1. Introduction *ale-introduction*
|
|
|
|
ALE provides the means to run linters asynchronously in Vim in a variety of
|
|
languages and tools. ALE sends the contents of buffers to linter programs
|
|
using the |job-control| features available in Vim 8 and NeoVim. For Vim 8,
|
|
Vim must be compiled with the |job| and |channel| and |timer| features
|
|
as a minimum.
|
|
|
|
ALE supports the following key features:
|
|
|
|
1. Running linters when text is changed.
|
|
2. Running linters when files are opened.
|
|
3. Running linters when files are saved. (When a global flag is set.)
|
|
4. Populating the |loclist| with warning and errors.
|
|
5. Setting |signs| with warnings and errors for error markers.
|
|
6. Using |echo| to show error messages when the cursor moves.
|
|
|
|

3. Global Options *ale-options*
|
|
|
|
g:airline#extensions#ale#enabled *g:airline#extensions#ale#enabled*
|
|
|
|
Type: |Number|
|
|
Default: `1`
|
|
|
|
Enables or disables the |airline|'s native extension for ale, which displays
|
|
warnings and errors in the status line, prefixed by
|
|
|airline#extensions#ale#error_symbol| and
|
|
|airline#extensions#ale#warning_symbol|.
|
|
|
|
|
|
g:ale_echo_cursor *g:ale_echo_cursor*
|
|
|
|
Type: |Number|
|
|
Default: `1`
|
|
|
|
When this option is set to `1`, a truncated message will be echoed when a
|
|
cursor is near a warning or error. ALE will attempt to find the warning or
|
|
error at a column nearest to the cursor when the cursor is resting on a line
|
|
which contains a warning or error. This option can be set to `0` to disable
|
|
this behaviour.
|
|
The format of the message can be customizable in |g:ale_echo_msg_format|.
|
|
|
|
|
|
g:ale_echo_msg_error_str *g:ale_echo_msg_error_str*
|
|
|
|
Type: |String|
|
|
Default: `Error`
|
|
|
|
The string used for error severity in the echoed message.
|
|
Note |`g:ale_echo_cursor`| should be set to 1
|
|
Note |`g:ale_echo_msg_format`| should contain the `%severity%` handler
|
|
|
|
|
|
g:ale_echo_msg_format *g:ale_echo_msg_format*
|
|
|
|
Type: |String|
|
|
Default: `%s`
|
|
|
|
This variable defines the format of the echoed message. The `%s` is the
|
|
error message itself, and it can contain the following handlers:
|
|
- `%linter%` for linter's name
|
|
- `%severity%` for the type of severity
|
|
Note |`g:ale_echo_cursor`| should be setted to 1
|
|
|
|
|
|
g:ale_echo_msg_warning_str *g:ale_echo_msg_warning_str*
|
|
|
|
Type: |String|
|
|
Default: `Warning`
|
|
|
|
The string used for warning severity in the echoed message.
|
|
Note |`g:ale_echo_cursor`| should be set to 1
|
|
Note |`g:ale_echo_msg_format`| should contain the `%severity%` handler
|
|
|
|
|
|
g:ale_keep_list_window_open *g:ale_keep_list_window_open*
|
|
|
|
Type: |Number|
|
|
Default: `0`
|
|
|
|
When set to `1`, this option will keep the loclist or quickfix windows
|
|
event after all warnings/errors have been removed for files. By default
|
|
the loclist or quicfix windows will be closed automatically when there
|
|
are no warnings or errors.
|
|
|
|
See: |g:ale_open_list|
|
|
|
|
|
|
g:ale_lint_delay *g:ale_lint_delay*
|
|
|
|
Type: |Number|
|
|
Default: `200`
|
|
|
|
This variable controls the milliseconds delay after which the linters will
|
|
be run after text is changed. This option is only meaningful with the
|
|
|g:ale_lint_on_text_changed| variable set to `1`.
|
|
|
|
|
|
g:ale_lint_on_enter *g:ale_lint_on_enter*
|
|
|
|
Type: |Number|
|
|
Default: `1`
|
|
|
|
When this option is set to `1`, the |BufEnter| and |BufRead| events will be
|
|
used to apply linters when buffers are first opened. If this is not desired,
|
|
this variable can be set to `0` in your vimrc file to disable this
|
|
behaviour.
