How to create a .zip archive excluding (skipping) files that match a set of wildcarded patterns.

Chilkat Go Downloads Go Package for Windows, MacOS, Linux, Alpine Linux, Solaris

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    zip := chilkat.NewZip()

    success := zip.NewZip("test.zip")
    if success != true {
        fmt.Println(zip.LastErrorText())
        zip.DisposeZip()
        return
    }

    // Create a string array object with our set of filename patterns
    // to be excluded:
    sa := chilkat.NewStringArray()
    success = sa.Append("*.bak")
    success = sa.Append("*.tmp")

    // Tell the zip object to use these exclusions:
    zip.SetExclusions(sa)

    // Append a directory tree.  The AppendFiles does
    // not read the file contents or append them to the zip
    // object in memory.  It simply appends references
    // to the files so that when WriteZip (or WriteZipAndClose,
    // or WriteExe, etc.) is called, the files are compressed
    // and encrypted.
    recurse := true
    success = zip.AppendFiles("/temp/a/*",recurse)

    success := zip.WriteZipAndClose()
    if success != true {
        fmt.Println(zip.LastErrorText())
        zip.DisposeZip()
        sa.DisposeStringArray()
        return
    }

    fmt.Println("Zip Created!")

    zip.DisposeZip()
    sa.DisposeStringArray()
