Anselm Wagner submitted an update to the
robotkarol
package.
Version: 4.0 2026-10-31
License: lppl1.3c
Summary description: Worlds and block programs of the German teaching environment Robot Karol
Announcement text:
robotkarol has been updated to version 4.0. The package now exchanges tasks with Robot Karol Online: task files downloaded from the online editor (JSON) can be read with \karoljsonlesen and set as worlds showing start and goal state in one picture (\karolweltaus, or quelle= on karolwelt), or turned into the LaTeX source one would otherwise type (\karolquelltext). Conversely, worlds marked with export=sheet/1 are written to a JSON file by \karoljsonschreiben and can be uploaded to Robot Karol Online; programs and check scripts of an imported task survive a round trip. Reading and writing need neither shell escape nor external tools. The interface lives in the new file robotkarol.lua. Documents not using it typeset exactly as with version 3.10.
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 Erik Braun 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 .
