For those using Linux and Vim, here a syntax highlighting file based on cpp.vim. It is not extensively tested but so far it worked OK for me (tested with vim7). It might work on Windows, but I never tested.

Save it to a file name cfdg.vim and place it in $HOME/.vim/syntax directory. Make it active by adding the following lines to your .vimrc (or .gvimrc):

Code: Select all

" syntax for .cfdg files
au BufNewFile,BufRead *.cfdg,*.CFDG	setf cfdg

Cool! But don't forget to add 'background' to cfdgStatement.

True! After some more testing, if everything is OK, I might sent it to Bram Moolenaar for the inclusion in the main Vim distribution.

After some thinking, I suppose there is no need for a linux graphics version. I use Vim to edit cfdg file, command line to call the interpreter, and kview to diaplay automatically reload the image, once it updates on disk.

Before you send it to Bram Moolenaar please add the tile statement. This is a new statement in Context Free 2.1beta (which I just posted).
