Working With Rails

Rtex

= RTex Template Engine

A template engine allowing the inclusion of ERB-enabled TeX template files.

The resulting tex is passed through pdflatex and generates a PDF file for the user.

== Example Usage

In the controller, something like:

def mypdf
  @time = Time.now
end

In the view (mypdf.rtex)

\documentclass[10pt]{article}
\begin{document}

The time is <%= @time %>.

\end{document}

The mypdf action will now generate “mypdf.pdf” for the user.

You can use the l (escape_latex) helper, as well:

<%=l @something %>

Configuring

You can configure Rtex by using an @options_for_rtex hash in your controllers.

Here are a few options:

:filename (default: action_name.pdf) Filename of PDF to generate

:debug (default: false) Debugging mode; raises exception with raw latex

:tempdir (default: RAILS_ROOT/tmp) Temporary Directory

:preprocess (default: false) Run through latex first (for TOCs, etc)

:shell_redirect (default: nil) Optional redirection for shell output (set to '> /dev/null 2>&1' on *NIX, perhaps)

Note: If you're using the same settings for @options_for_rtex often, you might want to put your assignment in a before_filter (perhaps overriding :filename, etc in your actions).

Problems

Layouts are currently not supported; for the moment use header and footer partials.
