SmartTest
by Benoit Verhaeghe July 5, 2017

July 5, 2017

Hi everyone, Iâm working on a new plugin for Nautilus/Calypso that will help us with the test. The goal is to provide us the selection of tests we should run after a modification. It would be great if you accept to try it or want to use it. Currently, by installing the plugin, when you select a method in Calypso or Nautilus, you will see a new critique that will offer you to run the test relative to the method youâve selected (or class ^^ ) Another goal is to calculate the efficient of this new tool and how we will use it. Itâs why Iâve also developed a plugin that will record how we will use the plugin. If you accept to help me. Please tell me ( so i will be able to estimate how many data I will obtain ). Now the commands. If youâd like to help me. The command is simple : Metacello new smalltalkhubUser: 'badetitou' project: 'TestsUsageAnalyser-CoraExtends'; configuration: 'TestsUsageAnalyser_CORAExtends'; version: #stable; get; load. If youâd like to use the plugin or just want to try it. Itâs also simple Metacello new smalltalkhubUser: 'badetitou' project: 'CORA'; configuration: 'CORA'; version: #stable; get; load. For the version with Calypso ( because itâs cool ). Metacello new smalltalkhubUser: 'badetitou' project: 'CORA'; configuration: 'CORA_Calypso'; version: #stable; get; load. So, if you want to help me and use calypso you should run the first and the third command. Options for the plugin are available in the settings of Pharo in the group : âTestRegressionâ. So you can extend the plugin with your own logic of testing strategy. To disable the spy (first package) in the option please uncheck âTest Usage Analyserâ Iâm going to write a blog post that will explain all the plugin and how to use it. If you find bugs ( But there are no bugs ;) ) please tell me and i will fix it as soon as possible. If youâd like that I add a feature, tell me too. Thanks a lot for your help. BenoÃ®t Verhaeghe

Pull requests reviews
by Pavel Krivanek July 5, 2017

July 5, 2017

I prepared a script that should help you with the reviews of the pull requests on Pharo 7. We will later convert it into a more fancy tool. It does next steps: - sets the basic information: pull request number, path to your pharo repository clone, name of your fork. - registers the repository into Iceberg and sets pull and push target remotes - switches branch to a particular commit from which the Pharo image was bootstrapped - registers the repository into into Monticello packages to be able to do correct diffs - gets basic information about the pull request from GitHub (original repository, branch name) - registers the PR original repository into remotes if needed and fetches information from it - creates a new local branch to merge the PR - merges the PR branch - displays a simple tool that shows differences in done in this merged branch -------- pullRequest := 73. target := '/path/pharo' asFileReference. myForkName := 'myFork'. repository := IceRepositoryCreator new location: target; subdirectory:'src'; createRepository. repository register. fork := repository remotes detect: [ :remote | remote remoteName = myForkName ]. repository pushRemote: fork. repository pullRemote: repository origin. repository checkoutBranch: (SystemVersion current commitHash). fileTreeRepository := (MCFileTreeRepository new directory: target / #src; yourself). repositoryGroup := MCRepositoryGroup withRepositories: { fileTreeRepository. MCCacheRepository uniqueInstance. }. MCWorkingCopy allManagers select: [ :wc | (wc repositoryGroup repositories reject: [ :repo | repo isCache ]) isEmpty ] thenDo: [ :wc | wc repositoryGroup: repositoryGroup ]. stonString := (ZnEasy get: ' https://api.github.com/repos/pharo-project/pharo/pulls/', pullRequest asString) contents. head := (STONJSON fromString: stonString) at: 'head'. sshUrl := (head at: #repo) at: 'ssh_url'. branchName := head at: #ref. user := (sshUrl withoutPrefix: 'git(a)github.com:') withoutSuffix: '/pharo.git'. fork := repository remotes detect: [ :remote | remote remoteName = user ] ifNone: [ | newFork | newFork := (IceRemote name: user url: ('git@github.com:{1}/pharo.git' format: {user})). repository addRemote: newFork. newFork ]. repository fetchFrom: fork. prMergedBranchName := 'pr', pullRequest asString. repository createBranch: prMergedBranchName. repository checkoutBranch: prMergedBranchName. commit := repository revparse: user, '/', branchName. bootstrapCommit := repository revparse: (SystemVersion current commitHash). [ repository backend merge: commit id ] on: IceMergeAborted do: [ :error | repository mergeConflictsWith: commit ] . headCommit := repository revparse: 'HEAD'. browser := GLMTabulator new. browser row: [:row | row column: #commits span: 2; column: #changes span: 3]; row: #diff. browser transmit to: #commits. browser transmit to: #changes; from: #commits; andShow: [ :a :commitInfo | (IceDiffChangeTreeBuilder new entity: commitInfo; diff: (IceDiff from: commitInfo to: bootstrapCommit); buildOn: a) title: 'Changes'. ]. browser transmit from: #commits; from: #changes; to: #diff; andShow: [ :a | a diff title: 'Left: working copy / Right: incoming updates'; display: [ :commitInfo :change | { change theirVersion ifNil: ''. change myVersion ifNil: ''. }]]. browser openOn: {headCommit}. -------- The merge operation only changes the Git working copy, no code is loaded into the image. If you want to test the PR code, currently you need to open Iceberg and reload all packages in the Pharo repository (Packages tab, Reload all) Expect troubles :-) Cheers, -- Pavel

