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 |timers| features
|
|
|
|
|
as a minimum.
|
|
|
|
|
|
|
|
|
|
ALE supports the following key features for linting:
|
|
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
7. Setting syntax highlights for errors.
|
|
|
|
|
|
|
|
|
|
ALE can fix problems with files with the |ALEFix| command, using the same job
|
|
|
|
|
control functionality used for checking for problems. Try using the
|
|
|
|
|
|ALEFixSuggest| command for browsing tools that can be used to fix problems
|
|
|
|
|
for the current buffer.

3. Linting *ale-lint*
|
|
|
|
|
|
|
|
|
|
ALE's primary focus is on checking for problems with your code with various
|
|
|
|
|
programs via some Vim code for integrating with those programs, referred to
|
|
|
|
|
as 'linters.' ALE supports a wide array of programs for linting by default,
|
|
|
|
|
but additional programs can be added easily by defining files in |runtimepath|
|
|
|
|
|
with the filename pattern `ale_linters/<filetype>/<filename>.vim`. For more
|
|
|
|
|
information on defining new linters, see the extensive documentation
|
|
|
|
|
for |ale#linter#Define()|.
|
|
|
|
|
|
|
|
|
|
Without any configuration, ALE will attempt to check all of the code for every
|
|
|
|
|
file you open in Vim with all available tools by default. To see what ALE
|
|
|
|
|
is doing, and what options have been set, try using the |:ALEInfo| command.
|
|
|
|
|
|
|
|
|
|
Most of the linters ALE runs will check the Vim buffer you are editing instead
|
|
|
|
|
of the file on disk. This allows you to check your code for errors before you
|
|
|
|
|
have even saved your changes. ALE will check your code in the following
|
|
|
|
|
circumstances, which can be configured with the associated options.
|
|
|
|
|
|
|
|
|
|
* When you modify a buffer. - |g:ale_lint_on_text_changed|
|
|
|
|
|
* When you open a new or modified buffer. - |g:ale_lint_on_enter|
|
|
|
|
|
* When you save a buffer. - |g:ale_lint_on_save|
|
|
|
|
|
* When the filetype changes for a buffer. - |g:ale_lint_on_filetype_changed|
|
|
|
|
|
* If ALE is used to check code manually. - |:ALELint|
|
|
|
|
|
|
|
|
|
|
In addition to the above options, ALE can also check buffers for errors when
|
|
|
|
|
you leave insert mode with |g:ale_lint_on_insert_leave|, which is off by
|
|
|
|
|
default. It is worth reading the documentation for every option.
|
|
|
|
|
|
|
|
|
|
*ale-lint-file-linters*
|
|
|
|
|
|
|
|
|
|
Some programs must be run against files which have been saved to disk, and
|
|
|
|
|
simply do not support reading temporary files or stdin, either of which are
|
|
|
|
|
required for ALE to be able to check for errors as you type. The programs
|
|
|
|
|
which behave this way are documented in the lists and tables of supported
|
|
|
|
|
programs. ALE will only lint files with these programs in the following
|
|
|
|
|
circumstances.
|
|
|
|
|
|
|
|
|
|
* When you open a new or modified buffer. - |g:ale_lint_on_enter|
|
|
|
|
|
* When you save a buffer. - |g:ale_lint_on_save|
|
|
|
|
|
* When the filetype changes for a buffer. - |g:ale_lint_on_filetype_changed|
|
|
|
|
|
* If ALE is used to check code manually. - |:ALELint|
|
|
|
|
|
|
|
|
|
|
ALE will report problems with your code in the following ways, listed with
|
|
|
|
|
their relevant options.
|
|
|
|
|
|
|
|
|
|
* By updating loclist. (On by default) - |g:ale_set_loclist|
|
|
|
|
|
* By updating quickfix. (Off by default) - |g:ale_set_quickfix|
|
|
|
|
|
* By setting error highlights. - |g:ale_set_highlights|
|
|
|
|
|
* By creating signs in the sign column. - |g:ale_set_signs|
|
|
|
|
|
* By echoing messages based on your cursor. - |g:ale_echo_cursor|
|
|
|
|
|
* By showing balloons for your mouse cursor - |g:ale_set_balloons|
|
|
|
|
|
|
|
|
|
|
Please consult the documentation for each option, which can reveal some other
|
|
|
|
|
ways of tweaking the behaviour of each way of displaying problems. You can
|
|
|
|
|
disable or enable whichever options you prefer.
|
|
|
|
|
|
|
|
|
|
Most settings can be configured for each buffer. (|b:| instead of |g:|),
|
|
|
|
|
including disabling ALE for certain buffers with |b:ale_enabled|. The
|
|
|
|
|
|g:ale_pattern_options| setting can be used to configure files differently
|
|
|
|
|
based on regular expressions for filenames. For configuring entire projects,
|
|
|
|
|
the buffer-local options can be used with external plugins for reading Vim
|
|
|
|
|
project configuration files. Buffer-local settings can also be used in
|
|
|
|
|
ftplugin files for different filetypes.
|
|
|
|
|
|
2018-06-14 06:31:12 -04:00
|
|
|
ALE offers several options for controlling which linters are run.
|
|
|
|
|
|
|
|
|
|
* Selecting linters to run. - |g:ale_linters|
|
|
|
|
|
* Aliasing filetypes for linters - |g:ale_linter_aliases|
|
|
|
|
|
* Only running linters you asked for. - |g:ale_linters_explicit|

