Haxe：将@：build元数据添加到项目中的所有类

Question

Is it possible to apply my type building macro to all classes in a project without modifying their code?

I'm trying to implement a debugger based on Haxe macros: basically I inject calls to my function between every expression in every function of the class. Currently I have an interface IDebuggable and only code in classes that implement that interface can be stopped at breakpoints.

You can use haxe.macro.Compiler.addGlobalMetadata() for this. This can either be done from an initialization macro or on the command line:

--macro addGlobalMetadata('', '@:build(Build.build())')