Hi, I got problem with my Pharo6 image when I save it, after some Glamour try out, don't know if it is related. When I saved the image, it grows to 292MB then stalled, with the mouse writing pointer. Then Pharo display became garbage. I have to kill the process.

[ANN] Iceberg 0.5 released
by Esteban Lorenzano July 5, 2017

July 5, 2017

Hi all, Iâm releasing 0.5 version of iceberg. This is the changelog: Major changes: ---- - works on 64bits - adds cheery-pick Other: ---- This version also includes a list of fixes, most important one is this: - branchs are kept inline with local working copy (so if you change a branch in command line or in another image it will indicate it correctly) But there are many others, next version will have a full list, I promise :) Now, to actually use it you will need to accomplish several steps (until I update the image) 1) You need to download the new stable VM for P7 (it does not matters if you are on P6). Zeroconf: 64bits: wget -O- get.pharo.org/64/vm70 <http://get.pharo.org/vm70> | bash wget -O- get.pharo.org/ <http://get.pharo.org/vm70>64/ <http://get.pharo.org/vm70>vmT70 <http://get.pharo.org/vm70> | bash #If you are on linux 32bits: wget -O- get.pharo.org/vm70 <http://get.pharo.org/vm70> | bash wget -O- get.pharo.org/vmT70 <http://get.pharo.org/vm70> | bash #If you are on linux then, to update, execute this (sorry, this is like that because we have still an older Metacello version): #('Iceberg-UI' 'Iceberg-Plugin' 'Iceberg-Metacello-Integration' 'Iceberg-Libgit' 'Iceberg' 'BaselineOfIceberg' 'LibGit-Core' 'BaselineOfLibGitâ) do: [ :each | each asPackage removeFromSystem ]. Metacello new baseline: 'Iceberg'; repository: 'github://pharo-vcs/iceberg'; load. cheers! Esteban

[ANN] for P7, default VM for linux moved to threaded
by Esteban Lorenzano July 5, 2017

July 5, 2017

Hi, I made default vm for linux (for P7) the default VM. I also updated zeroconf to add a new type of download for linux: the explicit iTimer heartbeat download. So, for P7, if you download the default stable VMâ¦ it will be a threaded VM. Take that into account :) Esteban

