René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Add a way to see if a remote debugger has attached","articleBody":"### Summary of the new feature / enhancement\r\n\r\nAs a user who may want to attach to an otherwise unattended process to debug it, I want to be able to pause execution in said unattended process until I'm able to attach to it.\r\n\r\n### Proposed technical implementation details (optional)\r\n\r\nA common pattern in C# for this would be something like\r\n\r\n```cs\r\nwhile (!Debugger.IsAttached) Thread.Sleep(200);\r\nRestOfCodeHere(); // breakpoint on this line\r\n```\r\n\r\nCurrently in PowerShell there's no supported way to tell if a debugger is attached to the current runspace. A minimal way to enable this scenario would be a property on `Runspace`:\r\n\r\n```diff\r\npublic partial abstract class Runspace\r\n{\r\n+   public bool IsRemoteDebuggerAttached { get; }\r\n}\r\n```\r\n\r\nThis would allow the user to write the code\r\n\r\n```powershell\r\nwhile (-not $Host.Runspace.IsRemoteDebuggerAttached) { Start-Sleep -Milliseconds 200 }\r\nInvoke-RestOfCodeHere # breakpoint on this line, or just make it `Wait-Debugger`\r\n```\r\n\r\nIf there is sufficient demand for it, a command or method to wait for attach can also be considered, but to start off the proposal I'd recommend this as an MVP.\r\n\r\nOne question that I would suggest be answered in the WG decision is: \"What should a remote runspace do for this parameter? Throw? Or always return false?\"\r\n","author":{"url":"https://github.com/SeeminglyScience","@type":"Person","name":"SeeminglyScience"},"datePublished":"2024-03-29T15:55:24.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/21392/PowerShell/issues/21392"}
