Anselm Wagner submitted an update to the
robotkarol
package.
Version: 3.9 2026-09-23

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.
This package is located at https://mirrors.ctan.org/macros/luatex/latex/robotkarol More information is at https://ctan.org/pkg/robotkarol
Thanks for the upload. For the CTAN Team Manfred Lotz CTAN is run entirely by volunteers and supported by TeX user groups. Please join a user group or donate to one, see https://ctan.org/lugs .
