[Moose-dev] Re: FAME not ensuring

I have a big proposal but I won’t have time to implement it :(.

As for fame it would be nice to change something. If the idea is gust about getting a class we can call it getClass:. If it should really ensure, then if class metamodel is missing it should be created. I can do that, the question is what is the grand vision.

In general I like to have the tools that think for me. And then to tweak them if needed. For example to export something to MSE you can just export all instance variables buy default and then someone could add meta descriptions to change the behaviour to suite his needs. Same goes for Moose. The Finder could show all instance variables. And then if we need to improve it, we could tweak it. As for me the entry level is too high. It would be nice if we could tell people something like: you can browse whatever you want. Now when you need to make it better you can use this, and that.

This is the thing I experienced with FAME. I followed Moose methods of MSE exporting. It was really hart. You can get a class of each object. You can check all the methods of that class for FAME annotations. So what is the reason of creating a separate meta tower and specifying explicitly all the classes?

But as I’ve already told, I don’t have time to do something like this at the moment, moreover I have no idea if anyone else likes this. But FAME method should be fixed :).

Hi Yuriy,

This kind of messages are not particularly useful for anything.

Let's try to transform it into something positive. Are you unhappy with the behavior or with the name? Do you have an actual proposal for improvement?

So if I’m not mistaken _ensure_ is meant to create referred data if it’s missing. But when you look at:

ensureClass: var

    var isBehavior
            ifTrue: [ ^classDict at: var ].
    var isSymbol
            ifTrue: [
                    ^classDict at: (self class environment at: var)
                                    ifAbsent: [ metaDict at: var asString ]].
    var isString
            ifTrue: [ ^metaDict at: var ].

    [ false ] assert.

it’s not ensuring anything. Isn’t there supposed to be something like:

metaDict at: var asString ifAbsent: [ self processClass: var asClass ]

This really frustrates me about FAME. You cannot tell it "someObj asMSE”. You have to write a tons of pragmas, then do some shenanigans with metamodels and only then you can get serialisation working. Looks like stone age. Sorry for jumping on all the things like that, it’s just that Moose - related things remind me of Java…
