Hello everyone, those using QR codes in their documents prepared with GNU troff, might welcome a PR¹ for libqrencode, that adds support to generate QR codes drawn with pic(1).
Libqrencode hasn't seen a release in quite some time and seems dormant; if you find the work interesting and have a GitHub account, stating your interest on the PR might help in getting it merged and a new release out. Best Alexis ¹ https://github.com/fukuchi/libqrencode/pull/208
