Unexpected ANSI escape codes on VS Code integrated terminal

Question

My visual studio code integrated terminal is showing some escaped ANSI codes on every command line:

\x1b7\x1b[38\x3b2\x3b122\x3b122\x3b122m ❮ \x1b[0m\x1b[38\x3b2\x3b159\x3b211\x3b86m

Those are the current settings related to the terminal:

"terminal.integrated.fontSize": 12,
"terminal.integrated.cursorStyle": "line",
"terminal.integrated.defaultProfile.windows": "PowerShell",
"terminal.integrated.enableImages": true,
"terminal.integrated.persistentSessionReviveProcess": "never"

I also have Oh My Posh 19.24.2 configured through PowerShell user profile:

oh-my-posh init pwsh --config "C:\Users\sergi\AppData\Local\Programs\oh-my-posh\themes\slimfat.omp.json" | Invoke-Expression

How to fix?

Answer 1

As BDENsys said in their answer, using oh-my-posh init pwsh | Invoke-Expression works. But it is a temporary solution. The ANSI escape overflows still occur in a new instance of VSCode

Adding oh-my-posh init pwsh | Invoke-Expression on $PROFILE wasn't working for me. I resolved it by going to my VS Code settings terminal.integrated.profiles.windows and updating PowerShell settings like this.

"PowerShell": {
            "source": "PowerShell",
            "icon": "terminal-powershell",
            "args": [
                "-NoExit",
                "-Command",
                "oh-my-posh init pwsh | Invoke-Expression"
            ]
        }

Apparently the "args" allows you to run a command whenever Pwsh instance is created.

You need to disable shell integrations in vscode. If you want to enable shell integrations, you can do from your oh-my-posh config using "shell_integration": true.
