= DBF DBF is a small fast library for reading dBase, xBase, Clipper and FoxPro database files. It is written completely in Ruby and has no external dependencies. Copyright (c) 2006-2008 Keith Morrison <firstname.lastname@example.org, www.infused.org> * Official project page: http://rubyforge.org/projects/dbf * API Documentation: http://dbf.rubyforge.org/docs * To report bugs: http://www.rubyforge.org/tracker/?group_id=2009 * Questions: Email email@example.com and put DBF somewhere in the subject line == Features * No external dependencies * Fields are type cast to the appropriate Ruby types * Date/Time fields are returned as either a Time or Date object. Date will only be used if the date is out of range for Ruby's built in Time class. * Ability to dump the database schema in the portable ActiveRecord::Schema format. == Installation gem install dbf == Basic Usage require 'rubygems' require 'dbf' table = DBF::Table.new("old_data.dbf") # Print the 'name' field from record number 4 puts table.record(4).name # Attributes can also be accessed using the column name as a Hash key puts table.record(4).attributes["name"] # Print the 'name' and 'address' fields from each record table.records.each do |record| puts record.name puts record.email end # Find records table.find :all, :first_name => 'Keith' table.find :all, :first_name => 'Keith', :last_name => 'Morrison' table.find :first, :first_name => 'Keith' table.find(10) == Migrating to ActiveRecord An example of migrating a DBF book table to ActiveRecord using a migration: require 'dbf' class CreateBooks < ActiveRecord::Migration def self.up table = DBF::Table.new('db/dbf/books.dbf') eval(table.schema) table.records.each do |record| Book.create(record.attributes) end end def self.down drop_table :books end end == Command-line utility A small command-line utility called dbf is installed along with the gem. $ dbf -h usage: dbf [-h|-s|-a] filename -h = print this message -s = print summary information -a = create an ActiveRecord::Schema == Limitations and known bugs * DBF is read-only * Index files are not used == License (The MIT Licence) Copyright (c) 2006-2008 Keith Morrison <firstname.lastname@example.org> Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
