[Pharo-project] Pointer types
by Schwab,Wilhelm K Oct. 7, 2010

Oct. 7, 2010

Sig, You mentioned something that might be useful, depending on where it lives. Our ability to use underscores now leaves me thinking I really should rework some things that suffered mightily: there are some external things that are named assuming underscores, and in mixed case, they turn into an unreadable mess. Along with this, I have a large number of FFI calls that take double pointers, and I have for some time been demoralized into (or stupid enough to<g>) expressing them as void pointers to allow me to pass byte arrays into them. Is there a way that I can get FFI to recognize DOUBLEArray (which uses a ByteArray to hold its data) as something that should be acceptable for a double* call? If not FFI, how does NB handle it?

For Zinc HTTP Components I made a lot of effort to make it possible to read data from a socket stream in true streaming fashion (instead of just returning a byte array). Now, the idea was then that for example JPEGReadWriter>>#nextImage would work transparaently on that raw stream. Sadly, the code in JPEGReadWriter and friends just reads everything into an array before it starts to work ! >>>> >>>> Doing a #nextPutAll: <some byte array> should really try never to copy the array.

What's needed is to define a headless core that contains the compiler, good error reporting to standard out, the core collection and numeric libraries and file support. Then we try and load packages into it and build up a headful image. Yes we are trying that with nicolas paez and gabriel barbuto (will stop in December). And in the process we are fixing everything we can. Stef

[Pharo-project] Morphic and the Player class in Pharo
by Robert Hawley Oct. 7, 2010

Oct. 7, 2010

I understand that Pharo has Etoys taken out of it, however, 'real' Morphic requires costume-player pairs. Can we have the Player class back in, or is there an alternative mechanism to take on the role of Player (maybe I've missed it)? This would be to enable coding of scripts using Smalltalk syntax (not to be confused with the Etoys tiled scripts).
