qoi-bf

This repo contains brainfuck programs that implement the Quite OK Image Format. A brainfuck implementation with wrapping 8-bit cells is required.

• fnl: sources of the programs
• bf: generated brainfuck programs (ready to use)

programs

• qoiview: display a QOI image in a terminal using ANSI escape sequences
• qoiview-kitty: display a QOI image in a terminal using the kitty graphics protocol
• colors-qoi: generate a test image containing all possible combinations of two color channels
• ppm-to-qoi: convert a ppm image to QOI using only QOI_OP_RGB chunks
• ppm-to-qoi2: convert a ppm image to QOI using QOI_OP_RGB and QOI_OP_DIFF chunks
• qoi-debug: print all chunks in a QOI file
• decoder: a template to write your own brainfuck programs that need a QOI decoder

building and testing the brainfuck programs

These steps are only necessary if you modified the source files in fnl or want to run tests. Requires:

• Fennel
• bfc
• ImageMagick

git clone --recursive https://github.com/dokutan/qoi-bf
cd qoi-bf
make # build bf/* from fnl/*
make build # compile bf/* with bfc
make debug # compile bf/* to lua for debugging
make test # run tests

# using the programs
./build/qoiview < example.qoi
