Madeline

Rails gem for running madeline on a pedigree hash

Installation

sudo gem install madeline

Usage

The Madeline::Interface has a single method, draw, which can be passed a string or an open IO object, and returns the Madeline XML. The draw method returns a filename and warnings, or, if a block is passed, yields the file contents and warnings.

require 'rubygems'
require 'madeline'
pedigree_filename, warnings = Madeline::Interface.new.draw(File.open('pedigree.txt', 'r'))

require 'rubygems'
require 'madeline'
pedigree, warnings = Madeline::Interface.new.draw(File.open('pedigree.txt','r')) { |filehandle, warnings|
  puts "warnings #{warnings}"
  pedigree = filehandle.read
}

When creating a Madeline::Interface, you can pass any options that the madeline2 program accepts to the interface and they'll be forwarded. For example, to create an embedded result:

artist = Madeline::Interface.new(:embedded => true)
pedigree_filename, warnings = artist.draw(File.open('pedigree.txt', 'r'))

The default values of all the madeline2 flags are identical to the command-line version.

A Madeline::Error exception will be raised if draw fails for any reason.

Madeline Location

The Madeline::Interface initializer can take a madeline option, overriding the location of the madeline2 program.

artist = Madeline::Interface.new(
  :madeline     => '/usr/local/bin/madeline2'
)
