|
|
#
|
|
# === Introduction
|
|
#
|
|
# OptionParser is a class for command-line option analysis. It is much more
|
|
# advanced, yet also easier to use, than GetoptLong, and is a more Ruby-oriented
|
|
# solution.
|
|
#
|
|
# === Features
|
|
#
|
|
# 1. The argument specification and the code to handle it are written in the
|
|
# same place.
|
|
# 2. It can output an option summary; you don't need to maintain this string
|
|
# separately.
|
|
# 3. Optional and mandatory arguments are specified very gracefully.
|
|
# 4. Arguments can be automatically converted to a specified class.
|
|
# 5. Arguments can be restricted to a certain set.
|
|
#
|
|
# All of these features are demonstrated in the examples below. See
|
|
# #make_switch for full documentation.
|
|
#
|
|
# === Minimal example
|
|
#
|
|
# require 'optparse'
|
|
#
|
|
# options = {}
|
|
# OptionParser.new do |opts|
|
|
# opts.banner = "Usage: example.rb [options]"
|
|
#
|
|
# opts.on("-v", "--[no-]verbose", "Run verbosely") do |v|
|
|
# options[:verbose] = v
|
|
# end
|
|
# end.parse!
|
|
#
|
|
# p options
|
|
# p ARGV
|
|
#
|
|
# === Generating Help
|
|
#
|
|
# OptionParser can be used to automatically generate help for the commands you
|
|
# write:
|
|
#
|
|
# require 'optparse'
|
|
#
|
|
# Options = Struct.new(:name)
|
|
#
|
|
# class Parser
|
|
# def self.parse(options)
|
|
# args = Options.new("world")
|
|
#
|
|
# opt_parser = OptionParser.new do |opts|
|
|
# opts.banner = "Usage: example.rb [options]"
|
|
#
|
|
# opts.on("-nNAME", "--name=NAME", "Name to say hello to") do |n|
|
|
# args.name = n
|
|
# end
|
|
#
|
|
# opts.on("-h", "--help", "Prints this help") do
|
|
# puts opts
|
|
# exit
|
|
# end
|
|
# end
|
|
#
|
|
# opt_parser.parse!(options)
|
|
# return args
|
|
# end
|
|
# end
|
|
# options = Parser.parse %w[--help]
|
|
#
|
|
# #=>
|
|
# # Usage: example.rb [options]
|
|
# # -n, --name=NAME Name to say hello to
|
|
# # -h, --help Prints this help
|
|
#
|
|
# === Required Arguments
|
|
#
|
|
# For options that require an argument, option specification strings may include an
|
|
# option name in all caps. If an option is used without the required argument,
|
|
# an exception will be raised.
|
|
# require 'optparse'
|
|
#
|
|
# options = {}
|
|
# OptionParser.new do |parser|
|
|
# parser.on("-r", "--require LIBRARY",
|
|
# "Require the LIBRARY before executing your script") do |lib|
|
|
# puts "You required #{lib}!"
|
|
# end
|
|
# end.parse!
|
|
#
|
|
# Used:
|
|
#
|
|
# bash-3.2$ ruby optparse-test.rb -r
|
|
# optparse-test.rb:9:in `<main>': missing argument: -r (OptionParser::MissingArgument)
|
|
# bash-3.2$ ruby optparse-test.rb -r my-library
|
|
# You required my-library!
|
|
#
|
|
# === Type Coercion
|
|
#
|
|
# OptionParser supports the ability to coerce command line arguments
|
|
# into objects for us.
|
|
#
|
|
# OptionParser comes with a few ready-to-use kinds of type
|
|
# coercion. They are:
|
|
#
|
|
# - Date -- Anything accepted by +Date.parse+
|
|
# - DateTime -- Anything accepted by +DateTime.parse+
|
|
# - Time -- Anything accepted by +Time.httpdate+ or +Time.parse+
|
|
# - URI -- Anything accepted by +URI.parse+
|
|
# - Shellwords -- Anything accepted by +Shellwords.shellwords+
|
|
# - String -- Any non-empty string
|
|
# - Integer -- Any integer. Will convert octal. (e.g. 124, -3, 040)
|
|
# - Float -- Any float. (e.g. 10, 3.14, -100E+13)
|
|
# - Numeric -- Any integer, float, or rational (1, 3.4, 1/3)
|
|
# - DecimalInteger -- Like +Integer+, but no octal format.
|
|
# - OctalInteger -- Like +Integer+, but no decimal format.
|
|
# - DecimalNumeric -- Decimal integer or float.
|
|
# - TrueClass -- Accepts '+, yes, true, -, no, false' and
|
|
# defaults as +true+
|
|
# - FalseClass -- Same as +TrueClass+, but defaults to +false+
|
|
# - Array -- Strings separated by ',' (e.g. 1,2,3)
|
|
# - Regexp -- Regular expressions. Also includes options.
|
|
#
|
|
# We can also add our own coercions, which we will cover soon.
|
|
#
|
|
# ==== Using Built-in Conversions
|
|
#
|
|
# As an example, the built-in +Time+ conversion is used. The other built-in
|
|
# conversions behave in the same way.
|
|
# OptionParser will attempt to parse the argument
|
|
# as a +Time+. If it succeeds, that time will be passed to the
|
|
# handler block. Otherwise, an exception will be raised.
|
|
#
|
|
# require 'optparse'
|
|
# require 'optparse/time'
|
|
# OptionParser.new do |parser|
|
|
# parser.on("-t", "--time [TIME]", Time, "Begin execution at given time") do |time|
|
|
# p time
|
|
# end
|
|
# end.parse!
|
|
#
|
|
# Used:
|
|
# bash-3.2$ ruby optparse-test.rb -t nonsense
|
|
# ... invalid argument: -t nonsense (OptionParser::InvalidArgument)
|
|
# from ... time.rb:5:in `block in <top (required)>'
|
|
# from optparse-test.rb:31:in `<main>'
|
|
# bash-3.2$ ruby optparse-test.rb -t 10-11-12
|
|
# 2010-11-12 00:00:00 -0500
|
|
# bash-3.2$ ruby optparse-test.rb -t 9:30
|
|
# 2014-08-13 09:30:00 -0400
|
|
#
|
|
# ==== Creating Custom Conversions
|
|
#
|
|
# The +accept+ method on OptionParser may be used to create converters.
|
|
# It specifies which conversion block to call whenever a class is specified.
|
|
# The example below uses it to fetch a +User+ object before the +on+ handler receives it.
|
|
#
|
|
# require 'optparse'
|
|
#
|
|
# User = Struct.new(:id, :name)
|
|
#
|
|
# def find_user id
|
|
# not_found = ->{ raise "No User Found for id #{id}" }
|
|
# [ User.new(1, "Sam"),
|
|
# User.new(2, "Gandalf") ].find(not_found) do |u|
|
|
# u.id == id
|
|
# end
|
|
# end
|
|
#
|
|
# op = OptionParser.new
|
|
# op.accept(User) do |user_id|
|
|
# find_user user_id.to_i
|
|
# end
|
|
#
|
|
# op.on("--user ID", User) do |user|
|
|
# puts user
|
|
# end
|
|
#
|
|
# op.parse!
|
|
#
|
|
# output:
|
|
# bash-3.2$ ruby optparse-test.rb --user 1
|
|
# #<struct User id=1, name="Sam">
|
|
# bash-3.2$ ruby optparse-test.rb --user 2
|
|
# #<struct User id=2, name="Gandalf">
|
|
# bash-3.2$ ruby optparse-test.rb --user 3
|
|
# optparse-test.rb:15:in `block in find_user': No User Found for id 3 (RuntimeError)

