Thanks for the info Mike. I'll put my compile-time IoC framework on hold for now :)

Ah,

Your talking about compiler extensions. There has been discussion about this and in a new compiler prototype this will be entirely possible along with a full configurable and customizable front and back end for a compile session.

A ways down the road as there are some very interesting developments at the moment with some other things...

Having metadata as first class citizens would be great but its not what i was talking about - clearly my fault as no-one gets what i mean ;)

In the same way that adding [Bindable] to a property causes compiler to add extra code in form of watchers and listeners, if i add my own metatag i'd like to be able to tell the compiler what to do with it.

A simple example...

i add [MyFabLoggingTag] to my code and compiler replaces it with trace("constructor"); when it finds it in a constructor, trace("myMethod()", arg1, arg2); when it finds tag in a method etc.

In essence, anything that can be done with reflection, could be done at compile time instead.

Hope that makes sense?

Hi,

I don't know if what Lee is talking about is high level or low level. High level -keep-as3-metadata has been around for eons but lowlevel language support does not exist.

There is actually a JIRA ticket for "Make metadata First class citizens" that was talked about.

I'm going to be working on that in the future. So just like Java, metadata can be compile time checked and would automatically aid IDE's for code completion.

Basically, it would make a metadata annotation like a class type definition.

Actually it is possible.
Robotlegs uses it extensively.

Hi all,

I dont know enough (i.e. anything) about the flex compilers so bear with
me...

How difficult would it be to get the compiler to process custom metatags (e.g. as currently done with [Bindable])? I'm assuming it's not already
posssible as i've found no mention of it by googling.
