Class/Module Index [+]



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

To use:

erbio = '<%= "hello world" %>', nil, nil

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

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 rdoc/erbio.rb, line 22
def initialize str, safe_level = nil, trim_mode = nil, eoutvar = 'io'

Public Instance Methods

set_eoutvar(compiler, io_variable) click to toggle source

Instructs compiler how to write to io_variable

               # File 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   = []
