An easy to use Zip file compress/uncompress library for ASL. It is based on the miniz library. It might be merged into the ASL library in the future. Zip archives and inserted files can have Unicode names in UTF-8, even on Windows.

You can read a specific contained file as a string or as a binary blob. Or you can extract it to a given directory (asl namespace omitted here):

ZipFile zip("archive.zip");

String text = zip["some/file.txt"].text();

zip["some/data.csv"].extract("./");  // will produce "./data.csv"

Adding files to a new zip archive can also use files, strings or byte arrays as input:

ZipFile zip("archive.zip");

zip.add("package.json", Json::encode(info));

zip.add("images/", File("some/logo.png"));  // the zip entry will be "images/logo.png"

And you can pack or unpack directories recursively with all their content:

ZipFile("archive.zip").unpack("data/desdir");

ZipFile("archive2.zip").pack("some/dir", true);

The second case will pack the contents of directory "some/dir" into "archive2.zip". The optional true argument makes the directory name "dir" be placed at the root of the zip file.

You can also enumerate the contents of a zip archive:

for(auto& item : zip.items())
{
	printf("%s %i %s\n", *item.name(), item.size(), *item.lastModified().toString());
	
	// item.text() extracts the text content
	// item.content() extracts the binary content
}