4. Fixing Problems *ale-fix*
|
|
|
|
|
|
2018-06-14 06:31:12 -04:00
|
|
|
ALE can fix problems with files with the |ALEFix| command. |ALEFix|
|
|
|
|
|
accepts names of fixers to be applied as arguments. Alternatively,
|
|
|
|
|
when no arguments are provided, the variable |g:ale_fixers| will be
|
|
|
|
|
read for getting a |List| of commands for filetypes, split on `.`, and
|
|
|
|
|
the functions named in |g:ale_fixers| will be executed for fixing the
|
|
|
|
|
errors.
|
2018-03-31 10:55:20 -04:00
|
|
|
|
|
|
|
|
The |ALEFixSuggest| command can be used to suggest tools that be used to
|
|
|
|
|
fix problems for the current buffer.
|
|
|
|
|
|
|
|
|
|
The values for `g:ale_fixers` can be a list of |String|, |Funcref|, or
|
|
|
|
|
|lambda| values. String values must either name a function, or a short name
|
|
|
|
|
for a function set in the ALE fixer registry.
|
|
|
|
|
|
|
|
|
|
Each function for fixing errors must accept either one argument `(buffer)` or
|
|
|
|
|
two arguments `(buffer, lines)`, representing the buffer being fixed and the
|
|
|
|
|
lines to fix. The functions must return either `0`, for changing nothing, a
|
|
|
|
|
|List| for new lines to set, or a |Dictionary| for describing a command to be
|
|
|
|
|
run in the background.
|
|
|
|
|
|
|
|
|
|
Functions receiving a variable number of arguments will not receive the second
|
|
|
|
|
argument `lines`. Functions should name two arguments if the `lines` argument
|
|
|
|
|
is desired. This is required to avoid unnecessary copying of the lines of
|
|
|
|
|
the buffers being checked.
|
|
|
|
|
|
|
|
|
|
When a |Dictionary| is returned for an |ALEFix| callback, the following keys
|
|
|
|
|
are supported for running the commands.
|
|
|
|
|
|
|
|
|
|
`command` A |String| for the command to run. This key is required.
|
|
|
|
|
|
|
|
|
|
When `%t` is included in a command string, a temporary
|
|
|
|
|
file will be created, containing the lines from the file
|
|
|
|
|
after previous adjustment have been done.
|
|
|
|
|
|
|
|
|
|
`read_temporary_file` When set to `1`, ALE will read the contents of the
|
|
|
|
|
temporary file created for `%t`. This option can be used
|
|
|
|
|
for commands which need to modify some file on disk in
|
|
|
|
|
order to fix files.
|
|
|
|
|
|
|
|
|
|
`process_with` An optional callback for post-processing.
|
|
|
|
|
|
|
|
|
|
The callback must accept two arguments,
|
|
|
|
|
`(buffer, output)`, which can be used for converting
|
|
|
|
|
the output from a command into lines to replace the
|
|
|
|
|
buffer's contents with.
|
|
|
|
|
|
|
|
|
|
A |List| of |String|s must be returned.
|
|
|
|
|
|
|
|
|
|
`chain_with` An optional key for defining a callback to call next.
|
|
|
|
|
|
|
|
|
|
The callback must accept two or three arguments,
|
|
|
|
|
`(buffer, output)` or `(buffer, output, input)` .
|
|
|
|
|
Functions receiving a variable number of arguments will
|
|
|
|
|
only receive the first two values. The `output` argument
|
|
|
|
|
will contain the lines of output from the command run.
|
|
|
|
|
The `input` argument is the List of lines for the
|
|
|
|
|
buffer, after applying any previous fixers.
|
|
|
|
|
|
|
|
|
|
The callback must return the same values returned for
|
|
|
|
|
any fixer function. This allows fixer functions to be
|
|
|
|
|
chained recursively.
|
|
|
|
|
|
|
|
|
|
When the command string returned for a fixer is an empty
|
|
|
|
|
string, the next command in the chain will still be run.
|
|
|
|
|
This allows commands to be skipped, like version checks
|
|
|
|
|
that are cached. An empty List will be passed to the
|
|
|
|
|
next callback in the chain for the `output`.
|
|
|
|
|
|
|
|
|
|
`read_buffer` An optional key for disabling reading the buffer.
|
|
|
|
|
|
|
|
|
|
When set to `0`, ALE will not pipe the buffer's data
|
|
|
|
|
into the command via stdin. This option is ignored and
|
|
|
|
|
the buffer is not read when `read_temporary_file` is
|
|
|
|
|
`1`.
|
|
|
|
|
|
|
|
|
|
This option defaults to `0` when `chain_with` is defined
|
|
|
|
|
as anything other than `v:null`, and defaults to `1`
|
|
|
|
|
otherwise. This is so earlier commands in a chain
|
|
|
|
|
do not receive the buffer's data by default.
|
|
|
|
|
|
|
|
|
|
*ale-fix-configuration*
|
|
|
|
|
|
|
|
|
|
Synchronous functions and asynchronous jobs will be run in a sequence for
|
|
|
|
|
fixing files, and can be combined. For example:
|
|
|
|
|
>
|
|
|
|
|
let g:ale_fixers = {
|
|
|
|
|
\ 'javascript': [
|
|
|
|
|
\ 'DoSomething',
|
|
|
|
|
\ 'eslint',
|
|
|
|
|
\ {buffer, lines -> filter(lines, 'v:val !=~ ''^\s*//''')},
|
|
|
|
|
\ ],
|
|
|
|
|
\}
|
|
|
|
|
|
|
|
|
|
ALEFix
|
|
|
|
|
<
|
|
|
|
|
The above example will call a function called `DoSomething` which could act
|
|
|
|
|
upon some lines immediately, then run `eslint` from the ALE registry, and
|
|
|
|
|
then call a lambda function which will remove every single line comment
|
|
|
|
|
from the file.
|
|
|
|
|
|
|
|
|
|
For buffer-local settings, such as in |g:ale_pattern_options| or in ftplugin
|
|
|
|
|
files, a |List| may be used for configuring the fixers instead.
|
|
|
|
|
>
|
|
|
|
|
" Same as the above, only a List can be used instead of a Dictionary.
|
|
|
|
|
let b:ale_fixers = [
|
|
|
|
|
\ 'DoSomething',
|
|
|
|
|
\ 'eslint',
|
|
|
|
|
\ {buffer, lines -> filter(lines, 'v:val !=~ ''^\s*//''')},
|
|
|
|
|
\]
|
|
|
|
|
|
|
|
|
|
ALEFix
|
|
|
|
|
<
|
|
|
|
|
For convenience, a plug mapping is defined for |ALEFix|, so you can set up a
|
|
|
|
|
keybind easily for fixing files. >
|
|
|
|
|
|
|
|
|
|
" Bind F8 to fixing problems with ALE
|
|
|
|
|
nmap <F8> <Plug>(ale_fix)
|
|
|
|
|
<
|
|
|
|
|
Files can be fixed automatically with the following options, which are all off
|
|
|
|
|
by default.
|
|
|
|
|
|
|
|
|
|
|g:ale_fix_on_save| - Fix files when they are saved.

5. Language Server Protocol Support *ale-lsp*
|
|
|
|
|
|
|
|
|
|
ALE offers some support for integrating with Language Server Protocol (LSP)
|
|
|
|
|
servers. LSP linters can be used in combination with any other linter, and
|
|
|
|
|
will automatically connect to LSP servers when needed. ALE also supports
|
|
|
|
|
`tsserver` for TypeScript, which uses a different but very similar protocol.
|
|
|
|
|
|
|
|
|
|
ALE supports the following LSP/tsserver features.
|
|
|
|
|
|
|
|
|
|
1. Diagnostics/linting - Enabled via selecting linters as usual.
|
|
|
|
|
2. Completion (Only for tsserver)
|
|
|
|
|
3. Go to definition
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
-------------------------------------------------------------------------------
|
|
|
|
|
5.1 Completion *ale-completion*
|
|
|
|
|
|
|
|
|
|
NOTE: At the moment, only `tsserver` for TypeScript code is supported for
|
|
|
|
|
completion.
|
|
|
|
|
|
|
|
|
|
ALE offers limited support for automatic completion of code while you type.
|
|
|
|
|
Completion is only supported while a least one LSP linter is enabled. ALE
|
|
|
|
|
will only suggest symbols provided by the LSP servers.
|
|
|
|
|
|
|
|
|
|
Suggestions will be made while you type after completion is enabled.
|
|
|
|
|
Completion can be enabled by setting |g:ale_completion_enabled| to `1`. The
|
|
|
|
|
delay for completion can be configured with |g:ale_completion_delay|. ALE will
|
|
|
|
|
only suggest so many possible matches for completion. The maximum number of
|
|
|
|
|
items can be controlled with |g:ale_completion_max_suggestions|.
|
|
|
|
|
|
2018-06-14 06:31:12 -04:00
|
|
|
If you don't like some of the suggestions you see, you can filter them out
|
|
|
|
|
with |g:ale_completion_excluded_words| or |b:ale_completion_excluded_words|.
|
|
|
|
|
|

|
|
|
|
|
|
|
|
-------------------------------------------------------------------------------
|
|
|
|
|
5.2 Go To Definition *ale-go-to-definition*
|
|
|
|
|
|
|
|
|
|
ALE supports jumping to the files and locations where symbols are defined
|
|
|
|
|
through any enabled LSP linters. The locations ALE will jump to depend on the
|
|
|
|
|
information returned by LSP servers. The following commands are supported:
|
|
|
|
|
|
|
|
|
|
|ALEGoToDefinition| - Open the definition of the symbol under the cursor.
|
|
|
|
|
|ALEGoToDefinitionInTab| - The same, but for opening the file in a new tab.
|
|
|
|
|
|
|
|
|
|
|
2018-06-14 06:31:12 -04:00
|
|
|
-------------------------------------------------------------------------------
|
|
|
|
|
5.3 Find References *ale-find-references*
|
|
|
|
|
|
|
|
|
|
ALE supports finding references for symbols though any enabled LSP linters.
|
|
|
|
|
ALE will display a preview window showing the places where a symbol is
|
|
|
|
|
referenced in a codebase when a command is run. The following commands are
|
|
|
|
|
supported:
|
|
|
|
|
|
|
|
|
|
|ALEFindReferences| - Find references for the word under the cursor.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
-------------------------------------------------------------------------------
|
|
|
|
|
5.4 Hovering *ale-hover*
|
|
|
|
|
|
|
|
|
|
ALE supports "hover" information for printing brief information about symbols
|
|
|
|
|
at the cursor taken from LSP linters. The following commands are supported:
|
|
|
|
|
|
|
|
|
|
|ALEHover| - Print information about the symbol at the cursor.
|
|
|
|
|
|
|
|
|
|
If |b:ale_set_balloons| is set to `1` and your version of Vim supports the
|
|
|
|
|
|balloon_show()| function, then "hover" information also show up when you move
|
|
|
|
|
the mouse over a symbol in a buffer. Diagnostic information will take priority
|
|
|
|
|
over hover information for balloons. If a line contains a problem, that
|
|
|
|
|
problem will be displayed in a balloon instead of hover information.
|
|
|
|

|
|
|
|
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|.
|
|

|
Default: undefined
|
2018-03-31 10:55:20 -04:00
|
|
|
|
|
|
|
|
When set to `1`, ALE will cache failing executable checks for linters. By
|
|
|
|
|
default, only executable checks which succeed will be cached.
|
|
|
|
|
|
|
|
|
|
When this option is set to `1`, Vim will have to be restarted after new
|
|
|
|
|
executables are installed for ALE to be able to run linters for those
|
|
|
|
|
executables.
|
|

