pokemon

Pokemon is a library to link to your C++ program to debug Lua code using QtCreator.

Usage

Configure your environment

Set the environment variable QTC_QMLDEBUGGER_FILEEXTENSIONS to the file extensions for QML/JS and Lua:

bash$ export QTC_QMLDEBUGGER_FILEEXTENSIONS=".qml;.js;.lua"

Restart QtCreator from the updated environment.

Configure your project in QtCreator

Setup your project to use be 'QML enabled' and uncheck the 'Run in terminal' box.

Projects -> 'your project name' -> Build & Run -> 'your kit' -> Run -> Enable QML

If you must run your program in a terminal, you need to connect the QML debugger manually:

Debug -> Start Debugging -> Attach to QML port ...

Setup pokemon in your source code

To see an example how to integrate the debugger with your C++ code take a look at example.cpp.

Start your program in the debugger and place a breakpoint in any of your Lua files.

Disable debugging

You can disable Lua debugging by defining POKEMON_NDEBUG in your project. If defined you no longer need to link to the pokemon static/shared library.

Compatibility

You need to build QtCreator from source using the current master branch.
The debugger has been tested with Lua 5.1 and 5.2 on Linux (x86_64).
The Windows implementation is a stub and doesn't work right now.

Caveats

QtCreator will always force evaluation of the 'this' expression which has no counterpart in Lua
