Debugger

Stop your program where it matters and look around. Set a breakpoint, step through line by line, and inspect variables and the call stack while everything is paused.

What you can do

• Set breakpoints by clicking the editor gutter or pressing F9, turn them on and off, and have them remembered per project
• Control the run: Continue (F5), Pause (F6), Step Over (F10), Step Into (F11), Step Out (Shift+F11), Restart, Stop (Shift+F5)
• Inspect the call stack, expand variables as you need them, and add watch expressions
• Read your program's output and evaluate expressions in the paused frame from the Debug Console
• Keep launch configurations in .punica/launch.json (a VS Code-compatible subset, with ${workspaceFolder} and ${file}), or let the active file be configured for you

Language support

Language	Adapter	Status
Python	debugpy (pip install debugpy)	✅
Go	delve	Planned
Node.js	js-debug	Planned

Requirements

• The desktop app — debugging spawns local adapter processes, so it is not available in the browser
• For Python, an interpreter with debugpy installed. The sidebar shows you the install command when it is missing

Example .punica/launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Python: Current File",
      "type": "python",
      "request": "launch",
      "program": "${file}",
      "console": "internalConsole",
      "justMyCode": true
    }
  ]
}

Getting started

Open a Python file, click the gutter next to a line to set a breakpoint, and press F5.
