# RDoc::ERBIO

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

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

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

### Public Class Methods

new(str, safe_level = nil, trim_mode = nil, eoutvar = 'io') click to toggle source

Defaults `eoutvar` to 'io', otherwise is identical to ERB's initialize

    # File lib/rdoc/erbio.rb, line 22
    def initialize str, safe_level = nil, trim_mode = nil, eoutvar = 'io'
      super
    end

### Public Instance Methods

set_eoutvar(compiler, io_variable) click to toggle source

Instructs `compiler` how to write to `io_variable`

    # File lib/rdoc/erbio.rb, line 29
    def set_eoutvar compiler, io_variable
      compiler.put_cmd    = "#{io_variable}.write"
      compiler.insert_cmd = "#{io_variable}.write"
      compiler.pre_cmd    = []
      compiler.post_cmd   = []
    end
