Dear all, attached you will find a new VIM syntax highlighting file for Chuck files (thus for files like filename.ck ) In your .vimrc you can specify a color for each of the following labels: Statement, Operator, Repeat, String, Conditional, Comment, Special, Statement, Type, Structure, Boolean and Include in the following manner: highlight comment ctermfg=DarkGreen or you can also use any of the great vim coloring files, which will do this job for you. I hope it is useful to people as it is to me, and please, if you have any good/bad comments don't hesitate contacting me. Eduard
