For those interested in getting Battery to file in right:
1) edit ThingLab.cs and change 'nil subclass: #SetConstraint' into 'Constraint subclass: #SetConstraint' 2) repeat this for SetMembershipConstraint 3) copy the class definition of SetConstraint and rename #SetConstraint to ConditionalConstraint 4) change the string 'mask: nil' in all thing files which have 'showPicture:' and 'mask: nil' in it to 'fillColor: nil' 5) file ThingLab.cs in 6) file Battery.st in 7) open a ThingLab browser and enjoy
Currently I'm busy getting all 'things' in a 'file in-able and view-able' state. Anyone out there doing the same?
To Dan:
The following classes and methods are missing:
ConditionConstraint, ExprEquality, transpose, methodsNotUniqueState
Any chance you've got them?
Regards, Reinier.
Reinier, this is GREAT!
I do have the sources from which I started, and I will check after dinner for the missing items. I'll also dig up the file pointer to the other sources at U of W. I don't recognize any of these as items that I deleted, though.

Dan,
Thanks very much for resurrecting Thinglab. I had forgotten how much fun it is to play with.

Yes, I also fixed the problems with Battery, but couldn't mail them out last night because my home account was not on the squeak list. I also fixed some bugs in delete in the ThingLab Browser that required hacking DisplayRegionHack; I'll send them out as soon as I can.
I'm currently stuck on filing in ElectricSwitch, because it needs ConditionConstraint. If Dan doesn't have one, I'll probably tack a stab at writing it.
Right now, I'm keeping a ThingLabFixes changeset where this stuff is going. If everyone who is working on ThingLab could send their fixes to someone with a website, we could keep them all together. I can't be the central point, as I don't have enough space on a public webserver anywhere, but I'd be glad to help in coordinating the fixes.
There is one problem with keeping the fixes in a changeset. According to some of the class comments, prototypes won't be filed out with the classes or changes, so for any changes in prototype settings in the "things" file, we would have to edit the fileins directly. Or does anyone have a better solution?
ConditionConstraint, ExprEquality, transpose, methodsNotUniqueState
