buffer

Functions for the manipulation of byte slices in Ruby.

Examples

Buffer.int(20).hex# => "14"Buffer.int(20).bytes# => [20]Buffer.int(20).chars# => ["\x14"]Buffer.int(0x65).hex# => "65"Buffer.int(0x65).bytes# => [101]Buffer.int(0x65).chars# => ["e"]Buffer.int(0b1010).hex# => "0A"Buffer.int(0b1010).bytes# => [10]Buffer.int(0b1010).chars# => ["\n"]

Buffer.str('demo').hex# => "64656D6F"Buffer.str('demo').str# => "demo"Buffer.str('demo').bits# => ["01100100", "01100101", "01101101", "01101111"]Buffer.str('demo').bytes# => [100, 101, 109, 111]Buffer.str('demo').chars# => ["d", "e", "m", "o"]Buffer.str('demo').base64# => "ZGVtbw=="

Buffer.hex('0x707172').hex# => "707172"Buffer.hex('0x707172').str# => "pqr"Buffer.hex('0x707172').bits# => ["01110000", "01110001", "01110010"]Buffer.hex('0x707172').bytes# => [112, 113, 114]Buffer.hex('0x707172').chars# => ["p", "q", "r"]Buffer.hex('0x707172').base64# => "cHFy"

Buffer.bin('01111000 01100101').hex# => "7865"Buffer.bin('01111000 01100101').str# => "xe"Buffer.bin('01111000 01100101').bits# => ["01111000", "01100101"]Buffer.bin('01111000 01100101').bytes# => [120, 101]Buffer.bin('01111000 01100101').chars# => ["x", "e"]Buffer.bin('01111000 01100101').base64# => "eGU="

Buffer.hex('0x707172').length# => 3Buffer.hex('0x707172').last(2).hex# => "7172"Buffer.hex('0x707172').first(2).hex# => "7071"Buffer.str('string42').chunk(5,3).bits# => ["01101110", "01100111", "00110100"]Buffer.str('string42').each_byte{ |x| x + 1}.str# => "tusjoh53"Buffer.str('string42').each_chunk(2){ |ch| ch.hex}# => "7374", "7269", "6E67", "3432"

Create custom converter

classMyConverter < Buffer::ByteConverterdefconvert[70,50,30] + Buffer.int(input).bytesendendBuffer.create(0b001100,MyConverter).hex# => "46321E0C"
