coffeescript

问题 If I do repl = require 'repl' repl.start {useGlobal: true} It starts a Node repl. How do I start a CoffeeScript repl instead? Thanks 回答1: Nesh is a project to try and make this a bit easier and extensible: http://danielgtaylor.github.com/nesh/ It provides a way to embed a REPL with support for multiple languages like CoffeeScript as well as providing an asyncronous plugin architecture, support to execute code in the context of the REPL on startup, etc. For example: nesh = require 'nesh' nesh

问题 In my Rails 3.2 app (Ruby 1.9) I get following error when using path helpers in Coffeescript. undefined local variable or method `new_user_session_path' In my partial _usermenu.html.haml that works fine: = link_to t('user.login'), new_user_session_path In my app/assets/javascripts/metamenu.js.coffee.erb that throws above error: $.get("<%= new_user_session_path %>") Isn't it possible to use x_path and x_url helpers in coffeescript erb's? 回答1: This is because you are not within the view context
