Re: [Pharo-project] direct object manipulation

by Fernando Olivero

Gaucho is under active development, so sadly i cant release it yet. The good news is that i'm using Athens[1], with a Cairo backend. so the visual appearance is greatly improved from the previous version, amongst other goodies such as a zoomable user interface. I'm almost ready for a release... Up to my knowledge, there's no other work related to Self and Morphic Wrappers for Pharo.

[Pharo-project] Pharo and an old plotter

by Pavel Krivanek

Hi, I would like to mention one funny usage of Pharo. I have got an old simple czech plotter from 1989 named XY4150. It is no secret that the interactive environment of Smalltalk is ideal for controlling such machines because it is very easy to send commands to it and experiment with drawing capabilities. Even today such old hardware can find a real-life production deployment. I currently use it to write owner names to plastic cards with pre-printed bar codes by a special pen destined to sign credit cards :-) It is controlled by Arduino however LPT can be used too. Btw. there was several interesting czech plotters. The most interesting one was named Merkur Alfi. It was a construction set for children with two stepper motors and one relay. http://www.youtube.com/watch?v=yUmFYzyL9eo And they started to sell it recently again so if you are looking for some cool hardware for your children, you can look here: http://www.merkurtoys.cz/vyrobky/plotrovy-zapisovac-alfi-z-merkuru[1] But it's about 139â¬ so it's quite expensive... Cheers, -- Pavel

[Pharo-project] Strange deprecation

by Alexandre Bergel

Hi! In 1.4 there is deprecation: MorphicUIManager>>multiLineRequest: queryString centerAt: aPoint initialAnswer: defaultAnswer answerHeight: answerHeight ... self deprecated: 'Use multiLineRequest: queryString centerAt: aPoint initialAnswer: defaultAnswer answerHeight: ' on: '7 September 2011' in: 'Pharo1.4'. ... This is strange since it recommends to use the very same method. I could not find the method I should instead use. Does this method really has to be deprecated?

Re: [Pharo-project] R: Polymorph

by GermÃ¡n Arduino

This is the main reason that motivated my talk in Smalltalks 2010 (Smalltalk and MicroISV's), to show some possibilities of the business side of using Smalltalk. All of us enjoy play with Pharo (or others smalltalks) in our garage to hobbistics projects (myself also!) but we must also use it in business. Thanks for the videos and experiences of Pinesoft, are very motivating!
