Haxe: add @:build metadata to all classes in project

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())')

Is it possible to distinguish between standart or library classes and project classes? Currently I've added this code, but this is ugly: var module = Context.getLocalModule(); if (module == 'DebugRuntime' || module.indexOf('haxe') == 0 || module.indexOf('flash') == 0) return null; – Kaenel

You can make use of the pathFilter argument. – Farly

Do not see how can I use it. It allows to filter only one prefix. But most projects have a lot of different packages. I think it is possible to filter based on file path and get file path from Context.CurrentPos, but for this I need project source paths. – Kaenel
