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.

Returns a string representation of self:

system("false")
$?.inspect # => "#<Process::Status: pid 1303494 exit 1>"

Returns a printable version of ec

ec = Encoding::Converter.new("iso-8859-1", "utf-8")
puts ec.inspect    #=> #<Encoding::Converter: ISO-8859-1 to UTF-8>

Finishes the converter. It returns the last part of the converted string.

ec = Encoding::Converter.new("utf-8", "iso-2022-jp")
p ec.convert("\u3042")     #=> "\e$B$\""
p ec.finish                #=> "\e(B"

Returns maximum backtrace length set by --backtrace-limit command-line option. The default is -1 which means unlimited backtraces. If the value is zero or positive, the error backtraces, produced by Exception#full_message, are abbreviated and the extra lines are replaced by ... 3 levels...

Returns true if key is a key in self, otherwise false.

Returns a new String containing informations about the map:

m = ObjectSpace::WeakKeyMap.new
m[key] = value
m.inspect # => "#<ObjectSpace::WeakKeyMap:0x00000001028dcba8 size=1>"

Finishes the digest and returns the resulting hash value.

This method is overridden by each implementation subclass and often made private, because some of those subclasses may leave internal data uninitialized. Do not call this method from outside. Use digest!() instead, which ensures that internal data be reset for security reasons.

Creates a printable version of the digest object.

Creates a global method from the given C signature using the given opts as bind parameters with the given block.

Reads lines from the stream which are separated by eol.

See also gets

Reads a line from the stream which is separated by eol.

Raises EOFError if at end of file.

Writes args to the stream.

See IO#print for full details.

Formats and writes to the stream converting parameters under control of the format string.

See Kernel#sprintf for format string details.

See IO#print.

See IO#printf.

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">

Check if gem name version version is installed.

A Zlib::Inflate#inflate wrapper

Replaces the content of self with the content of other_array; returns self:

a = [:foo, 'bar', 2]
a.replace(['foo', :bar, 3]) # => ["foo", :bar, 3]
