## Install VSCode Extension
|
|
|
|
To debug a pocketpy program, you need to install our VSCode extension first:
|
|
|
|
https://marketplace.visualstudio.com/items?itemName=pocketpy.pocketpy
|
|
|
|
!!!
|
|
The VSCode extension requires pocketpy version >= `2.1.1`
|
|
!!!
|
|
|
|
## Create a `launch.json` file
|
|
|
|
Navigate to the Debug view in VSCode, and click on "create a launch.json file" link.
|
|
In the dropdown menu, select "pocketpy".
|
|
|
|
|
|
|
|
Then a default `launch.json` file will be created in the `.vscode` folder
|
|
with a sample pocketpy debug configuration.
|
|
|
|
## How does it work?
|
|
|
|
pocketpy provides a C-API `py_debugger_waitforattach`,
|
|
which starts a debug server and waits for the VSCode extension to attach.
|
|
When the debugger is attached, the program will continue to run.
|
|
|
|
+ If you are using pocketpy's standalone executable `main.exe`, you can pass `--debug` flag to it. This will automatically call `py_debugger_waitforattach("127.0.0.1", 6110)` before running your program.
|
|
+ If you are embedding pocketpy as a library, you need to call `py_debugger_waitforattach` manually in your C/C++ code.
|
|
|
|
## Configuration
|
|
|
|
+ `type`: must be `pocketpy`
|
|
+ `request`: can be `attach` or `launch`
|
|
+ `name`: the name of this configuration
|
|
+ `port`: the port number of the debug server, must match the one in `py_debugger_waitforattach`
|
|
+ `host`: the host of the debug server, must match the one in `py_debugger_waitforattach`
|
|
+ `sourceFolder`: the root folder of your python source code, default to `${workspaceFolder}`. However,
|
|
sometimes you may run your program from a subfolder, in this case you need to set `sourceFolder` to the correct path. If this is not set correctly, breakpoints will not be hit.
|
|
+ `program`: (for launch mode only) the path to the executable file which calls `py_debugger_waitforattach`, e.g. the pocketpy standalone executable `main.exe`.
|
|
+ `args`: (for launch mode only) the arguments to pass to the executable file, e.g. `--debug` and the script path if you are using `main.exe`.
|
|
+ `cwd`: (for launch mode only) the working directory to launch the executable file, default to `${workspaceFolder}`.
|
|
|
|
### For attach mode
|
|
|
|
In this mode, you need to start your pocketpy program manually which must call `py_debugger_waitforattach` first.
|
|
After the program starts, you can let VSCode attach to the debug server.
|
|
|
|
```json
|
|
{
|
|
"type": "pocketpy",
|
|
"request": "attach",
|
|
"name": "Attach to pocketpy program",
|
|
"port": 6110,
|
|
"host": "localhost",
|
|
"sourceFolder": "${workspaceFolder}"
|
|
}
|
|
```
|
|
|
|
### For launch mode
|
|
|
|
In this mode, VSCode will start your program with the specified `program`, `args` and `cwd`.
|
|
After the program starts, VSCode attempts to attach to the debug server automatically.
|
|
|
|
```json
|
|
{
|
|
"type": "pocketpy",
|
|
"request": "launch",
|
|
"name": "Launch pocketpy program",
|
|
"port": 6110,
|
|
"host": "localhost",
|
|
"sourceFolder": "${workspaceFolder}",
|
|
"program": "${workspaceFolder}/pocketpy/main.exe",
|
|
"args": [
|
|
"--debug"
|
|
],
|
|
"cwd": "${workspaceFolder}"
|
|
}
|
|
```
