Quick Start

Example.fan:

using afIoc
using afIocConfig
using afIocEnv

class Example {
    @Inject IocEnv iocEnv             // --> Inject IocEnv service

    @Config { id="afIocEnv.isProd" }  // --> Inject Config values
    @Inject Bool isProd

    new make(|This| in) { in(this) }

    Void wotever() {
        echo("The environment is '${iocEnv.env}'")

        if (isProd) {
            echo("I'm in Production!")
        } else {
            echo("I'm in Development!!")
        }
    }
}

// ---- Standard afIoc Support Classes ----

class Main {
    Void main() {
        registry := RegistryBuilder().addModules([AppModule#, IocEnvModule#, IocConfigModule#]).build.startup
        example  := (Example) registry.dependencyByType(Example#)
        example.wotever()
    }
}

class AppModule {
    static Void bind(ServiceBinder binder) {
        binder.bindImpl(Example#)
    }
}

Run Example.fan from the command line:

C:\> fan Example.fan -env PRODUCTION
[info] [afIocEnv] Setting from environment variable 'env' : development
[info] [afIocEnv] Overriding from cmd line argument '-env' : PRODUCTION
