[ANN] Cheer for THE Medusa - the single Smalltalk based battle snake

by Jerry Kott

Hi lists, you may recall a mention of Battlesnake in these forums before. Today, the Battlesnake team is holding an online tournament that you can watch live on Twitch: https://www.twitch.tv/battlesnakeofficial <https://www.twitch.tv/battlesnakeofficial>. My entry THE Medusa is the only Smalltalk-based battlesnake in the competition. It’s listed in the Group D of the Veteran division. Not sure when it’s going be on - currently the Rookie division is playing. I hope you can join, watch, have some fun, get inspired to write and enter your own Smalltalk based snakes for future competition (the arenas are open year-round so you have plenty of time to test your snakes), and if you can, donate a small amount to Food Banks Canada in support of families affected by COVID-19. Cheers, stay safe & stay healthy. Jerry Kott This message has been digitally signed. PGP Fingerprint: A9181736DD2F1B6CC7CF9E51AC8514F48C0979A5

Participate to the Magic Literal XP

by Stéphane Ducasse

Dear all, We are running a large XP for a research around Magic Literals. A magic literal is a literal (number, booleans,…) that is used to denote something but that it not immediately obvious to the code reader: it can be for example a number but could be also a string, a character or boolean (this is what we want to discover). When you read the code you should be puzzled by the usage of this magic encoding and this is what we want to understand and that you report to use using a special tool. Now identifying magic literal is not easy and we want to measure them. We already did a publication at ESUG last year (but we only did an XP with 100 methods) and now we want to go the world. If you want to read it https://hal.inria.fr/hal-02266137/document Our idea is to have result first in Smalltalk and then, only then check with Java :). But for that we should show to the world that we did a large XP. So we build one and now we need you to help. First we need to evaluate the situation and understand the different cases, as not all literals are "magic". You can help us in this. It can take you 30 min for one experience. In the shared directory https://www.dropbox.com/sh/ag94vutsrtcs0n9/AAAEkpB2onlWpcFLqLPKOpOaa <https://www.dropbox.com/sh/ag94vutsrtcs0n9/AAAEkpB2onlWpcFLqLPKOpOaa> there are images for different experiments (on whole Pharo, on Roassal, Polymath, VM maker, Seaside project, …) We want to compare the analysis of an expert and an external person on a domain this is why we will cross comparison between roassal expert and roassal newbie (same for Seaside, Polymath, VMMaker) These images contain the code and the tool for the experiment and they should be open with Pharo80 you can get from http://www.pharo.org To participate in the experiment: - Step 1. go to the document https://docs.google.com/spreadsheets/d/1DrjXcfuR8Ja_7luknUUfijO8wzYYaJ2ZP_p… <https://docs.google.com/spreadsheets/d/1DrjXcfuR8Ja_7luknUUfijO8wzYYaJ2ZP_p…> - Step 2. select one experiment to do (for example put your name in the column 'Doing’) add your expertise to the sheet - Step 3. please select the experiments in numerical order, e.g. do the Pharo-1 experiment before the Pharo-2 one. Note that a Lot will contain also some other methods because we are mixing methods to collect more information so do not be surprised to see other methods that Polymath’s ones in the polymath XP. - Step 4. Get the tool on the experiment. >From the list grab an inspector and execute MLSExperimentPresenter openOnSample: self ' with the batch you chose as argument You should get the following tool (with different colors :) - yes that theme is funky) . - Step 5. decide whether each literal presented is Magic or not (unabling ‘Hide completed' can help) Remember: 'A magic literal is a literal (number, booleans,…) that is used to denote something but that it not immediately obvious to the code reader' - Step 6. completing one experiment should take less than 30 minutes - Step 7. when done, save the result (button at the bottom of MLSExperimentPresenter) - this will give a STON file named after your batch. - Step 8. You need to send us this file (email at nicolas.anquetil(a)inria.fr <mailto:nicolas.anquetil@inria.fr>) Your identity will be discarded from the data (anonymous answers). But we will owe you a beer at ESUG or Pharodays :) We will use it only to assess your expertise in Pharo and/or the project evaluated. Many thanks for your help in improving pharo and our understanding of the literals (magic or not) Nicolas, Stephane, Julien, Christopher and Oleksandr -------------------------------------------- Stéphane Ducasse http://stephane.ducasse.free.fr / http://www.pharo.org 03 59 35 87 52 Assistant: Julie Jonas FAX 03 59 57 78 50 TEL 03 59 35 86 16 S.

Dear ESUG member, I would like to publicly send a big clap to Loic Lagadec and Anne Etien for their remarkable work on getting a special issue for the IWST proceedings. This special issue, in the Science of Computer Programming journal, has a real and tangible impact on the future of our students and young professors. Loic, Anne, you are making the world a better place.

Hi Stef, I’ve done some workshops and screencasts. In the workshops (oops, already a few years ago) I used a morph that was moving on the screen to emphasize the liveness. The BabyMock2 work by Attila Magyar is also great for that. It also is good to show the difference between Chicago and London style TDD, and connect to BDD. In Smalltalk, that is more represented by the exploratory modeling I was introduced to by Rob Vens. https://www.reflektis.nl/blog/exploratory-modelling-explained/ For a lecture TDD as if you meant is is a good starting point: https://cumulative-hypotheses.org/2011/08/30/tdd-as-if-you-meant-it/ GToolkit of course provides some nice example-driven development, that combines well with literate programming In my latest screencasts I ran into the following issues: - restarting a test does not make it green after going through it if it needed a fix - can’t step into simple accessors (and other optimized code?) - in addition to create, need to be able to create/change setUp/initialize/shutDown - a refactoring ‘turn fake into class’ is missing where instVar := self and there are methods categorized as ‘faking instVar’ https://vimeo.com/329317634 https://vimeo.com/329368348 Stephan Verstuurd vanaf mijn iPhone > Op 14 apr. 2020 om 14:36 heeft Stéphane Ducasse <Stephane.Ducasse(a)inria.fr> het volgende geschreven: > > Hello > > I would like to build a lecture around TDD and XtremeTDD (coding in the debugger). > I’m looking around to see if someone already did such a lecture. > > S. > -------------------------------------------- > Stéphane Ducasse > http://stephane.ducasse.free.fr / http://www.pharo.org > 03 59 35 87 52 > Assistant: Julie Jonas > FAX 03 59 57 78 50 > TEL 03 59 35 86 16 > S.
