Access Emacs command interpreter prompts through helm.
You can bind this as follows in .emacs:
(add-hook 'comint-mode-hook
(lambda ()
(define-key comint-mode-map (kbd "M-s f") 'helm-comint-prompts-all)))
Or as another example you can see how Spacemacs uses it in 'spacemacs/helm-shell-history'.
helm-comint is written by Pierre Neidhardt mail@ambrevar.xyz. Removed from helm v3.9.5 core and exists as a user contrib package.