g:ale_change_sign_column_color *g:ale_change_sign_column_color*
|
|
|
|
|
|
|
|
|
|
Type: |Number|
|
|
|
|
|
Default: `0`
|
|
|
|
|
|
|
|
|
|
When set to `1`, this option will set different highlights for the sign
|
|
|
|
|
column itself when ALE reports problems with a file. This option can be
|
|
|
|
|
combined with |g:ale_sign_column_always|.
|
|
|
|
|
|
|
|
|
|
ALE uses the following highlight groups for highlighting the sign column:
|
|
|
|
|
|
|
|
|
|
`ALESignColumnWithErrors` - Links to `error` by default.
|
|
|
|
|
`ALESignColumnWithoutErrors` - Uses the value for `SignColumn` by default.
|
|
|
|
|
|
|
|
|
|
The sign column color can only be changed globally in Vim. The sign column
|
|
|
|
|
might produce unexpected results if editing different files in split
|
|
|
|
|
windows.
|

g:ale_command_wrapper *g:ale_command_wrapper*
|
|
|
|
|
*b:ale_command_wrapper*
|
|
|
|
|
Type: |String|
|
|
|
|
|
Default: `''`
|
|
|
|
|
|
|
|
|
|
An option for wrapping all commands that ALE runs, for linters, fixers,
|
|
|
|
|
and LSP commands. This option can be set globally, or for specific buffers.
|
|
|
|
|
|
|
|
|
|
This option can be used to apply nice to all commands. For example: >
|
|
|
|
|
|
|
|
|
|
" Prefix all commands with nice.
|
|
|
|
|
let g:ale_command_wrapper = 'nice -n5'
|
|
|
|
|
<
|
|
|
|
|
Use the |ALEInfo| command to view the commands that are run. All of the
|
|
|
|
|
arguments for commands will be put on the end of the wrapped command by
|
|
|
|
|
default. A `%*` marker can be used to spread the arguments in the wrapped
|
|
|
|
|
command. >
|
|
|
|
|
|
|
|
|
|
" Has the same effect as the above.
|
|
|
|
|
let g:ale_command_wrapper = 'nice -n5 %*'
|
|
|
|
|
<
|
|
|
|
|
|
|
|
|
|
For passing all of the arguments for a command as one argument to a wrapper,
|
|
|
|
|
`%@` can be used instead. >
|
|
|
|
|
|
|
|
|
|
" Will result in say: /bin/bash -c 'other-wrapper -c "some command" -x'
|
|
|
|
|
let g:ale_command_wrapper = 'other-wrapper -c %@ -x'
|
|
|
|
|
<
|
|
|
|
|
For commands including `&&` or `;`, only the last command in the list will
|
|
|
|
|
be passed to the wrapper. `&&` is most commonly used in ALE to change the
|
|
|
|
|
working directory before running a command.

The number of milliseconds before ALE will send a request to a language
|
|
|
|
|
server for completions after you have finished typing.

|
|
Type: |List|
|
|
|
|
|
Default: `[]`
|
|
|
|
|
|
|
|
|
|
This option can be set to a list of |String| values for "words" to exclude
|
|
|
|
|
from completion results, as in the words for |complete-items|. The strings
|
|
|
|
|
will be matched exactly in a case-sensitive manner. (|==#|)
|
|
|
|
|
|
|
|
|
|
This setting can be configured in ftplugin files with buffer variables, so
|
|
|
|
|
that different lists can be used for different filetypes. For example: >
|
|
|
|
|
|
|
|
|
|
" In ~/.vim/ftplugin/typescript.vim
|
|
|
|
|
|

|
Type: |Number|
|
|
|
|
|
Default: `50`
|
|
|
|
|
|
|
|
|
|
The maximum number of items ALE will suggest in completion menus for
|
|
|
|
|
automatic completion.
|
|
|
|
|
|
|
|
|
|
Setting this number higher will require more processing time, and may
|
|
|
|
|
suggest too much noise. Setting this number lower will require less
|
|
|
|
|
processing time, but some suggestions will not be included, so you might not
|
|
|
|
|
be able to see the suggestions you want.
|
|
|
|
|
|
|
|
|
|
Adjust this option as needed, depending on the complexity of your codebase
|
|
|
|
|
and your available processing power.

|
|
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|.

Given any integer, this option controls the number of milliseconds before
|
|
|
|
|
ALE will echo a message for a problem near the cursor.
|
|
|
|
|
|
|
|
|
|
The value can be increased to decrease the amount of processing ALE will do

|
|
|
|
|
|
|
|
|
|
This variable defines a message format for echoed messages. The following
|
|
|
|
|
sequences of characters will be replaced.
|
|
|
|
|
|
|
|
|
|
`%s` - replaced with the text for the problem
|
|
|
|
|
`%...code...% `- replaced with the error code
|
|
|
|
|
`%linter%` - replaced with the name of the linter
|
|
|
|
|
`%severity%` - replaced withe severity of the problem
|
|
|
|
|
|
|
|
|
|
The strings for `%severity%` can be configured with the following options.
|
|
|
|
|
|
|
|
|
|
|g:ale_echo_msg_error_str| - Defaults to `'Error'`
|
|
|
|
|
|g:ale_echo_msg_info_str| - Defaults to `'Info'`
|
|
|
|
|
|g:ale_echo_msg_warning_str| - Defaults to `'Warning'`
|
|
|
|
|
|
|
|
|
|
`%code%` is replaced with the error code, and replaced with an empty string
|
|
|
|
|
when there is no error code. Any extra characters between the percent signs
|
|
|
|
|
will be printed when an error code is present. For example, a message like
|
|
|
|
|
`(error code): message` will be printed for `'%(code): %%s'` and simply the
|
|
|
|
|
message will be printed when there is no code.
|
|
|
|
|
|
|
|
|
|
|g:ale_echo_cursor| needs to be set to 1 for messages to be displayed.
|
|
|
|
|
|
|
|
|
|
The echo message format can also be configured separately for each buffer,
|
|
|
|
|
so different formats can be used for differnt languages. (Say in ftplugin
|
|
|
|
|
files.)

When set to `0`, this option will completely disable ALE, such that no
|
|
|
|
|
error checking will be performed, etc. ALE can be toggled on and off with
|
|
|
|
|
the |ALEToggle| command, which changes this option.
|
|
|
|
|
|
|
|
|
|
ALE can be disabled in each buffer by setting `let b:ale_enabled = 0`
|
|
|
|
|
Disabling ALE based on filename patterns can be accomplished by setting
|
|
|
|
|
a regular expression for |g:ale_pattern_options|. For example: >
|
|
|
|
|
|
|
|
|
|
" Disable linting for all minified JS files.
|
|
|
|
|
let g:ale_pattern_options = {'\.min.js$': {'ale_enabled': 0}}
|
|
|
|
|
<
|
|
|
|
|
|
|

When set to 1, ALE will fix files when they are saved.
|
|
|
|
|
|
|
|
|
|
If |g:ale_lint_on_save| is set to 1, files will be checked with linters
|
|
|
|
|
after files are fixed, only when the buffer is open, or re-opened. Changes
|
|
|
|
|
to the file will be saved to the file on disk.
|
|
|
|
|
|
|
|
|
|
Fixing files can be disabled or enabled for individual buffers by setting
|
|
|
|

Default: `1`
|
|
|
|
|
|
|
|
|
|
When set to `1`, ALE will remember the last few commands which were run
|
|
|
|
|
for every buffer which is open. This information can be viewed with the
|
|
|
|
|
|ALEInfo| command. The size of the buffer can be controlled with the
|
|
|
|
|
|g:ale_max_buffer_history_size| option.
|
|
|
|
|
|
|
|
|

Default: `1`
|
|
|
|
|
|
|
|
|
|
When set to `1`, ALE will store the output of commands which have completed
|
|
|
|
|
successfully in the command history, and the output will be displayed when
|
|
|
|
|
using |ALEInfo|.
|
|
|
|
|
|
|
|
|
|
|g:ale_history_enabled| must be set to `1` for this output to be stored or
|
|
|
|
|
printed.
|
|
|
|
|
|
|
|
|
|
Some memory will be consumed by this option. It is very useful for figuring
|
|
|
|
|
out what went wrong with linters, and for bug reports. Turn this option off
|
|
|
|
|
if you want to save on some memory usage.

opened automatically for ALE problems. The default of `10` matches the Vim
|
|
|
|
|
default height.

|
|
|
|
|
|
|
|
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 `always`, `insert`, or `normal`.

|
|
When this option is set to `1`, the |BufWinEnter| 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.
|
|
|
|
|
|
|
|
|
|
The |FileChangedShellPost| and |BufEnter| events will be used to check if
|
|
|
|
|
files have been changed outside of Vim. If a file is changed outside of
|
|
|
|
|
Vim, it will be checked when it is next opened.
|
|
|
|
|
|
|
|
|
|
A |BufWinLeave| event will be used to look for the |E924|, |E925|, or |E926|
|
|
|
|
|
errors after moving from a loclist or quickfix window to a new buffer. If
|
|
|
|
|
prompts for these errors are opened after moving to new buffers, then ALE
|
|
|
|
|
will automatically send the `<CR>` key needed to close the prompt.

