Hi guys,

## R-Pass

R-Pass (the Ruby Presentation Assistant) is a bundle of small utilities  
and  
configuration files to assist you when writing talk slides and when  
giving  
talks and demos. The main utility is a small text filter, based on  
CodeRay,  
that highlights code in all the CodeRay supported languages, for slides  
written in S5/HTML and LaTeX (you’ll need my CodeRay extensions for the  
latter, though). R-Pass comes with ready-to-use configuration files to  
integrate the highlighter with VIM.

## Why?

```
I give talks and demos from time to time. I use LaTeX a lot 

```

(specifically,  
LaTeX-Beamer), and I wanted to highlight all the sample Ruby code in the  
slides. Once I found some Makefile-based solution (can’t recall where),  
but I  
didn’t like it very much, so I decided to write my own generic simple  
text  
filter to highlight code.

```
Once I wrote it, I figured out it was a good idea to write a couple 

```

of  
tiny utilities and configuration files to assist myself when giving or  
writing  
talks… and I bundled them together and decided to open up a project at  
RubyForge to release them. Although I opened it a week ago or so, I have  
just  
released the first “stable” version:

```
http://rubyforge.org/frs/shownotes.php?release_id=7051

```

## Example

Say you have some LaTeX slides open in VIM, and you need to write some  
sample  
code. You write it this way:

## ------------------------------------- 8\<

## %code ruby % class Something % attr\_reader :foo % attr\_accessor :bar % def hello % puts “Hello!” % end % end %endcode ------------------------------------- \>8

Then, you hit “\RH” (for “Refresh Highlighting”) in VIM, and you get:

## ------------------------------------- 8\<

%code ruby  
% class Something  
% attr\_reader :foo  
% attr\_accessor :bar  
% def hello  
% puts “Hello!”  
% end  
% end  
\begin{semiverbatim}  
\synreserved{class} \synclass{Something}  
\synident{attr\_reader} \synsymbol{:foo}  
\synident{attr\_accessor} \synsymbol{:bar}  
\synreserved{def} \synmethod{hello}  
\synident{puts}  
\synstring{\syndelimiter{“{}}\syncontent{Hello!}\syndelimiter{”{}}}  
\synreserved{end}  
\synreserved{end}

## \end{semiverbatim} %endcode ------------------------------------- \>8

## Links

The project is registered in RubyForge, as “r-pass”, so you have:

```
Homepage: http://r-pass.rubyforge.org/
Download: http://rubyforge.org/frs/?group_id=2223
RubyForge homepage: http://rubyforge.org/projects/r-pass

```

The code is in Darcs, at [http://www.demiurgo.org/darcs/r-pass/](http://www.demiurgo.org/darcs/r-pass/) , so  
getting it is a matter of:

```
darcs get http://www.demiurgo.org/darcs/r-pass/

```

Enjoy!
