Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment. To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org). ## Contributing Bug reports and pull requests are welcome on GitHub at https://github.com/ruby/base64. base64-0.2.0/Rakefile000066400000000000000000000003061452236030000142340ustar00rootroot00000000000000require "bundler/gem_tasks" require "rake/testtask" Rake::TestTask.new(:test) do |t| t.libs << "test" t.libs << "lib" t.test_files = FileList["test/**/test_*.rb"] end task :default => :test base64-0.2.0/base64.gemspec000066400000000000000000000020751452236030000152250ustar00rootroot00000000000000name = File.basename(__FILE__, ".gemspec") version = ["lib", Array.new(name.count("-")+1).join("/")].find do |dir| break File.foreach(File.join(__dir__, dir, "#{name.tr('-', '/')}.rb")) do |line| /^\s*VERSION\s*=\s*"(.*)"/ =~ line and break $1 end rescue nil end Gem::Specification.new do |spec| spec.name = name spec.version = version spec.authors = ["Yusuke Endoh"] spec.email = ["mame@ruby-lang.org"] spec.summary = %q{Support for encoding and decoding binary data using a Base64 representation.} spec.description = %q{Support for encoding and decoding binary data using a Base64 representation.} spec.homepage = "https://github.com/ruby/base64" spec.required_ruby_version = Gem::Requirement.new(">= 2.4") spec.licenses = ["Ruby", "BSD-2-Clause"] spec.metadata["homepage_uri"] = spec.homepage spec.metadata["source_code_uri"] = spec.homepage spec.files = ["README.md", "LICENSE.txt", "lib/base64.rb"] spec.bindir = "exe" spec.executables = [] spec.require_paths = ["lib"] end base64-0.2.0/bin/000077500000000000000000000000001452236030000133405ustar00rootroot00000000000000base64-0.2.0/bin/console000077500000000000000000000005251452236030000147320ustar00rootroot00000000000000#!/usr/bin/env ruby require "bundler/setup" require "base64" # You can add fixtures and/or initialization code here to make experimenting # with your gem easier.

# \Module \Base64 provides methods for: # # - Encoding a binary string (containing non-ASCII characters) # as a string of printable ASCII characters. # - Decoding such an encoded string. # # \Base64 is commonly used in contexts where binary data # is not allowed or supported: # # - Images in HTML or CSS files, or in URLs. # - Email attachments. # # A \Base64-encoded string is about one-third larger that its source. # See the {Wikipedia article}[https://en.wikipedia.org/wiki/Base64] # for more information. # # This module provides three pairs of encode/decode methods. # Your choices among these methods should depend on: # # - Which character set is to be used for encoding and decoding. # - Whether "padding" is to be used. # - Whether encoded strings are to contain newlines. # # Note: Examples on this page assume that the including program has executed: # # require 'base64' # # == Encoding Character Sets # # A \Base64-encoded string consists only of characters from a 64-character set: # # - ('A'..'Z'). # - ('a'..'z'). # - ('0'..'9'). # - =, the 'padding' character. # - Either: # - %w[+ /]: # {RFC-2045-compliant}[https://datatracker.ietf.org/doc/html/rfc2045]; # _not_ safe for URLs. # - %w[- _]: # {RFC-4648-compliant}[https://datatracker.ietf.org/doc/html/rfc4648]; # safe for URLs. # # If you are working with \Base64-encoded strings that will come from # or be put into URLs, you should choose this encoder-decoder pair # of RFC-4648-compliant methods: # # - Base64.urlsafe_encode64 and Base64.urlsafe_decode64. # # Otherwise, you may choose any of the pairs in this module, # including the pair above, or the RFC-2045-compliant pairs: # # - Base64.encode64 and Base64.decode64. # - Base64.strict_encode64 and Base64.strict_decode64. # # == Padding # # \Base64-encoding changes a triplet of input bytes # into a quartet of output characters. # # Padding in Encode Methods # # Padding -- extending an encoded string with zero, one, or two trailing # = characters -- is performed by methods Base64.encode64, # Base64.strict_encode64, and, by default, Base64.urlsafe_encode64: # # Base64.encode64('s') # => "cw==\n" # Base64.strict_encode64('s') # => "cw==" # Base64.urlsafe_encode64('s') # => "cw==" # Base64.urlsafe_encode64('s', padding: false) # => "cw" # # When padding is performed, the encoded string is always of length 4n, # where +n+ is a non-negative integer: # # - Input bytes of length 3n generate unpadded output characters # of length 4n: # # # n = 1: 3 bytes => 4 characters. # Base64.strict_encode64('123') # => "MDEy" # # n = 2: 6 bytes => 8 characters. # Base64.strict_encode64('123456') # => "MDEyMzQ1" # # - Input bytes of length 3n+1 generate padded output characters # of length 4(n+1), with two padding characters at the end: # # # n = 1: 4 bytes => 8 characters. # Base64.strict_encode64('1234') # => "MDEyMw==" # # n = 2: 7 bytes => 12 characters. # Base64.strict_encode64('1234567') # => "MDEyMzQ1Ng==" # # - Input bytes of length 3n+2 generate padded output characters # of length 4(n+1), with one padding character at the end: # # # n = 1: 5 bytes => 8 characters. # Base64.strict_encode64('12345') # => "MDEyMzQ=" # # n = 2: 8 bytes => 12 characters. # Base64.strict_encode64('12345678') #
