Results for: "pstore"

Associates the given value with the given key; returns value.

If the given key exists, replaces its value with the given value; the ordering is not affected (see Entry Order):

h = {foo: 0, bar: 1}
h[:foo] = 2 # => 2
h.store(:bar, 3) # => 3
h # => {:foo=>2, :bar=>3}

If key does not exist, adds the key and value; the new entry is last in the order (see Entry Order):

h = {foo: 0, bar: 1}
h[:baz] = 2 # => 2
h.store(:bat, 3) # => 3
h # => {:foo=>0, :bar=>1, :baz=>2, :bat=>3}

Creates, updates, or deletes the named environment variable, returning the value. Both name and value may be instances of String. See Valid Names and Values.

• If the named environment variable does not exist:

  • If value is nil, does nothing.

    Example

    ENV.clear
    ENV['foo'] = nil # => nil
    ENV.include?('foo') # => false
    ENV.store('bar', nil) # => nil
    ENV.include?('bar') # => false
    

  • If value is not nil, creates the environment variable with name and value:

    Example

    # Create 'foo' using ENV.[]=.
    ENV['foo'] = '0' # => '0'
    ENV['foo'] # => '0'
    # Create 'bar' using ENV.store.
    ENV.store('bar', '1') # => '1'
    ENV['bar'] # => '1'
    

• If the named environment variable exists:

  • If value is not nil, updates the environment variable with value value:

    Example

    # Update 'foo' using ENV.[]=.
    ENV['foo'] = '2' # => '2'
    ENV['foo'] # => '2'
    # Update 'bar' using ENV.store.
    ENV.store('bar', '3') # => '3'
    ENV['bar'] # => '3'
    

  • If value is nil, deletes the environment variable:

    Example

    # Delete 'foo' using ENV.[]=.
    ENV['foo'] = nil # => nil
    ENV.include?('foo') # => false
    # Delete 'bar' using ENV.store.
    ENV.store('bar', nil) # => nil
    ENV.include?('bar') # => false
    

Raises an exception if name or value is invalid. See Invalid Names and Values.

Returns a copy of the storage hash for the fiber. The method can only be called on the Fiber.current.

Sets the storage hash for the fiber. This feature is experimental and may change in the future. The method can only be called on the Fiber.current.

You should be careful about using this method as you may inadvertently clear important fiber-storage state. You should mostly prefer to assign specific keys in the storage using Fiber::[]=.

You can also use Fiber.new(storage: nil) to create a fiber with an empty storage.

Example:

while request = request_queue.pop
  # Reset the per-request state:
  Fiber.current.storage = nil
  handle_request(request)
end

With string object given, returns true if path is a string path leading to a directory, or to a symbolic link to a directory; false otherwise:

File.directory?('.')              # => true
File.directory?('foo')            # => false
File.symlink('.', 'dirlink')      # => 0
File.directory?('dirlink')        # => true
File.symlink('t,txt', 'filelink') # => 0
File.directory?('filelink')       # => false

Argument path can be an IO object.

Returns a list of modules included/prepended in mod (including mod itself).

module Mod
  include Math
  include Comparable
  prepend Enumerable
end

Mod.ancestors        #=> [Enumerable, Mod, Comparable, Math]
Math.ancestors       #=> [Math]
Enumerable.ancestors #=> [Enumerable]

Quietly ensure the Gem directory dir contains all the proper subdirectories. If we can’t create a directory due to a permission problem, then we will silently continue.

If mode is given, missing directories are created with this mode.

World-writable directories will never be created.

Stores value in database with key as the index. value is converted to YAML before being stored.

Returns value

Arguments a and b should be interpretable as a path.
