Grails.el is an Emacs minor mode that allows an easy navigation of Grails projects.
Grails.el allows you to fast open a domain class, a controller, a service or a view providing customized open functions for each Grails file type. Now with autocompletion and history support.
Moreover it can jump from the current domain|controller|service to the related domain|controller|service. You can also jump to the Bootstrap and UrlMappings file. And yes, you can jump from the current controller action to the related view NEW.
This minor mode doesn't have any external dependencies and works nicely with Grails 2 and Grails 3 projects.
Available functions and default key bindings Function Default key binding Effect grails-domain-from-file
C-c - d Open the Domain class related to the current file (e.g. if current buffer is controllers/UserController.groovy, it opens domain/User.groovy grails-controller-from-file C-c - c Open the Controller class related to the current file (e.g. if current buffer is domain/User.groovy, it opens controllers/UserController.groovy grails-service-from-file C-c - s Open the Service class related to the current file (e.g. if current buffer is controllers/UserController.groovy, it opens services/UserService.groovy grails-view-from-context C-c - v v Open the view related to the current controller action grails-view-from-cursor C-c - v w Open the view related to the current controller, with name equals to the current word (cursor) grails-urlmappings-file C-c - u Open the UrlMappings file grails-bootstrap-file C-c - b Open the Bootstrap file grails-domain-from-name C-c - n d Open a find file prompt inside grails-app/domain/ grails-controller-from-name C-c - n c Open a find file prompt inside grails-app/controllers/ grails-service-from-name C-c - n s Open a find file prompt inside grails-app/services/ grails-view-from-name C-c - n v Open a find file prompt inside grails-app/views/ grails-version C-c - p Show grails project properties (only grails version by now) Class names with packages and jump features
Class names with packages are fully supported. E.g.:
C-c - c (if current buffer is domain/my/package/User.groovy) will open controllers/my/package/UserController.groovyEmacs key binding convention say that a minor mode can only define bindings like C-c punctuation_char other_char ... also avoiding {, }, <, >, : or ; as the first punctuation char. So, the default bindings for grails.el starts always with the sequence C-c -. If you want shorter bindings, and I'm sure you want them, just read below.
This mode expose a grails-key-map variable that you can use to customize default key bindings available only when grails mode is active. Just add to your .emacs file a define-key for every command that you want to bind to a custom key binding.
E.g.:
;; your .emacs file
(require 'grails) ;; do not add this if you've installed it from melpa
;; jump commands
(define-key grails-key-map (kbd "C-c d") 'grails-domain-from-file)
(define-key grails-key-map (kbd "C-c c") 'grails-controller-from-file)
(define-key grails-key-map (kbd "C-c s") 'grails-service-from-file)
(define-key grails-key-map (kbd "C-c v") 'grails-view-from-context)
(define-key grails-key-map (kbd "C-c w") 'grails-view-from-cursor)
(define-key grails-key-map (kbd "C-c u") 'grails-urlmappings-file)
(define-key grails-key-map (kbd "C-c b") 'grails-bootstrap-file)
;; find file commands
;; equals to C-x C-f called from /your/project/grails-app/domain/
(define-key grails-key-map (kbd "C-c C-f d") 'grails-domain-from-name)
;; equals to C-x C-f called from /your/project/grails-app/controllers/
(define-key grails-key-map (kbd "C-c C-f c") 'grails-controller-from-name)
;; equals to C-x C-f called from /your/project/grails-app/services/
(define-key grails-key-map (kbd "C-c C-f s") 'grails-service-from-name)
;; equals to C-x C-f called from /your/project/grails-app/views/
(define-key grails-key-map (kbd "C-c C-f v") 'grails-view-from-name)
;; show Grails project properties (only version by now)
(define-key grails-key-map (kbd "C-c p") 'grails-version)
Available commands are listed in the table above.
Copy this file to to some location in your Emacs load path. Then add (require 'grails) to your Emacs initialization (.emacs, init.el, or something):
To auto enable grails minor mode, create a .dir-locals.el file in the root of the grails project with this configuration:
In this way, the grails minor mode will be always active inside your project tree.
The first time that this code is executed, Emacs will show a security prompt: answer "!" to mark code secure and save your decision (a configuration line is automatically added to your .emacs file).
This is the suggested default configuration.
In order to have grails minor mode auto enabled only when using certain modes, place this inside your .dir-locals.el:
((groovy-mode (grails . 1))
(html-mode (grails . 1))
(java-mode (grails . 1)))
In this way, the grails minor mode will be auto enabled when any of these major modes are loaded (only in this directory tree - the project tree) (you can attach it to other modes if you want).