|
|
|
|
|
|
g:ale_lint_on_save *g:ale_lint_on_save*
|
|
|
|
Type: |Number|
|
|
Default: `0`
|
|
|
|
This option will make ALE run the linters whenever a file is saved when it
|
|
it set to `1` in your vimrc file. This option can be used in combination
|
|
with the |g:ale_lint_on_enter| and |g:ale_lint_on_text_changed| options to
|
|
make ALE only check files after that have been saved, if that is what is
|
|
desired.
|
|
|
|
|
|
g:ale_lint_on_text_changed *g:ale_lint_on_text_changed*
|
|
|
|
Type: |Number|
|
|
Default: `1`
|
|
|
|
By default, ALE will check files with the various supported programs when
|
|
text is changed by using the |TextChanged| event. If this behaviour is not
|
|
desired, then this option can be disabled by setting it to 0. The
|
|
|g:ale_lint_delay| variable will be used to set a |timer_start()| on a
|
|
delay, and each change to a file will continue to call |timer_stop()| and
|
|
|timer_start()| repeatedly until the timer ticks by, and the linters will be
|
|
run. The checking of files will run in the background, so it should not
|
|
inhibit editing files.
|
|
|
|
|
|
g:ale_linter_aliases *g:ale_linter_aliases*
|
|
|
|
Type: |Dictionary|
|
|
Default: `{}`
|
|
|
|
The |g:ale_linter_aliases| option can be used to set aliases from one
|
|
filetype to another. A given filetype can be mapped to use the linters
|
|
run for another given filetype.
|
|
|
|
This |Dictionary| will be merged with a default dictionary containing the
|
|
following values: >
|
|
|
|
{
|
|
\ 'zsh': 'sh',
|
|
\ 'csh': 'sh',
|
|
\}
|
|
<
|
|
For example, if you wish to map a new filetype `'foobar'` to run the `'php'`
|
|
linters, you could set the following: >
|
|
|
|
let g:ale_linter_aliases = {'foobar': 'php'}
|
|
<
|
|
When combined with the |g:ale_linters| option, the original filetype
|
|
(`'foobar'`) will be used for determining which linters to run,
|
|
not the aliased type (`'php'`). This allows an aliased type to run a
|
|
different set of linters from the type it is being mapped to.
|
|
|
|
|
|
g:ale_linters *g:ale_linters*
|
|
|
|
Type: |Dictionary|
|
|
Default: `{}`
|
|
|
|
The |g:ale_linters| option sets a |Dictionary| mapping a filetype
|
|
to a |List| of linter programs to be run when checking particular filetypes.
|
|
Only the filetypes specified in the dictionary will be limited in terms
|
|
of which linters will be run.
|
|
|
|
This |Dictionary| will be merged with a default dictionary containing the
|
|
following values: >
|
|
|
|
{
|
|
\ 'zsh': ['shell'],
|
|
\ 'csh': ['shell'],
|
|
\}
|
|
<
|
|
This option can be used to enable only a particular set of linters for a
|
|
file. For example, you can enable only 'eslint' for JavaScript files: >
|
|
|
|
let g:ale_linters = {'javascript': ['eslint']}
|
|
<
|
|
If you want to disable all linters for a particular filetype, you can pass
|
|
an empty list of linters as the value: >
|
|
|
|
let g:ale_linters = {'javascript': []}
|
|
<
|
|
All linters available for a given filetype can be enabled by using the
|
|
string `'all'`: >
|
|
|
|
let g:ale_linters = {'c': 'all'}
|
|
<
|
|
|
|
g:ale_open_list *g:ale_open_list*
|
|
|
|
Type: |Number|
|
|
Default: `0`
|
|
|
|
When set to `1`, this will cause ALE to automatically open a window for
|
|
the loclist (|lopen|) or for the quickfix list instead if
|
|
|g:ale_set_quickfix| is `1`. (|copen|)
|
|
|
|
The window will be kept open until all warnings or errors are cleared,
|
|
including those not set by ALE, unless |g:ale_keep_list_window_open| is set
|
|
to `1`, in which case the window will be kept open until closed manually.
