Font Module
Reported by TomasC | July 21st, 2008 @ 11:34 PM
Hi guys,
tried to used prawn on a Rails project (together with prawn_view http://github.com/thorny-sun/pra... and run into a clash with Font module.
My app has a model called Font. After installing prawn, any controller using my Font model throws "undefined method `find' for Font:Module". Not exactly sure why.
Any suggestions?
Thanks,
T
P.S. greeting to New Haven -- I moved out at the end of June -- finally! ;-)

Hi Tomas,
This is because Prawn vendors the Font::TTF library, which defines a top level Font module. If you set up a namespace for your model, you can avoid this problem.

Hey Greg,
thanks for prompt reply.
Well I guess that's a solution ... yet ... couldn't prawn be completely encapsulated in its own namespace?

Prawn is. That is to say, all of the code we have written is within the Prawn namespace.
Font::TTF is a separate package which has its own namespace (Font), which your model is clashing with.
I could move Font::TTF into the Prawn namespace but that'd really be overstepping boundarys, IMO. We aren't maintaining Font::TTF, and we want all the necessary praise / blame to go back to the original author of that library.
Font::TTF is a dependency, if that helps clarify things. It's only vendored in Prawn for convenience, you'd have the same problem if we depended on a gem of it.

Understand, that makes sense.
I have two questions if I may ask:
- is there a way to implement support for OTF fonts?
- is there a way to 'outline' all text so the pdf does no longer contain the embeded font file but is rather a set of curves (outlines)?
