Autocompile in Vim

[Anton Curl]

Hi everyone!

I share the solution I've found to automatically compile a Lilypond file in Vim.
The compilation runs in background after saving the buffer, and errors are added to the quickfix list.
I inspired myself from this script: https://github.com/vim-scripts/makebg

First you must run Vim in server mode.
For this I use an alias in my .bashrc:

vim_server () {
    vim --servername "$(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 32 | head -n 1)" "$@"
}
alias vim='vim_server'

Then you have to put this in your .vimrc:

function Makebg(make_cmd, make_target, make_filter)
    execute "silent !makebg" v:servername
                \ shellescape(a:make_cmd, 1)    . " " .
                \ shellescape(a:make_target, 1) . " " .
                \ shellescape(a:make_filter, 1)
    redraw!
endfunction
command -nargs=0 Makebg call Makebg(b:make_cmd, b:make_target, b:make_filter)
let b:make_cmd = "make"
let b:make_target = ""
let b:make_filter = "cat"

autocmd Filetype lilypond call SetLilypondOptions()
function SetLilypondOptions()
    if filereadable("Makefile")
        let b:make_cmd = "make"
        let b:make_target = ""
    else
        let b:make_cmd = "lilypond"
        let b:make_target = expand("%")
    endif
    let b:make_filter = "lilypond_error_filter"
    setlocal efm=%f:%l:%c:%m
    autocmd BufWritePost <buffer> Makebg
endfunction

Finally you must have the two enclosed scripts in your $PATH.

That's all!
Note that you can use the Makebg function for other types of files.
