|
Neomake is a plugin for [Vim]/[Neovim] to asynchronously run programs.
|
|
|
|
You can use it instead of the built-in `:make` command (since it can pick
|
|
up your `'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.
|
|
|
|
## Requirements
|
|
|
|
### Neovim
|
|
|
|
With Neovim any release will do (after 0.0.0-alpha+201503292107).
|
|
|
|
### Vim
|
|
|
|
The minimal Vim version supported by Neomake is 7.4.503 (although if you don't
|
|
use `g:neomake_logfile` older versions will probably work fine as well).
|
|
|
|
You need Vim 8.0.0027 or later for asynchronous features.
|
|
|
|
## Installation
|
|
|
|
Use your preferred installation method for Vim plugins.
|
|
|
|
With [vim-plug](https://github.com/junegunn/vim-plug) that would mean to add
|
|
the following to your vimrc:
|
|
|
|
```vim
|
|
Plug 'neomake/neomake'
|
|
```
|
|
|
|
## Setup
|
|
|
|
If you want to run Neomake automatically (in file mode), you can configure it
|
|
in your `vimrc` by using `neomake#configure#automake`, e.g. by picking one of:
|
|
|
|
```vim
|
|
" 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 500ms; 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.)
|
|
|
|
### Advanced setup
|
|
|
|
The author liked to use the following, which uses different modes based on if
|
|
your laptop runs on battery (for MacOS or Linux):
|
|
|
|
```vim
|
|
function! MyOnBattery()
|
|
if has('macunix')
|
|
return match(system('pmset -g batt'), "Now drawing from 'Battery Power'") != -1
|
|
elseif has('unix')
|
|
return readfile('/sys/class/power_supply/AC/online') == ['0']
|
|
endif
|
|
return 0
|
|
endfunction
|
|
|
|
if MyOnBattery()
|
|
call neomake#configure#automake('w')
|
|
else
|
|
call neomake#configure#automake('nw', 1000)
|
|
endif
|
|
```
|
|
|
|
See `:help neomake-automake` (in [doc/neomake.txt](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
|
|
modes.
|
|
|
|
## Usage
|
|
|
|
When calling `: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 `:lwindow` /
|
|
`:lopen` (to view the list) and `:lprev` / `:lnext` to go back and forth.
|
|
|
|
You can configure Neomake to open the list automatically:
|
|
|
|
```vim
|
|
let g:neomake_open_list = 2
|
|
```
|
|
|
|
Please refer to [`:help neomake.txt`] for more details on configuration.
|
|
|
|
### Maker types
|
|
|
|
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 `:Neomake!`.
|
|
|
|
See [`: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
|
|
name, e.g. `:Neomake jshint` (you can use Vim's completion here to complete
|
|
maker names).
|
|
|
|
## Default makers

|
|
repository! Check out `autoload/neomake/makers/**/*.vim` for existing makers.
|
|
|
|
This is a community driven project, and maintainers are wanted.

|
You should have a good profile of issue triaging and PRs on this repo already.

|
## Hacking / Testing
|
|
|
|
We are using [Vader](https://github.com/junegunn/vader.vim) for our tests.
|
|
|
|
### Logging
|
|
|
|
Set `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 `tail -f`).
|
|
You can use Ctrl-C to interrupt for scrolling etc, and then F to follow again.
|
|
|
|
### Running tests
|
|
|
|
#### Run all tests against your local Neovim and Vim
|
|
|
|
make test
|
|
|
|
#### Run a specific test file
|
|
|
|
make tests/integration.vader
|
|
|
|
#### Run some specific tests for Vim
|
|
|
|
make testvim VADER_ARGS=tests/integration.vader
|
|
|
|
### Dockerized tests
|
|
|
|
The `docker_test` target runs tests for a specific Vim version.
|
|
See `Dockerfile.tests` for the Vim versions provided in the Docker image.
|
|
|
|
The image for this gets pulled from Docker Hub via
|
|
[neomake/vims-for-tests](https://hub.docker.com/r/neomake/vims-for-tests/).
|
|
|
|
NOTE: the Docker image used for tests does not include (different versions)
|
|
of Neovim at the moment.
|
|
|
|
#### Run all tests for Vim 8.0.586
|
|
|
|
make docker_test DOCKER_VIM=vim-8.0.586
|
|
|
|
#### Run all tests against all Vims in the Docker image
|
|
|
|
make docker_test_all
