I've spent quite of a time commenting the central classes of athens, hope that's helpful.

Re: [Pharo-dev] Formatting dates

>>Date today printFormat: #(3 2 1 0 1 1 2) Wait, that's what I was trying for, initially (although it's not super-clear). I did not get that I could use 0 (or apparently a bunch of other characters) as a separator. I didn't see this code at the bottom of printOn:format: (formatArray at: 4) ~= 0

Good to know, thanks. That looks cool.

>>Why not "%04d%02d%02d" % [d.year, d.month, d.day] ? Probably because I'm not super-comfortable with all of Ruby's many, many, many features. >>Chris has already given a near solution. You just need to "select: #isDigit" on the end of his answer to get exactly what you want.<< I figured there was a good way to use "select:" but couldn't think of it, thanks. Date today yyyymmdd select: #isDigit is not bad, though I'd think you should be able to set the separator somehow (or remove it, as in my case).

well I just asked if there is any kind of Documentation about Athens . Or should I just read the code and ask questions ?

Exactly, it would cause the same problem as we have with overrides in monticello