|
|
|
|
|
|
g:ale_set_loclist *g:ale_set_loclist*
|
|
|
|
Type: |Number|
|
|
Default: `1`
|
|
|
|
When this option is set to `1`, the |loclist| will be populated with any
|
|
warnings and errors which are found by ALE. This feature can be used to
|
|
implement jumping between errors through typical use of |lnext| and |lprev|.
|
|
|
|
|
|
g:ale_set_quickfix *g:ale_set_quickfix*
|
|
|
|
Type: |Number|
|
|
Default: `0`
|
|
|
|
When this option is set to `1`, the |quickfix| list will be populated with any
|
|
warnings and errors which are found by ALE, instead of the |loclist|. The
|
|
loclist will never be populated when this option is on.
|
|
|
|
|
|
g:ale_set_signs *g:ale_set_signs*
|
|
|
|
Type: |Number|
|
|
Default: `has('signs')`
|
|
|
|
When this option is set to `1`, the |sign| column will be populated with
|
|
signs marking where errors and warnings appear in the file. The
|
|
`ALEErrorSign` and `ALEWarningSign` highlight groups will be used to provide
|
|
highlighting for the signs. The text used for signs can be customised with
|
|
the |g:ale_sign_error| and |g:ale_sign_warning| options.
|
|
|
|
|
|
g:ale_sign_column_always *g:ale_sign_column_always*
|
|
|
|
Type: |Number|
|
|
Default: `0`
|
|
|
|
By default, the sign gutter will disappear when all warnings and errors have
|
|
been fixed for a file. When this option is set to `1`, the sign column will
|
|
remain open. This can be preferable if you don't want the text in your file
|
|
to move around as you edit a file.
|
|
|
|
|
|
g:ale_sign_error *g:ale_sign_error*
|
|
|
|
Type: |String|
|
|
Default: `'>>'`
|
|
|
|
This string can be changed to change the characters used for the sign gutter
|
|
for lines which at least one error on them. Lines with both errors and
|
|
warnings on them will show the error marker, as errors take precedence.
|
|
|
|
|
|
g:ale_sign_offset *g:ale_sign_offset*
|
|
|
|
Type: |Number|
|
|
Default: `1000000`
|
|
|
|
This variable controls offset from which numeric IDs will be generated for
|
|
new signs. Signs cannot share the same ID values, so when two Vim plugins
|
|
set signs at the same time, the IDs have to be configured such that they do
|
|
not conflict with one another. If the IDs used by ALE are found to conflict
|
|
with some other plugin, this offset value can be changed, and hopefully both
|
|
plugins will work together. See |sign-place| for more information on how
|
|
signs are set.
|
|
|
|
|
|
g:ale_sign_warning *g:ale_sign_warning*
|
|
|
|
Type: |String|
|
|
Default: `'--'`
|
|
|
|
This string can be changed to change the characters used for the sign gutter
|
|
for lines which at least one warning on them.
|
|
|
|
|
|
g:ale_statusline_format *g:ale_statusline_format*
|
|
|
|
Type: |List|
|
|
Default: `['%d error(s)', '%d warning(s)', 'OK']`
|
|
|
|
This variable defines the format of |`ale#statusline#status()`| output.
|
|
- The 1st element is for errors
|
|
- The 2nd element is for warnings
|
|
- The 3rd element is for when no errors are detected
|
|
|
|
|
|
g:ale_warn_about_trailing_whitespace *g:ale_warn_about_trailing_whitespace*
|
|
|
|
Type: |Number|
|
|
Default: `1`
|
|
|
|
When this option is set to `1`, warnings relating to trailing whitespace on
|
|
lines will be shown in signs, the loclist, and echo messages, etc. If these
|
|
errors are found to be too irritating while edits are being made, and you
|
|
have configured Vim to automatically remove trailing whitespace, then you
|
|
can disable these warnings for some linters by setting this option to `0`.
|
|
|
|
Not all linters may respect this option. If a linter does not, please file a
|
|
bug report, and it may be possible to add such support.
|
|
|
|
|
|
===============================================================================
|
|
4. Linter Specific Options *ale-linter-options*
|
|
|
|
Some linters have specific options which can be configured for each of them,
|
|
for customising their behaviour.
