This is an MPQ decoder compatible with MPQ v1 and v2. Support for later versions will be added over time.

Usage

Start by opening an Archive with mpq.Open():

// open an Archive
archive, err := mpq.Open("sample/test.SC2Replay")
// handle err

Now you can read files like this:

// File implements io.ReadCloser
file, err := archive.Open("Path\\to\\file")
// handle err

// read all bytes from File
file_bytes, err := io.ReadAll(file)
// handle err

// close 
err = file.Close()
// handle err

You can make use of the listfile that most MPQs contain with the List() method:

list, err := archive.List()
// handle err

for list.Next() {
    fmt.Println(list.Path())
}

list.Close()

You can also load multiple Archives on top of eachother, using the mpq.Set structure.

set, err := mpq.GlobSet(
    "common.MPQ",
    "*/locale-*.MPQ",
    "*/speech-*.MPQ")
// handle err

// Open a file from a Set, favoring the highest-order Archives
file, err := set.Open("Path\\to\\file")

// List files from a Set
list, err := set.List()
