for different filetypes with the `g:ale_fixers` variable. See `:help ale-fix`.

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 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 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.
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.
