File/Stream changes: one Integer decoder/encoder to rule them all
by Sven Van Caekenberghe May 14, 2018

May 14, 2018

Hi, After the File and Stream changes in Pharo 7, a binary read, resp. write stream from/to a file is actually a ZnBuffered(Read|Write)Stream on a BinaryFileStream. You access these using #binary(Read|Write)Stream[Do:] sent to a FileReference. As minimal streams the API of ZnBuffered(Read|Write)Stream was different from what existed before. Specifically, a number of Integer decoding/encoding methods were missing. It is probably best to add those (an alternative would be a subclass). When I looked at what was available, I thought I could improve upon the current situation. In fact, I think all existing ones can be written in terms of just one key method, one for reading and one for writing. The existing methods than become simple aliases, all while offering more functionality. (Incidentally this would be an ideal use of a Trait, can we use them again/still ?) The key method is #nextIntegerOfSize: numberOfBytes signed: signed bigEndian: bigEndian [put: value] and can be found in the latest version of Zinc-CharacterEncoding-Core with a comprehensive set of unit tests. For example, int32 ^ self nextIntegerOfSize: 4 signed: true bigEndian: true nextWord ^ self nextIntegerOfSize: 2 signed: false bigEndian: true or non-aliases ones like binaryStream nextIntegerOfSize: 3 signed: true bigEndian: false I think I nailed it, but I would love a second pair of eyes to check what I did. The same functionality could be added to ByteArray in a slight variation (with offsets), where similar integer encoding/decoding methods exist. Sven

Easy way to browse Hermes packages?
by Alistair Grant May 14, 2018

Hi Everyone, Is there an easy way to browse the contents of .hermes files (from the Pharo 7 bootstrap process)? Or at least list the packages, classes and methods defined within? Thanks! Alistair
