Which preprocessors does angelscript support?

C++ has those following preprocessors: #define, #undef, #include, #if, #ifdef, #ifndef, #else, #elif and #endif.

It seems that angelscript lacks the #undef and #else preprocessors, do they exist in some other form?
Does anyone know about some documents about angelscript preprocessors on the internet?

 

Maybe you can find some help in the SDK as referenced here: http://www.angelcode.com/angelscript/sdk/docs/manual/doc_samples_incl.html

Not sure what the dev team chose or chose not to implement.

 

I looked it up in the engine: #if, #ifdef, #ifndef, #ifndef, #endif, #define and #include should be working.
This means using #endif then #ifndef should suffice in your case.
#BRK might work - it should allow to set breakpoints within the script when the debugger is active - i.e. when g_debug is set to at least 1. A breakpoint stops the execution of a program to examine (debug) the state of the program when it is reached with the debugger.

The engine looks up for a few script defines: SERVER_ONLY, CLIENT_ONLY, ALWAYS_ONRELOAD.
When SERVER_ONLY is set, the server will not send that script to clients (to verify). At least, i'm pretty sure that when either of those is set hooks won't be called on the wrong side.
I'm not sure what the last one does, but it might not be often useful.