|
|
|
|
-------------------------------------------------------------------------------
|
|
4.1. eslint *ale-linter-options-eslint*
|
|
|
|
g:ale_javascript_eslint_executable *g:ale_javascript_eslint_executable*
|
|
|
|
Type: |String|
|
|
Default: `'eslint'`
|
|
|
|
ALE will first discover the eslint path in an ancestor node_modules
|
|
directory. If no such path exists, this variable will be used instead.
|
|
|
|
This variable can be set to change the path to eslint. If you have eslint_d
|
|
installed, you can set this option to use eslint_d instead.
|
|
|
|
If you wish to use only a globally installed version of eslint, set
|
|
|g:ale_javascript_eslint_use_global| to `1`.
|
|
|
|
|
|
g:ale_javascript_eslint_options *g:ale_javascript_eslint_options*
|
|
|
|
Type: |String|
|
|
Default: `''`
|
|
|
|
This variable can be set to pass additional options to eslint.
|
|
|
|
|
|
g:ale_javascript_eslint_use_global *g:ale_javascript_eslint_use_global*
|
|
|
|
Type: |String|
|
|
Default: `0`
|
|
|
|
This variable controls whether or not ALE will search for a local path for
|
|
eslint first. If this variable is set to `1`, then ALE will always use the
|
|
global version of eslint, in preference to locally installed versions of
|
|
eslint in node_modules.
|
|
|
|
-------------------------------------------------------------------------------
|
|
4.2. flow *ale-linter-options-flow*
|
|
|
|
g:ale_javascript_flow_executable *g:ale_javascript_flow_executable*
|
|
|
|
Type: |String|
|
|
Default: `'flow'`
|
|
|
|
ALE will first discover the flow path in an ancestor node_modules
|
|
directory. If no such path exists, this variable will be used instead.
|
|
|
|
If you wish to use only a globally installed version of flow, set
|
|
|g:ale_javascript_flow_use_global| to `1`.
|
|
|
|
|
|
g:ale_javascript_flow_use_global *g:ale_javascript_flow_use_global*
|
|
|
|
Type: |String|
|
|
Default: `0`
|
|
|
|
This variable controls whether or not ALE will search for a local path for
|
|
flow first. If this variable is set to `1`, then ALE will always use the
|
|
global version of flow, in preference to locally installed versions of
|
|
flow in node_modules.
|
|
|
|
-------------------------------------------------------------------------------
|
|
4.3. jshint *ale-linter-options-jshint*
|
|
|
|
g:ale_javascript_jshint_executable *g:ale_javascript_jshint_executable*
|
|
|
|
Type: |String|
|
|
Default: `'jshint'`
|
|
|
|
ALE will first discover the jshint path in an ancestor node_modules
|
|
directory. If no such path exists, this variable will be used instead.
|
|
|
|
This variable can be changed to change the path to jshint.
|
|
|
|
If you wish to use only a globally installed version of jshint, set

5. Linter Integration Notes *ale-linter-integration*
|
|
|
|
Some linters may have requirements for some other plugins being installed.
|
|
|
|
-------------------------------------------------------------------------------
|
|
5.1. ocaml-merlin *ale-integration-ocaml-merlin*
|
|
|
|
To use merlin linter for OCaml source code you need to make sure Merlin for
|
|
Vim is correctly configured. See the corresponding Merlin wiki page for
|
|
detailed instructions
|
|
(https://github.com/the-lambda-church/merlin/wiki/vim-from-scratch).
|
|
|
|
-------------------------------------------------------------------------------
|
|
5.2. rust *ale-integration-rust*
|
|
|
|
Since Vim does not detect the rust file type out-of-the-box, you need the
|
|
runtime files for rust from here: https://github.com/rust-lang/rust.vim
|
|
|
|
Note that there are two possible linters for rust files:
|
|
|
|
1. rustc -- The Rust compiler is used to check the currently edited file.
|
|
So, if your project consists of multiple files, you will get some errors
|
|
when you use e.g. a struct which is defined in another file. You can use
|
|
|g:ale_rust_ignore_error_codes| to ignore some of these errors.
