It is worth reading the documentation for every option. You should configure
which events ALE will use before ALE is loaded, so it can optimize which

The |FileChangedShellPost| and |BufEnter| events will be used to check if

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.

This option will cause ALE to run when the filetype for a file is changed

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: `always`
Default: `'always'`
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.
This option controls how ALE will check your files as you make changes.
The following values can be used.
`'always'`, `'1'`, or `1` - Check buffers on |TextChanged| or |TextChangedI|.
`'normal'` - Check buffers only on |TextChanged|.
`'insert'` - Check buffers only on |TextChangedI|.
`'never'`, `'0'`, or `0` - Never check buffers on changes.
ALE will check buffers after a short delay, with a timer which resets on
each change. The delay can be configured by adjusting the |g:ale_lint_delay|
variable.
You should set this setting once before ALE is loaded, and restart Vim if
you want to change your preferences. See |ale-lint-settings-on-startup|.
