Replaces self by other URI object.
v
Public setter for the scheme component v (with validation).
See also URI::Generic.check_scheme.
require 'uri' uri = URI.parse("http://my.example.com") uri.scheme = "https" uri.to_s #=> "https://my.example.com"
Converts the contents of the database to an in-memory Hash, then calls Hash#reject with the specified code block, returning a new Hash.
Returns a Hash (not a DBM database) created by using each value in the database as a key, with the corresponding key as its value.
Note that all values in the hash will be Strings, but the keys will be actual objects.
Replaces the contents of the database with the contents of the specified object. Takes any object which implements the each_pair method, including Hash and DBM objects.
Returns true if the queue is empty.
Returns true if the queue is empty.
Escape only the tags of certain HTML elements in string.
Takes an element or elements or array of elements. Each element is specified by the name of the element, without angle brackets. This matches both the start and the end tag of that element. The attribute list of the open tag will also be escaped (for instance, the double-quotes surrounding attribute values).
print CGI.escapeElement('<BR><A HREF="url"></A>', "A", "IMG") # "<BR><A HREF="url"></A>" print CGI.escapeElement('<BR><A HREF="url"></A>', ["A", "IMG"]) # "<BR><A HREF="url"></A>"
Undo escaping such as that done by CGI.escapeElement()
print CGI.unescapeElement( CGI.escapeHTML('<BR><A HREF="url"></A>'), "A", "IMG") # "<BR><A HREF="url"></A>" print CGI.unescapeElement( CGI.escapeHTML('<BR><A HREF="url"></A>'), ["A", "IMG"]) # "<BR><A HREF="url"></A>"
Prettify (indent) an HTML string.
string is the HTML string to indent. shift is the indentation unit to use; it defaults to two spaces.
print CGI.pretty("<HTML><BODY></BODY></HTML>") # <HTML> # <BODY> # </BODY> # </HTML> print CGI.pretty("<HTML><BODY></BODY></HTML>", "\t") # <HTML> # <BODY> # </BODY> # </HTML>
Resets the digest to the initial state and returns self.
This method is overridden by each implementation subclass.
Construct a new class given a C:
class klass (CUnion, CStruct, or other that provide an entity_class)
types (Fiddle::TYPE_INT, Fiddle::TYPE_SIZE_T, etc., see the C types constants)
corresponding members
Fiddle::Importer#struct and Fiddle::Importer#union wrap this functionality in an easy-to-use manner.
Examples:
require 'fiddle/struct' require 'fiddle/cparser' include Fiddle::CParser types, members = parse_struct_signature(['int i','char c']) MyStruct = Fiddle::CStructBuilder.create(Fiddle::CUnion, types, members) MyStruct.malloc(Fiddle::RUBY_FREE) do |obj| ... end obj = MyStruct.malloc(Fiddle::RUBY_FREE) begin ... ensure obj.call_free end obj = MyStruct.malloc begin ... ensure Fiddle.free obj.to_ptr end

Like getc, but raises an exception if already at end-of-stream; see Character IO.
Like getbyte, but raises an exception if already at end-of-stream; see Byte IO.
Similar to read, but raises EOFError at end of string instead of returning nil, as well as IO#sysread does.

Reads size bytes from the stream. If buf is provided it must reference a string which will receive the data.
See IO#read for full details.
Reads at most maxlen bytes from the stream. If buf is provided it must reference a string which will receive the data.
See IO#readpartial for full details.
Reads a line from the stream which is separated by eol.
Raises EOFError if at end of file.
Reads a one-character string from the stream. Raises an EOFError at end of file.
Reads a DER or PEM encoded string from string or io and returns an instance of the appropriate PKey class.
string is a DER- or PEM-encoded string containing an arbitrary private or public key.
io is an instance of IO containing a DER- or PEM-encoded arbitrary private or public key.
pwd is an optional password in case string or io is an encrypted PEM resource.
