Re: Syntax Highlighting

[Russell Fiedler <fiedler@xxxxxxxxxxxxxxx>]

======================
In a similar vain to those who wanted an emacs mode for ferret, I wonder
if anyone has developed a file for ferret to be used with the Syntax
highlighting included in the VIM (Vi IMproved) package. Any help
appreciated,
======================

Ask and ye shall receive! I'll also place it on our ftp site at
ftp.hba.marine.csiro.au under pub/fiedler/ferret

I haven't spent a lot of time on it but it does a pretty reasonable job.

Any changes/enhancements that people wish to submit will be gratefully
received.

Cheers,
Russ
