Seems to be identified as TOC

# ...

toc.check becomes #toccheck on github, not toc-check

A variation of #4.

Danger-toc can be used outside of Github. We now default to the GFM parser, support other Kramdown parsers, notably the default markdown. Coming from #7.

Currently takes all headings.

Typically TOC goes under the top title, therefore exclude it from the expected TOC. Avoids an iteration. In the example below the slack-ruby-bot title won't be in the TOC.

Follow https://github.com/dblock/danger-toc/blob/master/RELEASING.md.

If everything starts at level 2 we insert one space too many.

By default we use -.

Currently two spaces.

Example:

require 'kramdown'
require 'html/pipeline'

text = <<TEXT
# Prelude

The quick brown fox jumps over the lazy dog.

## Table of Contents

- [What_is_this?](#what_is_this)

## What_is_this?

The quick brown fox jumps over the lazy dog.
TEXT

puts Kramdown::Document.new(text).to_html

# ...
# <h2 id="whatisthis">What_is_this?</h2>
# ...

MarkdownPipeline = HTML::Pipeline.new [
  HTML::Pipeline::MarkdownFilter,
  HTML::Pipeline::TableOfContentsFilter
]

result = MarkdownPipeline.call text
puts result[:output].to_s

# ...
# <h2>
#   <a id="what_is_this" class="anchor" href="#what_is_this" aria-hidden="true">
#      <span aria-hidden="true" class="octicon octicon-link"></span>
#    </a>What_is_this?
# </h2>

Two different anchors: whatisthis and what_is_this.
Github uses anchor what_is_this.
How the gem "danger-toc" should behave in this case?

@dblock, i need your help.
