To limit the number of signs ALE will set, see |g:ale_max_signs|.
g:ale_shell *g:ale_shell*
Type: |String|
Default: not set
Override the shell used by ALE for executing commands. ALE uses 'shell' by
default, but falls back in `/bin/sh` if the default shell looks like `fish`
or `pwsh`, which are not compatible with all of the commands run by ALE. The
shell specified with this option will be used even if it might not work in
all cases.
For Windows, ALE uses `cmd` when this option isn't set. Setting this option
will apply shell escaping to the command string, even on Windows.
NOTE: Consider setting |g:ale_shell_arguments| if this option is defined.
g:ale_shell_arguments *g:ale_shell_arguments*
Type: |String|
Default: not set
This option specifies the arguments to use for executing a command with a
custom shell, per |g:ale_shell|. If this option is not set, 'shellcmdflag'
will be used instead.

g:ale_shell *g:ale_shell*
Type: |String|
Default: not set
This variable is used to determine which shell ale will use to execute
commands. By default this variable is undefined, meaning that ALE will use
it's default behavior. Which is to run shells via the shell determined by
the `&shell` vim variable, with the arguments `&shellcmdflag`. Ale will fall
back to using `/bin/sh`if it detects the underlying `&shell`is either `fish`
or `pwsh`. However, if you set this variable ALE will no longer fall back to
other shells, meaning if you wanted to use `fish` you could do so via this
option. For example if `$SHELL == '/bin/bash'`, but you want to use zsh,
set `g:ale_shell = '/bin/zsh'.
Please note - if you are using this option you should consider additionally
setting `g:ale``g:ale_shell_arguments` since the default values for that
option might be incompatable with the newly set shell.
g:ale_shell_arguments *g:ale_shell_arguments*
Type: |String|
Default: not set
This variable is used to determine what commands vim will pass to the shell
to execute it's commands. If this command is not set, but g:ale_shell is
set, ale will use `&shellcmdflag` as command arguments.
