mpq

Package mpq is a decoder/parser of Blizzard's MPQ archive file format.

This is not a full MPQ implementation. It is primarily intended to parse StarCraft II replay files (*.SC2Replay), but that is fully supported.

Usage

Usage is simple. Opening an MPQ archive file:

m, err := mpq.NewFromFile("myreplay.SC2Replay")
if err != nil {
    // Handle error
    return
}
defer m.Close()

Getting a named file from the archive:

// Access a file inside the MPQ archive.
// Usually there is a file called "(listfile)" containing the list of other files:
if data, err := m.FileByName("(listfile)"); err == nil {
    fmt.Println("Files inside archive:")
    fmt.Println(string(data))
} else {
    // handle error
}

If you already have the MPQ data in memory:

mpqdata := []byte{} // MPQ data in memory
m, err := mpq.New(bytes.NewReader(mpqdata)))
