[Voyage] #selectOne: and #selectMany: with a block as the argument
by Bernat Romagosa July 9, 2013

July 9, 2013

Hi! I realize probably only Esteban will be able to answer, but I prefer to write to the list so the mail is logged and other people can benefit from it. I'm trying to use blocks as arguments for #*selectOne:* and #*selectMany:*, but it doesn't seem to work. Here's my code: MyClass selectOne: { #name -> 'Some name' } asDictionary. MyClass selectOne: [ :each | each name = 'Some name' ]. The first one works, but the second one raises a *VOMongoConnectionError*. Also: MyClass selectMany: { #name -> 'Some name' } asDictionary. MyClass selectMany: [ :each | each name = 'Some name' ]. The first does work, the second one doesn't, which prevents me from writing more useful stuff like: MyClass selectMany: [ :each | each name first = $P ]. Any idea why this could be failing? I've the latest stable version loaded via: Gofer it url: 'http://smalltalkhub.com/mc/estebanlm/Voyage/main'; package: 'ConfigurationOfVoyageMongo'; load. (Smalltalk at: #ConfigurationOfVoyageMongo) load. Thanks! :) Bernat. -- Bernat Romagosa.

Deactivate method inlining/jitting
by Norbert Hartl July 9, 2013

July 9, 2013

I'm analyzing some code and what I do does not work for e.g. ifTrue:ifFalse. Is there a way to (temporary) deactivate using the jit or any optimization that handles those methods special? Norbert

[ANN] Pharo Launcher
by Damien Cassou July 9, 2013

July 9, 2013

Dear list, Erwan and I are proud to announce the first release of the Pharo Launcher, a cross-platform application that - lets you manage your Pharo images (launch, rename, copy and delete); - lets you download image templates (i.e., zip archives) from many different sources (Jenkins, files.pharo.org, and your local cache); - lets you create new images from any template. A screenshot is attached to this email. The idea behind the Pharo Launcher is that you should be able to access it very rapidly from your OS application launcher. As a result, launching any image is never more than 3 clicks away. Download: https://ci.inria.fr/pharo-contribution/job/PharoLauncher/PHARO=30,VERSION=b… Please report bugs on the 'Launcher' project at https://pharo.fogbugz.org You can contribute to this project. All classes and most methods are commented. There are unit tests. Please contribute! Source code: http://www.smalltalkhub.com/#!/~Pharo/PharoLauncher CI: https://ci.inria.fr/pharo-contribution/job/PharoLauncher Things you can do to improve the system: - check if a template is already downloaded before downloading it - add a preference mechanism (for, e.g., quit after launch, definition of your own template groups, location of downloaded templates and images) - put the launcher in the Pharo Ubuntu package so that the launcher becomes a registered appliation of the system (https://launchpad.net/~pharo/+archive/stable) - make sure the pharo launcher does not load your personal scripts (like fonts and MC configuration) - add a toolbar to enhance the discoverability of the features (currently everything is in contextual menus) - make sure rename and copy actions propose default values - make sure no debugger pops up when a user press cancels or enter an invalid name - propose multiple kinds of sorting (last used, most frequently used, alphabetically on the name) - give some information about each template (build date, pharo version) -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

Enforcing uniqueness constraints in Voyage-Mongo
by raphonic July 9, 2013

July 9, 2013

Hi, I would like to know how to set certain instance variables of my models to be unique and also if there is a mechanism to set other constraints(like presence of an embedded object) in Voyage-Mongo. I searched the MongoDB docs and it says that constraints should be implemented at the application level. Does Voyage have any support for setting constraints? -- View this message in context: http://forum.world.st/Enforcing-uniqueness-constraints-in-Voyage-Mongo-tp46… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Hi, I've just created a new team for MongoTalk on SmalltalkHub: http://www.smalltalkhub.com/#!/~MongoTalkTeam The old repo (http://www.smalltalkhub.com/#!/~francois/MongoTalk) will stay just in case some scripts rely on it but you should update to the new repo: http://www.smalltalkhub.com/#!/~MongoTalkTeam/mongotalk I've created a version 1.5.1 in the Metacello configuration to reflect the repo migration. Shout at me if I missed something! Cheers, Fa (Many thanks to Norbert for pushing the migration ;)

by phil＠highoctane.be July 8, 2013

July 8, 2013

Hello, I am currently working with a dataset in CSV format and am trying to load it in to Moose for visualizations with Mondrian. Now, I am facing an issue with NeoCSV. I loaded the Configuration in Moose without trouble. Now, when loading my file, I do get a MNU with SmallInteger codepoint Is this a Moose issue or a NeoCSV issue ? I've tried to comment out the codepoint message to see where this was going but to no avail. Clues? TIA Phil [image: Inline image 2][image: Inline image 1]

documentation for refactoring tools in Pharo 2
by Paul DeBruicker July 5, 2013

July 5, 2013

Is there any documentation on the changes between 1.4 and 2 for the refactoring tools? Or how to use them effectively to refactor code? I'm familiar with Lukas Renggli's writing on them and used them regularly in 1.4. I'm just trying to use the RBParseTreeRewriter from within a workspace but with it limited to a package or class heirarchy. Thanks Paul

Regex question
by jannik.laval July 5, 2013

July 5, 2013

Hi guys, Just a simple question about regex: 'a' matchesRegex: '.' --> true 'aa' matchesRegex: '.' --> false As '.' represents any character, the two previous lines are ok. Now, if I test with a cr, it returns true: String cr matchesRegex: '.' --> true. Is it the expected behavior ? Cheers, Jannik

We need you for a software integration survey (reminder)
by Martin Dias July 5, 2013

July 5, 2013

Hi all, Some time ago we sent an email to ask you contributing to a research to improve tools for software integration. If you maintain a project with multiple contributors, we will greatly appreciate your participation. Your answers will be used for research purposes and to support the development of new tools. You can later access the results of this study, make free use of our tools to support the integration of changes, and maybe receive a gift. We found out that the survey was not properly working on Safari (and may be also some other browsers). And we have now corrected this issue. Up to now, we received 36 full answers and 166 incomplete answers. So we decided to give you an extra month, if you started to fill the survey, please consider resuming filling the survey. For this you only need to go back to the same site: https://sondages.inria.fr/index.php/667625/lang-en If you did not yet fill in the survey, please consider doing it now. Best regards, Martin Dias, Nicolas Anquetil, Veronica Isabel Uquillas, StÃ©phane Ducasse and the RMOD Inria team
