[英]Uncaught ReferenceError when trying to change js function into coffeescript
This is the error: 这是错误:
Uncaught ReferenceError: er is not defined
This is the code .. 这是代码..
{CompositeDisposable} = require 'atom'
lib = require 'lib'
module.exports =
subscriptions: null
activate: ->
@subscriptions = new CompositeDisposable
@subscriptions.add atom.commands.add 'atom-workspace',
'my-package:convert': => @convert()
deactivate: ->
@subscriptions.dispose()
convert: ->
console.log 'Convert text!'
if editor = atom.workspace.getActiveTextEditor()
console.log editor.getText()
lib.process(editor.getText() (er files)) ->
console.log 'All files ..'
listFiles(files)
listFiles: (files) ->
for fileName in Object.keys(files)
first = files[fileName].first
second = files[fileName].second
third = files[fileName].third
console.log 'Done'
This is the javascript
I'm trying to change to coffeescript
inside convert()
.. 这是我要在convert()
更改为coffeescript
的javascript
。
lib.process(text, function (er, files) {
console.log('All files ..');
listFiles(files);
});
The line 线
lib.process(editor.getText() (er files)) ->
is not correct, since it's missing the commas needed to separate the parameters. 是不正确的,因为它缺少分隔参数所需的逗号。
When trying to transpile the line you wrote to JS it would look like this: 尝试转译您写给JS的行时,它看起来像这样:
lib.process(editor.getText()(er(files)))(function() {});
When trying to migrate JS to coffee, it's sometimes a good idea to start with http://js2.coffee/ and start from there. 尝试将JS迁移到咖啡时,从http://js2.coffee/开始并从那里开始有时是个好主意。 Always look at the transpiled JS result in order to check if everything will work as expected 始终查看转译的JS结果,以检查是否一切都能按预期工作
