Python
Python debugger allows debugging Python scripts on VMS.
Features
- Running python script on VMS side
- Breakpoints
- Displaying local variables in each accessible frame
- Multithreading
- Post-mortem information about unhandled exceptions.
- Changing variable value
- Jump to cursor inside a frame
How to run
- Setup SSH settings
- 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 own scripts (tracer and server). Masks used only for synchronization. There is no difference between whether it is a source, headers e.t.c.
- Setup launch: open launch.json, then "Add configuration" => "VMS IDE: Launch Python script".
| Property | Meaning |
|---|---|
| "type": "vms python debugger" | do not change |
| "request": "launch" | do not change |
| "name": "Launch Python Script" | write an unique name |
| "script": "${file}" | file name or "${file}" for currently opened file under cursor |
| "port": "55005-55025" | range of local ports on VMS, used for communication between tracer and server scripts |
| "arguments": "" | script arguments |
Select this launch configuration and press F5. Script always stops at the first line.
Debugging
Not all files are traced by default. Only local files. To enable tracing non-local files do edit extension setting Vms_python_debug: Roots and add pairs of values
VMS_PATH_in_UNIX_FORMAT : LOCAL_PATH_as_C_STRING
The file will be traced if:
- It is local
- It has a break point
- It is in VMS folder, selected by command 'y path' where path is VMS path in UNIX format (command 'y' with empty path clears current path)
- Debugger is in developer mode, switched by command 'm 1' (to switch back use 'm 0') or defined in settings.
