1、断点不要直接用rb_add_event_hook，此函数会对使用一些内部处理的地方也会断进来导致循环出错

应该使用debug下的创建tracePoint的效果

m_trace[eCall] = rb_tracepoint_new( 0, RUBY_EVENT_CALL, HookProc, this );

m_trace[eLine] = rb_tracepoint_new( 0, RUBY_EVENT_LINE, HookProc, this );

m_trace[eReturn] = rb_tracepoint_new( 0, RUBY_EVENT_RETURN, HookProc, this );

2、rb_tracepoint_enable 会对point进行调试，不能多次执行，内部没有做判断。必须disable后再enable。

3、堆栈深度有多种获取方式。这里只是其中一种

int32 CMRubyDebuger::GetRunningStackLevel()

{

struct SCallBack

{

static VALUE OnInspector( const rb_debug_inspector_t * pIns, void * p )

{

VALUE bt = rb_debug_inspector_backtrace_locations( pIns );

*(int32 *)p = rb_array_len( bt );

return Qnil;

}

};

int32 nFrameSize = 0;

rb_debug_inspector_open( &SCallBack::OnInspector, &nFrameSize );

return nFrameSize;

}

4、断点行数使用较为简单的处理，按照源码来看，这个v可有可无

rb_trace_arg_t * arg = rb_tracearg_from_tracepoint( v );

int32 currentline = FIX2INT( rb_tracearg_lineno( arg ) );

VALUE vPath = rb_tracearg_path( arg );

CMString source = StringValuePtr( vPath );

5、rb_iv_get及rb_gv_get能获取类成员变量及全局变量，局部变量不能同过跳过堆栈层级获取，按照一个文档说是获取不了。但当前的局部变量，还是可以同过执行一句ruby语句获取，rb_eval_string_protect发挥很大效果
