How to add a preprocessor define

[japhib]

Very cool project btw!

I was going to ask a question about how to make a preprocessor define when running this project from the command line. But with a bit of extra Googling, I was able to figure it out. So I'm just leaving the answer here in case it's useful to anyone else!

To define a C# preprocessor symbol, you'd normally (i.e. with the actual C# compiler) use the command line switch /define:MY_SYMBOL. So in this project you wrap that with the -csc option, like this: -csc '/define:MY_SYMBOL'.

Now you can have conditional compilation in your C# code, like so: (assuming you define USE_LUA when compiling to Lua:)

public string GetPlatform()
{
#if USE_LUA
    return "lua";
#else
    return "csharp";
#endif
}