Default: `1`
|
|
|
|
|
|
|
|
|
|
This option will cause ALE to run whenever the filetype is changed. A short
|
|
|
|
|
delay will be used before linting will be done, so the filetype can be
|
|
|
|
|
changed quickly several times in a row, but resulting in only one lint
|
|
|
|
|
cycle.
|
|
|
|
|
|
|
|
|
|
If |g:ale_lint_on_enter| is set to `0`, then ALE will not lint a file when
|
|
|
|
|
the filetype is initially set. Otherwise ALE would still lint files when
|
|
|
|
|
buffers are opened, and the option for doing so is turned off.

Default: `1`
|
|

|
|
|
|
|
|
|
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.

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 `never`. 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. This option can also be set to `insert` or `normal`
|
|
|
|
|
to lint when text is changed only in insert or normal mode respectively.

When set to `1` in your vimrc file, this option will cause ALE to run

linters when you leave insert mode.
|
|

|
|
|
|
|

|
ALE will not lint files when you escape insert mode with |CTRL-C| by

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.

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.
|
|
|
|
|
|
|
|
|
|
Passing a list of filetypes is also supported. Say you want to lint
|
|
|
|
|
javascript and css embedded in HTML (using linters that support that).
|
|
|
|
|
You could alias `html` like so:
|
|
|
|
|
|
|
|
|
|
`let g:ale_linter_aliases = {'html': ['html', 'javascript', 'css']}`
|
|
|
|
|
|
|
|
|
|
Note that `html` itself was included as an alias. That is because aliases
|
|
|
|
|
will override the original linters for the aliased filetype.
|
|
|
|
|
|
|
|
|
|
Linter aliases can be configured in each buffer with buffer-local variables.
|
|
|
|
|
ALE will first look for aliases for filetypes in the `b:ale_linter_aliases`
|
|
|
|
|
variable, then `g:ale_linter_aliases`, and then a default Dictionary.
|
|
|
|
|
|
|
|
|
|
`b:ale_linter_aliases` can be set to a |List|, to tell ALE to load the
|
|
|
|
|
linters for specific filetypes for a given buffer. >
|
|
|
|
|
|
|
|
|
|
let b:ale_linter_aliases = ['html', 'javascript', 'css']
|
|
|
|
|
<
|
|
|

No linters will be loaded when the buffer's filetype is empty.

The |g:ale_linters| option sets a |Dictionary| mapping a filetype to a

This option can be used to enable only a particular set of linters for a

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 will be run for unspecified filetypes. All available linters can
|
|
|
|
|
be enabled explicitly for a given filetype by passing the string `'all'`,
|
|
|
|
|
instead of a List. >
|
|
|
|
|
|
|
|
|
|
let g:ale_linters = {'c': 'all'}
|
|
|
|
|
<
|
|
|
|
|
Linters can be configured in each buffer with buffer-local variables. ALE
|
|
|
|
|
will first look for linters for filetypes in the `b:ale_linters` variable,
|
|
|
|
|
then `g:ale_linters`, and then the default Dictionary mentioned above.
|
|
|
|
|
|
|
|
|
|
`b:ale_linters` can be set to a List, or the string `'all'`. When linters
|
|
|
|
|
for two different filetypes share the same name, the first linter loaded
|
|
|
|
|
will be used. Any ambiguity can be resolved by using a Dictionary specifying
|
|
|
|
|
which linter to run for which filetype instead. >
|
|
|
|
|
|
|
|
|
|
" Use ESLint for the buffer if the filetype includes 'javascript'.

|

When set to `1`, only the linters from |g:ale_linters| and |b:ale_linters|
|

given number of signs for any one buffer.
|
|
|
|
|
|
|

When set to `0`, no signs will be set, but sign processing will still be

done, so existing signs can be removed.
|

When set to any other value, no limit will be imposed on the number of signs

|
|
|
|
|
|
|

|
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|)
|
|
|
|
|
|
|
|
|

When set to `'on_save'`, ALE will only open the loclist after buffers have
|
|
|
|
|
been saved. The list will be opened some time after buffers are saved and
|
|
|
|
|
any linter for a buffer returns results.
|
|
|
|
|
|
|
|
|
|
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 when no problems are
|
|
|
|
|
found.
|
|
|
|
|
|
|
|
|
|
The window size can be configured with |g:ale_list_window_size|.
|
|
|
|
|
|
|
|
|
|
Windows can be opened vertically with |g:ale_list_vertical|.
|
|
|
|
|
|
|

|
If you want to close the loclist window automatically when the buffer is

closed, you can set up the following |autocmd| command: >

|
|
|
|

This option maps regular expression patterns to |Dictionary| values for

buffer variables. This option can be set to automatically configure
|
|
|
|
|
different settings for different files. For example: >

See |b:ale_linters| and |b:ale_fixers| for information for those options.
|
|
|
|
|
|
|
|
|
|
Filenames are matched with |match()|, and patterns depend on the |magic|
|
|
|
|
|
setting, unless prefixed with the special escape sequences like `'\v'`, etc.
|
|
|
|
|
The patterns can match any part of a filename. The absolute path of the
|
|
|
|
|
filename will be used for matching, taken from `expand('%:p')`.
|
|
|
|
|
|
|
|
|
|
The options for every match for the filename will be applied, with the
|
|
|
|
|
pattern keys sorted in alphabetical order. Options for `'zebra'` will
|
|
|
|
|
override the options for `'alpha'` for a filename `alpha-zebra`.

problems or hover information if available.
|
|

Problems nearest to the line the mouse cursor is over will be displayed. If

there are no problems to show, and one of the linters is an LSP linter
|

supporting "Hover" information, per |ale-hover|, then brief information

If set to `1`, moving your mouse over documents in Vim will make ALE ask
|
|
|
|
|
`tsserver` or `LSP` servers for information about the symbol where the mouse
|
|
|
|
|
cursor is, and print that information into Vim's echo line. This is an
|
|
|
|
|
option for supporting older versions of Vim which do not properly support
|
|
|
|
|
balloons in an asynchronous manner.
|
|
|
|

If your version of Vim supports the |balloon_show| function, then this

option does nothing meaningful.

When this option is set to `1`, highlights will be set for problems.
|
|
|
|
|
|
|
|

|
ALE will use the following highlight groups for problems:
|
|
|
|
|
|
|
|
|
|
|ALEError| - Items with `'type': 'E'`
|
|
|
|

|ALEInfo.| - Items with `'type': 'I'`
|
|

|
|

|
|
|ALEStyleWarning| - Items with `'type': 'W'` and `'sub_type': 'style'`
|
|
|
|
|
|
|
|
|
|
When |g:ale_set_signs| is set to `0`, the following highlights for entire
|
|
|
|
|
lines will be set.
|
|
|
|
|
|
|
|
|
|
|ALEErrorLine| - All items with `'type': 'E'`

|
|
|
|
|ALEInfoLine| - All items with `'type': 'I'`
|
|
|
|
|
|
|
|
|
|
Vim can only highlight the characters up to the last column in a buffer for
|
|
|
|
|
match highlights, whereas the line highlights when signs are enabled will
|
|
|
|

run to the edge of the screen.

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
|

When this option is set to `1`, the |quickfix| list will be populated with
|
|
|
|
|
any problems which are found by ALE, instead of the |loclist|. The loclist
|
|
|
|
|
will never be populated when this option is on.
|
|
|
|
|
|
|
|
|
|
Problems from every buffer ALE has checked will be included in the quickfix
|
|
|
|
|
list, which can be checked with |:copen|. Problems will be de-duplicated.
|
|
|
|
|
|
|
|
|
|
This feature should not be used in combination with tools for searching for
|
|
|
|
|
matches and commands like |:cfdo|, as ALE will replace the quickfix list
|
|
|
|
|
pretty frequently. If you wish to use such tools, you should populate the

loclist instead.

