Giacomo Grasso's awesome vim syntax file for MCNP, with some minor tweaking and also some influence from Seth Johnson's version (found at http://reference-man.blogspot.com/2009/02/mcnp-syntax-highlighting-in-vim.html).

Installation

Because this script comes with a scripts.vim file, I highly recommend using Pathogen for activation and installation so that you can avoid overwriting any existing ~/.vim/scripts.vim file:

cd ~/.vim/bundle
git clone git://github.com/g2boojum/vim-mcnp.git

Alternatively, you can just use vim-plug and put "Plug 'g2boojum/vim-mcnp'" in your .vimrc file.

Please make sure that the following options are set in your vimrc:

syntax on
filetype plugin indent on

Usage

Well, it might just work. The scripts.vim file looks to see if the second line of the file is a comment line, and if the file hasn't already had a filetype assigned, then it turns on the mcnp syntax highlighting. Both false positives and false negatives are possible.

Giacomo Grasso uses ".imcnp" as a file extension for MCNP input decks, so the ftdetect file will turn on the mcnp syntax highlighting for any file with that file extension.

Alternatively, you can do it the old fashioned way:

set ft=mcnp

Development

Pull requests and patches are strongly encouraged!

This code works well enough for me, and well enough for Giacomo, that there really hasn't been much in the way of updates in a very long time. If you'd like to see it do more, please feel free to help!
