Method: RDoc::Markup::Parser#build_verbatim

Defined in:
lib/rdoc/markup/parser.rb

#build_verbatim(margin) ⇒ Object

Builds a Verbatim that is indented from margin.

The verbatim block is shifted left (the least indented lines start in column 0). Each part of the verbatim is one line of text, always terminated by a newline. Blank lines always consist of a single newline character, and there is never a single newline at the end of the verbatim.
