Earmark is a pure-Elixir Markdown converter. It is intended to be used as a library (just call Earmark.as_html), but can also be used as a command-line tool (run mix escript.build first). Output generation is pluggable.

Retired package: Deprecated - Earmark is no longer maintained. Migrate to a replacement, for example MDEx (https://hex.pm/packages/mdex).
