dirge-agent 0.13.0

"""
Test program for DAP integration tests.

Exercises a broad range of DAP features:
  - Launch with stopOnEntry
  - Line breakpoints (plain + conditional)
  - Continue
  - Step over (next)
  - Step in (stepIn)
  - Step out (stepOut)
  - Stack trace inspection
  - Variable inspection (locals, globals, complex types)
  - Expression evaluation
  - Thread listing
  - Stdout output capture

Intended to be run with debugpy or any Python-capable DAP adapter.
