HI. Please try https://www.nuget.org/packages/Terminal.Gui/2.0.0-develop.4743

Try dotnet run -p ./Examples/UICatalog

If that fails, please try:

Run dotnet run -p ./Examples/UICatalog -d dotnet

Thanks

Hi.

dotnet run -p ./Examples/UICatalog -d dotnet - works fine!

dotnet run -p ./Examples/UICatalog - does not work

[tig]

Thanks for testing. If you're willing, i'd appreciate you trying one more thing:

1. Checkout the v2_4471-Continuous branch and pull it.
2. Run dotnet run -p ./Examples/UICatalog -d ansi

Try dotnet run -p ./Examples/UICatalog -d unix again too.

I don't have a mac so I can't test this directly. Regardless, we'll work on getting this fixed asap (assuming -d unix still doesn't work).

Note that branch is not really ready for prime time.

[beddead]

I don't see the v2_4471-Continuous branch

[tig]

Ooops:

#4472

[beddead]

dotnet run -p ./Examples/UICatalog -d ansi - works correctly
dotnet run -p ./Examples/UICatalog -d unix - doesn't work

[tig]

That is very interesting thank you very much for giving it a go.

The new ansi driver uses many of the same API calls that the unix Driver uses and in fact they share a lot of code now. But not completely.

@BDisp since you wrote the Unix Driver, would you please look at this?

[BDisp]

I only can test in the macOS Sequoia 15.4.1 which doesn't reproduce any error. I don't have macOS Tahoe 26, sorry. I'll try to download it but it will take a few days.

[beddead]

I have some update. It shows main screen with unix driver inside VS Code integrated terminal when I start Debug

[beddead]

@BDisp, on your screenshot, the label shows "unix" rather than "unix driver". Why is that?

@BDisp, on your screenshot, the label shows "unix" rather than "unix driver". Why is that?

Because I only used the v2_develop branch and you used the new PR #4472 branch. Please modify the launch to use external terminal and see if it's also working. Which terminal do you use? If it successfully work it's maybe VSCode installed some necessary component.
