Indentation of groovy style method parameters in emacs -

i using emacs groovy electric mode (installed outlined here). relevant parts (i think) of .emacs file given @ end of question.

the current behaviour getting indenting, type, is:

def someobject = new something(     param1 

everything how @ point, type ':' character, becomes:

def someobject = new something( param1: 

i want param/value pairs (and follow) remain indented 1 level, before, e.g.:

def someobject = new something(     param1: val1,     param2: val2 ) 

.emacs excerpt:

(electric-indent-mode t)  (setq-default tab-width 4) (setq-default indent-tabs-mode nil) (setq indent-line-function 'insert-tab) (setq tabify nil) (setq-default c-basic-offset 4) (delete-selection-mode 1) (set-default-font "-apple-bitstream_vera_sans_mono-medium-normal-normal-*-*-*-*-*-m-0-iso10646-1") (setq load-path (cons "~/.emacs.d/" load-path)) (add-to-list 'custom-theme-load-path "~/.emacs.d/themes/")  (setq whitespace-action '(auto-cleanup)) ;; automatically clean bad whitespace (setq whitespace-style '(trailing space-before-tab indentation empty space-after-tab)) ;; show bad whitespace ;;; delete trailing whitespace (add-hook 'before-save-hook 'delete-trailing-whitespace)  ;;; turn on syntax highlighting (global-font-lock-mode 1)  ;;; use groovy-mode when file ends in .groovy or has #!/bin/groovy @ start (autoload 'groovy-mode "groovy-mode" "major mode editing groovy code." t) (add-to-list 'auto-mode-alist '("\\.groovy\\'" . groovy-mode)) (add-to-list 'interpreter-mode-alist '("groovy" . groovy-mode))  ;;; make groovy mode electric default. (add-hook 'groovy-mode-hook           (lambda ()             (require 'groovy-electric)             (groovy-electric-mode))) 

edit: regarding @ataylor 's suggestion below, have tried both:

(add-hook 'groovy-mode-hook           '(lambda ()              (require 'groovy-electric)              (groovy-electric-mode)))  (add-hook 'groovy-mode-hook '(c-set-offset 'label 4)) 

and

(add-hook 'groovy-mode-hook           '(lambda ()              (require 'groovy-electric)              (groovy-electric-mode)              (c-set-offset 'label 4))) 

neither of work want. correct spot?

groovy mode treating these types of parameters labels, case statement labels , used feature inherited java allows break statements specify target.

you can override indentation adding hook:

(add-hook 'groovy-mode-hook           (lambda ()             (c-set-offset 'label 4)))
