Results for: "remove_const"

Returns true iff there is more data in the string. See eos?. This method is obsolete; use eos? instead.

s = StringScanner.new('test string')
s.eos?              # These two
s.rest?             # are opposites.

Returns the “rest” of the string (i.e. everything after the scan pointer). If there is no more data (eos? = true), it returns "".

s.restsize is equivalent to s.rest_size. This method is obsolete; use rest_size instead.

Returns the type library version.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
puts tlib.version #-> "1.3"

Element Assignment

Associates the value given by value with the key given by key.

h = { "a" => 100, "b" => 200 }
h["a"] = 9
h["c"] = 4
h   #=> {"a"=>9, "b"=>200, "c"=>4}
h.store("d", 42) #=> 42
h   #=> {"a"=>9, "b"=>200, "c"=>4, "d"=>42}

key should not have its value changed while it is in use as a key (an unfrozen String passed as a key will be duplicated and frozen).

a = "a"
b = "b".freeze
h = { a => 100, b => 200 }
h.key(100).equal? a #=> false
h.key(200).equal? b #=> true

ENV.store is an alias for ENV.[]=.

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.

    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:

    # 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:

    # 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:

    # 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 revision information for the erb.rb module.

Version

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

Executes command… in a subshell. command… is one of following forms.

commandline

command line string which is passed to the standard shell

cmdname, arg1, ...

command name and one or more arguments (no shell)

[cmdname, argv0], arg1, ...

command name, argv[0] and zero or more arguments (no shell)

system returns true if the command gives zero exit status, false for non zero exit status. Returns nil if command execution fails. An error status is available in $?.

If the exception: true argument is passed, the method raises an exception instead of returning false or nil.

The arguments are processed in the same way as for Kernel#spawn.

The hash arguments, env and options, are same as exec and spawn. See Kernel#spawn for details.

system("echo *")
system("echo", "*")

produces:

config.h main.rb
*

Error handling:

system("cat nonexistent.txt")
# => false
system("catt nonexistent.txt")
# => nil

system("cat nonexistent.txt", exception: true)
# RuntimeError (Command failed with exit 1: cat)
system("catt nonexistent.txt", exception: true)
# Errno::ENOENT (No such file or directory - catt)

See Kernel#exec for the standard shell.

Returns current status of GC stress mode.

Updates the GC stress mode.

When stress mode is enabled, the GC is invoked at every GC opportunity: all memory and object allocations.

Enabling stress mode will degrade performance, it is only for debugging.

flag can be true, false, or an integer bit-ORed following flags.

0x01:: no major GC
0x02:: no immediate sweep
0x04:: full mark after malloc/calloc/realloc

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.

Returns an Array of SingleResponse for this BasicResponse.

Restore session state from the session’s FileStore file.

Returns the session state as a hash.

Restore session state.

Returns session data as a hash.

Restore (empty) session state.

Restore session state from the session’s PStore file.

Returns the session state as a hash.
