Overview

A subclass of ERB that writes directly to an IO. Credit to Aaron Patterson and Masatoshi SEKI.

To use:

erbio = RDoc::ERBIO.new '<%= "hello world" %>', nil, nil

File.open 'hello.txt', 'w' do |io|
  erbio.result binding
end

Note that binding must enclose the io you wish to output on.

Constructor Details

.new(str, safe_level = nil, legacy_trim_mode = nil, legacy_eoutvar = 'io', trim_mode: nil, eoutvar: 'io') ⇒ ERBIO

Defaults eoutvar to ‘io’, otherwise is identical to ERB’s initialize
