Returns an integer representing the numeric file descriptor for ios.
$stdin.fileno #=> 0 $stdout.fileno #=> 1
Returns the number of key-value pairs in this database.
Removes the key-value-pair with the specified key from this database and returns the corresponding value. Returns nil if the database is empty.
Removes all the key-value pairs within gdbm.
Alias for Regexp.new
Removes all elements and returns self.
set = Set[1, 'c', :s] #=> #<Set: {1, "c", :s}> set.clear #=> #<Set: {}> set #=> #<Set: {}>
Deletes the given object from the set and returns self. Use subtract to delete many items at once.
Deletes the given object from the set and returns self. If the object is not in the set, returns nil.
Same as sym.to_s.length.
Returns clean pathname of self with consecutive slashes and useless dots removed. The filesystem is not accessed.
If consider_symlink is true, then a more conservative algorithm is used to avoid breaking symbolic linkages. This may retain more .. entries than absolutely necessary, but without accessing the filesystem, this can’t be avoided.
See Pathname#realpath.
Removes a file or directory, using File.unlink if self is a file, or Dir.unlink as necessary.
Tokenizes the Ruby program and returns an array of an array, which is formatted like [[lineno, column], type, token, state]. The filename argument is mostly ignored. By default, this method does not handle syntax errors in src, use the raise_errors keyword to raise a SyntaxError for an error in src.

By overriding Object#methods, WIN32OLE might work well with did_you_mean gem. This is experimental.
require 'win32ole' dict = WIN32OLE.new('Scripting.Dictionary') dict.Ade('a', 1) #=> Did you mean? Add
Sets current codepage. The WIN32OLE.codepage is initialized according to Encoding.default_internal. If Encoding.default_internal is nil then WIN32OLE.codepage is initialized according to Encoding.default_external.
WIN32OLE.codepage = WIN32OLE::CP_UTF8 WIN32OLE.codepage = 65001
Returns current locale id (lcid). The default locale is WIN32OLE::LOCALE_SYSTEM_DEFAULT.
lcid = WIN32OLE.locale
