Golang library for both compressing and decompressing data in the PKWare Data Compression Library (DCL) compressed format, otherwise known as "explode" and "implode" which differ from PKZIP.
Based on:
blast.c in ZLIB written by Mark Adler https://github.com/madler/zlib/blob/master/contrib/blast/blast.c
implode.c Ladislav Zezula 2003 https://github.com/ladislav-zezula/StormLib/blob/master/src/pklib/implode.c
go get github.com/JoshVarga/blast
Compress ("implode") data using the PKWARE DCL "implode" method
Decompress ("explode") data that has been compressed using PKWARE DCL "implode" method
func ExampleNewWriter() {
var b bytes.Buffer
w := blast.NewWriter(&b, blast.Binary, blast.DictionarySize1024)
w.Write([]byte("AIAIAIAIAIAIA"))
w.Close()
fmt.Println(b.Bytes())
// Output: [0 4 130 36 37 143 128 127]
}
func ExampleNewReader() {
buff := []byte{0, 4, 130, 36, 37, 143, 128, 127}
b := bytes.NewReader(buff)
r, err := blast.NewReader(b)
if err != nil {
panic(err)
}
io.Copy(os.Stdout, r)
// Output: AIAIAIAIAIAIA
r.Close()
}
