requirejs-mode

Improved javascript AMD dependencies management for the one true editor.

See it in action

Installation

Packages are available in the marmalade and MELPA repositories, so if you use ELPA:

M-x package-install requirejs-mode

Otherwise, make sure you put the requirejs-mode.el in your load path.

Then in your init.el file.

(require 'requirejs-mode)

If you would like to automatically load requireJs mode when editing javascript, you can put the following in your init.el. Replace js2-mode-hook by javascript-mode-hook if you don't use js2-mode.

(add-hook 'js2-mode-hook (lambda () (requirejs-mode)))

Features

Importing a file as a dependency

When working in a project, it can be error prone to try and remember the exact name and path of a javascript module you want to import in some other module.

M-x requirejs-import-file fixes this problem by giving you a mini-buffer prompt from which you can browse your file-system for the said module. It will then insert it in the dependencies list of your current module definition and insert a CamelCased version of it's name in the function definition.

It goes the extra mile by doing some extra processing to the file-name you imported.

• Trims the .js extension and transforms dash-based-names to CamelCased in function def.
• Prepends text! in the dependency to make use of the text plugin of requirejs if the file you import is a template.
• Adds View to the variable name if the file you import is within a views folder.
• Adds Template to the variable name if the file you import is within a templates folder.

Here are a couple examples. Note: I use Backbone.js lately so most of these are Backbone related in some way, but not necessarely exclusive to it.

• Importing .../javascripts/models/item.js

Will result in adding 'models/item' in the dependencies list and Item in the function definition.

• Importing .../javascripts/views/item.js

Will result in adding 'views/item' in the dependencies list and ItemView in the function definition.

• Importing .../javascripts/collections/items/sold-items.js

Will result in adding 'collections/items/sold-items' in the dependencies list and SoldItems in the function definition.

• Importing .../../templates/item.html

Will result in adding 'text!templates/item.html' in the dependencies list and ItemTemplate in the function definition.

• Importing any file not within one of the {models, views, collections, templates} sub-folders.

Will result in adding 'file-name' in the dependencies list and FileName in the function definition. Thus assuming you have correctly setup your require.config({ paths: {...} });.

Adding a known module as a dependency

When you import a file as a dependency, it will save its ('dependency-name', DependencyDeclaration) pair in a temporary associative list for the life-time of your Emacs session. You can then access these quickly by using M-x requirejs-import-add and pick the one you need. It will then be inserted in your current module definition.

Some defaults are already loaded in this temporary associative list for quick access:

'jquery'     -> $
'underscore' -> _
'backbone'   -> Backbone

Creating an empty module

This functionnality is only there to circumvent the need to depend on a snippet system to create the boilerplate structure of the module. Notice that if the previous features don't find a proper AMD structure within the current file, it will use this feature to create one and then insert the desired imports.

Explicity, it generates: ``` define ( [],
function ( ) {

}

); ```

Keybindings

• C-c rf : require-import-file
• C-c rc : require-create
• C-c ra : require-import-add

Dependencies

No dependencies, but it will use ido to auto-complete prompts if it is present.
