# RDoc::Markup::Formatter

Base class for `RDoc` markup formatters

Formatters are a visitor that converts an `RDoc::Markup` tree (from a comment) into some kind of output. `RDoc` ships with formatters for converting back to rdoc, ANSI text, HTML, a Table of Contents and other formats.

If you'd like to write your own `Formatter` use `RDoc::Markup::FormatterTestCase`. If you're writing a text-output formatter use `RDoc::Markup::TextFormatterTestCase` which provides extra test cases.

### Constants

InlineTag

  Tag for inline markup containing a `bit` for the bitmask and the `on` and `off` triggers.
