LZSS compression package for Go.
go get github.com/blacktop/lzssgo install github.com/blacktop/lzss/cmd@v0.1.6# Compress a file
lzss -c input.txt # creates input.txt.lzss
# Decompress a file
lzss -d input.txt.lzss # creates input.txt
# Custom output file
lzss -c -o compressed.lzss input.txt
lzss -d -o output.txt input.lzss
# Show help
lzss -himport (
"io/ioutil"
"log"
"github.com/blacktop/lzss"
"github.com/pkg/errors"
)
func main() {
// Compress data
data, err := ioutil.ReadFile("input.txt")
if err != nil {
log.Fatal(errors.Wrap(err, "failed to read input file"))
}
compressed := lzss.Compress(data)
err = ioutil.WriteFile("compressed.bin", compressed, 0644)
if err != nil {
log.Fatal(errors.Wrap(err, "failed to write compressed file"))
}
}import (
"io/ioutil"
"log"
"github.com/blacktop/lzss"
"github.com/pkg/errors"
)
func main() {
dat, err := ioutil.ReadFile("compressed.bin")
if err != nil {
log.Fatal(errors.Wrap(err, "failed to read compressed file"))
}
decompressed := lzss.Decompress(dat)
err = ioutil.WriteFile("compressed.bin.decompressed", decompressed, 0644)
if err != nil {
log.Fatal(errors.Wrap(err, "failed to decompress file"))
}
}NOTE: I believe lzss expects the data to be word aligned.
