Module: RDoc

Overview

RDoc produces documentation for Ruby source files by parsing the source and extracting the definition for classes, modules, methods, includes and requires. It associates these with optional documentation contained in an immediately preceding comment block then renders the result using an output formatter.

For a simple introduction to writing or generating documentation using RDoc see the README.

Roadmap

If you think you found a bug in RDoc see CONTRIBUTING@Bugs

If you want to use RDoc to create documentation for your Ruby source files, see Markup and refer to rdoc --help for command line usage.

If you want to set the default markup format see RDoc::Markup@Supported+Formats

If you want to store rdoc configuration in your gem (such as the default markup format) see RDoc::Options@Saved+Options

If you want to write documentation for Ruby files see ::RDoc::Parser::Ruby

If you want to write documentation for extensions written in C see ::RDoc::Parser::C

If you want to generate documentation using rake see Task.

If you want to drive RDoc programmatically, see RDoc.

If you want to use the library to format text blocks into HTML or other formats, look at Markup.

If you want to make an RDoc plugin such as a generator or directive handler see RDoc.

If you want to write your own output generator see Generator.

If you want an overview of how RDoc works see CONTRIBUTING

RDoc is currently being maintained by Eric Hodel <drbrain@segment7.net>.

Dave Thomas <dave@pragmaticprogrammer.com> is the original author of RDoc.

  • The Ruby parser in rdoc/parse.rb is based heavily on the outstanding work of Keiju ISHITSUKA of Nippon Rational Inc, who produced the Ruby parser for irb and the rtags package.

Class Method Details

.home

Seaches and returns the directory for settings.

  1. $HOME/.rdoc directory, if it exists.

  2. The rdoc directory under the path specified by the XDG_DATA_HOME environment variable, if it is set.

  3. $HOME/.local/share/rdoc directory.

Other than the home directory, the containing directory will be created automatically.
