helm-M-x fuzzy not working (only match if provide proper prefix)

Question

I set helm-M-x-fuzzy-match to true, but it is not working as I want.

For example, if I type log:

I expect it to show clm/toggle-command-log-buffer as well.

Check out https://github.com/syl20bnr/spacemacs/issues/13100.

There was a breaking change in Helm which removed the fuzzy- variables you defined.

In place, you have to set the following variables in your init.el:

For emacs27:

(setq helm-completion-style 'emacs)
(setq completion-styles '(flex))

For emacs26:

(setq helm-completion-style 'emacs)
(setq completion-styles '(helm-flex))

Hope that helps anyone else with the same issue.
