LLDB --run-mode=this-thread or GDB scheduler-locking on

[koutheir]

I'm debugging a multi-threaded program, and I'd like to control what threads make progress. In GDB, I'd set scheduler-locking on and then step the thread I need to investigate. In LLDB, I'd use the --run-mode=this-thread parameter of the si command. Is there a way I can do this through the UI of this extension?

Not via the UI. For step-in (F11) CodeLLDB uses the equivalent of --run-mode=while-stepping.
You can execute si --run-mode=this-thread from the debug console.

When I do that, the single step happens, but the UI then switches back to another thread, and not the one I'm stepping through. It keeps switching between threads like that. Is there a way to keep the thread I'm stepping through the selected/active thread in the UI?
