Test multiline error messages

[benekastah]

I suspect that multiline error messages will not work currently. We may need to join all lines back into a string with newlines before we feed it to the location/quickfix list. We may also need to gather all errors until the job completes before we populate the list for some checkers.

I currently have this problem with the Kibit Clojure code analyzer. I'm using these settings to parse multiline messages:

setlocal makeprg=lein\ kibit\ %
setlocal errorformat=%IAt\ %f:%l:,%C%m,%Z,%-G%.%#
let g:neomake_clojure_kibit_maker = {
    \ 'exe': 'lein',
    \ 'args': ['kibit'],
    \ 'errorformat': '%IAt\ %f:%l:,%C%m,%Z,%-G%.%#',
    \ }
let g:neomake_clojure_enabled_makers = ['kibit']

Kibits output:

At test.clj:1:
Consider using:
  (when true 42)
instead of:
  (if true 42 nil)

:makes output:

test.clj|1 info|  Consider using: (when true 42) instead of: (if true 42 nil)

:Neomakes output:

test.clj|1 info|  Consider using: (when true 42) instead of:

As you can see, the last line gets lost.

Yup. I did some investigation, and it looks like multiline messages will work fine, as long as the whole message comes through in the same stdout/stderr event. If it gets split across events, it will mess up the parsing of the message. The best solution I can think of is to make a setting to gather all the maker output before trying to put it in the loclist or quickfix list.

This feature should be added in e1bce3d. Try adding 'buffer_output': 1 to your kibit maker. It should take care of it for you. Let me know if this resolves it.

Works now as expected. Thanks!
