Code of Conduct

• [X] I agree to follow this project's Code of Conduct

What happened?

At random times, rendering one or more elements of the prompt results in errors of the following format:

"oh-my-posh fatal error rendering [segment] segment:runtime error: invalid memory address or nil pointer dereference"

The affected segment displays the text "error" when this event occurs. The affected segment can be something as trivial as the operating system logo or the last execution timer.

Of note, I also use the same theme inside several WSL instances and on a few Linux servers. In Windows/Powershell is the only time I see this behavior.

[lnu]

I also noticed this a few days ago. Happened to me on windows, never on MacOS.

[JanDeDobbeleer]

Might be related to updating some dependencies, will check (nil pointers are identifiable luckily).

[JanDeDobbeleer]

@lnu @cyveris looking at that I have no idea what's causing this, it's a good idea anyways to add the stack trace to the error so we have a clue of what's going on when it happens again.

[amaechler]

Just noticed this for the first time, with the following stack trace:

it's an issue with the latest changes. @JanDeDobbeleer has been notified. https://github.com/JanDeDobbeleer/oh-my-posh/commit/04f841d1b323f58e8e1b7c33f96eae26ea00558b.

For the time being rollback to a previous version, the fix is on its way.

[JanDeDobbeleer]

The fix is building

[JanDeDobbeleer]

Status update: GitHub Releases is experiencing issues, I unlisted this release and the Powershell module so stay tuned.

[JanDeDobbeleer]

Status update: fix is available

[Kyllingene]

I have the same issue, just downloaded oh-my-posh today; it happens on all themes I've tried (default, the bubbles family, atomic, etc.). I'm using it in Nu on Windows Terminal.

[JanDeDobbeleer]

@Kyllingene can you share your config ?

[Kyllingene]

My Nu config is just this: prompt = "(oh-my-posh --config C:/Users/josia/scoop/apps/oh-my-posh/current/themes/<theme>.json | str collect)"

[JanDeDobbeleer]

@Kyllingene do you also have a stacktrace? Because it should print it (provided oh-my-posh is up to date).
