Babel¶ ↑

• github.com/thyresias/rdoc-babel

Babel is an RDoc formatter producing HTML documentation. The default template is ruby-lang.

You are welcome to propose changes or enhancements, and to contribute alternate templates or style sheets.

• Look and feel inspired from ruby-lang.org (in 2010).

• Dual-frame output, with indexes on the left.

• Search boxes for classes and methods.

• Links to undocumented classes/methods are grayed.

• Highlights the current file/class/method in the left frame.

• Highlights the target method, attribute or constant in the main frame.

• Adds links to ancestor methods/attributes.

• Borrows some ideas (and one icon) from Darkfish.

• Tested on Firefox 125.
  If using the file:// protocol, the “same origin policy” for local files must be turned off:
  about:config > security.fileuri.strict_origin_policy = false

To output documentation formatted by Babel, use the --format/-f RDoc switch. For instance, to generate the documentation for Ruby core and stdlib:

> gem install rdoc-babel
> cd /ruby/src
> rdoc -f babel -a -t "Ruby Core + Stdlib" -o /docs/ruby-core

Using rake:

require 'rdoc/task'

RDoc::Task.new do |t|
  Dir.chdir '/ruby/src'
  rdoc.options <<
    '--format' << 'babel' <<
    '--all'
  t.title = "Ruby Core + Stdlib"
  t.rdoc_dir = '/docs/ruby-core'
end

To make Babel the default format when generating RDoc documentation, define the RDOCOPT environment variable:

RDOCOPT="--format babel"

Babel supports specific options in addition to the standard RDoc options:

--style url, -s

Specifies the URL of a stylesheet that the template should use. The default is “rdoc.css”.

--see-standard-ancestors

Add links to Kernel/Object ancestor methods.

When a method or attribute is defined in a class/module, and is also present in an ancestor, Babel adds a link to the ancestor method/attribute in the description (“See also …”). Unless this option is specified, this annotation is not generated for Object and Kernel ancestor methods.

• Ruby >= 3.1.0 (may work with >= 2.5.0, but untested)

• RDoc >= 6.5.0 (may work with >= 5.0, but untested)
