A remote debugger for AngelScript.

asdbg

A remote debugger for AngelScript. Currently in very early stages of development.

Implementation

To implement the debugger into the host application, include asdbg.h. Also, in 1 .cpp file, include it while ASDBG_IMPL is defined.

#define ASDBG_IMPL
#include "asdbg.h"

Then, before the first execution of a script context, initialize the debugger:

asIScriptContext* ctx = engine->CreateContext();
dbg::Initialize(ctx);

Next, define any encoders you may need for variable inspection. An encoder takes a pointer and returns a string representation. Optionally, a decoder takes a pointer and a string representation, and you have to decode the string representation into the pointer. For example, a std::string encoder (for the default ScriptString addon) looks like this:

dbg::Encoder(engine->GetTypeIdByDecl("string"), [](void* ptr) {
  return *(std::string*)ptr;
}, [](void* ptr, const char* set) {
  *(std::string*)ptr = set;
});

When your program is shutting down, call dbg::Release() before the context is released.

dbg::Release();
ctx->Release();
engine->Release();
