Hi, thanks for the info :) Is your version for pharo 6.0 somewhere i can download it ? Steven.

Re: [Pharo-users] Trying to test Phantom / aspects in Pharo

by Steven Costiou

Hi, i've made it work with an old Pharo 3 (by importing one class from Pharo 1.6 and commenting some code). I think everything works. It would be nice to have it on latest Pharo, but i have no idea what is the effort of porting it. Also it could be interesting to change the backend and use Reflectivity instead of method wrappers. I could work a bit on it but probably not do everything. Steven.

Re: [Pharo-users] Iceberg Branching

by Evan Donahue

Hi, I think it's ok. I had accidentally gotten a 70 alpha version. Workflow seems fine on 61 and 70 stable versions. I tried to go in again and see what the error message was on the alpha version, but something else went wrong, and then I discovered that it had somehow found my actual working repository in another folder and was committing to that, and I decided to leave it alone lest it do something mischievous. Roughly, the error happened when I made a new branch, switched to it, committed changes, switched back to the other branch, and tried to view the packages tab to reload the old code. I don't recall what the error said. Evan -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Hi, A friend and i worked on phatom to make it work on actual pharo versions(at that momento was 6.0 or 6.1) and could make examples work and lot of tests to pass.

Re: [Pharo-users] How to declare a do:[] loop for a matrix to read and acces its elements?

by Photon

when I call the countNeighbours method i get an error: the block wants two arguments but I pass only one. This is probally because i want to pass x y but only really pass x wich ends up being a cell and not the index. I still have trouble thinking it trough. The indicieDo: method seems to make the matrix bigger?! I don`t quite understand it. There must be an easy way to to figure out if the suroundings are alive or not. I mean its all there what I need and in my mind its so easy to discribe it with normal words. But to tell the machine witth syntax is another thing really :/ what if i selected only one element with do:[] and let its tell me its idices. I store them in a temp object and then I check outside the block the neighbours and add to the counter. Once this is done I repeat as many times as their elements in the matrix?

Re: [Pharo-users] [Moose-dev] [ann] gt connector

by Glenn Hoetker

Wow! This is really cool and has lots of potential use cases. Being able to navigate through classes and their methods this way would be especially helpful in overcoming what Iâve found to be a challenge in Smalltalk. On the one hand, the practice of breaking code into many small methods, each with a single discrete function, offers some real advantages once you get used to it. On the other hand, it does make it harder to understand the gestalt of a class, relative to having everything in a single text file you can just scan through. Lots of pointing & clicking in the system browser, with it being hard to see everything at once. But...being able to have a class, the methods I particularly care about at the moment and the connections between them all visible on the screen at once would be absolutely awesome. It is also something that Smalltalk is uniquely able to offer. Cool!

Iterating over a matrix with do: would iterate over the whole contents of the matrix and the do block gets only called with a single value (the actual element). If you want to iterate over the indices (x/y) you can take a look at the method Matrix>>indicesDo: .
