You can use it instead of the built-in
:make command (since it can pick
'makeprg' setting), but its focus is on providing an extra layer
of makers based on the current file (type) or project.
Its origin is a proof-of-concept for Syntastic to be asynchronous.
With Neovim any release will do (after 0.0.0-alpha+201503292107).
The minimal Vim version supported by Neomake is 7.4.503 (although if you don't
g:neomake_logfile older versions will probably work fine as well).
You need Vim 8.0.0027 or later for asynchronous features.
Use your preferred installation method for Vim plugins.
With vim-plug that would mean to add the following to your vimrc:
If you want to run Neomake automatically (in file mode), you can configure it
vimrc by using
neomake#configure#automake, e.g. by picking one of:
" When writing a buffer (no delay). call neomake#configure#automake('w') " When writing a buffer (no delay), and on normal mode changes (after 750ms). call neomake#configure#automake('nw', 750) " When reading a buffer (after 1s), and when writing (no delay). call neomake#configure#automake('rw', 1000) " Full config: when writing or reading a buffer, and on changes in insert and " normal mode (after 1s; no delay when writing). call neomake#configure#automake('nrwi', 500)
(Any function calls like these need to come after indicating the end of plugins
to your plugin manager, e.g. after
call plug#end() with vim-plug.)
The author likes the following, which uses different modes based on if your laptop runs on battery (for Linux):
function! MyOnBattery() return readfile('/sys/class/power_supply/AC/online') == ['0'] endfunction if MyOnBattery() call neomake#configure#automake('w') else call neomake#configure#automake('nw', 1000) endif
:help neomake-automake (in doc/neomake.txt) for more
information, e.g. how to configure it based on certain autocommands explicitly,
and for details about which events get used for the different string-based
:Neomake manually (or automatically through
neomake#configure#automake (see above)) it will populate the window's
location list with any issues that get reported by the maker(s).
You can then navigate them using the built-in methods like
:lopen (to view the list) and
:lnext to go back and forth.
You can configure Neomake to open the list automatically:
let g:neomake_open_list = 2
Please refer to
:help neomake.txt for more details on configuration.
There are two types of makers: file makers (acting on the current buffer) and project makers (acting globally).
You invoke file makers using
:Neomake, and project makers using
:help neomake.txt for more details.
Manually run a maker
You can run a specific maker on the current file by specifying the maker's
:Neomake jshint (you can use Vim's completion here to complete
For a list of default makers please see the Makers page in the wiki.
If you find this plugin useful, please contribute your maker recipes to the
repository! Check out
autoload/neomake/makers/**/*.vim for existing makers.
This is a community driven project, and maintainers are wanted. Please contact @blueyed if you are interested. You should have a good profile of issue triaging and PRs on this repo already.
Hacking / Testing
We are using Vader for our tests.
let g:neomake_logfile = '/tmp/neomake.log' (dynamically or in your vimrc)
to enable debug logging to the given file.
From Neomake's source tree you can then run
make tail_log, which will color
the output and pipe it into
less, which folds long lines by default and will
follow the output (like
You can use Ctrl-C to interrupt for scrolling etc, and then F to follow again.
