== Description

rails-latex is a renderer for rails 3 which allows tex files with erb to be turned into an inline pdf.

== Synopsis

app/helpers/application_helper.rb:
   def lesc(text)
     LatexToPdf.escape_latex(text)
   end

app/views/stories/show.html.erb:
   ...
   <%= link_to "print", story_path(@story,:format => :pdf) %>


app/views/stories/show.pdf.erb:
   ...   
   <%= lesc @story.name % >

app/views/layouts/application.pdf.erbtex:
   \documentclass[12pt,a4paper,sloppy,< %= @landscape % >]{article}
   ...
   < %= yield % >
   \end{document}


config/initializers/mime_types.rb:
   ...     
   Mime::Type.register "application/pdf", :pdf, ['text/pdf'], ['pdf']


Only the file containing the \\documentclass should be of type: .pdf.erbtex . Partials and views (when there is a layout)
should be of type .pdf.erb .

If a LaTeX package requires two parses then add the following to the .pdf.erbtex file:

   <% @latex_parse_twice=true %>

See the rails application under examples/rails-latex-demo/ for a working example.
