Updates for the Author proposal:

    - Completely separate the model from the UI.  Author should be a

"pure domain object." The PerSe methods are no longer needed.

    - Instead, let Utilities class take responsibility for employing

Squeak UI-elements to set the current Author attributes, as well as for being the "convenient" way to access these attributes.

    - Since we are reifying an Author from a String, it is now treated

as a whole Author object, rather than just a String-holder. Allow multiple Author instances to exist and the #current Author can be swapped out with another Author instance.

So other than violent agreement that

• Utilities must die because it is antimodular
• we want a real Author, not a collection of class side methods,

the only thing I see is that noone has actually done the work.

Simply moving a global from one place (Utilities) to another place (a Singleton named "Author") gives us better modularity but does not, IMO, give us a "real Author". There is no new functionality for the system, it's still just a global for accessing the initials.

Author is a "who" of ANY domain -- very common! Sure, Environments can help *developers* get around that, but is it a good deal in exchange for our glorified-global-String bucket? Do we want Squeak to be strictly a "Smalltalk IDE for hard-core developers" or can it also be a "Personal Computing Environment" accessible to a much wider, less-technical, audience? I just don't see that latter group going into the "meta" of importing/exporting classes, do you?

Until we have more use-cases than simply a "holder for the authorInitials", I think SystemAuthor, or SqueakAuthor, or Developer, or CurrentAuthor, or any number of other suggestions would be better. I know just plain "Author" looks, types, and sounds nicer, but it's too "grand" for how little value it adds to the system. We can claim our desired modularity with something that has no chance of making the system less-accessible.

I'm not fussed about the name. I'm fussed about the modularity issues.

Eventually, when Environments are done and dusted, and embedded everywhere, I'd like to see an image ship with a personalised Environment, and you have to jump through a hoop to even access the global Environment, the thing we're currently hacking in. We're not there yet though.

Two things about the implementation:

• using #isOctetCharacter is not good enough. When I wrote ascii, I meant

the 7-bit US-ASCII characters. For example $á is both #isOctetCharacter and #isAlphaNumeric, but I don't think it should appear in a method's timestamp.

• some methods have Smalltalk123 as author

I'm not fussed about the name. I'm fussed about the modularity issues.

Cool, me too.

If we discover some responsibilities we want for our SystemAuthor besides its #initials, I'll welcome it. Until then, I'd be happy enough with:

Smalltalk authorInitials

Well, even if SystemAuthor held a single piece of info (and the plan was to hold both initials and full name), that would be sufficient to remove two class vars from Utilities. A pair of large nails in its coffin!

Eventually, when Environments are done and dusted, and embedded everywhere, I'd like to see an image ship with a personalised Environment, and you have to jump through a hoop to even access the global Environment, the thing we're currently hacking in. We're not there yet though.

So.

I'd really like to see Author stuff ripped out of Utilities, with deprecated Utilities methods delegating to a global current user slot containing a decent object encapsulating what an Author is.

Forget namespace clashes. That's what Environments are for!

Did you review the discussion from back then? The problem with this proposal was it doesn't go far enough. IIRC, by not having a clear picture how we would support multiple Author's, the change ends up being little more than an API change for accessing the global author; a "place to put some methods"; rather than integrating a first-class Author into the system object model.

If we are going to rob the global namespace of such a prominent class name like "Author" from all external domains (or else force them to use Environments?), then we cannot half-ass it. We are not going to trade "Author" for just a global-slot holder. It needs to become an integral part of the system's object model.
