feature request: zip

[lowks]

There is this:

https://github.com/brimworks/lua-zip

Can we consider integrating it's functions into Penlight so that we can possibly do something like:

> dir.getdirectories('/home/lowks').zip('all_directories.zip')

or

> dir.getfiles('/home/lowks').zip('all_directories.zip')

Zipping is a common operation, but I feel it's outside the scope of PL - after all, PL doesn't do sockets (although it does do simple XML, which is an exception).

Rather than introducing a new dependency here, I'd go for wrapping the underlying command (zip, 7z, whatever). That should work well enough!

Okay that will do too :)
