--- !ruby/object:RI::MethodDescription aliases: [] block_params: comment: - !ruby/struct:SM::Flow::P body: Packs the contents of arr into a binary sequence according to the directives in aTemplateString (see the table below) Directives ``A,'' ``a,'' and ``Z'' may be followed by a count, which gives the width of the resulting field. The remaining directives also may take a count, indicating the number of array elements to convert. If the count is an asterisk (``*''), all remaining array elements will be converted. Any of the directives ``sSiIlL'' may be followed by an underscore (``_'') to use the underlying platform's native size for the specified type; otherwise, they use a platform-independent size. Spaces are ignored in the template string. See also String#unpack. - !ruby/struct:SM::Flow::VERB body: " a = [ "a", "b", "c" ]\n n = [ 65, 66, 67 ]\n a.pack("A3A3A3") #=> "a b c "\n a.pack("a3a3a3") #=> "a\\000\\000b\\000\\000c\\000\\000"\n n.pack("ccc") #=> "ABC"\n" - !ruby/struct:SM::Flow::P body: Directives for pack. - !ruby/struct:SM::Flow::VERB body: " Directive Meaning\n ---------------------------------------------------------------\n @ | Moves to absolute position\n A | ASCII string (space padded, count is width)\n a | ASCII string (null padded, count is width)\n B | Bit string (descending bit order)\n b | Bit string (ascending bit order)\n C | Unsigned char\n c | Char\n D, d | Double-precision float, native format\n E | Double-precision float, little-endian byte order\n e | Single-precision float, little-endian byte order\n F, f | Single-precision float, native format\n G | Double-precision float, network (big-endian) byte order\n g | Single-precision float, network (big-endian) byte order\n H | Hex string (high nibble first)\n h | Hex string (low nibble first)\n I | Unsigned integer\n i | Integer\n L | Unsigned long\n l | Long\n M | Quoted printable, MIME encoding (see RFC2045)\n m | Base64 encoded string\n N | Long, network (big-endian) byte order\n n | Short, network (big-endian) byte-order\n P | Pointer to a structure (fixed-length string)\n p | Pointer to a null-terminated string\n Q, q | 64-bit number\n S | Unsigned short\n s | Short\n U | UTF-8\n u | UU-encoded string\n V | Long, little-endian byte order\n v | Short, little-endian byte order\n w | BER-compressed integer\\fnm\n X | Back up a byte\n x | Null byte\n Z | Same as ``a'', except that null is added with *\n" full_name: Array#pack is_singleton: false name: pack params: | arr.pack ( aTemplateString ) -> aBinaryString visibility: public
