how to make the debugger work consistently?

[Rom265]

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

I can't get the debugger to work. Sometimes it will, sometimes it won't. The code just runs ignoring break points. I tried to follow the instructions in https://devblogs.microsoft.com/scripting/debugging-powershell-script-in-visual-studio-code-part-1/#comments but they aren't even right. They no longer describe the user interface. So, I don't know what to do. I got the "Powershell Launch Current File" into the drop down on the RUN AND DEBUG window. It seems like that worked once, but then I stopped the run part way through the script and the terminal hung on the DBG prompt. So, I closed that terminal. It popped up a message saying that it needed to be running; so, I started it again. But now, no breaking. Did I do it right, but this Powershell extension just really is broken or what?

Can you try PowerShell 7? The PowerShell 5.1 support is best effort, and debugging is where it gets seriously janky (it doesn't have the debugger APIs that we use to support proper debugging like we do with PowerShell 7).

Thanks for replying, but no sadly it looks like I'll have to give up on VS Code again and go back to Powershell ISE as my only real choice for using Powershell.

I have the same problem. Until PowerShell cmdlets for Azure etc support functionality that was available I am still expected to maintain code for customers in older versions of PowerShell. After moving the team to VSCODE its a massive step backwards as it took me months to get people off ISE. The latest is "Exception encountered starting EditorServices. Exception logged in D:\a_work\1\s\src\PowerShellEditorServices.Hosting\Commands\StartEditorServicesCommand.cs on line 238 in EndProcessing:"

Completely dead in the water on this

This looks like its related to some update in the ps add on

If there's an error, restarting the term usually resolves that.

Without logs, there's a bunch of different things that could have happened, we can't know what. It's not necessarily the debugger.

Re-Attach Debugger

if the debugger isn't attaching when you're running

Import-Module x -Force
DoStuff

• Then in DoStuff place wait-debugger
• save, run it
• now you can delete wait-debugger
• regular breakpoints are now working

---

update

When addons update, sometimes they require a reload. Until you reload, it definitely can break things. But that's not pwsh specific.

I figured it out. The problem stems from the fact that I have used Powershell a lot. This program is NOTHING LIKE Powershell ISE which I am used to. Actually, the problem is that this program is not made for Powershell and that will always be a problem. In some ways it will always be harder to use. Certainly harder to get started with. So, I expected that when I run a command from the terminal prompt, it will run. It does and that fools you because, to engage the debugger, you can ONLY USE F5 (or the icon). This means that you must create a temporary file somewhere, open it in VS Code, write the command line you need and then hit F5 there. Voila, it stops at the break point. Yes, this is very kludgy, one of the several ways Powershell presumably does not match the languages VS Code was created for.

If you put a Wait-Debugger in the command / script-block you're running, that should start up and attach the VS Code debugger too (if it doesn't, let me know, I worked real hard to wire that up)! You should also check out the "Interactive Session" supplied default debug configuration.

Also,

You really hit the nail on the head about how difficult the development and maintenance of this extension is 😅

We also have some work-in-progress to sync PowerShell breakpoints set via Set-PSBreakpoint etc. with the VS Code debugger: #4065 no ETA though.