When this option is set to `1`, the |sign| column will be populated with

|
|
|
|
signs marking where problems appear in the file.
|
|
|
|
|
|
|
|
|
|
ALE will use the following highlight groups for problems:

|
|
|ALEStyleWarningSign| - Items with `'type': 'W'` and `'sub_type': 'style'`
|
|
|
|
|
|
|
|
|
|
In addition to the style of the signs, the style of lines where signs appear
|
|
|
|
|
can be configured with the following highlights:
|
|
|
|
|
|
|
|
|
|
|ALEErrorLine| - All items with `'type': 'E'`
|
|
|
|
|
|ALEWarningLine| - All items with `'type': 'W'`
|
|
|
|
|
|ALEInfoLine| - All items with `'type': 'I'`
|
|
|
|
|
|
|
|
|
|
The markers for the highlights can be customized with the following options:
|

|
|
|
|
|
|
|
When multiple problems exist on the same line, the signs will take
|
|
|
|
|
precedence in the order above, from highest to lowest.
|
|
|
|
|
|
|
|
|
|
To limit the number of signs ALE will set, see |g:ale_max_signs|.

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
|
|
|
|

|
|
|
|
|
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.

|
|
Type: |Dictionary|
|
|
|
|
|
Default: `{}`
|
|
|
|
|
|
|
|
|
|
This option can be set re-map problem types for linters. Each key in the
|
|
|
|
|
|Dictionary| should be the name of a linter, and each value must be a
|
|
|
|
|
|Dictionary| mapping problem types from one type to another. The following
|
|
|
|
|
types are supported:
|
|
|
|
|
|
|
|
|
|
`'E'` - `{'type': 'E'}`
|
|
|
|
|
`'ES'` - `{'type': 'E', 'sub_type': 'style'}`
|
|
|
|
|
`'W'` - `{'type': 'W'}`
|
|
|
|
|
`'WS'` - `{'type': 'W', 'sub_type': 'style'}`
|
|
|
|
|
`'I'` - `{'type': 'I'}`
|
|
|
|
|
|
|
|
|
|
For example, if you want to turn flake8 errors into warnings, you can write
|
|
|
|
|
the following: >
|
|
|
|
|
|
|
|
|
|
let g:ale_type_map = {'flake8': {'ES': 'WS', 'E': 'W'}}
|
|
|
|
|
<
|
|
|
|
|
If you wanted to turn style errors and warnings into regular errors and
|
|
|
|
|
warnings, you can write the following: >
|
|
|
|
|
|
|
|
|
|
let g:ale_type_map = {'flake8': {'ES': 'E', 'WS': 'W'}}
|
|
|
|
|
<
|
|
|
|
|
Type maps can be set per-buffer with `b:ale_type_map`.

files to discover virtulenv directories with.
|
|
|
|
|
|
|
|
|

For directory named `'foo'`, ALE will search for `'foo/bin/activate'`
|
|
|
|
|
(`foo\Scripts\activate\` on Windows) in all directories on and above the
|
|
|
|
|
directory containing the Python file to find virtualenv paths.

When this option is set to `1`, warnings about trailing blank lines will be
|
|
|
|
|
shown.
|
|
|
|
|
|
|
|
|

This option behaves similarly to |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. If warnings are too irritating while editing buffers,
|
|
|
|
|
and you have configured Vim to automatically remove trailing whitespace,
|
|
|
|
|
you can disable these warnings 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.
|
|
|
|
|
|
|
|

|
Type: |String|
|
|
|
|
|
Default: `'node.exe'`
|
|
|
|
|
|
|
|
|
|
This variable is used as the path to the executable to use for executing
|
|
|
|
|
scripts with Node.js on Windows.
|
|
|
|
|
|
|
|
|
|
For Windows, any file with a `.js` file extension needs to be executed with
|
|
|
|
|
the node executable explicitly. Otherwise, Windows could try and open the
|
|
|
|
|
scripts with other applications, like a text editor. Therefore, these
|
|
|
|
|
scripts are executed with whatever executable is configured with this
|
|
|
|
|
setting.

7. Integration Documentation *ale-integrations*
|
|
|
|
|
|
|
|
|
|
Linter and fixer options are documented in individual help files. See the
|
|
|
|
|
table of contents at |ale-contents|.
|
|
|
|
|
|
|
|
|
|
Every option for programs can be set globally, or individually for each
|
|
|
|
|
buffer. For example, `b:ale_python_flake8_executable` will override any
|
|
|
|
|
values set for `g:ale_python_flake8_executable`.
|
|
|
|
|
|
|
|
|
|
*ale-integrations-local-executables*
|
|
|
|
|
|
|
|
|
|
Some tools will prefer to search for locally-installed executables, unless
|
|
|
|
|
configured otherwise. For example, the `eslint` linter will search for
|
|
|
|
|
various executable paths in `node_modules`. The `flake8` linter will search
|
|
|
|
|
for virtualenv directories.
|
|
|
|
|
|
|
|
|
|
If you prefer to use global executables for those tools, set the relevant
|
|
|
|
|
`_use_global` and `_executable` options for those linters. >
|
|
|
|
|
|
|
|
|
|
" Use the global executable with a special name for eslint.
|
|
|
|
|
let g:ale_javascript_eslint_executable = 'special-eslint'
|
|
|
|
|
let g:ale_javascript_eslint_use_global = 1
|
|
|
|
|
|
|
|
|
|
" Use the global executable with a special name for flake8.
|
|
|
|
|
let g:ale_python_flake8_executable = '/foo/bar/flake8'
|
|
|
|
|
let g:ale_python_flake8_use_global = 1

|
|
|
|
2018-06-14 06:31:12 -04:00
|
|
|
|g:ale_use_global_executables| can be set to `1` in your vimrc file to make
|
|
|
|
|
ALE use global executables for all linters by default.
|
|
|
|
|
|
2018-03-31 10:55:20 -04:00
|
|
|
The option |g:ale_virtualenv_dir_names| controls the local virtualenv paths
|
|
|
|
|
ALE will use to search for Python executables.

|
ALEFindReferences *ALEFindReferences*
|
|
|
|
|
|
|
|
|
|
Find references in the codebase for the symbol under the cursor using the
|
|
|
|
|
enabled LSP linters for the buffer. ALE will display a preview window
|
|
|
|
|
containing the results if some references are found.
|
|
|
|
|
|
|
|
|
|
The window can be navigated using the usual Vim navigation commands. The
|
|
|
|
|
Enter key (`<CR>`) can be used to jump to a referencing location, or the `t`
|
|
|
|
|
key can be used to jump to the location in a new tab.
|
|
|
|
|
|
|
|
|
|
You can jump back to the position you were at before going to a reference of

Run ALE once for the current buffer. This command can be used to run ALE
|
|
|
|
|
manually, instead of automatically, if desired.
|
|
|
|
|
|
|
|
|
|
This command will also run linters where `lint_file` is set to `1`, or in
|
|
|
|
|
other words linters which check the file instead of the Vim buffer.
|
|
|
|

Move between warnings or errors in a buffer. ALE will only navigate between
|
|
|
|
|
the errors or warnings it generated, even if both |g:ale_set_quickfix|
|
|
|
|
|
and |g:ale_set_loclist| are set to `0`.
|
|
|
|
|
|
|
|
|
|
`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.
|
|
|
|
|
|
|
|
|
|
`ALEFirst` goes to the first error or warning in the buffer, while `ALELast`
|
|
|
|
|
goes to the last one.
|
|
|
|
|
|
|
|

|
`ALEToggle`, `ALEEnable`, and `ALEDisable` enable or disable ALE linting,
|
|
|
|
|
including all of its autocmd events, loclist items, quickfix items, signs,
|
|
|
|
|
current jobs, etc., globally. Executing any of these commands will change
|
|
|
|
|
the |g:ale_enabled| variable.
|
|
|
|
|
|
|
|
|
|
ALE can be disabled or enabled for only a single buffer with
|
|
|
|
|
`ALEToggleBuffer`, `ALEEnableBuffer`, and `ALEDisableBuffer`. Disabling ALE
|
|
|
|
|
for a buffer will not remove autocmd events, but will prevent ALE from
|
|
|
|
|
checking for problems and reporting problems for whatever buffer the
|
|
|
|
|
`ALEDisableBuffer` or `ALEToggleBuffer` command is executed from. These
|
|
|
|
|
commands can be used for temporarily disabling ALE for a buffer. These
|
|
|
|
|
commands will modify the |b:ale_enabled| variable.
|
|
|
|
|
|
|
|
|
|
ALE linting cannot be enabled for a single buffer when it is disabled
|
|
|
|
|
globally, as disabling ALE globally removes the autocmd events needed to
|
|
|
|
|
perform linting with.
|
|
|
|
|
|
|
|
|
|
The following plug mappings are defined, for conveniently defining keybinds:
|
|
|
|
|
|
|
|
|
|
|ALEToggle| - `<Plug>(ale_toggle)`
|
|
|
|
|
|ALEEnable| - `<Plug>(ale_enable)`
|
|

|
|ALEDisable| - `<Plug>(ale_disable)`
|

|ALEDisableBuffer| - `<Plug>(ale_disable_buffer)`
|
|
|

Show the full linter message for the current line in the preview window.
|
|
|
|
|
This will only have an effect on lines that contain a linter message. The
|
|
|
|
|
preview window can be easily closed with the `q` key.
|
|
|
|
|
|
|
|

