Package for providing a way to show readable values of byte sizes by reediting the code from http://golang.org/doc/effective_go.html. It could also parsing byte size text to ByteSize object.
This package is "go-gettable", just:
go get github.com/shenwei356/util/bytesize
fmt.Printf("1024 bytes\t%v\n", bytesize.ByteSize(1024))
fmt.Printf("13146111 bytes\t%v\n", bytesize.ByteSize(13146111))
// parsing
size, err := bytesize.Parse([]byte("1.5 KB"))
if err != nil {
fmt.Println(err)
}
fmt.Printf("\n%.0f bytes\n", size)
Result:
1024 bytes 1.00 KB
13146111 bytes 12.54 MB
1536 bytes
(?i)^\s*([\-\d\.]+)\s*([KMGTPEZY]?B|[BKMGTPEZY]|)\s*$
Example:
data["1234.2 kb"] = 1263820.80 lower case
data["-1234.2 kb"] = -1263820.80 lower case
data[" 1234.2 kb "] = 1263820.80 space
data["1234.2 k"] = 1263820.80 simple unit
data["1234.2 "] = 1234.2 no unit
data[" kb "] = -1 illegal value
data["- kb"] = -1 illegal value
data["1234.2 aB"] = -1 illegal unit
data["1234.2 Packages"] = -1 illegal unit
