Konsole.Writer.MoveBufferArea throws System.PlatformNotSupportedException on Nix Platforms #80

Closed Evelios closed 3 years ago

Evelios commented 3 years ago

I'm running into the exception System.PlatformNotSupportedException when running on linux. Through some sleuthing I discovered your stack overflow case Is there any way to set the left and right margin of a console using Terminal sequences? the same way we can currently set Top and Bottom?. From your issue it is not clear if you found an acceptable answer to your question. This also could be a duplicate of issue #30. I am compiling and running using .Net Core 3.1. If it is relevant am running the mate terminal and also need to support xterm for my users.

Relevant stack trace.

Unhandled exception. System.PlatformNotSupportedException: Operation is not supported on this platform.

Hi @Evelios

I feel your pain, unfortunately there's some work that has to be done before this can be fixed. This is essentially a duplicate of #30

i.e. the goal is to do important API refactors in version 7, new Input features in version 8, (keyboard handlers, maybe mouse support), and cross platform support in version 9.

Let me know your thoughts?

txs,

Alan

btw you can work around some problems with scrolling by changing how your code writes with Konsole, if you want to keep using Konsole. Set the window to Clip instead of scroll. So you can use Konsole to open a small window at location X, Y and have a progress bar in the window, print some status updates etc, use printAt to print at specific locations, benefit from being threadsafe etc.