ALEInfo *ALEInfo*
|
|
|
|
|
ALEInfoToClipboard *ALEInfoToClipboard*
|
|
|
|
|
|
|
|
|
|
Print runtime information about ALE, including the values of global and
|
|
|
|
|
buffer-local settings for ALE, the linters that are enabled, the commands
|
|
|
|
|
that have been run, and the output of commands.
|
|
|
|
|
|
|
|
|
|
ALE will log the commands that are run by default. If you wish to disable
|
|
|
|
|
this, set |g:ale_history_enabled| to `0`. Because it could be expensive, ALE
|
|
|
|
|
does not remember the output of recent commands by default. Set
|
|
|
|
|
|g:ale_history_log_output| to `1` to enable logging of output for commands.
|
|
|
|
|
ALE will only log the output captured for parsing problems, etc.
|
|
|
|
|
|
|
|
|
|
The command `:ALEInfoToClipboard` can be used to output ALEInfo directly to
|
|
|
|
|
your clipboard. This might not work on every machine.

`ALEReset` will remove all problems reported by ALE for all buffers.
|
|
|
|
|
`ALEResetBuffer` will remove all problems reported for a single buffer.
|
|
|
|
|
|
|
|
|
|
Either command will leave ALE linting enabled, so ALE will report problems
|
|
|
|
|
when linting is performed again. See |ale-lint| for more information.

ALEStopAllLSPs *ALEStopAllLSPs*
|
|
|
|
|

`ALEStopAllLSPs` will close and stop all channels and jobs for all LSP-like
|
|
|
|
|
clients, including tsserver, remove all of the data stored for them, and
|
|
|
|
|
delete all of the problems found for them, updating every linted buffer.
|
|
|
|
|
|
|
|
|

ale#Queue(delay, [linting_flag, buffer_number]) *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
|
|
|
|
|
|
|
|
|
|
An optional `linting_flag` argument can be given. If `linting_flag`
|
|
|
|
|
is `'lint_file'`, then linters where the `lint_file` option is set to `1` will be
|
|
|
|
|
run. Linters with `lint_file` set to `1` are not run by default.
|
|
|
|
|
|
|
|
|
|
An optional `buffer_number` argument can be given for specifying the buffer
|
|
|
|
|
to check. The active buffer (`bufnr('')`) will be checked by default.
|
|
|
|
|
|
|
|
|
|
*ale-cool-down*
|
|
|
|
|
If an exception is thrown when queuing/running ALE linters, ALE will enter
|
|
|
|
|
a cool down period where it will stop checking anything for a short period
|
|
|
|
|
of time. This is to prevent ALE from seriously annoying users if a linter
|
|
|
|
|
is broken, or when developing ALE itself.

ale#engine#CreateDirectory(buffer) *ale#engine#CreateDirectory()*
|
|
|
|
|
|
|
|
|
|
Create a new temporary directory with a unique name, and manage that
|
|
|
|
|
directory with |ale#engine#ManageDirectory()|, so it will be removed as
|
|
|
|
|
soon as possible.
|
|
|
|
|
|
|
|
|
|
It is advised to only call this function from a callback function for
|
|
|
|
|
returning a linter command to run.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
ale#engine#EscapeCommandPart(command_part) *ale#engine#EscapeCommandPart()*
|
|
|
|
|
|
|
|
|
|
Given a |String|, return a |String| with all `%` characters replaced with
|
|
|
|
|
`%%` instead. This function can be used to escape strings which are
|
|
|
|
|
dynamically generated for commands before handing them over to ALE,
|
|
|
|
|
so that ALE doesn't treat any strings with `%` formatting sequences
|
|
|
|
|
specially.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
ale#engine#GetLoclist(buffer) *ale#engine#GetLoclist()*
|
|
|
|
|
|
|
|
|
|
Given a buffer number, this function will return the list of problems
|
|
|
|
|
reported by ALE for a given buffer in the format accepted by |setqflist()|.
|
|
|
|
|
|
|
|
|
|
A reference to the buffer's list of problems will be returned. The list must
|
|
|
|
|
be copied before applying |map()| or |filter()|.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
ale#engine#IsCheckingBuffer(buffer) *ale#engine#IsCheckingBuffer()*
|
|
|
|
|
|
|
|
|
|
Given a buffer number, returns `1` when ALE is busy checking that buffer.
|
|
|
|
|
|
|
|
|
|
This function can be used for status lines, tab names, etc.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
ale#engine#ManageFile(buffer, filename) *ale#engine#ManageFile()*
|
|
|
|
|
|
|
|
|
|
Given a buffer number for a buffer currently running some linting tasks
|
|
|
|
|
and a filename, register a filename with ALE for automatic deletion after
|
|
|
|
|
linting is complete, or when Vim exits.
|
|
|
|
|
|
|
|
|
|
If Vim exits suddenly, ALE will try its best to remove temporary files, but
|
|
|
|
|
ALE cannot guarantee with absolute certainty that the files will be removed.
|
|
|
|
|
It is advised to create temporary files in the operating system's managed
|
|
|
|
|
temporary file directory, such as with |tempname()|.
|
|
|
|
|
|
|
|
|
|
Directory names should not be given to this function. ALE will only delete
|
|
|
|
|
files and symlinks given to this function. This is to prevent entire
|
|
|
|
|
directories from being accidentally deleted, say in cases of writing
|
|
|
|
|
`dir . '/' . filename` where `filename` is actually `''`, etc. ALE instead
|
|
|
|
|
manages directories separetly with the |ale#engine#ManageDirectory| function.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
ale#engine#ManageDirectory(buffer, directory) *ale#engine#ManageDirectory()*
|
|
|
|
|
|
|
|
|
|
Like |ale#engine#ManageFile()|, but directories and all of their contents
|
|
|
|
|
will be deleted, akin to `rm -rf directory`, which could lead to loss of
|
|
|
|
|
data if mistakes are made. This command will also delete any temporary
|
|
|
|
|
filenames given to it.
|
|
|
|
|
|
|
|
|
|
It is advised to use |ale#engine#ManageFile()| instead for deleting single
|
|
|
|
|
files.

ale#fix#registry#Add(name, func, filetypes, desc, [aliases])
|
|
|
|
|
*ale#fix#registry#Add()*
|
|
|
|
|
|
|
|
|
|
Given a |String| `name` for a name to add to the registry, a |String| `func`
|
|
|
|
|
for a function name, a |List| `filetypes` for a list of filetypes to
|
|
|
|
|
set for suggestions, and a |String| `desc` for a short description of
|
|
|
|
|
the fixer, register a fixer in the registry.
|
|
|
|
|
|
|
|
|
|
The `name` can then be used for |g:ale_fixers| in place of the function
|
|
|
|
|
name, and suggested for fixing files.
|
|
|
|
|
|
|
|
|
|
An optional |List| of |String|s for aliases can be passed as the `aliases`
|
|
|
|
|
argument. These aliases can also be used for looking up a fixer function.
|
|
|
|
|
ALE will search for fixers in the registry first by `name`, then by their
|
|
|
|
|
`aliases`.

