Returns true if self contains other_string, false otherwise:
s = 'foo' s.include?('f') # => true s.include?('fo') # => true s.include?('food') # => false
Returns a left-justified copy of self.
If integer argument size is greater than the size (in characters) of self, returns a new string of length size that is a copy of self, left justified and padded on the right with pad_string:
'hello'.ljust(10) # => "hello " ' hello'.ljust(10) # => " hello " 'hello'.ljust(10, 'ab') # => "helloababa" 'тест'.ljust(10) # => "тест " 'こんにちは'.ljust(10) # => "こんにちは "
If size is not greater than the size of self, returns a copy of self:
'hello'.ljust(5) # => "hello" 'hello'.ljust(1) # => "hello"

Returns a right-justified copy of self.
If integer argument size is greater than the size (in characters) of self, returns a new string of length size that is a copy of self, right justified and padded on the left with pad_string:
'hello'.rjust(10) # => " hello" 'hello '.rjust(10) # => " hello " 'hello'.rjust(10, 'ab') # => "ababahello" 'тест'.rjust(10) # => " тест" 'こんにちは'.rjust(10) # => " こんにちは"
If size is not greater than the size of self, returns a copy of self:
'hello'.rjust(5, 'ab') # => "hello" 'hello'.rjust(1, 'ab') # => "hello"

Returns a copy of self with each character specified by string selector translated to the corresponding character in string replacements. The correspondence is positional:
Each occurrence of the first character specified by selector is translated to the first character in replacements.
Each occurrence of the second character specified by selector is translated to the second character in replacements.
And so on.
Example:
'hello'.tr('el', 'ip') #=> "hippo"
If replacements is shorter than selector, it is implicitly padded with its own last character:
'hello'.tr('aeiou', '-') # => "h-ll-" 'hello'.tr('aeiou', 'AA-') # => "hAll-"
Arguments selector and replacements must be valid character selectors (see Character Selectors), and may use any of its valid forms, including negation, ranges, and escaping:
# Negation. 'hello'.tr('^aeiou', '-') # => "-e--o" # Ranges. 'ibm'.tr('b-z', 'a-z') # => "hal" # Escapes. 'hel^lo'.tr('\^aeiou', '-') # => "h-l-l-" # Escaped leading caret. 'i-b-m'.tr('b\-z', 'a-z') # => "ibabm" # Escaped embedded hyphen. 'foo\\bar'.tr('ab\\', 'XYZ') # => "fooZYXr" # Escaped backslash.
Like String#tr, but modifies self in place. Returns self if any changes were made, nil otherwise.
Get the address as an Integer for the function named name. The function is searched via dlsym on RTLD_NEXT.
See man(3) dlsym() for more info.
Get the address as an Integer for the function named name.
Get the underlying pointer for ruby object val and return it as a Fiddle::Pointer object.
Returns integer stored at index.
If start and length are given, a string containing the bytes from start of length will be returned.
Fetch struct member name if only one argument is specified. If two arguments are specified, the first is an offset and the second is a length and this method returns the string of length bytes beginning at offset.
Examples:
my_struct = struct(['int id']).malloc my_struct.id = 1 my_struct['id'] # => 1 my_struct[0, 4] # => "\x01\x00\x00\x00".b
Gets all key-value pairs in a specific section from the current configuration.
Given the following configurating file being loaded:
config = OpenSSL::Config.load('foo.cnf') #=> #<OpenSSL::Config sections=["default"]> puts config.to_s #=> [ default ] # foo=bar
You can get a hash of the specific section like so:
config['default'] #=> {"foo"=>"bar"}
Read a registry value named name and return its value data. The class of the value is the same as the read method returns.
If the value type is REG_EXPAND_SZ, returns value data whose environment variables are replaced. If the value type is neither REG_SZ, REG_MULTI_SZ, REG_DWORD, REG_DWORD_BIG_ENDIAN, nor REG_QWORD, TypeError is raised.
The meaning of rtype is the same as for the read method.
Returns the element of WIN32OLE::Variant object(OLE array). This method is available only when the variant type of WIN32OLE::Variant object is VT_ARRAY.
REMARK:
The all indices should be 0 or natural number and lower than or equal to max indices. (This point is different with Ruby Array indices.) obj = WIN32OLE::Variant.new([[1,2,3],[4,5,6]]) p obj[0,0] # => 1 p obj[1,0] # => 4 p obj[2,0] # => WIN32OLE::RuntimeError p obj[0, -1] # => WIN32OLE::RuntimeError
Retrieve the session data for key key.
Retrieve the code units offset from the given byte offset.
Returns a Command instance for command_name
Return the configuration information for key.
Queries the configuration for the given key.
Return value associated with key from database.
Returns nil if there is no such key.
See fetch for more information.
