Parse and return a Time from string
Sets the preset dictionary and returns string. This method is available just only after Zlib::Deflate.new or Zlib::ZStream#reset method was called. See zlib.h for details.
Can raise errors of Z_STREAM_ERROR if a parameter is invalid (such as NULL dictionary) or the stream state is inconsistent, Z_DATA_ERROR if the given dictionary doesn’t match the expected one (incorrect adler32 value)
Sets the preset dictionary and returns string. This method is available just only after a Zlib::NeedDict exception was raised. See zlib.h for details.
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
:tailcall_optimization
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.
Add a command-line option and handler to the command.
See Gem::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.
Mark a command-line option as deprecated, and optionally specify a deprecation horizon.
Note that with the current implementation, every version of the option needs to be explicitly deprecated, so to deprecate an option defined as
add_option('-t', '--[no-]test', 'Set test mode') do |value, options| # ... stuff ... end
you would need to explicitly add a call to ‘deprecate_option` for every version of the option you want to deprecate, like
deprecate_option('-t') deprecate_option('--test') deprecate_option('--no-test')
Handle the given list of arguments by parsing them and recording the results.
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.
Terminate the application with exit code status, running any exit handlers that might have been defined.
Private method to cleanup attributes, scope, filter, and extensions from using the query component attribute.
Generates new parameters for the algorithm. algo_name is a String that represents the algorithm. The optional argument options is a Hash that specifies the options specific to the algorithm. The order of the options can be important.
A block can be passed optionally. The meaning of the arguments passed to the block varies depending on the implementation of the algorithm. The block may be called once or multiple times, or may not even be called.
For the supported options, see the documentation for the ‘openssl genpkey’ utility command.
pkey = OpenSSL::PKey.generate_parameters("DSA", "dsa_paramgen_bits" => 2048) p pkey.p.num_bits #=> 2048
Returns whether the HTTP session is to be closed.
Terminates the RubyGems process with the given exit_code
Enumerates the parents of directory.
Comes from ripper, called on every parse error, msg is a string
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.
