Markdown Processor

A Markdown Processor Library for Delphi, to process/convert markdown files to HTML.

Latest Version 1.1.0 - 16 Dec 2024

============

Basic Information

This is a Pascal (Delphi) library that processes markdown to HTML. At present the following dialects of markdown are supported:

• The Daring Fireball dialect (see https://daringfireball.net/projects/markdown/)
• Almost complete support for CommonMark dialect (translated from http://commonmark.org/)
• Enhanced TxtMark dialect (translated from https://github.com/rjeschke/txtmark)

Using the Library with Delphi

Declare a variable of the class TMarkdownProcessor:

     var
       md : TMarkdownProcessor;

Create a TMarkdownProcessor (MarkdownProcessor.pas) of the dialect you want:

       md := TMarkdownProcessor.createDialect(mdDaringFireball)

Decide whether you want to allow active content

       md.AllowUnSafe := true;

Note: you should only set this to true if you need to - active content can be a significant safety/security issue.

Generate HTML fragments from Markdown content:

       html := md.process(markdown); 

Note that the HTML returned is an HTML fragment, not a full HTML page.

Do not forget to dispose of the object after the use:

       md.free

Large rework was made for adding support for tables, math formulas, etc.

Examples

this library is used in two projects:

• MarkdownShellExtensions

A collection of tools for markdown files, to edit and view content, with an advanced Editor:

• MarkdownHelpViewer

An integrated help system based on files in Markdown format (and also html), for Delphi applications:
