Something wrong with my installation of Pharo

by Mark Neagu

Hi, I believe I know why my installation doesn't work: It's not the installation, but something with Windows. I use for years "WindowsÂ 7 Ãdition Familiale Premium 64 bits Service Pack 1" without the slightest problem. But what I use my computer for is simply writing text, taking pictures and exchanging mails; nothing to do with programming. The conclusion, I think, is that some settings of Windows should be modified to adjust to these added uses. The complication is I'm no specialist of Windows; I just use it. That's why I would like a person knowledgeable in Windows AND Pharo, who could check my installation and correct it as needed. To that end we could use "TeamViewer": it wouldn't be overly long or too disturbing for the person. I am very grateful to the person who will accept to help me. Regards, Mark

On which version are you working? I should add an inbox to citezen (waiting to migrate to github). > Thanks to Cyril I have fixed the bug. Now is called > #allSelectorsInProtocol.

Hi offray I generate all my web page and cv with Citezen. Can you tell which version of citezen? how you load it? which version of Pharo the expressions you executed?

They are not kept exactly up-to-date in practice, and having one for each Pharo version is also kind of a bad practice. What is missing is some pushing mechanism that makes sure that configurations from the source repo get promoted to the metarepo when they pass some ci (smoke) tests. Stephan

Depending on MetaRepo instead of the target repo

by Peter Uhnak

Hi, would it make sense to take configurations from metarepos instead directly from the source? And more imporantly: would be considered bad practice for users to do it right now? E.g. spec project: 'Magritte' with: [ spec className: #ConfigurationOfMagritte3; versionString: #stable; repository: 'http://smalltalkhub.com/mc/Pharo/MetaRepoForPharo50/main/' ]. v. repository: 'http://smalltalkhub.com/mc/Magritte/Magritte3/main/' pros: * the (e.g. Magritte) developer can freely change platforms * the ConfigurationOf could differ between various MetaRepo versions (combined with git it could reduce their complexity) * users do not have to think about where is the canonical repo (I've seen project that had copies on SS, STHub, GitHub, and a custom location -_-) cons: * the ConfigurationOf could differ between various MetaRepo versions (if the code is compatible, then two repos have to be updated Any thoughts?
