help

If I just run my linter from the command line, I get the following:

    $ ./node_modules/.bin/eslint -f compact src/main.js
    
    /Users/rjayatilleka/Dropbox/code/proton/src/main.js: line 8, col 10, Error - "dummyFunc" is defined but never used (no-unused-vars)
    /Users/rjayatilleka/Dropbox/code/proton/src/main.js: line 10, col 15, Warning - Strings must use singlequote. (quotes)
    
    2 problems

I'm setting makeprg and errorformat as follows (which was just copied from the Syntastic eslint checker):

    set makeprg=./node_modules/.bin/eslint\ -f\ compact\ %
    set errorformat+=%E%f:\ line\ %l\,\ col\ %c\,\ Error\ -\ %m
    set errorformat+=%W%f:\ line\ %l\,\ col\ %c\,\ Warning\ -\ %m

When I run `:make` and `:copen`, I get the following:

    || /Users/rjayatilleka/Dropbox/code/proton/src/main.js: line 8, col 10, Error - "dummyFunc" is defined but never used (no-unused-vars)
    || /Users/rjayatilleka/Dropbox/code/proton/src/main.js: line 10, col 15, Warning - Strings must use singlequote. (quotes)
    || 
    || 2 problems

And the output from `:make` and `:cn` always reference `($ of 4)`. Out of 4, not 2. I just not really sure why my errorformat isn't working. I tried the following errorformats, but they just gave me errors when launching vim.

    set errorformat+=%E\|\| %f:\ line\ %l\,\ col\ %c\,\ Error\ -\ %m
    set errorformat+=%W\|\| %f:\ line\ %l\,\ col\ %c\,\ Warning\ -\ %m
