Re: [Pharo-users] not a smalltalk!

by kilon alios

AFAIK Pharo technically is not even compatible with Squeak which is where it forks form. You assume the code you write will automatically be incompatible to smalltalk-80 but since pretty much a huge percentage of the functionality of Pharo and Smalltalk is in libraries since the language itself is so minimal , I dont think it would be so hard to make your Pharo code smalltalk-80 friendly. I advice doing your own tests and seeing for yourself. Then ask questions how to solve problems you encounter. No reason to panic before facing the facts :) On Fri, Sep 5, 2014 at 9:33 PM, Yuriy Tymchuk <yuriy.tymchuk(a)me.com> wrote: > There is a long story about all that. > > But to be short: > - if you call it Smalltalk then you have to make it compatible with other > Smalltalks.

by Yuriy Tymchuk

There is a long story about all that. But to be short: - if you call it Smalltalk then you have to make it compatible with other Smalltalks. And they are a lot in the 80sâ¦ - we want to make something new and cool what may be not always compatible.

not a smalltalk!

by Mayuresh Kathe

hey, i've just been reading up the pharo forums, and one of the posts/entries mentions something about pharo not being a smalltalk, but instead a dialect! is it true? that would mean, all or any code i write for pharo would not be portable to other smalltalk-80 systems! hmnn... ~mayuresh

Sure can... Morphic is a different beast, very malleable, glitchy too for now, much better with clean up in Pharo. But the future may see major shifts if Bloc comes through. Spec and my own effort on Pharo Morphic View.. ** https://picasaweb.google.com/skrishnamachari/PharoTabletIDE ** http://skrishnamachari.wordpress.com/2014/09/01/reviving-pharo-morphic-view/ ease the creation a lot.. My effort was a proof I had of how utterly malleable Pharo / Squeak actually is.. I could knock in a new IDE interface with Tree structured code IDE, A simple but effective enterprise class UI framework in around couple of months.. Yes going deeper and getting it technically perfect is much more effort.. But for sure, if you are not weighed down by a career and want to enjoy a ride in the programming world.. nothing better than Pharo Smalltalk for now to hitch too.. though I would enjoy Groovy, Javascript, Python or Ruby for their own uniqueness but primarily as related in the dynamic programming world. -Enjoy..

by the way I forgot to add that I am active at #pharo irc channel at freenode if you want to chat about pharo and ask questions and also you can ask your questions at stackoverflow adding the tag pharo , the pharo community is so active in stackoverflow that I have never seen an unanswered question. here is the tag http://stackoverflow.com/questions/tagged/pharo On Fri, Sep 5, 2014 at 8:25 PM, Mayuresh Kathe <mayuresh(a)kathe.in> wrote: > Cool, thanks for the information. > Also, your "riding a bike" analogy is quite good. :) > Let's see how it goes for me. > > Best, > > ~Mayuresh > > > On 2014-09-05 22:50, kilon alios wrote: > >> I have posted a series of video tutorial for Pharo and in some of them >> I explain the basics of OO with practical examples >> >> https://www.youtube.com/playlist?list=PLqbtQ7OkSta0ULYAd7Qdxof851ybh-_m_ >> [4] >> >> if you throw also PBE I think you pretty much covered. >> >> OO is not really a difficult concept, an object is just a collection >> of variables and methods and then it builds complexity from there.