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, unless the linter is an
|
|
|
|
|
LSP linter. In which case, this argument must not be
|
|
|
|
|
defined, as LSP linters handle diangostics
|
|
|
|
|
automatically. See |ale-lsp-linters|.
|
|
|
|
|
|
|
|
|
|
The keys for each item in the List will be handled in
|
|
|
|
|
the following manner:
|
|
|
|
|
*ale-loclist-format*
|
|
|
|
|
`text` - This error message is required.
|
|
|
|
|
`lnum` - The line number is required. Any strings
|
|
|
|
|
will be automatically converted to numbers by
|
|
|
|
|
using `str2nr()`.
|
|
|
|
|
|
|
|
|
|
Line 0 will be moved to line 1, and lines beyond
|
|
|
|
|
the end of the file will be moved to the end.
|
|
|
|
|
`col` - The column number is optional and will
|
|
|
|
|
default to `0`. Any strings will be automatically
|
|
|
|
|
converted to number using `str2nr()`.
|
|
|
|
|
`end_col` - An optional end column number.
|
|
|
|
|
This key can be set to specify the column problems
|
|
|
|
|
end on, for improved highlighting.
|
|
|
|
|
`end_lnum` - An optional end line number.
|
|
|
|
|
This key can set along with `end_col` for
|
|
|
|
|
highlighting multi-line problems.
|
|
|
|
|
`bufnr` - This key represents the buffer number the
|
|
|
|
|
problems are for. This value will default to
|
|
|
|
|
the buffer number being checked.
|
|
|
|
|
|
|
|
|
|
The `filename` key can be set instead of this key,
|
|
|
|
|
and then the eventual `bufnr` value in the final
|
|
|
|
|
list will either represent the number for an open
|
|
|
|
|
buffer or `-1` for a file not open in any buffer.
|
|
|
|
|
`filename` - An optional filename for the file the
|
|
|
|
|
problems are for. This should be an absolute path to
|
|
|
|
|
a file.
|
|
|
|
|
|
|
|
|
|
Problems for files which have not yet been opened
|
|
|
|
|
will be set in those files after they are opened
|
|
|
|
|
and have been checked at least once.
|
|
|
|
|
|
|
|
|
|
Temporary files in directories used for Vim
|
|
|
|
|
temporary files with `tempname()` will be asssumed
|
|
|
|
|
to be the buffer being checked, unless the `bufnr`
|
|
|
|
|
key is also set with a valid number for some other
|
|
|
|
|
buffer.
|
|
|
|
|
`vcol` - Defaults to `0`.
|
2018-06-14 06:31:12 -04:00
|
|
|
|
|
|
|
|
If set to `1`, ALE will convert virtual column
|
|
|
|
|
positions for `col` and `end_col` to byte column
|
|
|
|
|
positions. If the buffer is changed in-between
|
|
|
|
|
checking it and displaying the results, the
|
|
|
|
|
calculated byte column positions will probably be
|
|
|
|
|
wrong.
|
2018-03-31 10:55:20 -04:00
|
|
|
`type` - Defaults to `'E'`.
|
|
|
|
|
`nr` - Defaults to `-1`.
|
|
|
|
|
|
|
|
|
|
`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.
|
|
|
|
|
|
|
|
|
|
If an empty string is returned from the callback,
|
|
|
|
|
no jobs for linting will be run for that linter.
|
|
|
|
|
This can be used for skipping a linter call,
|
|
|
|
|
say if no configuration file was found.
|
|
|
|
|
|
|
|
|
|
*ale-command-chain*
|
|
|
|
|
`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`.
|
|
|
|
|
|
|
|
|
|
If an empty string is returned for a command in a
|
|
|
|
|
chain, that command in the chain will be skipped,
|
|
|
|
|
and the next function in the chain will be called
|
|
|
|
|
immediately instead. If the last command in a chain
|
|
|
|
|
returns an empty string, then no linting will be
|
|
|
|
|
performed.
|
|
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
Commands in the chain all behave as if `read_buffer`
|
|
|
|
|
is set to `0` by default, except for the last command
|
|
|
|
|
in the chain, which uses the value set for
|
|
|
|
|
`read_buffer` in the root |Dictionary|. Each command
|
|
|
|
|
in the chain can also provide a `read_buffer` key
|
|
|
|
|
to override these values.
|
|
|
|
|
See the `read_buffer` description for more
|
|
|
|
|
information.
|
|
|
|
|
|
|
|
|
|
`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.
|
|
|
|
|
|
|
|
|
|
`read_buffer` A |Number| (`0` or `1`) indicating whether a command
|
|
|
|
|
should read the Vim buffer as input via stdin. This
|
|
|
|
|
option is set to `1` by default, and can be disabled
|
|
|
|
|
if a command manually reads from a temporary file
|
|
|
|
|
instead, etc.
|
|
|
|
|
|
|
|
|
|
*ale-lint-file*
|
|
|
|
|
`lint_file` A |Number| (`0` or `1`) indicating whether a command
|
|
|
|
|
should read the file instead of the Vim buffer. This
|
|
|
|
|
option can be used for linters which must check the
|
|
|
|
|
file on disk, and which cannot check a Vim buffer
|
|
|
|
|
instead.
|
|
|
|
|
|
|
|
|
|
Linters set with this option will not be run as a
|
|
|
|
|
user types, per |g:ale_lint_on_text_changed|. Linters
|
|
|
|
|
will instead be run only when events occur against
|
|
|
|
|
the file on disk, including |g:ale_lint_on_enter|
|
|
|
|
|
and |g:ale_lint_on_save|. Linters with this option
|
|
|
|
|
set to `1` will also be run when linters are run
|
|
|
|
|
manually, per |ALELintPost-autocmd|.
|
|
|
|
|
|
|
|
|
|
When this option is set to `1`, `read_buffer` will
|
|
|
|
|
be set automatically to `0`. The two options cannot
|
|
|
|
|
be used together.
|
|
|
|
|
|
|
|
|
|
*ale-lsp-linters*
|
|
|
|
|
`lsp` A |String| for defining LSP (Language Server Protocol)
|
|
|
|
|
linters.
|
|
|
|
|
|
|
|
|
|
This argument may be omitted or `''` when a linter
|
|
|
|
|
does not represent an LSP linter.
|
|
|
|
|
|
|
|
|
|
When this argument is set to `'stdio'`, then the
|
|
|
|
|
linter will be defined as an LSP linter which keeps a
|
|
|
|
|
process for a language server runnning, and
|
|
|
|
|
communicates with it directly via a |channel|.
|
|
|
|
|
|
2018-06-14 06:31:12 -04:00
|
|
|
When this argument is not empty, only one of either
|
|
|
|
|
`language` or `language_callback` must be defined,
|
|
|
|
|
and `project_root_callback` must be defined.
|
2018-03-31 10:55:20 -04:00
|
|
|
|
|
|
|
|
LSP linters handle diagnostics automatically, so
|
|
|
|
|
the `callback` argument must not be defined.
|
|
|
|
|
|
2018-06-14 06:31:12 -04:00
|
|
|
An optional `completion_filter` callback may be
|
|
|
|
|
defined for filtering completion results.
|
|
|
|
|
|
|
|
|
|
An optional `initialization_options` or
|
|
|
|
|
`initialization_options_callback` may be defined to
|
|
|
|
|
pass initialization options to the LSP.
|
|
|
|
|
|
|
|
|
|
`project_root_callback` A |String| or |Funcref| for a callback function
|
2018-03-31 10:55:20 -04:00
|
|
|
accepting a buffer number. A |String| should be
|
|
|
|
|
returned representing the path to the project for the
|
|
|
|
|
file being checked with the language server. If an
|
|
|
|
|
empty string is returned, the file will not be
|
|
|
|
|
checked at all.
|
|
|
|
|
|
|
|
|
|
This argument must only be set if the `lsp` argument
|
|
|
|
|
is also set to a non-empty string.
|
|
|
|
|
|
2018-06-14 06:31:12 -04:00
|
|
|
`language` A |String| representing the name of the language
|
|
|
|
|
being checked. This string will be sent to the LSP to
|
|
|
|
|
tell it what type of language is being checked.
|
|
|
|
|
|
|
|
|
|
This argument must only be set if the `lsp` argument
|
|
|
|
|
is also set to a non-empty string.
|
|
|
|
|
|
2018-03-31 10:55:20 -04:00
|
|
|
`language_callback` A |String| or |Funcref| for a callback function
|
|
|
|
|
accepting a buffer number. A |String| should be
|
|
|
|
|
returned representing the name of the language being
|
|
|
|
|
checked.
|
|
|
|
|
|
2018-06-14 06:31:12 -04:00
|
|
|
This option can be used instead of `language` if a
|
|
|
|
|
linter can check multiple languages.
|
|
|
|
|
|
|
|
|
|
`completion_filter` A |String| or |Funcref| for a callback function
|
|
|
|
|
accepting a buffer number and a completion item.
|
|
|
|
|
|
|
|
|
|
The completion item will be a |Dictionary| following
|
|
|
|
|
the Language Server Protocol `CompletionItem`
|
|
|
|
|
interface as described in the specification,
|
|
|
|
|
available online here:
|
|
|
|
|
https://microsoft.github.io/language-server-protocol
|
2018-03-31 10:55:20 -04:00
|
|
|
|
|
|
|
|
`aliases` A |List| of aliases for the linter name.
|
|
|
|
|
|
|
|
|
|
This argument can be set with alternative names for
|
|
|
|
|
selecting the linter with |g:ale_linters|. This
|
|
|
|
|
setting can make it easier to guess the linter name
|
|
|
|
|
by offering a few alternatives.
|
|
|
|
|
|
2018-06-14 06:31:12 -04:00
|
|
|
`initialization_options` A |Dictionary| of initialization options for LSPs.
|
|
|
|
|
This will be fed (as JSON) to the LSP in the
|
|
|
|
|
initialize command.
|
|
|
|
|
|
|
|
|
|
`initialization_options_callback`
|
|
|
|
|
A |String| or |Funcref| for a callback function
|
|
|
|
|
accepting a buffer number. A |Dictionary| should be
|
|
|
|
|
returned for initialization options to pass the LSP.
|
|
|
|
|
This can be used in place of `initialization_options`
|
|
|
|
|
when more complicated processing is needed.
|
|
|
|
|
|
2018-03-31 10:55:20 -04:00
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
If temporary files or directories are created for commands run with
|
|
|
|
|
`command_callback` or `command_chain`, then these tempoary files or
|
|
|
|
|
directories can be managed by ALE, for automatic deletion.
|
|
|
|
|
See |ale#engine#ManageFile()| and |ale#engine#ManageDirectory| for more
|
|
|
|
|
information.
|
|
|
|
|
|
|
|
|
|
*ale-command-format-strings*
|
|
|
|
|
|
|
|
|
|
All command strings will be formatted for special character sequences.
|
|
|
|
|
Any substring `%s` will be replaced with the full path to the current file
|
|
|
|
|
being edited. This format option can be used to pass the exact filename
|
|
|
|
|
being edited to a program.
|
|
|
|
|
|
|
|
|
|
For example: >
|
|
|
|
|
'command': 'eslint -f unix --stdin --stdin-filename %s'
|
|
|
|
|
<
|
|
|
|
|
Any substring `%t` will be replaced with a path to a temporary file. Merely
|
|
|
|
|
adding `%t` will cause ALE to create a temporary file containing the
|
|
|
|
|
contents of the buffer being checked. All occurrences of `%t` in command
|
|
|
|
|
strings will reference the one temporary file. The temporary file will be
|
|
|
|
|
created inside a temporary directory, and the entire temporary directory
|
|
|
|
|
will be automatically deleted, following the behaviour of
|
|
|
|
|
|ale#engine#ManageDirectory|. This option can be used for some linters which
|
|
|
|
|
do not support reading from stdin.
|
|
|
|
|
|
|
|
|
|
For example: >
|
|
|
|
|
'command': 'ghc -fno-code -v0 %t',
|
|
|
|
|
<
|
|
|
|
|
The character sequence `%%` can be used to emit a literal `%` into a
|
|
|
|
|
command, so literal character sequences `%s` and `%t` can be escaped by
|
|
|
|
|
using `%%s` and `%%t` instead, etc.
|
|
|
|
|
|
|
|
|
|
If a callback for a command generates part of a command string which might
|
|
|
|
|
possibly contain `%%`, `%s`, or `%t` where the special formatting behaviour
|
|
|
|
|
is not desired, the |ale#engine#EscapeCommandPart()| function can be used to
|
|
|
|
|
replace those characters to avoid formatting issues.
|
|
|