|
|
2. cargo -- If your project is managed by Cargo, the whole project is
|
|
checked. That means that all errors are properly shown, but cargo can
|
|
only operate on the files written on disk. That means it is highly
|
|
recommended to turn off |g:ale_lint_on_text_changed| and to turn on
|
|
|g:ale_lint_on_save|.
|
|
|
|
Also note that rustc 1.12. or later is needed.
|
|
|
|

6. Commands/Keybinds *ale-commands*
|
|
|
|
ALEPrevious *ALEPrevious*
|
|
ALEPreviousWrap *ALEPreviousWrap*
|
|
ALENext *ALENext*
|
|
ALENextWrap *ALENextWrap*
|
|
*ale-navigation-commands*
|
|
|
|
Move between warnings or errors in a buffer.
|
|
|
|
`ALEPrevious` and `ALENext` will stop at the top and bottom of a file, while
|
|
`ALEPreviousWrap` and `ALENextWrap` will wrap around the file to find
|
|
the last or first warning or error in the file, respectively.
|
|
|
|
The following |<Plug>| mappings are defined for the commands: >
|
|
<Plug>(ale_previous) - ALEPrevious
|
|
<Plug>(ale_previous_wrap) - ALEPreviousWrap
|
|
<Plug>(ale_next) - ALENext
|
|
<Plug>(ale_next_wrap) - ALENextWrap
|
|
<
|
|
For example, these commands could be bound to the keys Ctrl + j
|
|
and Ctrl + k: >
|
|
|
|
" Map movement through errors without wrapping.
|
|
nmap <silent> <C-k> <Plug>(ale_previous)
|
|
nmap <silent> <C-j> <Plug>(ale_next)
|
|
" OR map keys to use wrapping.
|
|
nmap <silent> <C-k> <Plug>(ale_previous_wrap)
|
|
nmap <silent> <C-j> <Plug>(ale_next_wrap)
|

7. API *ale-api*
|
|
|
|
ale#Queue(delay) *ale#Queue()*
|
|
Run linters for the current buffer, based on the filetype of the buffer,
|
|
with a given `delay`. A `delay` of `0` will run the linters immediately.
|
|
The linters will always be run in the background. Calling this function
|
|
again from the same buffer
|
|
|
|
|
|
ale#engine#GetLoclist(buffer) *ale#engine#GetLoclist()*
|
|
|
|
Given a buffer number, this function will rerurn the list of warnings and
|
|
errors reported by ALE for a given buffer in the format accepted by
|
|
|setqflist()|.
|
|
|
|
|
|
ale#linter#Define(filetype, linter) *ale#linter#Define()*
|
|
Given a |String| for a filetype and a |Dictionary| Describing a linter
|
|
configuration, add a linter for the given filetype. The dictionaries each
|
|
offer the following options:
|
|
|
|
`name` The name of the linter. These names will be used by
|
|
|g:ale_linters| option for enabling/disabling
|
|
particular linters.
|
|
|
|
This argument is required.
|
|
|
|
`callback` A |String| or |Funcref| for a callback function
|
|
accepting two arguments (buffer, lines), for a
|
|
buffer number the output is for, and the lines of
|
|
output from a linter.
|
|
|
|
This callback function should return a |List| of
|
|
|Dictionary| objects in the format accepted by
|
|
|setqflist()|. The |List| will be sorted by line and
|
|
then column order so it can be searched with a binary
|
|
search by in future before being passed on to the
|
|
|loclist|, etc.
|
|
|
|
This argument is required.
|
|
|
|
`executable` A |String| naming the executable itself which
|
|
will be run. This value will be used to check if the
|
|
program requested is installed or not.
|
|
|
|
Either this or the `executable_callback` argument
|
|
must be provided.
|
|
|
|
`executable_callback ` A |String| or |Funcref| for a callback function
|
|
accepting a buffer number. A |String| should be
|
|
returned for the executable to check. This can be
|
|
used in place of `executable` when more complicated
|
|
processing is needed.
|
|
|
|
`command` A |String| for an executable to run asynchronously.
|
|
This command will be fed the lines from the buffer to
|
|
check, and will produce the lines of output given to
|
|
the `callback`.
