Markdown4D is a CommonMark / GFM markdown library written in Delphi. It parses markdown into a typed AST, renders HTML, writes markdown back out, and ships custom-drawn viewer and editor components for VCL and FMX. Everything is plain Object Pascal on top of the RTL; rendering happens on a canvas, without an embedded browser.
Install via dpm CLI