|
|
|
*ale-linter-loading-behaviour*
|
|
|
|
|
|
|
|
|
|
Linters for ALE will be loaded by searching |runtimepath| in the following
|
|
|
|
|
format: >
|
|
|
|
|
|
|
|
|
|
ale_linters/<filetype>/<linter_name>.vim
|
|
|
|
|
<
|
|
|
|
|
Any linters which exist anywhere in |runtimepath| with that directory
|
|
|
|
|
structure will be automatically loaded for the matching |filetype|. Filetypes
|
|
|
|
|
containing `.` characters will be split into individual parts, and files
|
|
|
|
|
will be loaded for each filetype between the `.` characters.
|
|
|
|
|
|
2018-06-14 06:31:12 -04:00
|
|
|
Linters can be defined from vimrc and other files as long as this function
|
|
|
|
|
is loaded first. For example, the following code will define a Hello World
|
|
|
|
|
linter in vimrc in Vim 8: >
|
|
|
|
|
|
|
|
|
|
" Plugins have to be loaded first.
|
|
|
|
|
" If you are using a plugin manager, run that first.

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-separated 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-separated filetypes are broken up into their
|
|
|
|
|
components.

ale#linter#PreventLoading(filetype) *ale#linter#PreventLoading()*

|
|
|
|
|
|
|
|
Given a `filetype`, prevent any more linters from being loaded from
|
|
|
|
|
|runtimepath| for that filetype. This function can be called from vimrc or
|
|
|
|
|
similar to prevent ALE from loading linters.

ale#statusline#Count(buffer) *ale#statusline#Count()*
|
|
|
|
|
|
|
|
|
|
Given the number of a buffer which may have problems, return a |Dictionary|
|
|
|
|
|
containing information about the number of problems detected by ALE. The
|
|
|
|
|
following keys are supported:
|
|
|
|
|
|
|
|
|
|
`error` -> The number of problems with type `E` and `sub_type != 'style'`
|
|
|
|
|
`warning` -> The number of problems with type `W` and `sub_type != 'style'`
|
|
|
|
|
`info` -> The number of problems with type `I`
|
|
|
|
|
`style_error` -> The number of problems with type `E` and `sub_type == 'style'`
|
|
|
|
|
`style_warning` -> The number of problems with type `W` and `sub_type == 'style'`
|
|
|
|
|
`total` -> The total number of problems.

|
b:ale_linted *b:ale_linted*
|
|
|
|
|
|
|
|
|
|
`b:ale_linted` is set to the number of times a buffer has been checked by
|
|
|
|
|
ALE after all linters for one lint cycle have finished checking a buffer.
|
|
|
|
|
This variable may not be defined until ALE first checks a buffer, so it
|
|
|
|
|
should be accessed with |get()| or |getbufvar()|. For example: >
|
|
|
|
|
|
|
|
|
|
" Print a message indicating how many times ALE has checked this buffer.
|
|
|
|
|
echo 'ALE has checked this buffer ' . get(b:, 'ale_linted') . ' time(s).'
|
|
|
|
|
" Print 'checked' using getbufvar() if a buffer has been checked.
|
|
|
|
|
echo getbufvar(bufnr(''), 'ale_linted', 0) > 0 ? 'checked' : 'not checked'

ALELintPre *ALELintPre-autocmd*

ALEFixPre *ALEFixPre-autocmd*

|
|
|

ALEFixPost *ALEFixPost-autocmd*
|
|
|
|
|
|
|
|
|
|
These |User| autocommands are triggered before and after every lint or fix
|
|
|
|
|
cycle. They can be used to update statuslines, send notifications, etc.
|
|
|
|
|
The autocmd commands are run with |:silent|, so |:unsilent| is required for
|
|
|
|
|
echoing messges.
|
|
|
|
|
|
|
|
|
|
For example to change the color of the statusline while the linter is
|
|
|
|
|
running:
|
|
|
|
|
>
|
|
|
|
|
augroup ALEProgress
|
|
|
|
|
autocmd!
|
|
|
|
|
autocmd User ALELintPre hi Statusline ctermfg=darkgrey
|
|
|
|
|
autocmd User ALELintPOST hi Statusline ctermfg=NONE
|
|
|
|
|
augroup end
|
|
|
|
|
<
|
|
|
|
|
Or to display the progress in the statusline:
|
|
|
|
|
>
|
|
|
|
|
let s:ale_running = 0
|
|
|
|
|
let l:stl .= '%{s:ale_running ? "[linting]" : ""}'
|
|
|
|
|
augroup ALEProgress
|
|
|
|
|
autocmd!
|
|
|
|
|
autocmd User ALELintPre let s:ale_running = 1 | redrawstatus
|
|
|
|
|
autocmd User ALELintPost let s:ale_running = 0 | redrawstatus
|
|
|
|
|
augroup end

ALEJobStarted *ALEJobStarted-autocmd*
|
|
|
|
|
|
|
|
|
|
This |User| autocommand is triggered immediately after a job is successfully
|
|
|
|
|
run. This provides better accuracy for checking linter status with
|
|
|
|
|
|ale#engine#IsCheckingBuffer()| over |ALELintPre-autocmd|, which is actually
|
|
|
|
|
triggered before any linters are executed.
