No cppcheck output (again)

[KMickle]

Good day.

I need assistance with setting up ALE to work with cppcheck. The tool is enabled, successfully detected and run. But there is no output in the Neovim interface whatsoever. Other linters (namely, clangd and cc) do work.

The former threads about cppcheck plugin malfunction no longer apply: the template string in the 'cppcheck' handler is relevant ( #2891 ) and properly escaped ( #3579 ).

I do not have enough Vim/ALE expertise to diagnose the issue. So, I would be grateful for any help on the subject.

,vimrc:

let g:ale_cursor_detail = 1
let g:ale_lsp_suggestions = 1
let g:ale_linters = {'c': ['cppcheck']}
let g:ale_c_cppcheck_options = '--enable=style'
