About Pull Request Reviews: Multiple Reviews are best!
by Marcus Denker May 12, 2022

May 12, 2022

Hi, If you see that a PR that you wanted to review already has a positive review, do not think âah, nothing to be done for meâ. Because imagine if the PR would be bad: you would add a comment how to improve in addition to the one already positive review. You should do the same even if you just add another âYes, looks goodâ. The reason is that *you* know that you looked at the PR and did not find a problem, but nobody else has a way to see that. Second (or even third, 4thâ¦) positive reviews are very valuable, they validate the first review *and* they are vote for getting that PR merged fast. You can find the PRs in need of a review here: https://github.com/pharo-project/pharo/pulls Marcus

Pharo Launcher 3.0.1: no GUI
by Shaping May 12, 2022

On the one where it didnât work, the SDL2.dll file didnât get installed. After adding the file, it opened. Iâm guessing that the virus scanner may be getting in the way. Interesting. I don't have any special antivirus app running, just the default Windows Defender. â¦ I do have SDL2.dll in â¦\AppData\Local\PharoLauncher. Still the GUI doesnât open Hi Christophe. Do we understand why the PL 3.0.1 GUI doesnât open sometimes even when SDL2.dll is present? I have in my PharoLauncher folder 74 items. One of those is the images folder. Is that as it should be? â¦ Should the PL 3.0.1 installer produce a \PharoLancher install folder containing 74 items, of which one is the \images folder? If there is a file/folder list discrepancy, we can start the debugging there. â¦ I rebooted the PC, uninstalled PL 3.0.1, and then reinstalled it. The GUI still doesnât appear, but I have 70 files/folders now (not 74), one of which is \images. The difference seems to be caused by the change in OS state after the reboot. Strange. Any ideas? I still have an SDL2.dll. So, although the absence of this file in Johnâs install explains his missing GUI, it doesnât explain mine. Is anyone besides John and me seeing no PL 3.0.1 GUI on Windows?

About ReToDoRule
by Marcus Denker May 10, 2022

May 10, 2022

I have never seen ReToDoRule to suggest a change that I wanted to do. I think it tries to detect if there is #at: send to the collection inside the block and suggests to use more high-level iterators. But the suggestions are odd and it seems to be too naive with just detecting the #at: message send to the iterated value. "Checks for use of to:do: when a do:, with:do: or timesRepeat: when should be used.â â¢ #timesRepeat: does not take an argument for the block with the running index, so it is not a replacement â¢ with:do: is not a replacement for to:do: ? it would mean creating first a collection and then iterating â¢ using do: on an interval is bad, we even have a rule against that: ReUnoptimizedToDoRule Maybe I am missing something? The rule ReToDoCollectRule seems to be working nicely, though. Issue tracker entry: https://github.com/pharo-project/pharo/issues/11162

Dictionary newFrom: and duplicated keys
by Marcus Denker May 10, 2022

May 10, 2022

Hi, Dictionary class>>#newFrom: right now raises an error if it sees duplicated keys. newFrom: aDictionaryOrCollectionOfAssociations "Answer an instance of me containing the same associations as the argument. Error if any key appears twice." | newDictionary | newDictionary := self new: aDictionaryOrCollectionOfAssociations size. aDictionaryOrCollectionOfAssociations associationsDo: [:x | (newDictionary includesKey: x key) ifTrue: [self error: 'Duplicate key: ', x key printString] ifFalse: [newDictionary add: x]]. ^ newDictionary this leads to an error for: {#a->1. #a->2} asDictionary While just creating it with new and putting the data of course has no problem with duplicated keys: Dictionary new at: #a put: 1; at: #a put: 2; yourself We have a suggestion to remove the error. PR is here: https://github.com/pharo-project/pharo/pull/11176 <https://github.com/pharo-project/pharo/pull/11176> (as a side-effect, this speed up asDictionary a little, too) Marcus

IWST22 â International Workshop on Smalltalk Technologies
by Vincent Aranega May 2, 2022

May 2, 2022

Hi everyone, As you probably know, after complicated years due to the Covid-19 pandemic, the International Workshop on Smalltalk Technologies (IWST) is here again and will be held with this year ESUG conference August 24th to 26th in Novi-Sad, Serbia. Due to authors requests, we moved further the initial deadlines. The 2022 paper review, WiP submission and acceptance processes will proceed with the following deadlines: - Submission deadline: June 1st, 2022 - Notification deadline: July 1st, 2022 - Workshop with ESUG conference: August 24th-26th, 2022. Like last year, we are very proud to announce a Best Paper Award. We thank the Lam Research Corporation for its financial contribution which makes it possible for prizes for the three best papers. We are also happy to announce that accepted papers will be published in the CEUR Workshop Proceedings. IWST has now a significant history and has served for years as a smart playground for young researchers to practice writing articles & presenting results. In parallel, senior researchers take benefit from IWST to expose mature work and propose some retrospective or draw future directions. Mixing these two kinds of contributors makes IWST that attractive. Letâs do the 2022 edition conformed to this legacy! https://esug.github.io/2022-Conference/cfpIWST2022.html Vincent Aranega LoÃ¯c Lagadec

Re: Pharo Launcher 3.0 does not open
by Shaping April 29, 2022

April 29, 2022

Hi Christophe. I tried installing the version below (after uninstalling the old PL 3.0), but I get the same problem. Double clicking the PL icon will create VM instances but no GUI. The Windows Event Viewer says the install completed successfully.

Hi, Indeed, there is a missing lib in the Windows installer. See https://github.com/pharo-project/pharo-launcher/issues/554 Iâm preparing a bug fix release for it. Thank you for reporting. If you cannot wait, you can use this version: https://ci.inria.fr/pharo-ci-jenkins2/job/PharoLauncher-Pipeline/job/dev/18… Christophe Le 28 avr. 2022 Ã 00:14, Shaping <shaping(a)uurda.org <mailto:shaping@uurda.org> > a Ã©crit : Iâm running an updated Windows 10 Pro, and let the Pharo Launcher installer use all the defaults. The uninstalls were thorough and done with CCleaner and Revo Uninstaller. Is everyone able to get Pharo Launcher 3.0 to work? Iâve never had this problem. Shaping ------- My newly installed Pharo Launcher 3.0 doesnât open. Starting the Launcher creates a VM, but no GUI. Every time I start it, TaskMan shows another VM instance, but no GUI appears. I ran the installer twice after a complete uninstall. Anyone having this problem?
