JUCE ZIP API....

[Lindon]

So JUCE has this:

https://docs.juce.com/master/classZipFile.html

..cant seem to see which version it arrived in, but i think pre-V6 - so we should be able to build this into HISE no?

Given we have file download now available - it would be very handy to be able to download zipped files and uncompress them.

Yeah it's been there for a long time.

@Lindon funny I’m trying to implement the api at the moment but to be honest I don’t think I’ll be able to do it.
@Christoph-Hart any chance to at least get a decompression api?

@Christoph-Hart Oh yes, it would be awesome

I played around with this class a few years back and I think there was something off about it.

But since this appears to be a popular request, I can just add a scripting wrapper and then you can check it out yourself.

I would suggest this API:

const var myArchive = FileSystem.getFolder(FileSystem.Desktop).getChildFile("master.zip");
const var target = FileSystem.getFolder(FileSystem.Desktop).getChildFile("unzipped_dir");

myArchive.extractZipArchive(target, function(obj)
{
     // this callback holds some information about the progress
});

@Christoph-Hart looks ideal....

@Christoph-Hart Awesome!
having progress info and a bool on success would be great!

[d.healey]

Excellent!

@Christoph-Hart if the target is a directory, why do you make a use of getChildFile?
Do we need to prep a sub folder within the target directory named for instance with original zip name as it is often the case with zip extractors?

Can we just extract the content somewhere in a directory with no sub folder? I imagine yes but just to be sure…

And what about overwriting?

@Christoph-Hart Any news on this side? I mean, I know codegen does not keep you that busy...

[Christoph Hart]

Just a short heads up - I've added the ability to track the progress for large files, so if your zip file contained 3 files with 1 GB each, it will execute the callback periodically with the true progress (bytes extracted / total bytes) properly and not just three times.

Somebody (I think David) requested this at some point, but it wasn't possible without hacking the JUCE code, but now I needed it myself, so...

@christoph-hart Thank you!