Reflecting on data (literal) object syntax
by Stephane Ducasse July 5, 2017

July 5, 2017

Hi recently I started to read a book on machine learning and they manipulate dictionary of dictionary. (So I started my own implementation and I will switch to DataFrame). Now it occurred to me that when we program complex objects we do not need a compact literal syntax for our objects. But when we manipulate data objects it is super handy. I ended up doing a lot of self new addRow: 'Claudia Puig' withTaggedValues: {('Snakes on a Plane' -> 3.5). ('Just My Luck' -> 3.0). ('The Night Listener' -> 4.5). ('Superman Returns' -> 4.0). ('You, Me and Dupree' -> 2.5)}. And I was not in the mood to write a class for the taggedValues and writing a class would not have really help me. Now we also have STON but STON is not yet part of the language grammar. So we have to have an explicit conversion call. STON fromString: 'Point[10,20]' We were brainstorming with marcus and we could have a first nice extension: { 'x' -> 10 .'y' -> 20 } asObjectOf: #Point. >>> 10@20 Now in addition I think that there is a value in having an object literal syntax. I pasted the old mail of igor on object literals because I like the idea since it does not add any change in the parser. Do you remember what were the problem raised by this solution (beside the fact that it had too many # and the order was like in ston not explicit). I would love to have another pass on the idea of Igor. Stef ---------- Forwarded message ---------- From: Igor Stasenko <siguctua(a)gmail.com> Date: Fri, Oct 19, 2012 at 1:09 PM Subject: [Pharo-project] Yet another Notation format: Object literals To: Pharo Development <Pharo-project(a)lists.gforge.inria.fr> Hi, as i promised before, here the simple smalltalk-based literal format. It based on smalltalk syntax, and so, unlike JSON, it doesn't needs to have separate parser (a normal smalltalk parser used for that). The idea is quite simple: you can tell any object to represent itself as an 'object literal' , for example: (1@3) asObjectLiteral --> #(#Point 1 3) { 1@2. 3@4. true. false . nil } asObjectLiteral -> #(#Array #(#Point 1 2) #(#Point 3 4) true false nil) (Dictionary newFromPairs: { 1->#(1 2 3) . 'foo' -> 'bar' }) asObjectLiteral -> #(#Dictionary 1 #(#Array 1 2 3) 'foo' 'bar') Next thing, you can 'pretty-print' it (kinda): #(#Dictionary 1 #(#Array 1 2 3) 'foo' 'bar') printObjectLiteral '#(#Dictionary 1 (#Array 1 2 3) ''foo'' ''bar'')' and sure thing, you can do reverse conversion: '#(#Dictionary 1 (#Array 1 2 3) ''foo'' ''bar'')' parseAsObjectLiteral a Dictionary('foo'->'bar' 1->#(1 2 3) ) Initially, i thought that it could be generic (by implementing default Object>>#asObjectLiteral), but then after discussing it with others, we decided to leave Object>>#asObjectLiteral to be a subclass responsibility. So, potentially the format allows to represent any object(s) as literals, except from circular referencing objects, of course. The implementation is fairly simple, as you may guess and contains no new classes, but just extension methods here and there. Take it with grain and salt, since it is just a small proof of concept. (And if doing it for real it may need some changes etc). Since i am far from areas right now, where it can be used, i don't want to pursue it further or advocate if this is the right way to do things. Neither i having a public repository for this project.. So, if there anyone who willing to pick it up and pursue the idea further, please feel free to do so and make a public repository for project.

[ANN] Pharo community addon for world menu
by Torsten Bergmann July 4, 2017

July 4, 2017

Hi, I added a small utility called "Community" to the catalog that allows you to quickly access/browse the most prominent Pharo pages (Homepage, Discord, Mailinglist Archive, CI Server, Books page, Association, Consortium, STHub) right from the world menu. Also in Spotter. Example: ======== Load Community from Pharo catalog. As the menu entries are mirrored also in Spotter you can easily open Spotter, key in "Discord" hit enter and the local web browser should open the Pharo chat. Attached is a screenshot. Maybe this is useful for others too. Have fun T.
