   # => "'Stop!'+said Fred"

Reads a one-character string from the stream. Raises an EOFError at end of file.

Writes s to the stream. If the argument is not a String it will be converted using .to_s method. Returns the number of bytes written.

See IO#write

Generate a submit button Input element, as a String.

value is the text to display on the button. name is the name of the input.

Alternatively, the attributes can be specified as a hash.

submit
  # <INPUT TYPE="submit">

submit("ok")
  # <INPUT TYPE="submit" VALUE="ok">

submit("ok", "button1")
  # <INPUT TYPE="submit" VALUE="ok" NAME="button1">

submit("VALUE" => "ok", "NAME" => "button1", "ID" => "foo")
  # <INPUT TYPE="submit" VALUE="ok" NAME="button1" ID="foo">

Generate a TextArea element, as a String.

name is the name of the textarea. cols is the number of columns and rows is the number of rows in the display.

Alternatively, the attributes can be specified as a hash.

The body is provided by the passed-in no-argument block

textarea("name")
   # = textarea("NAME" => "name", "COLS" => 70, "ROWS" => 10)

textarea("name", 40, 5)
   # = textarea("NAME" => "name", "COLS" => 40, "ROWS" => 5)

returns a charset parameter in Content-Type field. It is downcased for canonicalization.

If charset parameter is not given but a block is given, the block is called and its result is returned. It can be used to guess charset.

If charset parameter and block is not given, nil is returned except text type. In that case, “utf-8” is returned as defined by RFC6838 4.2.1

Writes pemmable, which must respond to to_pem to path with the given permissions. If passed cipher and passphrase those arguments will be passed to to_pem.

Displays an alert statement. Asks a question if given.

Switch the effective and real user IDs of the current process. If a block is given, the user IDs will be switched back after the block is executed. Returns the new effective user ID if called without a block, and the return value of the block if one is given.

Switch the effective and real group IDs of the current process. If a block is given, the group IDs will be switched back after the block is executed. Returns the new effective group ID if called without a block, and the return value of the block if one is given.
