Binary search is extremely useful to quickly find something in a sorted collection, like finding if a string or number is included in a large collection. BTW, we already have an implementation, see SequenceableCollection>>#findBinary: and friends. > On 10 Jul 2019, at 18:53, Alexandre Bergel via Pharo-users <pharo-users(a)lists.pharo.org> wrote: > > > From: Alexandre Bergel <alexandre.bergel(a)me.com> > Subject: Re: [Pharo-users] [GSoC blog post] Binary Search Trees > Date: 10 July 2019 at 18:53:01 GMT+2 > To: Any question about pharo is welcome <pharo-users(a)lists.pharo.org> > > > Hello Smiljana, > > Thanks for having written down this document. I am not expert in algorithm, so I would consider myself a simple user. I have developed complex software for some times and I have never seen the need of having a binary search tree. I guess this is probably partly because of my lack of expertise in binary search tree and partly because experts in binary search trees assume that people know what it is about and in what it is useful. > > My question is, when should a programmer ever need to use binary search tree? Can you add some examples on what these trees are good for, and how an average programmer should look into it.

Change code critics to decrease size of navigation pane?
by PAUL DEBRUICKER July 9, 2019

July 9, 2019

Hi - Sometimes (all the times) I write method that violate a critics rule. The quality improvement pane, when it expands, shrinks the code editing pane. Can I change that so that it shrinks the height of the navigation panes instead e.g. the class list etc? Stopping writing "offensive" methods seems impossible. Thanks Paul

Comparing to commits in Iceberg
by Esteban Maringolo July 9, 2019

July 9, 2019

Is there a way I can compare, and eventually merge, two arbitrary commits with Iceberg? E.g. I'm working on the latest commit of the master branch and want to see what changed against two commits ago, and maybe roll back some change. Regards, Esteban A. Maringolo

[ANN] Pharo Launcher 1.9.1 released
by Christophe Demarey July 8, 2019

July 8, 2019

Hi all, We are pleased to announce Pharo Launcher 1.9.1 release! The goal of this release is to have a better Windows support. Indeed Pharo Launcher now uses a new library OSWinSubprocess (https://github.com/pharo-contributions/OSWinSubprocess <https://github.com/pharo-contributions/OSWinSubprocess>) created for Pharo Launcher needs. This library allows to create Windows processes through ffi calls to the Windows API. It uses the unicode api, allowing paths with non-ascii characters. In the same time, we switched from OSProcess to OSSubprocess (Linux and OS X) that is now the preferred library to use to fork processes on Linux-based systems. This release is not yet the default download of Pharo Launcher on Pharo web site because we want more feedback before promoting it. Please use this link to install it: https://files.pharo.org/pharo-launcher/1.9 <https://files.pharo.org/pharo-launcher/1.9> and let us know if this version works fine/better for you. ps: For now, the binary is not signed but it will come soon. ps2: Thanks to Keldon Alleyne for his PR on Pharo Launcher offering the first FFI binding to Windows process API Regards, The Pharo team.

Cryptography decrufted
by Norbert Hartl July 5, 2019

July 5, 2019

I cannot remember how many years Iâm suffering with the poor quality of the Cryptography package. As people were complaining that voyage cannot be loaded in windows because cryptography contains old code that produces filenames with 311 charactern I decided to stop that. I changed the Cryptography repo in a way that: - all packages that are old squeak related have been removed - packages that could not be loaded into a pharo7 because of dependencies I donât know have been removed - loadable packages have been added in the baseline in the all group so everything is loaded and tested in travis - tests have been fixed where I could do that easily - tests that were failing and I donât know why have been added (with a comment) to expectFailures - after the removal I did a new version 0.4 for those who are interested in the cleaned old version - then I converted the source into tonel format - then I retired pharo4 and pharo5 for the travis builds because 3 yearsis enough for such a package - finally I did a version 0.5 with that state There were also packages removed like PasswordHashingFFI and CryptographyPlugins. Not sure if the FFI variant is recent or the CryptographyPlugins realtes to the vm. I removed every package in its own commit. So resurrecting a package should be easy as reverting a commit if someone needs it. Now Iâm udpating mongotalk and voyage. FYI, Norbert

Re: Test Completion has been added to Pharo 8 - please test!
by Myroslava Romaniuk July 3, 2019

July 3, 2019

Hi Stef So the more detailed instruction with the screenshot is in the blog post : https://medium.com/@myroslavarm/test-code-completion-has-been-added-to-phar…, but simply put: if you go to settings, type in 'completion' in the search bar, and where it says 'controller' change it to 'TestCompletionController', you will have it. It will be inside the environment instead of the regular completion, so any time you type something in playground or editor, it will be the test completion that is triggered. Basically to test it you only need to be coding something in Pharo :) So if you use it and it breaks somewhere, let us know.

Test Completion has been added to Pharo 8 - please test!
by Myroslava Romaniuk July 2, 2019

July 2, 2019

Hi all, we added an intermediate version of the upcoming test completion to Pharo 8, it would be cool if you tested it and let us know the results. Here's a blog post about it - link <https://medium.com/@myroslavarm/test-code-completion-has-been-added-to-phar…>, and here's a tweet I'd be grateful if you shared - link <https://twitter.com/myroslavarm/status/1146013653067587584> so perhaps people who don't read the mailing list would also see it. In the blog post you can find more info how to enable the completion in the settings and details about the whole thing in general. If something doesn't work, or if something works differently than it used to in the old completion (both if you don't like it or perhaps if you prefer it) let me know either replying here, on twitter, or submitting an issue request directly for the github repository here - link <https://github.com/myroslavarm/Experimental-Completion/issues>. Thanks very much, Myroslava
