Loading Seaside via Bootstrap in Pharo 6
by Torsten Bergmann Feb. 25, 2017

Feb. 25, 2017

Hi, regarding the problem Sven mentioned on http://lists.pharo.org/pipermail/pharo-users_lists.pharo.org/2017-February/… here are my findings: When I use latest Pharo 6 (Image 60404) and run Metacello new smalltalkhubUser: 'Seaside' project: 'MetacelloConfigurations'; configuration: 'Seaside3'; version: #'release3.2'; load it loads the latest release 3.2 (which internally loads 3.2.1). The package is "ConfigurationOfSeaside3-JohanBrichau.323.mcz" This loads fine in Pharo 6 except that after installation the "Tools" -> "Seaside control panel" is not working anymore as "NewListModel" is not found anymore. So the control panel is broken. Dont know what the migration path is for UI's who used the removed "NewListModel" class. So yes - one can (by using the above script) use Seaside but currently has to start the server with a script until this is fixed. This is good to know - but does not solve the "loading from catalog" issue. ----------------------------------------------------------------------------------------------------------------------------------------- So (in a fresh image 60404) I loaded "Bootstrap" from catalog and I received the error Sven reported. But ConfigurationOfBootstrap itself is not the problem I guess. Because it is also only referencing the "release3.2" version of Seaside and also "ConfigurationOfSeaside3-JohanBrichau.323.mcz" is loaded. The Transcript shows the following error output: Loaded -> ConfigurationOfSeaside3-JohanBrichau.323 --- http://smalltalkhub.com/mc/Seaside/MetacelloConfigurations/main/ --- http://smalltalkhub.com/mc/Seaside/MetacelloConfigurations/main/Error: Name not found: Seaside-Pharo-Development Also when you try to open the ConfigurationOfSeaside3 using Versionner I receiver an error "Name not found: Seaside-Pharo-Development". So there must be something wrong with the Seaside config I thought - or (what would be worse) with the newer Metacello version included in Pharo 6. At least the config looks OK and in both situations "ConfigurationOfSeaside3-JohanBrichau.323" is used. Additionally I tried: - when I load the Bootstrap config in a fresh Pharo 5.0 image (50769) from Catalog all loads fine. - when I manipulate the Pharo 6 image to have a version 5 signature SystemVersion newVersion: 'Pharo5.0'. SystemVersion current inspect. and load from catalog afterwards it also does not work. So I guess a Pharo 5.x specific config rule could not be the cause. Now I checked how Catalog loads the configs. And in class CatalogProject you will notice that for the catalog we still use Gofer for loading installStableVersion Gofer it url: self repositoryUrl; configurationOf: self name; loadStable when I change it to Metacello API installStableVersion Metacello new repository: self repositoryUrl, '/',self name; configuration: self name; version: #'stable'; load what a surprise: anything loads fine. I still wonder and do not know about the difference why Gofer and Metacello loading in Pharo 6 makes a difference now. So we could fix it for the catalog ... still I have no glue about the Gofer/Metacello API difference ... https://pharo.fogbugz.com/f/cases/19736/Catalog-should-use-Metacello-API-in… Thanks T.

Grafoscopio User Manual: Early beta
by Offray Vladimir Luna CÃ¡rdenas Feb. 25, 2017

Feb. 25, 2017

Hi all, I'm making a couple of articles for the JOSS[1], which, by the way is an interesting critic/hack to the anachronistic published paper on indexed journal[2], making visible the work of research who use mainly software as a medium to communicate and make research. [1] http://joss.theoj.org/ <http://joss.theoj.org/> [2] http://joss.theoj.org/about JOSS proposes a pretty good structure for the companion readme file for the software. I started to write it, but I entered to some kind of "writing frenzy" and, after almost 40 pages(!), it ended in the English Grafoscopio User Manual: http://mutabit.com/repos.fossil/grafoscopio/doc/tip/Docs/En/Books/Manual/ma… <http://mutabit.com/repos.fossil/grafoscopio/doc/tip/Docs/En/Books/Manual/ma…> Is the first text I write of such length in English, so any critic on typos, clarity or others are welcomed. Please see the "Community Guidelines" section, particularly "Report issues or problems", so I can follow and address the suggestions better. I will be making some minor updates on the software and the manual to improve consistency (manual URL, remains the same, pointing to the last version). Cheers, Offray <http://joss.theoj.org/>

changing font size in Spec TreeModel or FastTable Tree
by Peter Uhnak Feb. 25, 2017

Feb. 25, 2017

Hi, how can I change the font size of either (or both) Spec TreeModel or FastTable's tree? The font size is by default taken from the StandardFonts defaultFont, but I see no option to change it anywhere for _a specific tree only_. (Also odd that both use #defaultFont and not #listFont). Thanks, Peter

Voyage: refreshing an object back to its repository state
by Hilaire Feb. 25, 2017

Feb. 25, 2017

Hi, Let's say object A is persisted in a Voyage repository. Then object A is modified in memory. Next I want to put object A back to its state as persisted in the repository. As there is some caching in place, doing a 'ObjectA selectAll' will return the modified instance in memory, no access to the DB takes place. As understood, cache can be flushed, but it is overkill, no? Is it safe to just do: VOMongoRepostiry current cache removeObject: objectA to only flush objectA from cache?

Team programming with Smalltalk
by horrido Feb. 25, 2017

Feb. 25, 2017

There's a debate at Hacker News about how Smalltalk is used collaboratively in team programming: https://news.ycombinator.com/item?id=13642947 <https://news.ycombinator.com/item?id=13642947> 'theamk' says: Sorry, I am at work right now and don't have time to watch videos. Can you tell me more about "Smalltalk's own tooling for collaboration and version control"? Are you referring to Monticello? I am not insisting on git, but Monticello seems pretty limited in term of collaboration. I see commit, diff, checkout, and remote pull/push. Specifically, let's imagine this scenario: we have team of tens of programmers working on a project. A new team member joins and accidentally breaks the code in non-obvious way. He pushes the code to main repository. Next time, everyone else checks out the latest version of the code and starts having weird problems. If you had 20 people on team, and they each wasted 2 hours because the code was broken, well, you just wasted a week of programmer time. How do you prevent it? In file-based word, the answer is tests and CI. What is the smalltalk way? And please do not say "It's in the conceptual nature of programming" -- if the scenario makes no sense in the smalltalk world (maybe you are not supposed to have 20 people working on the same project?) please say this. ----- How would you respond? I know Smalltalk can be used in large team programming, but since I personally have no experience with this, I cannot respond intelligently. Thanks. -- View this message in context: http://forum.world.st/Team-programming-with-Smalltalk-tp4934508.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

[Verssioner] Committing changes -> "SubscriptOoutOfBounds: 1"
by sergio ruiz Feb. 24, 2017

Feb. 24, 2017

For some reason, when i use Versionner to commit my changes to my configuration, I consistently get: "SubscriptOoutOfBounds: 1â If i make changes to my project, and just run Kommmiterâ¦ instead of getting my remote (for the changes to my project classes) i get a âNew Sliceâ and cannot select the remote for those classes.. Any ideas on what I am doing wrong?
