In vim, FIXME and TODO are highlighted, but I can\'t get FIXME: and TODO: (note the colon after the keyword) to highlight? What should I put in my .vimrc to make this happen
If you make your own environment, make syntax file (not .vimrc)
make syntax file (not .vimrc)
global syntax file is located vim directory (ex. /usr/share/vim/vim72/syntax/c.vim)
and if you make ~/.vim/syntax/c.vim, then you can add syntax for your own. (override)
Just add additional syntax in that file. (the way @Jefromi does)
