW!
# set up extra library of routines for later use...
library = BuiltinLibrary()
library.filter('filter_rst_h1', filter_rst_h1)
}}}
The patch and a full, standalone demonstration program is attached.
Thanks for considering this patch...
A.J.E.
