I have been trying to start with emacs for doing node.js based project development.
I have not been able to set up my emacs for this. It has more become like a trial and error kind of black box leading to frustation. Can you help me in setting this up :
I installed plugins with M-x package-install
My emacs file looks like :
;; added for javascript -------
; Use dictionaries by default
(setq-default ac-sources (add-to-list 'ac-sources 'ac-source-dictionary))
(global-auto-complete-mode t)
; Start auto-completion after 2 characters of a word
(setq ac-auto-start 2)
; case sensitivity is important when finding matches
(setq ac-ignore-case nil)
(require 'yasnippet)
;; now enable the yasnippet for snippets
(yas-global-mode 1)
;; set the snippets directory
(setq yas-snippet-dirs
'( "~/.emacs.d/plugins_old/yasnippet/yasmate/snippets" ;; the yasmate collection
"~/.emacs.d/plugins_old/yasnippet/snippets" ;; the snippet collection
"~/.emacs.d/elpa/yasnippet/snippets" ;; the default collection
))
(ac-set-trigger-key "TAB")
(ac-set-trigger-key "<tab>")
;; (define-key yas-minor-mode-map (kbd "TAB") 'yas-expand)
;; (define-key yas-minor-mode-map (kbd "<tab>") 'yas-expand)
;; (setq yas-trigger-key "")
;; (setq yas-next-field-key "")
;; (setq yas-prev-field-key "")
;; Let's have snippets in the auto-complete dropdown
(add-to-list 'ac-sources 'ac-source-yasnippet)
;; adding lint node
;; (add-to-list 'load-path "~/.emacs.d/plugins_old/lintnode")
;; finally followed this : http://www.emacswiki.org/emacs/FlymakeJavaScript to install jslint in emacs
(require 'flymake-jslint)
(add-hook 'js-mode-hook 'flymake-jslint-load)
;; Make sure we can find the lintnode executable
;; (setq lintnode-location "~/.emacs.d/plugins_old/lintnode")
;; JSLint can be... opinionated
;; (setq lintnode-jslint-excludes (list 'nomen 'undef 'plusplus 'onevar 'white))
;; Start the server when we first open a js file and start checking
;; (add-hook 'js-mode-hook
;; (lambda ()
;; (lintnode-hook)))
;; added red cursor for wrong lint node errors
(require 'flymake-cursor)
;; fold the functions
( add-hook 'js-mode-hook
(lambda ()
;; Scan the file for nested code blocks
(imenu-add-menubar-index)
;; Activate the folding mode
(hs-minor-mode t)))
;; Show-hide
(global-set-key (kbd "") 'hs-show-block)
(global-set-key (kbd "") 'hs-show-all)
(global-set-key (kbd "") 'hs-hide-block)
(global-set-key (kbd "") 'hs-hide-all)
;; repl for javascript
(require 'js-comint)
;; Use node as our repl
(setq inferior-js-program-command "node")
(setq inferior-js-mode-hook
(lambda ()
;; We like nice colors
(ansi-color-for-comint-mode-on)
;; Deal with some prompt nonsense
(add-to-list 'comint-preoutput-filter-functions
(lambda (output)
(replace-regexp-in-string ".*1G\.\.\..*5G" "..."
(replace-regexp-in-string ".*1G.*3G" ">" output))))))
;; -----------------------------
This is the part that i recently added for setting up the environment ; you may see a lot of commented code which shows i tried this or that from everywhere. I followed mostly : deadpansincerity and then tried lately with turnongtx
What i mostly want is yasnippet and autocomplete with jslint to work ? Other features can be addons, but i am struggling for two days with these only.
My emacs version is 24.3.1 where many things do break.
I observed that after 1 complete one day of trial and error, yasnippet started working but after restart of emacs it is not working. It means that i might have done some right things during that emacs session with reloading the .emacs file. but again i do not know what is happening where.
When i open any js file and write if and hit TAB nothing happens.
Also, doing M-x yas-expand after writing if nothing happens.
but a message do come, You can run the command "yas-expand" with TAB, but this too happens sometimes.
I remember that at one point of time doing any thing above was showing the if-expanded yesterday.
The good thing is that my jslint is working. I installed it using npm and added the flymake. :) Also i can use comint nodejs repl :)
Any help would be appreciated.
My complete emacs file is here my emacs
Use yas-global-mode after you set yas-snippet-dirs. Otherwise you have to use yas-reload-all, which is what happened.
Follow the example here
