[Pharo-project] Generators for Pharo Xmax wish)
I earlier posted a Xmas wish that Pharo add generators (steal the generators code from Squeak). No one appeared to be familiar with them. The generators code was added to Squeak by Andreas Raas. The class Generator can be found in Squeak as a subclass of Stream. It's about 140 lines of code and, as I said before, is really useful and needed in order for me to port some of the packages I am developing from Squeak to Pharo. Class Generator is tested in class GeneratorTest which also serves as examples of uses of Generators. So please, someone go steal the code! And stealing is easy. For example I stole the following comment on class Generator directly from the class comment: " A Generator transforms callback interfaces into stream interfaces. When a producer algorithm provide results as callbacks (blocks) and a consumer algorithm expects streamable input, a Generator transforms one into the other, for example: | generator | generator := Generator on: [:g| Integer primesUpTo: 100 do:[:prime| g yield: prime]]. [generator atEnd] whileFalse:[Transcript show: generator next]. " Regards, Ralph Boland
The easiest way to get this code into pharo core is to create a mcz package, put it on PharoInbox on squeaksource and create a ticket in code.google.com/p/pharo referencing it and taggint it Fixed, this way Stéphane or Markus can harvest it to the core image. If the mcz package is overkill, then a simple fileout of the package in squeak attached to the ticket will do. Maybe in the long term a project on squeaksource should be created (if not exists) and new changes to to it and from there pulled to squeak and pharo.

Hi, Before integrating some code into Pharo the first step is to check that the licence is MIT. Noury On 5 janv. 2011, at 00:22, Miguel Cobá wrote:

from Squeak it is since they publish in MIT. Having tests and class comments would be a good check.

Ralph please package it, open ticket, so that we have tracability.
And stealing is easy.
We are not stealing we are reusing. And Generator are probably coming from GNU Smalltalk.
