ALE automatic completion will not work when 'paste' is active. Only set
'paste' when you are copy and pasting text into your buffers.
+ALE automatic completion will interfere with default insert completion with
+`CTRL-N` and so on (|compl-vim|). You can write your own keybinds and a
+function in your |vimrc| file to force insert completion instead, like so: >
+
+ function! SmartInsertCompletion() abort
+ " Use the default CTRL-N in completion menus
+ if pumvisible()
+ return "\<C-n>"
+ endif
+
+ " Exit and re-enter insert mode, and use insert completion
+ return "\<Esc>a\<C-n>"

ALE provides an 'omnifunc' function |ale#completion#OmniFunc| for triggering
completion manually with CTRL-X CTRL-O. |i_CTRL-X_CTRL-O| >

+You can write your own completion function and fallback on other methods of
+completion by checking if there are no results that ALE can determine. For
+example, for Python code, you could fall back on the `python3complete`
+function. >

+ function! TestCompletionFunc(findstart, base) abort
+ let l:result = ale#completion#OmniFunc(a:findstart, a:base)
+
+ " Check if ALE couldn't find anything.
+ if (a:findstart && l:result is -3)

+ " Defer to another omnifunc if ALE couldn't find anything.

ALE will only suggest so many possible matches for completion. The maximum
number of items can be controlled with |g:ale_completion_max_suggestions|.
