我在Visual Studio 2015 RC中使用新的Apache Cordova空白模板.我注意到项目中的taco.json文件.除了定义您正在使用的Apache Cordova版本之外,它还可以用于任何其他目的吗？

是否像bower一样定义其他框架,如角度或引导程序？

我有以下代码:

app.js:

var passport = require('passport')
  , FacebookStrategy = require('passport-facebook').Strategy
  , ...
passport.serializeUser(function(user, done) {
  console.log('serializing user')
  done(null, user);
})
passport.deserializeUser(function(obj, done) {
  console.log('deserializeUser')
  done(null, obj)
})
passport.use(new FacebookStrategy({
    clientID: FBAPP.id,
    clientSecret: FBAPP.secret,
    callbackURL: 
      "http://www.mylocal.com:3000/auth/facebook/callback"
  },
  function(accessToken, refreshToken, profile, done) {
    // asynchronous verification, for effect...
    process.nextTick(function () {
      return done(null, profile)
    })
  }
))
app.get('/auth/facebook', passport.authenticate('facebook', 
  { scope: ['email, user_likes, user_photos, publish_actions'] }))
app.get('/auth/facebook/callback', 
passport.authenticate('facebook', { 
  successRedirect: '/loginsuccess', failureRedirect : '/loginfail' }))
app.get('loginsuccess', function(req, res) {
   console.log('Login success')
  res.send(200, …

在我为Visual Studio 2015编写的扩展中,我希望更改选项卡大小和缩进大小,因为在工作中我们有不同的设置,就像我正在开发开源项目(公司历史记录在我们的C期间).我在命令类中编写了以下代码:

private const string CollectionPath = @"Text Editor\CSharp";
private void MenuItemCallback(object sender, EventArgs e)
{
  var settingsManager = new ShellSettingsManager(ServiceProvider);
  var settingsStore = settingsManager.GetWritableSettingsStore(SettingsScope.UserSettings);
  var tabSize = settingsStore.GetInt32(CollectionPath, "Tab Size", -1);
  var indentSize = settingsStore.GetInt32(CollectionPath, "Indent Size", -1);
  if (tabSize != -1 && indentSize != -1)
  {
    settingsStore.SetInt32(CollectionPath, "Tab Size", 2);
    settingsStore.SetInt32(CollectionPath, "Indent Size", 2);
  }
}

在实验配置单元中进行测试时,当您单步执行该方法时,它会更改它,但是当您打开"选项"对话框时,它将保持原始值.再次调试时,值保持原始值.

我忘记了什么或做错了什么？

我得到以下内容:

data Pair a =
  Pair a a

并希望将Eq类型类实例化为它.

instance Eq (Pair a) where
  (==) (Pair x x') = x == x'

我收到错误:

无法匹配预期类型对a - > Bool'与实际类型Bool'

我写错了什么？

我有以下代码,测试失败:

open Xunit
open FsUnit.Xunit

let rec openOrSenior xs = 
    match xs with
    | head :: tail when fst head >= 55 && snd head >= 7 -> "Senior" :: openOrSenior tail
    | head :: tail -> "Open" :: openOrSenior tail
    | [] -> []

[<Fact>]
let ``empty input gives empty result``() =
    openOrSenior [] |> should equal List.empty

测试失败,出现以下匹配错误

FsUnit.Xunit + MatchException:抛出了类型'FsUnit.Xunit + MatchException'的异常.预期:等于[]
实际:是[]

我有以下代码:

type ActorState int

const (
    Unverified ActorState = 1 + iota
    Verified
    Banned
)

我希望在我的实施中这样做.

i := 1
a : ActorState 
a = ActorState(i)

但是我得到了错误Cannot convert expression of type int, error to type ActorState.

我怎么转换呢？
