Re: [Pharo-project] TxTextMorph based on new text model
by Fernando Olivero Feb. 21, 2013

Hi, this is really interesting! To have a simpler text model and UI. I recall Safara, in squeaksource. Lukas and a student worked on a nice text model. Worth checking it out.

[Pharo-project] Problems with Metacello
by StÃ©phane Ducasse Feb. 21, 2013

Feb. 21, 2013

Hi Dale I have two questions: first question: className usage in presence of regular package. ------------------------------------------------------------------------------------------- In the following baseline, I do not understand why I'm forced to specify the className because the configuration is based on the project name. spec project: 'OrderPreservingDictionary' with: [ spec ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ without className versionString: #stable; loads: #('Core'); repository: 'http://smalltalkhub.com/mc/Pharo/OrderPreservingDictionary/main']. does not work while spec project: 'OrderPreservingDictionary' with: [ spec className: 'ConfigurationOfOrderPreservingDictionary'; versionString: #stable; loads: #('Core'); repository: 'http://smalltalkhub.com/mc/Pharo/OrderPreservingDictionary/main']. Works baseline200: spec <version: '2.0.0-baseline'> spec for: #common do: [ spec blessing: #baseline; description: 'Migrated to SmalltalkHub and taking into account new configurations of subcomponents'; repository: 'http://smalltalkhub.com/mc/Pharo/XMLWriter/main'. spec project: 'OrderPreservingDictionary' with: [ spec className: 'ConfigurationOfOrderPreservingDictionary'; versionString: #stable; loads: #('Core'); repository: 'http://smalltalkhub.com/mc/Pharo/OrderPreservingDictionary/main']. spec package: 'XML-Writer' with: [spec requires: 'OrderPreservingDictionary']. spec group: 'default' with: #('Core'); group: 'Core' with: #('XML-Writer'); group: 'Tests' with: #() ]. spec for: #squeakCommon do: [ spec package: 'Collections-Support' with: [ spec repository: 'http://www.squeaksource.com/Pharo' ] ]. second question ----------------------- People wrote the following in the baseline spec for: #squeakCommon do: [ spec package: 'Collections-Support' with: [ spec repository: 'http://www.squeaksource.com/Pharo' ] ]. I commented the squeakCommon part because it was loading an old package in pharo! And this package is part of Pharo. Now when I comment the version I do not understand why it is still trying to load a package version because there is already a version in the image. I will remove it from the baseline but I do not understand this behavior. Packages present in the image do not take precedence? version200: spec <version: '2.0.0' imports: #('2.0.0-baseline')> spec for: #common do: [ spec blessing: #release; package: 'XML-Writer' with: 'XML-Writer-JAAyer.5' ]; " I do not understand the following line because it means that we would load an older version than the one currently in Pharo. Clearly the best way to introduce bugs and losing hours trying to understand why. for: #squeakCommon do: [ spec package: 'Collections-Support' with: 'Collections-Support-StephaneDucasse.35' ];" for: #gemstone do: [ spec package: 'Collections-Support' with: 'Collections-Support.g-OttoBehrens.45'; package: 'Collections-Tests-Support' with: 'Collections-Tests-Support.g-OttoBehrens.3' ] Now I do not understand why it loads a package when the package Stef

[Pharo-project] Continuing weirdness with SS3.gemstone.com and Monticello in Pharo 2.0
by phil＠highoctane.be Feb. 21, 2013

Feb. 21, 2013

So, I wanted to merge my stuff from the SS3 project. When loading it needed to have BitBltPen (which I had somewhere as in BitBltPen-MarianoMartinezPeck.4.mcz) I wanted to put that into my SS3 area and so, added the repository to the list of repos in monticello, then took the mcz and then added the repository to the package. Net result: Frozen image. No amount of Cmd-. could do anything. See screenshot. ... now restarting VM... Phil

[Pharo-project] New Issue Tracker
by Camillo Bruni Feb. 20, 2013

Feb. 20, 2013

With the recent announcement of google code to shut down their public API I see a major functionality gone for our project. https://code.google.com/p/support/wiki/IssueTrackerAPI I would like to extend the functionality of our monkey, so it will become more intelligent: - give code critics feedback - reject new code that doesn't meet our criteria in general (unclassified methods / uncommented classes) - failing tests are serialized and attached to the issue - image with the changes integrated are attached to the issue ... you get the picture. All this stuff is impossible to achieve if there is no scriptable API available. By dropping that, google code becomes a silly toy with no further use to me. Requirements ------------ So, we have to come up with a new issue tracker by june with the following requirements: - dead simple issue reporting (most of the stuff out there just looks like a control panel for a space ship) - scriptable API - file attachements Additionally: - programmed in ruby or python - easily create sub-projects ...? Issue Tracker ------------- - I like trac a lot, but no API from what I read http://trac.edgewall.org/ - Jira, thats the space-ship-panel (and in this very same category, buzilla...) http://www.atlassian.com/software/jira - github? too simplistic no file upload https://github.com/dalehenrich/filetree/issues - redmine, possible kandidate http://www.redmine.org/ So what is your take on this?

[Pharo-project] Magritte and Spec

Since I'm using Spec for all my Pharo UIs, I'm interested in having Spec as the backend to Magritte. If anyone is interested, I started an experiment at http://ss3.gemstone.com/ss/SpdPlayground/ . Look for the Magritte-Spec package. Cheers, Sean
