FPC-markdown

Markdown Processor for FPC.

Basic Information

This is a Pascal (FPC) 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/)

• Enhanced TxtMark dialect (translated from https://github.com/rjeschke/txtmark)

• Almost complete support for CommonMark dialect (translated from http://commonmark.org/)

Wishlist: PEGDown (Github dialect).

All you need to use the library is FPC version 3.0.4 or newer.

Using the Library

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.UnSafe := 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

The demo folder contains two demonstrative Lazarus programs, the most advanced, MarkdownHTML, needs the HTMLViewer control.

There is also a basic editor at (https://github.com/mriscoc/mdEditor) with syntax highlight for pascal, c, html and vhdl
