From 95279fbf6dfeb43d80590740a9259d7caa614177 Mon Sep 17 00:00:00 2001 From: Mavridis Philippe Date: Sat, 5 Feb 2022 17:44:26 +0000 Subject: Add tdemarkdown part - embeddable lightweight markdown viewing component. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit TDEMarkdown is based on the md4c library and using TDEHTML for rendering its output. For enhanced safety, on HTML widget is turned off everything we don't need for viewing. It integrates nicely into Konqueror and supports both Commonmark and GitHub markdown syntaxes.
