Python

Python debugger allows debugging Python scripts on VMS.

Features

  1. Running python script on VMS side
  2. Breakpoints
  3. Displaying local variables in each accessible frame
  4. Multithreading
  5. Post-mortem information about unhandled exceptions.
  6. Changing variable value
  7. Jump to cursor inside a frame

How to run

  1. Setup SSH settings
  2. Setup project settings: because Python scripts do not need compilation, not all settings are required. Only those which are required for synchronization. So "outdir", "root" and include/exclude masks do matter. Outdir is used only for holding debugger scripts. Masks used only for synchronization, no difference between is it a source, headers e.t.c.
  3. Setup launch: open launch.json, then "Add configuration" => "VMS IDE: Launch Python script".
