Overview

HTML Filter that converts AsciiDoc text into HTML.

This filter is different from most in that it can take a non-HTML as input. It must be used as the first filter in a pipeline.

This filter does not write any additional information to the context hash.

Examples

require 'html/pipeline'
require 'html/pipeline/asciidoc_filter'

filters = [
  HTML::PipelineExt::AsciiDocFilter,
  HTML::Pipeline::SanitizationFilter,
  HTML::Pipeline::ImageMaxWidthFilter,
  HTML::Pipeline::EmojiFilter,
  HTML::Pipeline::MentionFilter,
  HTML::Pipeline::AutolinkFilter,
  HTML::Pipeline::TableOfContentsFilter,
  HTML::Pipeline::SyntaxHighlightFilter
]

context = {
  :asset_root => 'https://github.global.ssl.fastly.net/images/icons/emoji'
}

pipeline = HTML::Pipeline.new filters, context
pipeline.setup_instrumentation