#
|

# [Argument pattern:]
|

# Acceptable option argument format, must be pre-defined with
|
|
# OptionParser.accept or OptionParser#accept, or Regexp. This can appear
|
|
# once or assigned as String if not present, otherwise causes an

# Float, Time, Array

|
|
# { "jis" => "iso-2022-jp", "sjis" => "shift_jis" }
|
|
#
|
|
# [Long style switch:]
|
|
# Specifies a long style switch which takes a mandatory, optional or no
|
|
# argument. It's a string of the following form:
|
|
# "--switch=MANDATORY" or "--switch MANDATORY"
|
|
# "--switch[=OPTIONAL]"
|
|
# "--switch"
|
|
#
|
|
# [Short style switch:]
|
|
# Specifies short style switch which takes a mandatory, optional or no
|
|
# argument. It's a string of the following form:
|
|
# "-xMANDATORY"
|
|
# "-x[OPTIONAL]"
|
|
# "-x"
|
|
# There is also a special form which matches character range (not full
|
|
# set of regular expression):
|
|
# "-[a-z]MANDATORY"
|
|
# "-[a-z][OPTIONAL]"
|
|
# "-[a-z]"
|
|
#
|
|
# [Argument style and description:]
|
|
# Instead of specifying mandatory or optional arguments directly in the
|
|
# switch parameter, this separate parameter can be used.
|
|
# "=MANDATORY"
|
|
# "=[OPTIONAL]"
|
|
#
|
|
# [Description:]
|
|
# Description string for the option.
|
|
# "Run verbosely"
|
|
#
|
|
# [Handler:]
|
|
# Handler for the parsed argument value. Either give a block or pass a
|
|
# Proc or Method as an argument.
