Method: OptParseBuilder.build_parser

Defined in:
lib/opt_parse_builder.rb

.build_parser {|parser_builder| ... } ⇒ Object

Create a new parser. If called without a block, returns a parser than you can then add arguments to:

arg_parser = OptParseBuilder.build_parser
arg_parser.add do |arg|
  arg.key :force
  arg.on "--force", "Force dangerous operation"
end

If called with a block, yields itself to the block:

arg_parser = OptParseBuilder.build_parser do |args|
  args.add do |arg|
    arg.key :force
    arg.on "--force", "Force dangerous operation"
  end
end

Note that the parser constructed using the block form can still be added onto:

arg_parser.add do |arg|
  arg.key :size
  arg.on "--size=N", Integer, "File size in bytes"
end

Yields:

  • (parser_builder)
