Get a single optional argument from the command line. If more than one argument is given, return only the first. Return nil if none are given.
Parse and return a Time from string
Returns a hash of default options used by the Ruby iseq compiler.
For details, see InstructionSequence.compile_option=.
Sets the default values for various optimizations in the Ruby iseq compiler.
Possible values for options include true, which enables all options, false which disables all options, and nil which leaves all options unchanged.
You can also pass a Hash of options that you want to change, any options not present in the hash will be left unchanged.
Possible option names (which are keys in options) which can be set to true or false include:
:inline_const_cache
:instructions_unification
:operands_unification
:peephole_optimization
:specialized_instruction
:stack_caching
:tailcall_optimization
:trace_instruction
Additionally, :debug_level can be set to an integer.
These default options can be overwritten for a single run of the iseq compiler by passing any of the above values as the options parameter to ::new, ::compile and ::compile_file.
Iterates over each option, passing the option to the block.
Add a command-line option and handler to the command.
See OptionParser#make_switch for an explanation of opts.
handler will be called with two values, the value of the argument and the options hash.
If the first argument of add_option is a Symbol, it’s used to group options in output. See ‘gem help list` for an example.
Remove previously defined command-line argument name.
Merge a set of command options with the set of default options (without modifying the default option hash).
Handle the given list of arguments by parsing them and recording the results.
A recommended version for use with a ~> Requirement.
Specifies the rdoc options to be used when generating API documentation.
Usage:
spec.rdoc_options << '--title' << 'Rake -- Ruby Make' << '--main' << 'README' << '--line-numbers'
Sets rdoc_options to value, ensuring it is an array. Don’t use this, push onto the array instead.
