Distribution of test method name length
by Ben Coman June 24, 2019

June 24, 2019

Working on the Exercism project to shorten generated test method names, for comparison I reviewed the length of test method names in Pharo 7. So just for curiousity value, here is that graph (done in Excel)... [image: image.png] Data generated by... classes := Object allSubclasses select: [ :cc | cc isKindOf: TestCase class ]. methods := c flatCollect: [ :c | c allMethods ]. tests := methods select: [ :m | m selector beginsWith: 'test' ]. lengths := tests collect: [ :m | m selector size ]. lengths asBag keysAndValuesDo: [ :len :count | Transcript crShow: len; show: ','; show: count ] cheers -ben

Question: anyone using NOCompletion setting?
by Marcus Denker June 21, 2019

June 21, 2019

Hi, There are two completion modes currently: the standard one and the NOControler setting the NO option has the idea that it sorts ânewlyâ compiled selectors first, else it is the same. Is anyone using this setting? Marcus

seaside hosting

June 20, 2019

Are there options for hosting seaside apps? I had a look round but didn't see much. I could run it from home I suppose. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Iceberg loading a Tonel package migrated using SETT
by Esteban Maringolo June 18, 2019

June 18, 2019

Hi, I'm trying to load a package from a Tonel repository[1] that was created using SETT[2]. The structure seems fine, but when I try to load a package, I'm getting the message saying that there is no version for the package in the current commit (which seems wrong at least to the naked eye). Eg. [image: image.png] Any idea of how to fix it? Regards! [1] https://github.com/eMaringolo/rbac/tree/master/sources/ [2] https://github.com/gemtalk/sett Esteban A. Maringolo

Autocompletion
by TomaÅ¾ Turk June 18, 2019

June 18, 2019

I managed to find some time to progress with my Smalltalk / Pharo learning and am going through the Spec booklet. I noticed that autocompletion most of the times works excellent, sometimes it struggles. For instance, if you prepare CustomerSatisfaction >> initializeWidgets buttonBad := self instantiate: ButtonPresenter. and then start to write buttonBad label: ... in the same method, the #label: selector is found immediately. However, if you say CustomerSatisfaction >> initializeWidgets buttonBad := self newButton. where ComposablePresenter >> newButton ^ self instantiate: ButtonPresenter and inherited by CustomerSatisfaction, then the #label: selector is not found by autocompleter (in the menu of choices). I'm just curious why is that so. For a novice, autocompleter is a life saver :-) Best wishes, Tomaz

SETT Commit per bundle/package
by Esteban Maringolo June 17, 2019

June 17, 2019

Hi, I don't know if anybody is using SETT to migrate from VW's Store to a Tonel repository, but I'm trying to pull back to Pharo a few packages I moved to VW and continued to maintain there. I don't understand why SETT creates a commit on a "per pundle" (package/bundle) basis. What would be the approach to get a lot of packages working together? E.g. MyPackage-Core, MyPackage-Glorp, MyPackage-Tests, etc. Should MyPackage be a Bundle instead? Regards, Esteban A. Maringolo

How to visit over packages, classes, methods (all types)
by Tim Mackinnon June 17, 2019

June 17, 2019

Hi - is there a way to iterate over all the code in a package (or class or baseline) in a generic way (to pretty print out class definitions, and methods - including extensions ). I was kind of hoping that with TonelWriter and Fileout and Critics that we would have a generic visitor mechanism but it seems that all of them just implemented it again - which misses a big opportunity for refactoring so that when you want to reason/print/manipulate code - it would be more straight forward. Is there anything/anyone addressing this ? Or maybe Iâve missed an obvious trick somewhere? Tim Sent from my iPhone

Introduction GSoC 2019
by Nina Medic June 17, 2019

June 17, 2019

Hello, I am Nina, and I am a student from Serbia. Currently I am on the second year, of my master studies in Computer science. I have been working with Pharo for more than a year now. As a project in one of my classes, I was implementing a program that parses graphs and makes a visualization of them. Last semester I followed MOOC for Pharo. A couple of days ago, I was fortunate enough to be accepted for this year Google Summer of Code. The project I will be working on is called *Graph library with layouting algorithm*. What I will do is implement the graph structure with all necessary parts in one separate library. Beside that I will include layouthing algorithms. Some of which are already implemented as a part of some other projects and packages, those I will pull out. For the other ones, I will be using doctoral dissertation from Vaderna Renata titled *Algorithms and a language for the support of automatically laying out diagram elements*. You can find my proposal here: https://docs.google.com/document/d/1V8_HaZnxYsCfaiZs4vI1C5Dh4TvRPz-H51aYOuY… I would like to know, what are you thinking about this project. How important is for the community? One of fellow students from GSoC (we are both working for Pharo consortium) and I are considering using the same blog. What do you think about that? I will be also posting about my progress on Twitter: https://twitter.com/medicka992 which will make it easy for everybody to follow my work. I am looking forward to working on this project and with all of you. Sincerely, Nina.

Can I code a web browser in a Pharo GUI window (Morphic or other)?
by Arie van Wingerden June 15, 2019

June 15, 2019

Hi, for a project I need this kind of program: 1. client side only 2. must be able to programmatically show a web browser in a window (Morphic??); only local content will be shown 3. must also be able to show other windows, containing simple games Now, I guess that 1 and 3 are possible straight away, but I am unsure about option 2. I found out that there are a few ways to do it: - using C#, which has: - standard web browser control out-of-the-box - third-party open source chromium web browser component - using Java, which (afaict) is a coding effort, but possible anyway That saiud, since I'd very much like to start using Pharo for more tasks (just starting) I wonder if Pharo has something to offer in this case. Many thx! /Arie
