class RDoc::Comment
A comment holds the text comment for a RDoc::CodeObject
and provides a unified way of cleaning it up and parsing it into an RDoc::Markup::Document.
Each comment may have a different markup format set by format=
. By default ‘rdoc’ is used. The :markup: directive tells RDoc
which format to use.
See Directive for Specifying RDoc Source Format at RDoc::MarkupReference
.

# File lib/rdoc/comment.rb, line 95 def extract_call_seq method # we must handle situations like the above followed by an unindented first # comment.

Look for a ‘call-seq’ in the comment to override the normal parameter handling. The :call-seq: is indented from the baseline. All lines of the same indentation level and prefix are consumed.
For example, all of the following will be used as the :call-seq:
# :call-seq: # ARGF.readlines(sep=$/) -> array # ARGF.readlines(limit) -> array # ARGF.readlines(sep, limit) -> array # # ARGF.to_a(sep=$/) -> array # ARGF.to_a(limit) -> array # ARGF.to_a(sep, limit) -> array

Sets the format of this comment and resets any parsed document

Normalizes the text. See RDoc::Text#normalize_comment
for details

Parses the comment into an RDoc::Markup::Document. The parsed document is cached until the text is changed.

Removes private sections from this comment. Private sections are flush to the comment marker and start with --
and end with ++
. For C-style comments, a private marker may not start at the opening of the comment.
