Returns a string representation of lex_state.
Returns true for IPv6 multicast node-local scope address. It returns false otherwise.
Displays helpfile. The 1st argument specifies WIN32OLE_TYPE object or WIN32OLE_METHOD object or helpfile.
excel = WIN32OLE.new('Excel.Application') typeobj = excel.ole_type WIN32OLE.ole_show_help(typeobj)
Returns WIN32OLE object for a specific dispatch or dual interface specified by iid.
ie = WIN32OLE.new('InternetExplorer.Application') ie_web_app = ie.ole_query_interface('{0002DF05-0000-0000-C000-000000000046}') # => WIN32OLE object for dispinterface IWebBrowserApp
Returns WIN32OLE_TYPE object.
excel = WIN32OLE.new('Excel.Application') tobj = excel.ole_type
Returns detail information of type of argument.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'IWorksheetFunction') method = WIN32OLE_METHOD.new(tobj, 'SumIf') param1 = method.params[0] p param1.ole_type_detail # => ["PTR", "USERDEFINED", "Range"]
Returns the array of WIN32OLE_TYPE object which is implemented by the WIN32OLE_TYPE object and having IMPLTYPEFLAG_FSOURCE.
tobj = WIN32OLE_TYPE.new('Microsoft Internet Controls', "InternetExplorer") p tobj.source_ole_types # => [#<WIN32OLE_TYPE:DWebBrowserEvents2>, #<WIN32OLE_TYPE:DWebBrowserEvents>]
Returns the array of WIN32OLE_TYPE object which is implemented by the WIN32OLE_TYPE object and having IMPLTYPEFLAG_FSOURCE and IMPLTYPEFLAG_FDEFAULT.
tobj = WIN32OLE_TYPE.new('Microsoft Internet Controls', "InternetExplorer") p tobj.default_event_sources # => [#<WIN32OLE_TYPE:DWebBrowserEvents2>]
Returns detail information of type. The information is array of type.
tobj = WIN32OLE_TYPE.new('DirectX 7 for Visual Basic Type Library', 'D3DCLIPSTATUS') variable = tobj.variables.find {|variable| variable.name == 'lFlags'} tdetail = variable.ole_type_detail p tdetail # => ["USERDEFINED", "CONST_D3DCLIPSTATUSFLAGS"]
Render a template on a new toplevel binding with local variables specified by a Hash object.
Returns the value of the local variable symbol.
def foo a = 1 binding.local_variable_get(:a) #=> 1 binding.local_variable_get(:b) #=> NameError end
This method is the short version of the following code:
binding.eval("#{symbol}")
Set local variable named symbol as obj.
def foo a = 1 bind = binding bind.local_variable_set(:a, 2) # set existing local variable `a' bind.local_variable_set(:b, 3) # create new local variable `b' # `b' exists only in binding p bind.local_variable_get(:a) #=> 2 p bind.local_variable_get(:b) #=> 3 p a #=> 2 p b #=> NameError end
This method behaves similarly to the following code:
binding.eval("#{symbol} = #{obj}")
if obj can be dumped in Ruby code.
Returns true if a local variable symbol exists.
def foo a = 1 binding.local_variable_defined?(:a) #=> true binding.local_variable_defined?(:b) #=> false end
This method is the short version of the following code:
binding.eval("defined?(#{symbol}) == 'local-variable'")
Breaks the buffer into lines that are shorter than maxwidth
Returns the value of a thread local variable that has been set. Note that these are different than fiber local values. For fiber local values, please see Thread#[] and Thread#[]=.
Thread local values are carried along with threads, and do not respect fibers. For example:
Thread.new { Thread.current.thread_variable_set("foo", "bar") # set a thread local Thread.current["foo"] = "bar" # set a fiber local Fiber.new { Fiber.yield [ Thread.current.thread_variable_get("foo"), # get the thread local Thread.current["foo"], # get the fiber local ] }.resume }.join.value # => ['bar', nil]
The value “bar” is returned for the thread local, where nil is returned for the fiber local. The fiber is executed in the same thread, so the thread local values are available.
Sets a thread local with key to value. Note that these are local to threads, and not to fibers. Please see Thread#thread_variable_get and Thread#[] for more information.
For debugging the Ruby/OpenSSL library. Calls CRYPTO_mem_leaks_fp(stderr). Prints detected memory leaks to standard error. This cleans the global state up thus you cannot use any methods of the library after calling this.
Returns true if leaks detected, false otherwise.
This is available only when built with a capable OpenSSL and –enable-debug configure option.
OpenSSL.mem_check_start NOT_GCED = OpenSSL::PKey::RSA.new(256) END { GC.start OpenSSL.print_mem_leaks # will print the leakage }
Safely loads the document contained in filename. Returns the yaml contained in filename as a Ruby object, or if the file is empty, it returns the specified fallback return value, which defaults to false. See safe_load for options.
This method removes a file system entry path. path shall be a regular file, a directory, or something. If path is a directory, remove it recursively. This method is required to avoid TOCTTOU (time-of-check-to-time-of-use) local security vulnerability of rm_r. rm_r causes security hole when:
Parent directory is world writable (including /tmp).
Removing directory tree includes world writable directory.
The system has symbolic link.
To avoid this security hole, this method applies special preprocess. If path is a directory, this method chown(2) and chmod(2) all removing directories. This requires the current process is the owner of the removing whole directory tree, or is the super user (root).
WARNING: You must ensure that ALL parent directories cannot be moved by other untrusted users. For example, parent directories should not be owned by untrusted users, and should not be world writable except when the sticky bit set.
WARNING: Only the owner of the removing directory tree, or Unix super user (root) should invoke this method. Otherwise this method does not work.
For details of this security vulnerability, see Perl’s case:
For fileutils.rb, this vulnerability is reported in [ruby-dev:26100].

Decodes URL-encoded form data from given str.
This decodes application/x-www-form-urlencoded data and returns an array of key-value arrays.
This refers url.spec.whatwg.org/#concept-urlencoded-parser, so this supports only &-separator, and doesn’t support ;-separator.
ary = URI.decode_www_form("a=1&a=2&b=3") ary #=> [['a', '1'], ['a', '2'], ['b', '3']] ary.assoc('a').last #=> '1' ary.assoc('b').last #=> '3' ary.rassoc('a').last #=> '2' Hash[ary] #=> {"a"=>"2", "b"=>"3"}
