crhtml2markdown is both a Crystal library and command line interface for converting HTML documents into Markdown format. The project aims to offer a simple API that can be embedded in other Crystal applications while also providing an easy to use binary for quick conversions on the command line. At this early stage the conversion only extracts the textual content from the HTML input. Future releases will add proper Markdown rendering of elements.

The library is currently in its early planning stage. The documentation lays out the goals and how to contribute before any implementation begins.

Add this shard to your project's shard.yml:

dependencies:
  crhtml2markdown:
    github: ipepe-oss/crhtml2markdown

Then run shards install to fetch the dependency. Once the project publishes releases, you will be able to use a version constraint instead of pointing to the GitHub repository.

When installed as a shard you can use crhtml2markdown as a library:

require "crhtml2markdown"

markdown = Crhtml2markdown.convert("<p>Hello</p>")

The project provides a command line interface:

$ crhtml2markdown input.html > output.md

After cloning the repository run the specs to ensure the environment is set up correctly:

crystal spec

Code style follows Crystal's formatter. Run crystal tool format before submitting patches.