|
|
|
|
`command_callback` A |String| or |Funcref| for a callback function
|
|
accepting a buffer number. A |String| should be
|
|
returned for a command to run. This can be used in
|
|
place of `command` when more complicated processing
|
|
is needed.
|
|
|
|
`command_chain` A |List| of |Dictionary| items defining a series
|
|
of commands to be run. At least one |Dictionary|
|
|
should be provided. Each Dictionary must contain the

|
key `callback`, defining a |String| or |Funcref| for
|
|
a function returning a |String| for a command to run.
|
|
|
|
The callback functions for each command after the
|
|
first command in in the chain should accept two
|
|
arguments `(buffer, output)`, a buffer number and a
|
|
|List| of lines of output from the previous command
|
|
in the chain.
|
|
|
|
The first callback function in a chain accepts only
|
|
a `(buffer)` argument, as there are no previous
|
|
commands to run which return `output`.
|
|
|
|
Commands in the chain will all use the
|
|
`output_stream` value provided in the root
|
|
|Dictionary|. Each command in the chain can also
|
|
provide an `output_stream` key to override this value.
|
|
See the `output_stream` description for more
|
|
information.
|
|
|
|
The Vim buffer being checked for linter will only
|
|
be sent to the final command in the chain. Previous
|
|
commands in the chain will receive no input from
|
|
stdin.
|
|
|
|
`output_stream` A |String| for the output stream the lines of output
|
|
should be read from for the command which is run. The
|
|
accepted values are `'stdout'`, `'stderr'`, and
|
|
`'both'`. This argument defaults to `'stdout'`. This
|
|
argument can be set for linter programs which output
|
|
their errors and warnings to the stderr stream
|
|
instead of stdout. The option `'both'` will read
|
|
from both stder and stdout at the same time.
|
|
|
|
Only one of `command`, `command_callback`, or `command_chain` should be
|
|
specified. `command_callback` is generally recommended when a command string
|
|
needs to be generated dynamically, or any global options are used.
|
|
`command_chain` is recommended where any system calls need to be made to
|
|
retrieve some kind of information before running the final command.
|
|
|
|
Some programs for checking for errors are not capable of receiving input
|
|
from stdin, as is required by ALE. To remedy this, a wrapper script is
|
|
provided named in the variable |g:ale#util#stdin_wrapper|. This variable
|
|
can be called with the regular arguments for any command to forward data
|
|
from stdin to the program, by way of creating a temporary file. The first
|
|
argument to the stdin wrapper must be a file extension to save the temporary
|
|
file with, and the following arguments are the command as normal.
|
|
For example: >
|
|
'command': g:ale#util#stdin_wrapper . ' .hs ghc -fno-code -v0',
|
|
<
|
|
|
|
ale#linter#Get(filetype) *ale#linter#Get()*
|
|
Return all of linters configured for a given filetype as a |List| of
|
|
|Dictionary| values in the format specified by |ale#linter#Define()|.
|
|
|
|
Filetypes may be dot-seperated to invoke linters for multiple filetypes:
|
|
for instance, the filetype `javascript.jsx` will return linters for both the
|
|
`javascript` and `jsx` filetype.
|
|
|
|
Aliases may be defined in as described in |g:ale_linter_aliases|. Aliases
|
|
are applied after dot-seperated filetypes are broken up into their
|
|
components.
|
|
|
|
|
|
ale#statusline#Status() *ale#statusline#Status()*
|
|
Return a formatted string that can be added to the statusline.
|
|
The output's format is defined in |`g:ale_statusline_format`|.
|
|
To enable it, the following should be present in your |statusline| settings: >
|
|
%{ale#statusline#Status()}
|
|
|
|
|
|
g:ale#util#stdin_wrapper *g:ale#util#stdin_wrapper*
|
|
This variable names a wrapper script for sending stdin input to programs
|
|
which cannot accept input via stdin. See |ale#linter#Define()| for more.
|
|
|
|
|
|
ALELint *ALELint*
|
|
This |User| autocommand is triggered by ALE every time it completes a lint
|
|
operation. It can be used to update statuslines, send notifications, or
|
|
complete any other operation that needs to be done after a lint run.
|
|
It can be used simply:
|
|
autocmd User ALELint echom "ALE run!"
