@ -55,50 +55,59 @@ tools will be run in combination, so they can be complementary.
Keep the table rows sorted alphabetically by the language name,
and the tools in the tools column sorted alphabetically by the tool
name. That seems to be the fairest way to arrange this table.
Remember to also update doc/ale.txt, which has a similar list with different
formatting.

3. Global Options *ale-options*
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 ccode 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 ccode 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.

4. Fixing Problems *ale-fix*
ALE can fix problems with files with the |ALEFix| command. When |ALEFix| is
run, 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.
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.
*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 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. Completion *ale-completion*
ALE offers some limited support for automatic completion of code while you
type. Completion is only supported via Language Server Protocol servers which
ALE can connect to for linting, which can offer good built-in support for
suggesting completion information. ALE will only suggest symbols for
completion for LSP linters that are enabled.
NOTE: At the moment, only `tsserver` for TypeScript code is supported for
completion.
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|.
