Subject: Bug in mp-xbox.mpxl (circleit)
Date: Wed, 22 Dec 2021 14:33:10 +0100 [thread overview]
Message-ID: <76829BC8-F9C5-4A63-96EE-72B4325BDA5E@me.com> (raw)

Hi list,
I realized that circleit throws an error.
It works fine if I replace boxes_generic_declare by boxes_declare in line 244 in mp-xbox.mpxl
rboxit is probably affected as well, but I did not test that.
MWE:
\startMPinclusions
input boxes;
\stopMPinclusions
\startMPpage
circleit.a(textext("$X$"));
drawboxed(a);
\startMPpage
The error (truncated) message:
metapost > initializing instance 'metafun:1' using format 'metafun' and method 'default'
metapost > loading 'metafun' as 'metafun.mpxl' using method 'default'
metapost > initializing number mode 'scaled'
