Anselm Wagner submitted an update to the

robotkarol

package.

Version: 3.9 2026-09-23
License: lppl1.3c

Summary description: Worlds and block programs of the German teaching environment Robot Karol

Announcement text: --------------------------------------------------------------------------------
robotkarol draws worlds and Blockly-style block programs in the visual
style of Robot Karol Online (https://karol.arrrg.de/) for worksheets,
exams and slides.

New in version 3.9: a karolwelt picture can show the start state and
the goal state of a task at once, the way the online exercises do.

The objects take the keys start and ziel -- with the aliases neu and
weg, and the Robot Karol verbs hinlegen/aufheben and setzen/loeschen --
as well as startanzahl and zielanzahl for stacks that grow or shrink.
The environment gained zustand=start|ziel|beides to pick the view,
aufraeumen for tasks whose goal is the empty world, and rahmen and
hervorheben. The new karolweltpaar environment draws one world twice,
as a before-and-after pair, and \karolzustandslegende explains the
symbols. The print mode covers all of this by hatching and dashed
outlines rather than by shades of grey.

Documents that do not use the new keys produce byte-identical output. --------------------------------------------------------------------------------
