Returns Regexp that is default self.regexp[:ABS_URI_REF], unless schemes is provided. Then it is a Regexp.union with self.pattern[:X_ABS_URI].
Constructs the default Hash of Regexp’s.
Converts the contents of the database to an in-memory Hash object, and returns it.
Invoked by IO#read or IO#Buffer.read to read length bytes from io into a specified buffer (see IO::Buffer) at the given offset.
The length argument is the “minimum length to be read”. If the IO buffer size is 8KiB, but the length is 1024 (1KiB), up to 8KiB might be read, but at least 1KiB will be. Generally, the only case where less data than length will be read is if there is an error reading the data.
Specifying a length of 0 is valid and means try reading at least once and return any available data.
Suggested implementation should try to read from io in a non-blocking manner and call io_wait if the io is not ready (which will yield control to other fibers).
See IO::Buffer for an interface available to return data.
Expected to return number of bytes read, or, in case of an error, -errno (negated number corresponding to system’s error code).
The method should be considered experimental.
Invoked by IO#pread or IO::Buffer#pread to read length bytes from io at offset from into a specified buffer (see IO::Buffer) at the given offset.
This method is semantically the same as io_read, but it allows to specify the offset to read from and is often better for asynchronous IO on the same file.
The method should be considered experimental.
Returns the destination encoding as an encoding object.
Returns the one-character string which cause Encoding::UndefinedConversionError.
ec = Encoding::Converter.new("ISO-8859-1", "EUC-JP") begin ec.convert("\xa0") rescue Encoding::UndefinedConversionError puts $!.error_char.dump #=> "\xC2\xA0" p $!.error_char.encoding #=> #<Encoding:UTF-8> end
Returns the destination encoding as an encoding object.
Returns the discarded bytes when Encoding::InvalidByteSequenceError occurs.
ec = Encoding::Converter.new("EUC-JP", "ISO-8859-1") begin ec.convert("abc\xA1\xFFdef") rescue Encoding::InvalidByteSequenceError p $! #=> #<Encoding::InvalidByteSequenceError: "\xA1" followed by "\xFF" on EUC-JP> puts $!.error_bytes.dump #=> "\xA1" puts $!.readagain_bytes.dump #=> "\xFF" end
Returns the bytes to be read again when Encoding::InvalidByteSequenceError occurs.
Returns the destination encoding as an Encoding object.
Returns the length of the hash value of the digest.
This method should be overridden by each implementation subclass. If not, digest_obj.digest().length() is returned.
Parses a C prototype signature
If Hash tymap is provided, the return value and the arguments from the signature are expected to be keys, and the value will be the C type to be looked up.
Example:
require 'fiddle/import' include Fiddle::CParser #=> Object parse_signature('double sum(double, double)') #=> ["sum", Fiddle::TYPE_DOUBLE, [Fiddle::TYPE_DOUBLE, Fiddle::TYPE_DOUBLE]] parse_signature('void update(void (*cb)(int code))') #=> ["update", Fiddle::TYPE_VOID, [Fiddle::TYPE_VOIDP]] parse_signature('char (*getbuffer(void))[80]') #=> ["getbuffer", Fiddle::TYPE_VOIDP, []]
Creates a class to wrap the C struct with the value ty
See also Fiddle::Importer.struct
Returns a new instance of the C struct with the value ty at the addr address.
Returns a new Fiddle::Pointer instance at the memory address of the given name symbol.
Raises a DLError if the name doesn’t exist.
Returns a new Fiddle::Function instance at the memory address of the given name function.
Raises a DLError if the name doesn’t exist.
argtype is an Array of arguments, passed to the name function.
ctype is the return type of the function
call_type is the ABI of the function
See also Fiddle:Function.new
See Fiddle::CompositeHandler.sym and Fiddle::Handler.sym
Reads at most maxlen bytes in the non-blocking manner.
When no data can be read without blocking it raises OpenSSL::SSL::SSLError extended by IO::WaitReadable or IO::WaitWritable.
IO::WaitReadable means SSL needs to read internally so read_nonblock should be called again when the underlying IO is readable.
IO::WaitWritable means SSL needs to write internally so read_nonblock should be called again after the underlying IO is writable.
OpenSSL::Buffering#read_nonblock needs two rescue clause as follows:
# emulates blocking read (readpartial). begin result = ssl.read_nonblock(maxlen) rescue IO::WaitReadable IO.select([io]) retry rescue IO::WaitWritable IO.select(nil, [io]) retry end
Note that one reason that read_nonblock writes to the underlying IO is when the peer requests a new TLS/SSL handshake. See openssl the FAQ for more details. www.openssl.org/support/faq.html
By specifying a keyword argument exception to false, you can indicate that read_nonblock should not raise an IO::Wait*able exception, but return the symbol :wait_writable or :wait_readable instead. At EOF, it will return nil instead of raising EOFError.
Parses multipart form elements according to
http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4.2
Returns a hash of multipart form parameters with bodies of type StringIO or Tempfile depending on whether the multipart form element exceeds 10 KB
params[name => body]
Generate an Image Button Input element as a string.
src is the URL of the image to use for the button. name is the input name. alt is the alternative text for the image.
Alternatively, the attributes can be specified as a hash.
image_button("url") # <INPUT TYPE="image" SRC="url"> image_button("url", "name", "string") # <INPUT TYPE="image" SRC="url" NAME="name" ALT="string"> image_button("SRC" => "url", "ALT" => "string") # <INPUT TYPE="image" SRC="url" ALT="string">
Generate a Form element with multipart encoding as a String.
Multipart encoding is used for forms that include file uploads.
action is the action to perform. enctype is the encoding type, which defaults to “multipart/form-data”.
Alternatively, the attributes can be specified as a hash.
multipart_form{ "string" } # <FORM METHOD="post" ENCTYPE="multipart/form-data">string</FORM> multipart_form("url") { "string" } # <FORM METHOD="post" ACTION="url" ENCTYPE="multipart/form-data">string</FORM>
Generate a Password Input element as a string.
name is the name of the input field. value is its default value. size is the size of the input field display. maxlength is the maximum length of the inputted password.
Alternatively, attributes can be specified as a hash.
password_field("name") # <INPUT TYPE="password" NAME="name" SIZE="40"> password_field("name", "value") # <INPUT TYPE="password" NAME="name" VALUE="value" SIZE="40"> password_field("password", "value", 80, 200) # <INPUT TYPE="password" NAME="name" VALUE="value" SIZE="80" MAXLENGTH="200"> password_field("NAME" => "name", "VALUE" => "value") # <INPUT TYPE="password" NAME="name" VALUE="value">
