Pharo and X11 primary selection (aka middle mouse button paste)
by Pieter Nagel Jan. 25, 2015

Jan. 25, 2015

Our team is very frustrated with figuring out how copy & paste is supposed to work in Pharo 3 under X11. Maybe there's something we misunderstand, or can configure? We can't copy and paste text directly from other X11 apps into Pharo. We need to first paste the text into text editors like GEdit or XEmacs, and then we can copy and paste the text from there into Pharo. I think this has something to do with X11's complicated model of primary vs. clipboard selection. The primary selection is typically created by just highlighting some text, and then (by common convention) can be pasted from by just pressing the middle mouse button. The clipboard selection is typically created by explicitly using Copy or Cut commands. Strange thing is, if we start with text in (for example) Google Chrome, then neither type of selection can be pasted into Pharo. If we start with text in (for example) GEdit, then both types of selection can be pasted into Pharo. We're using Unity under Ubuntu 12.04, if that makes a difference. Advice? Thanks.

It changes the selection on mouse-down instead of on mouse-up. Stephan

I found this article on the popularity of programming languages interesting. http://www.paulgraham.com/popular.html It mostly references Lisp, but I think a lot of the same applies to Pharo. It is quite long so I picked a few points that stood out to me: Some non-technical points... * Nothing could be better, for a new technology, than a few years of being used only by a small number of early adopters. Early adopters are sophisticated and demanding, and quickly flush out whatever flaws remain in your technology. When you only have a few users you can be in close contact with all of them. And early adopters are forgiving when you improve your system, even if this causes some breakage. * Users are a double-edged sword. They can help you improve your language, but they can also deter you from improving it. So choose your users carefully, and be slow to grow their number. Having users is like optimization: the wise course is to delay it. * There are two ways new technology gets introduced: the organic growth method, and the big bang method. ... Organic growth seems to yield better technology and richer founders than the big bang method. If you look at the dominant technologies today, you'll find that most of them grew organically. * Hackers have to know about a language before they can use it. How are they to hear? From other hackers. But there has to be some initial group of hackers using the language for others even to hear about it. I wonder how large this group has to be; how many users make a critical mass? Off the top of my head, I'd say twenty. Some technical points... * There is one thing more important than brevity to a hacker: being able to do what you want. In the history of programming languages a surprising amount of effort has gone into preventing programmers from doing things considered to be improper. This is a dangerously presumptuous plan ... The bumbler will shoot himself in the foot anyway ... Good programmers often want to do dangerous and unsavoury things ... give the programmer access to as much internal stuff as you can without endangering runtime systems like the garbage collector. * It might be a good idea to have an active profiler -- to push performance data to the programmer instead of waiting for him to come asking for it. For example, the editor could display bottlenecks in red when the programmer edits the source code. * It might be a good idea to make the byte code an official part of the language, and to allow programmers to use inline byte code in bottlenecks. * The most important part of design is redesign. Programming languages, especially, don't get redesigned enough. cheers -ben

by HernÃ¡n Morales Durand Jan. 24, 2015

Hi, If you are using Pharo 3 you may install a Nautilus plugin I did which implements the following menu item features: - Jump to the superclass of the currently selected class. - Explore all the instances of the currently selected class. - Send #release and #initialize to the currently selected class - Send (#perform:) the selected unary method to a new instance of the currently selected class. To install evaluate: Gofer it smalltalkhubUser: 'hernan' project: 'HernanPlugins'; package: 'HernanPlugins'; load. Repository: http://www.smalltalkhub.com/#!/~hernan/HernanPlugins Cheers, HernÃ¡n

Glorp on Pharo 4
by Torsten Bergmann Jan. 24, 2015

Jan. 24, 2015

Hi Craig, I've Glorp working with Pharo 4 and NBSQlite3 now without any problem. That's why it is now also in the config browser. As you see from the repo I restructured a bit the "Glorp" package to dig deeper into it and hopefully find the time updating the port once I have access to the VW code. Will update the config in the next available time slot. According to Alan Glorp is now relicensed to MIT thanks to Nial Ross and it would make sense to bring the Pharo port up to date. Thanks T.

Running Pharo headless
by sergio_101 Jan. 24, 2015

Jan. 24, 2015

i am ready to put my seaside app online, and am finding that all the information i am finding is outdated. I am running the latest Pharo (as of last night), and ubuntu14.04. when i try to run using squeakvm, i get: $ sudo ./run 'Your VM is too old for this image. Please download the latest VM.' 'Pharo cannot locate the sources file named /usr/lib/squeak/4.10.2-2614/PharoV30.sources. Please check that the file is named properly and is in the same directory as this image.' A PharoCommandLineHandler is xxxxxxxxx. everywhere i look, the information seems several years old.. ideas? thanks!

The Smalltalk Report issue
by Rafael Luque Jan. 23, 2015

Jan. 23, 2015

Hi Pharoers, I'm looking for The Smalltalk Report volume 6 issue 4 (1997) because I'd like to read the first article mentioning refactoring by Kent Beck: "Make it run, Make it right: Desing through Refactoring" published in this number. I've found the following archive from 1991 to 1996: http://www.macqueen.us/stIndex.html Anyone know where can I found this old issue or at least the article? Thank you.
