Also, more hands are always needed for reviewing "resolved" issues to avoid them languishing. Often issues might only get one reviewer when ideally there would be two reviewers. This has a few advantages for you. * There is a lot of old code in Pharo with varying conventions. The best place to learn Pharo's conventions is "new" code. * It mitigates the "parts of the system I don't know" issue - since code changes are location specific. * You learn about system parts is a goal directed fashion (which works best for me rather than just browsing) cheers -ben

Hi Sergio, It is great that you want to contribute ! Have you seen http://pharo.org/contribute and more specifically http://pharo.org/contribute-propose-fix ? It is a bit of work to get started, but once you have everything set up and understand the process, the next contribution will go much faster!

Re: [Pharo-dev] Where to start contributing

by Cyril Ferlicot

Hi, there is many things you can do. - you can use the Pharo 5 image and check for something wrong, if you find one you can talk about it on the Mailing list and open a bug entry. (If you don't know the PharoLauncher you should take a look: http://www.smalltalkhub.com/#!/~Pharo/PharoLauncher that is an easy way to get latest image of Pharo all the time) - Try to correct bugs on https://pharo.fogbugz.com/f/ You can use the filter to select only the things you know about (filter: All (by projects) ) - You can help to improve Pharo. For example if you improve the About text of Versionner you can create a bug entry and send a slice on Pharo5Inbox with your improvement. If that's good enough The Integrator will add it on future release of Pharo 5 - You can also create your own project like Yuriy and his QualityAssistant but if you want to do that, PLEASE, ask on the mailing list if someone don't do that already. That would be sad to have 2 people working on the same thing without knowing.

Improving the About Text of Versionner

by Sergio Fedi

This seemed a fairly easy change so I can keep honing my contributing skills. I came up with this About text for the tool. Below is a screenshot on how it looks: â Here's the text: *Versionner is a GUI for Metacello that allows you to use a nice (but limited, as are most GUI tools) tool instead of writing configs by hand.* *Metacello is a package management system that declares dependencies between* *those packages in configuration classes.* *Monticello is our SCM system that groups code into packages.* *For a tutorial video on how to use Versionner:* * https://youtu.be/cFRJDuWL-Q0 <https://youtu.be/cFRJDuWL-Q0>*

Where to start contributing

by Sergio Fedi

As a fairly experienced Smalltalk programmer but a very new user of Pharo, Where do you guys suggest me to start contributing? To be more specific, there are parts of the system I don't know, and practices and conventions of Pharo that I don't grasp yet, so it seems that work that can be done withour relying on that knowledge would be more suitable for me. I'm open to a pair programming session via Skype/Teamviewer or other medium. For example, I was contemplating on defining the About text for the Versionner in light of the recent discussions.

Re: [Pharo-dev] TextMorph right-click?

by Nicolai Hess

I think this is a bug, introduced early in the move from squeak to pharo. (It used to work in squeak). Although we don't have any use of a "pure" TextMorph (I don't know of any place/project, either it uses String/LabelMorphs for texts or it uses another TextEditorMorph), without any pluggableXXXMorph around it, I think we should fix this. 2015-05-02 12:44 GMT+02:00 Ben Coman <btc(a)openinworld.com>: > > On Sat, May 2, 2015 at 5:31 PM, Stephan Eggermont <stephan(a)stack.nl> > wrote: > >> TextMorph new contents: 'Text'; openInWorld > > > I don't know anything about this area, but thought it would be interesting > to dig... > > There is only one implementor of #editView which is TextMorphEditView, a > subclass of TextMorph.
