coffeescript

问题 I'm wondering whether it's possible to compile Haxe to Coffeescript - are there any tools that are available for this? I find Coffeescript's syntax to be much more concise than that of Javascript, so I'd like to find a Coffeescript target for Haxe (if it exists.) 回答1: Haxe already has a Javascript target, and there is already a Javascript-to-Coffeescript that is available ( http://js2coffee.org/ ), so it should be possible, as long as js2coffee does not make any errors in compiling Javascript

问题 I have the following javascript: Function.prototype.debounce = function (threshold, execAsap) { var func = this, timeout; return function debounced () { //body } }; How can I return a named function like this in coffeescript? 回答1: You can't name functions in Coffeescript. The reason is given in the FAQ -- grep for "Is there any way to name functions, for reflection and recursion?" If you really need to embed a name, you could use backticks to embed raw Javascript. 来源： https://stackoverflow

问题 I'm having a Angular-CLI application and I try to bring in a third party dependency in, which is written in Coffee Script . This is what I do in my component: const CoffeeWidget = require('coffee-loader!CoffeeWidget'); I thought using a coffee loader would work. But not really. Now I'm able to read the index.coffee , but in my index.coffee I require other coffee files. Like: Cup = require '../tools/cup.coffee' But it has problems to ready the cup.coffee and says: You may need an appropriate

问题 I have the following Backbone router definition in CoffeeScript: // appointments_router.js.coffee define ["app", "appointment"], (App) -> class Snip.Routers.AppointmentsRouter extends Backbone.Router initialize: (options) -> @appointments = new Snip.Collections.AppointmentsCollection() @appointments.reset options.appointments Here is the "appointment" module on which it depends: // appointment.js.coffee define ["app", "relational"], (App) -> class Snip.Models.Appointment extends Backbone

问题 Say I have a Coffeescript class: class Foo MyMethodsBar: () => "bar" MyMethodsBaz: () => "baz" Is there any way to encapsulate methods like this (not working): class Foo MyMethods: bar: () => "bar" baz: () => "baz" So I can call: f = new Foo() f.MyMethods.bar() The problem is that this (or @ ) is not the instance when I do this like a regular method. I'm trying to do this for cleaner mixins/concerns. Thanks, Erik 回答1: Nope, this is not possible, unless you create MyMethods inside the

问题 What I've been attempting to do is create one scripts task that takes all .coffee and .js files and does what's needed for each: Coffee files should be run through coffee(), coffeelint() and coffeelint.reporter() JS files should be run through jshint() All files should then be run through concat(), uglify() and ultimately setting a destination as a final build file. The reason I have some .coffee and some .js is because I'm using Bower components that have JS files, even though I'd like to

问题 On server.coffee I have: User = mongoose.model 'User', s.UserSchema addEntryToCustomer = require './lib/addEntryToCustomer' and on addEntryToCustomer.coffee I have: module.exports = (phone,res,req) -> User.find {account_id: phone.account_id }, (err, user) -> And I get this error: 2011-11-14T19:51:44+00:00 app[web.1]: ReferenceError: User is not defined 回答1: In node.js, modules run in their own context. That means the User variable doesn't exist in addEntryToCustomer.coffee . You can either

问题 When inserting a record I need to be able to run one or more queries on the server which will reject the insert if it finds any results. Will Firebase allow me to do this? It can't be specified on the client or it could be easily subverted. For a more concrete example, I have a Meteor app that currently let's me do rate limiting on votes with some pretty simple code. I would like to implement this in Firebase. (Please forgive the CoffeeScript) @VoteFrequency = votesPer: (sinceDelta, sinceUnit
