Returns true if and only if the current severity level allows for the printing of WARN messages.

Sets the severity to WARN.

Log a WARN message.

See info for more information.

Initializes a new instance and evaluates the optional block in context of the instance. Arguments args are passed to new, see there for description of parameters.

This method is deprecated, its behavior corresponds to the older new method.

Puts option summary into to and returns to. Yields each line if a block is given.

to

Output destination, which must have method <<. Defaults to [].

width

Width of left side, defaults to @summary_width.

max

Maximum length allowed for left side, defaults to width - 1.

indent

Indentation, defaults to @summary_indent.

Creates an option from the given parameters params. See Parameters for New Options.

The block, if given, is the handler for the created option. When the option is encountered during command-line parsing, the block is called with the argument given for the option, if any. See Option Handlers.

Parses environment variable env or its uppercase with splitting like a shell.

env defaults to the basename of the program.

Returns the path to the data store file.

Ends the current PStore#transaction, committing any changes to the data store immediately.

Example:

require "pstore"

store = PStore.new("data_file.pstore")
store.transaction do  # begin transaction
  # load some data into the store...
  store[:one] = 1
  store[:two] = 2

  store.commit        # end transaction here, committing changes

  store[:three] = 3   # this change is never reached
end

WARNING: This method is only valid in a PStore#transaction. It will raise PStore::Error if called at any other time.

Ends the current PStore#transaction, discarding any changes to the data store.

Example:

require "pstore"

store = PStore.new("data_file.pstore")
store.transaction do  # begin transaction
  store[:one] = 1     # this change is not applied, see below...
  store[:two] = 2     # this change is not applied, see below...

  store.abort         # end transaction here, discard all changes

  store[:three] = 3   # this change is never reached
end

WARNING: This method is only valid in a PStore#transaction. It will raise PStore::Error if called at any other time.

Returns the full path name of the temporary file. This will be nil if unlink has been called.

The reason this block was terminated: :break, :redo, :retry, :next, :return, or :noreason.

Returns a clone of this method.

class A
  def foo
    return "bar"
  end
end

m = A.new.method(:foo)
m.call # => "bar"
n = m.clone.call # => "bar"

Returns a clone of this method.

class A
  def foo
    return "bar"
  end
end

m = A.new.method(:foo)
m.call # => "bar"
n = m.clone.call # => "bar"

Checks if the object is shareable by ractors.

Ractor.shareable?(1)            #=> true -- numbers and other immutable basic values are frozen
Ractor.shareable?('foo')        #=> false, unless the string is frozen due to # freeze_string_literals: true
Ractor.shareable?('foo'.freeze) #=> true

See also the “Shareable and unshareable objects” section in the Ractor class docs.

Terminates the currently running thread and schedules another thread to be run.

If this thread is already marked to be killed, ::exit returns the Thread.

If this is the main thread, or the last thread, exit the process.

Give the thread scheduler a hint to pass execution to another thread. A running thread may or may not switch, it depends on OS and processor.

Terminates thr and schedules another thread to be run, returning the terminated Thread. If this is the main thread, or the last thread, exits the process.

Path of the file being run

If object is string-like, parse the string and return the parsed result as a Ruby data structure. Otherwise, generate a JSON text from the Ruby data structure object and return it.

The opts argument is passed through to generate/parse respectively. See generate and parse for their documentation.

Creates a new Pathname object from the given string, path, and returns pathname object.

In order to use this constructor, you must first require the Pathname standard library extension.

require 'pathname'
Pathname("/home/zzak")
#=> #<Pathname:/home/zzak>

See also Pathname::new for more information.

Produces a shallow copy of obj—the instance variables of obj are copied, but not the objects they reference. clone copies the frozen value state of obj, unless the :freeze keyword argument is given with a false or true value. See also the discussion under Object#dup.

class Klass
   attr_accessor :str
end
s1 = Klass.new      #=> #<Klass:0x401b3a38>
s1.str = "Hello"    #=> "Hello"
s2 = s1.clone       #=> #<Klass:0x401b3998 @str="Hello">
s2.str[1,4] = "i"   #=> "i"
s1.inspect          #=> "#<Klass:0x401b3a38 @str=\"Hi\">"
s2.inspect          #=> "#<Klass:0x401b3998 @str=\"Hi\">"

This method may have class-specific behavior. If so, that behavior will be documented under the #initialize_copy method of the class.

Returns arg as an Array.

First tries to call to_ary on arg, then to_a. If arg does not respond to to_ary or to_a, returns an Array of length 1 containing arg.

If to_ary or to_a returns something other than an Array, raises a TypeError.

Array(["a", "b"])  #=> ["a", "b"]
Array(1..5)        #=> [1, 2, 3, 4, 5]
Array(key: :value) #=> [[:key, :value]]
Array(nil)         #=> []
Array(1)           #=> [1]
