Q: Example of how to execute IRepositoryClient.GetArchive()?

[UsgsMonkey]

Greetings,

I'm relatively new to asynchronous programming and am looking for guidance or links to proper guidance on how to code in the "Action<Stream>" argument input required by IRepositoryClient.GetArchive(). This seems to reference an async pattern and there's not documentation to lead the way. Any assistance would be a huge help as I stumble about trying to figure out the expected approach here. Ultimately, I'm trying to use NGitLab as a vehicle to download an archive (as a zip or other compressed format) to disk programmatically.

Warm Regards,

Brett

Hi @UsgsMonkey,

Although NGitLab does offer async methods, IRepositoryClient.GetArchive(Action<Stream> parser) is not async. The parser argument is used to pass in a callback to handle the tar.gz stream returned by GitLab. For instance, based on the code snippet found here you could print out the content of the archive as follows:

RepositoryClient.GetArchive(tgzStream =>
{
    using var gzip = new GZipStream(tgzStream, CompressionMode.Decompress);

    using var unzippedStream = new MemoryStream();
    gzip.CopyTo(unzippedStream);
    unzippedStream.Seek(0, SeekOrigin.Begin);

    using var reader = new TarReader(unzippedStream);

    while (reader.GetNextEntry() is TarEntry entry)
    {
        Console.WriteLine($"Entry name: {entry.Name}, entry type: {entry.EntryType}");
    }
});
