From b0f98a43381486995b99ed79e0eabb3af149dbf3 Mon Sep 17 00:00:00 2001 From: stuebinm Date: Tue, 9 Mar 2021 01:23:23 +0100 Subject: Add simple support for cindyjs Notably, the error output (in case of compiler errors) is generated by overwriting the builtin console.error-function, which is a horrible idea for many reasons, but there isn't really any other way right now. --- public/build/Cindy.js |
