#gobzip
package gobzip uses cgo to wrap the bzlip to provide bzip compressor in golang. Because golang native library only provides bzip uncompressor (see http://golang.org/pkg/compress/bzip2/, they have a feature request for implementing bzip compressor, but haven't finished it yet. see the issue ticker here: https://code.google.com/p/go/issues/detail?id=4828). Thus BzipWriter is introduced.
####bzlib:
- make sure you have bzlib.h, if not, please build the source code from http://www.bzip.org
- we pushed built-in Darwin/Linux amd64 lib in bzip/lib. You can use them directly if you are one of them. add them into cgo NOTE: the part and the platform you used
export CGO_CFLAGS=-Ibzip/include
export CGO_LDFLAGS=-Lbzip/Darwin_amd64/lib/
import
go get github.com/hsinhoyeh/gobzip
example
import (
"github.com/hsihoyeh/gobzip"
)
func main(){
buf := &bytes.Buffer{}
w, _ := NewBzipWriter(cBuf)
w.Write([]byte("I am a plain text message"))
w.Close()
fmt.Println(buf.Bytes())
}
