Well, first read http://swish-e.org/current/docs/Filter.html
that should give some overview. Then just pick an existing filter and
copy it as your new filter.
You can put the filters anyplace, they just need to be in the
SWISH::Filters name space. It's not as complex as it sounds --
SWISH::Filter (SWISH/Filter.pm) takes perl @INC array and appends each
path with "SWISH/Filters" to make a full path to a directory. It
think looks in that directory for filters.
So, you can make a file called $HOME/SWISH/Filters and add a module
called PowerPoint.pm to it (the module is SWISH::Filters::PowerPoint)
and then set PERL5LIB=$HOME and SWISH::Filter will find the module.
That make any sense? SWISH::Filter uses @INC to find the filters.

MIME::Type shouldn't be required -- it's just used if available to map
from file extensions to content-types. There's a few built in maps if
MIME::Types isn't installed. But PowerPoint is not in there by

Ok, so that filter found "catdoc" so it's available.

For some reason Doc2txt didn't accept the file for filtering.
What SWISH::Filter does is pass the document to all filters,
one-by-one until it's accepted by a filter. It's up to the filter to
determine if it can filter the document -- normally by checking the
It MAY be that Doc2txt doesn't know about that content type. I think
at one point it only checked for application/msword and then
MIME::Types was updated for x-msword. But I'm not sure. Just look at
Doc2txt.pm and see what it does.
moseley@bumby:~/swish-e/filters/SWISH/Filters$ fgrep msword Doc2txt.pm
return unless $filter->content_type =~ m!application/(x-)?msword!;
So the filter is just returning if the content type doesn't match.
