Node.js for Windows and Macs — forward slash, backslash rectification

由 孤街醉人 提交于 2020-01-13 11:43:36
问题 Is there a method to rectify the discrepancy in node.js from Windows to Linux and Mac concerning the backslash versus forward slash? Windows requires backslashes when calling locations in git bash , while Mac/Linux requires forward slashes. I'm working on a project with both Mac and Windows users so I can't change all the forward slashes to backslashes in the code because when Mac users pull, coffee wont be able to properly run for them and vice versa. Is there a solution to this? 回答1: Make

Unhandled rejection error Bluebird

由 南笙酒味 提交于 2020-01-13 10:29:21
问题 I have the following code. And it works as expected without throwing a unhandled rejection error. p = new Promise (fulfill, reject) -> reject new Error 'some error' p.catch (error) -> console.log error Now, the second code example does throw an unhandled rejection error. Can someone explain to me why this is happening when im clearly handling the error. p = new Promise (fulfill, reject) -> reject new Error 'some error' p.then -> console.log 'ok' p.catch (error) -> console.log error Btw. I'm

Can't require local CoffeeScript modules

问题 I'm running Node.js 0.10.21. I tried both CoffeeScript 1.6.3 and master both with and without require('coffee-script/extensions') . Compiling the two files to JavaScript and running them directly in Node works just fine of course. # ./folder/a.coffee require('../b').test() # ./b.coffee exports.test = -> console.log 'yay' # $ coffee folder/a.coffee # # Error: Cannot find module '../b' # at Function.Module._resolveFilename (module.js:338:15) # at Function.Module._load (module.js:280:25) # at

Why does CoffeeScript wrap class definitions in a closure?

由 别说谁变了你拦得住时间么 提交于 2020-01-11 08:20:22
问题 In CoffeeScript, this: class Foo method: (x) -> x+1 Compiles to: // Generated By CoffeeScript Foo = (function() { function Foo() {} Foo.prototype.method = function(x) { return x+1; } return Foo; })() Which seems a bit excessive. The following should be functionally identical : // Generated by Dave function Foo() {} Foo.prototype.method = function(x) { return x+1; } What is the motivation for the extra "closure" wrapper? This is not merely an idle question of styling; it has implication to

Coffeescript wrapping files in a function

由 情到浓时终转凉″ 提交于 2020-01-10 10:39:09
问题 The coffeescript compiler is, for some reason, wrapping all of my .coffee files in a function when they are compiled. For example, if I have test.coffee: class TestClass constructor: (@value) -> printValue: () -> alert(@value) printAValue = () -> test = new TestClass() test.printValue() then I get test.js: (function() { var TestClass, printAValue; TestClass = (function() { function TestClass(value) { this.value = value; } TestClass.prototype.printValue = function() { return alert(this.value);

how to debug coffeescript in node.js with webstorm 6 source maps

由 喜你入骨 提交于 2020-01-10 10:16:04
问题 I've set up the coffeescript file watcher like in this video http://www.youtube.com/watch?v=Sl1Uk3zT5Fg Which seems to work fine for an html project debugging with google chrome. However, when I start debugging and set a breakpoint in the coffeescript file in a node.js project, it doesn't hit the breakpoint. Setting a breakpoint in the generated js file does however get hit. What do I need to do for the debugger to use the generated source maps and step through the coffeescript with node.js
