This is a pure ruby Gemtext to HTML convertor, relying on the gemtext gem

Gemtext is a simple plain text format, similar to Markdown but simpler. It is the official format for pages within Gemini capsules.

For more information on Gemini see the official page

Gemini official page Gemini specification

I've written a separate gem - jekyll-gemini which uses this gem for publishing from your Jekyll blog to a Gemini capsule.

To convert a Gemtext string to an html string

require 'gmi2html'

html_string = Gmi2html::Document.new(my_gemtext_string).to_html

To convert a Gemtext file to an html string

require 'gmi2html'

html_string = File.open('capsule/my_gemtext.gmi', 'r') do |f|
  Gmi2html::Document.new(f).to_html
end
