Markdown Processor for Pascal (Delphi/FPC)
This is a Pascal library that processes to markdown to HTML. At present the following dialects of markdown are supported:
- The Daring Fireball dialect (see https://daringfireball.net/projects/markdown/) (translated from https://github.com/rjeschke/txtmark)
- The CommonMark Specification (see https://spec.commonmark.org/0.28) (not quite complete. Stil to do: link references)
- Github Flavored Markdown
Using the Library
Create a TMarkdownProcessor (MarkdownProcessor.pas) of the dialect you want:
var md : TMarkdownProcessor; html : string; begin md := TMarkdownProcessor.createDialect(mdDaringFireball)
Decide whether you want to allow active content (not supported for CommonMark)
md.UnSafe := true;
Note: you should only set this to true if you need to - active content can be a signficant safety/security issue.
Generate HTML from the Markdown content:
html := md.process(markdown);
Note that the HTML returned is an HTML fragment, not a full HTML page.
Internally, the library includes a comprehensive set of unit tests. For CommonMark, the tests are those provided as part of the CommonMark spec.
- Any unicode version of Delphi
To use the code:
- clone the repository, and use the units in \source
To run the tests:
- Test Program is markdown\delphi\MarkDownTests.dproj
- you also need FastMM4, and DUnitX (and update the search paths)
- you'll have to update the run parameters to set the current directory to the root directory for your clones of the reop
- if you don't have TestInsight installed (you very much should!) you'll have to remove the TESTINSIGHT define in the project options
- tested with FPC 3.2.0+ (but no particular reason it shouldn't work with earlier versions)
- tested with win32, win64, linux64, OSX (but no reason it shouldn't work on other platforms)
To use the code:
- clone the repository, and compile the MarkdownEngine package in source
- alternatively, you can use the units in \source directly
To run the tests:
- Test Program is markdown/fpc/MarkdownTestProgram.lpi
- you need to provide command line parameter -mdRoot [x] where [x] is the location of the repo on your local drive
- depends on https://github.com/grahamegrieve/lazarus-ide-tester
