support nested search

no idea what should happen if the CARD DEF returns multiple cards. I'm content not to support that just yet.

Were you thinking of CARD DEF as something in {}s? (and thus able to return more than one card?) How about just making it simply the name of a card?

If you're talking about what the whole thing returns, i thought the point was that that it could return more than one card (eg all the Tickets that aren't closed). Probably i'm missing something obvious here...

a card name is the simplest form of card def. so, yes, the simple case would be something like:

"returned_by":"Closed Cards"

where Closed Cards is a card name. The multiple card thing I was talking about is that you could do something like

"returned_by":{"type":"Search","edited_by":"John Abbe"}

which would give you all of the cards returned by any search card John Abbe had edited. I don't know of a good use case right now, and it could be hard (or not?), but it would be consistent with how WQL generally works.

As I was implementing I realized found_by would be a little shorter and a tad less geeky. For now I just implemented the simple form.

(I think we'd need more of evidence of need before we decided to implement the multi thing.)

actually, I figured out the need. Daisy chaining, as in being able to refer to _left in found_by. So the multiple thing is now implemented, too.

testing on http://sandwagn.wagn.org/wagn/WQL_testing - definitely at least some breakage (late for cooking dinner...)

_self in WQL refers to the card on the left. If you refer to _left in Sort By name+*rform, then in "User+*type_cards+sort by name", self= 'U+*t', left=User, and right="*type cards". Since User is not a search card, it breaks.

Almost ready to close. Wanted to test what Ethan referred to as, "Daisy chaining, as in being able to refer to _left in found_by." but not getting it. Say more?

--John Abbe.....Thu Apr 23 16:32:08 -0700 2009

I just meant the kind of thing we wanted to do with "by update" or "by name". chaining bits of WQL together via plus cards.

--Ethan McCutchen.....Fri Apr 24 12:02:49 -0700 2009

(in the WQL itself it will usually be _self, not _left)

--Ethan McCutchen.....Fri Apr 24 12:03:37 -0700 2009

phew. was worried you were talking about a whole 'nother category of thing.

--John Abbe.....Fri Apr 24 16:07:08 -0700 2009

Note that when you use found_by, you lose the order, so reverse order+*right+*structure doesn't do what you might want it to.
