Converting Word Documents (and other types of files) to PDF in a rails application

[Brendon]

Hi everyone,

I'm currently developing a Rails content management system, and one of
the useful features we're trying to get sorted is a way to allow a
user to upload a word document or some other type of regular file, and
have it converted by the server to PDF.

I've seen a java programme called Alfresco do this using Open Office,
but I'm just wondering if there's another way that's more integrated
with Ruby?

If anyone knows if bits and pieces of tech already exist in this area
but they just haven't been brought together in this way yet, I'd be
keen to learn the names of these projects. Perhaps we can create a
plugin as a result of our larger project.

Looking forward to your ideas

Cheers,

Brendon

There are open source things that kinda sorta almost work, but they're
ephemeral by nature -- Microsoft proprietary formats are ... well ...
proprietary. Abiword and OpenOffice.org can read most Word documents,
and lots of tools can write PDFs. Here's a list of things I have on Gentoo:

I think "wv" is the best of this crowd, but it's been a while since I
had to eat a Word document on my Linux box. As far as Word-to-PDF is
concerned, it's more or less built in to OpenOffice.org, so just
shelling out to that might get the job done. O is quite a memory hog,
though, so you'll probably want to fire it up as a server and leave it
running.

i'd reccomend one of three approaches

1) run windows under cross-over office on a linux box or under parallels on
osx. then you can install ruby, under windows, and write a ruby application
that does this using the native ms bindings

2) setup a windows servers (two would be better) and run a simple drb
service for converting doccuments - again using the native drivers and ruby

3) use some online service such as http://www.zamzar.com/ and drive it via
http libs/curl

if it were me i'd go with 3 since any reliable method will ential keeping a
windows box online (!!). you could could probably write producer code that
posted files to a service and a consumer that checks a special email account
for finished files in a few days...

regards.

Thank you both for your informative replys. I like the idea of an
online service. As I was reading your first two options I quickly came
to your conclusion !

I'll post any learnings and methods on here when I have something
working,

Cheers,

I think the best way might be to use RJB or JRuby and Jakarta
