Fortran Syntax Highlighting

[GoogleCodeExporter]

How hard would it be to do syntax highlighting for Fortran F90/F95 source code?

I have a google code project with mostly Fortran source code and syntax
highlighting would be nice.

I have attached a syntax highlighting file for F90 for test editor, textpad 
http://www.textpad.com/ 

as an example

I forget to say, if you could let me if it would be possible, I could try and 
do it
myself.

http://eli-project.sourceforge.net/fortran_html/Parse.html has a very large 
grammar
for Fortran 90.

If you want to take a stab, you can look at the lang-*.js files in the src 
directory.
 I'd start with a language that is lexically similar to Fortran 90 and go from there.

I tried to use lang-*.js as a template but have run across the following 
problem :-

Fortran 77 reserves the first 7 characters of every line for special 
instructions such as 
comment indicators or continuations & or goto labels. 

I don't see an easy way of indicating those in the lang-*.js. Any suggestions?

How can I use the file you attached, since it does not seem to be included in 
prettify yet?

I figured it out, sorry for the spam. 

    <script src='path/to/lang-fortran.js'/>

But why is this not included? It works fine for my code.

how and whre could I edit to keep highlighting keywords folowing the comma 
punctuation?

ie:   real, dimension
      integer, allocatable 

Thanks for the help.
