runez's Introduction

Runez

An absolutely awful, but (probably) lossless, compression format for utf-8 text.

This was implemented as a proof of concept to an idea discussed over coffee with a friend.

See the spec for implementation details, or read the source ☺.

Build

; go build

Usage

runez [-D] [-c] [-d] < [input] > [output]

Example

Compressing some text in Macedonian:

; cat mac.txt
Моето летачко возило е полно со јагули
Моето летачко возило е полно со јагули
Моето летачко возило е полно со јагули
Моето летачко возило е полно со јагули
Моето летачко возило е полно со јагули
; wc -c mac.txt # Byte count
355 mac.txt
; ./runez < mac.txt > out.rz
; wc -c out.rz
290 out.rz
; ./runez -d < out.rz > newmac.txt
; diff mac.txt newmac.txt
;

Pass runez output through itself:

; ./runez -c < mac.txt | ./runez -d
Моето летачко возило е полно со јагули
Моето летачко возило е полно со јагули
Моето летачко возило е полно со јагули
Моето летачко возило е полно со јагули
Моето летачко возило е полно со јагули
;
