If you are an avid Emacs user you probably already know about helm, a completion assistant similar, at glance, to
idobut a lot, lot more powerful.
helmpower comes, in my opinion, by two particular properties:
- the incremental completion via patterns
- the huge configuration available.
helmsearching for the possible completions for you. The package provides a great flexibility via the configuration parameters, as well explained here. My personal, minimal, helm configuration so far is the following:
As you can see, my configuration is pretty much straightforward. One thing I like the most about
(require 'helm-config) ;; activate helm always! (helm-mode 1) ;; helm complete commands via M-x (global-set-key (kbd "M-x") 'helm-M-x) ;; frankly, using tab for actions is annoying, change the behaviour (define-key helm-map (kbd "<tab>") 'helm-execute-persistent-action) ; rebind tab to do persistent action (define-key helm-map (kbd "C-i") 'helm-execute-persistent-action) ; make TAB works in terminal (define-key helm-map (kbd "C-z") 'helm-select-action) ; list actions using C-z ;; resize the buffer depending on the number of completions (helm-autoresize-mode t) ;; helm complete find files, use ack as grep command in find-files (global-set-key (kbd "C-x C-f") 'helm-find-files) (setq helm-grep-default-command "ack-grep -Hn --no-group --no-color %e %p %f" helm-grep-default-recurse-command "ack-grep -H --no-group --no-color %e %p %f") ; semantic (semantic-mode 1) (setq helm-semantic-fuzzy-match t helm-imenu-fuzzy-match t)
helmis the capability to interact with
semantic, that for a developer like me is a huge improvement.
