Add syntax highlighting to certain file extensions for VIM or GVIM by default

Question

In my Linux machine files with the .sv extension opens up by default with the verilog syntax highlighting scheme, however extension with .vor .vs don't. I have to manually in gvim do a :set syntax=verilog every time I open one of these files.

How do I make those file extensions .v or .vs open up in a verilog syntax highlighting by default ?

Thanks

Add an auto-command to your .vimrc to do that for you:

autocmd BufNewFile,BufRead *.v,*.vs set syntax=verilog

The "correct" place to put these is in ~/.vim/filetype.vim; see :help new-filetype. (~/.vimrc mostly works, too.) – Barbarism

There are the two lines of though...for me personally it makes more sense to keep these simple configuration settings in .vimrc. – Tartrate

@IngoKarkat In my case, setting the filetype via filetype.vim didn't work because I needed to override a filetype that was already detected correctly but didn't provide syntax highlighting. – Spirograph

autocmd BufNewFile,BufRead *.v,*.sv,*.vs set syntax=verilog (same, but including *.sv) just in case your setup doesn't recognize .sv already – Quadrangular

@IngoKarkat From the :help new-filetype => "In any way, it's better not to modify the $VIMRUNTIME/filetype.vim file. It will be overwritten when installing a new version of Vim." They then suggest to put a file with the autocommand in a folder called ftdetect. Perhaps they updated the help since you commented. – Dodge

@SteakOverflow: The help mentions four ways. Your is referred to as option A, while mine is option C. Both are fine; one is fine-granular, the other keeps everything in one place. I actually use both approaches in parallel :-) – Barbarism
