Vim Commands and mapping

Question

Hi I am trying to make a VIM mapping to run a script when I press F2. I am struggle to get a full path for the file that is being edited with vim into the command function.

nnoremap <F2> :! php /home/kbuczynski/diff_re.php fix <full file path here> flagArg

Any idea ?

Answer 1

You can get the full path to the current buffer with:

expand('%:p')

Your mapping could look something like this (you will also need to use the execute function):

function! CallPHP()
    execute '!php /home/kbuczynski/diff_re.php fix '.expand('%:p').' flagArg'
endfunction
nnoremap <F2> :call CallPHP()<CR>

Here is some good documentation on dealing with file paths.
