【问题描述】：

我想按以下格式列出可用的 ios 模拟器（iOS 版本应取自 JSON 密钥）

{
  "name": "iPhone 5s (11.4)",
  "udid": "FB6B3F7F-E6CD-4F64-8EC4-6C07C86A25C8"
}
{
  "name": "iPhone 6 Plus (11.4)",
  "udid": "768AE0B3-F77A-4DF4-8198-74CB2D598D19"
}
...
{
  "name": "iPad Air (11.4)",
  "udid": "396C0E3A-7DFD-41BD-9E05-28A27E6BB4AB"
}
{
  "name": "iPad Air 2 (11.4)",
  "udid": "1AD4AC1A-B45B-4869-9778-B5572D4CE031"
}
...
{
  "name": "iPhone 8 (13.2)",
  "udid": "71E02A7B-BCBB-45D8-8638-E5381B420406"
}
{
  "name": "iPhone 8 Plus (13.2)",
  "udid": "D3333C55-2D0A-4999-B6D2-450C637C9248"
}
...
{
  "name": "iPad (7th generation) (13.2)",
  "udid": "0543121E-86DC-4BC9-933F-60AA31D219CD"
}
{
  "name": "iPad Pro (11-inch) (13.2)",
  "udid": "1979F272-E938-45AA-9717-A5228AF6EBF1"
}
...

我试过这样的东西

xcrun simctl list --json devices available | jq '.devices | with_entries(select(.key|contains("com.apple.CoreSimulator.SimRuntime.iOS")))'

但我无法实现其余的 jq 操作以达到预期的格式。

xcrun simctl list --json devices available 的输出如下

{
  "devices" : {
    "com.apple.CoreSimulator.SimRuntime.iOS-11-4" : [

如何按预期格式列出可用的 ios 模拟器？

【问题讨论】：

xcrun 调用的 json 是什么样的？
@kumara：您需要提供xcrun simctl list --json devices available 的输出，然后才能有人回答您。该命令的输出在线示例并不多，大概是因为那些觉得需要运行它的人可以这样做。
@SimonShine @JeffMercado 我添加了xcrun simctl list --json devices available的输出
感谢@Dmitry 我尝试使用 jtc 这种方法很酷。但是设备名称中没有添加iOS版本。版本取自密钥。我需要来自“com.apple.CoreSimulator.SimRuntime.iOS-11-4”的东西：[{“state”：“Shutdown”，“isAvailable”：true，“name”：“iPhone 5s ", "udid" : "FB6B3F7F-E6CD-4F64-8EC4-6C07C86A25C8" },... to { "name": "iPhone 5s (11.4)", "udid": "FB6B3F7F- E6CD-4F64-8EC4-6C07C86A25C8" },...
@kumara，这很容易——只需将版本捕获（通过正则表达式）到正则表达式组（它们也是命名空间）中，然后在模板插值期间使用它，如下所示：xcrun ... | jtc -x'<^com\.apple\.CoreSimulator\.SimRuntime\.iOS-(\d+)-(\d+)>L:[0][-1]<name>l:<n>v[-1][udid]' -T'{"name":"{n} ({$1}.{$2})", "udid":"{}" }'

标签： ios ios-simulator jq xcrun simctl

【解决方案1】：

您尝试获取的版本信息是设备密钥的一部分。因此，您需要将其提取出来并根据需要构建您的结果格式。您可以使用 contains 结合子字符串来执行提取，但在这里使用 capture/1 可以简化过程。

这是您可以做到的一种方法：

$ xcrun ... | jq '.devices | to_entries[]
  | (.key | capture("com\\.apple\\.CoreSimulator\\.SimRuntime\\.iOS-(?<version>.+)")) as {$version}
  | .value[] | {name: "\(.name) (\($version|sub("-"; ".")))", udid}'

【讨论】：

... as {$version} 中的花括号有什么作用？
@jeff 不错！这很好用。我非常感谢您的时间。
@SimonShine 在这里使用捕获的结果返回一个具有“版本”属性的对象，该对象具有从键中捕获的组。我们正在解构该对象以将该版本属性直接保存到 $version 变量中。
哦！！！惊人的。谢谢，@JeffMercado。我是否正确假设解构仅在 as 和 ??/ 之后在语法上可用，还是在其他地方可用？
@SimonShine 好吧，据我所知，as 和 ?// 是唯一的地方。有人可能会争辩说，它也可以用于函数参数，但我认为目前还没有实现。
