Ideas for beginners, for Sprints etc: * Adding class comments/documentation, as mentioned, is a fantastic idea. Maybe we can provide some code snippets, that will bring up a list of classes with missing comments (or with too-short comments, less than X characters). People can coordinate (on IRC, or via something like EtherPad) on who's working on which classes. * Not related to core Pharo code itself, but still very helpful: Test various libraries for compatibility with Pharo 4.0. Pick your favorite pharo-related project or library off of SmalltalkHub (or SqueakSource, etc), try to load it into Pharo 4. Run the unit tests. Fix stuff until it loads fine in 4.0.Try and use the library in a simple demo project. Best yet, write a blog post about it. The success of Pharo largely depends on the success of its ecosystem of libraries and projects. * Benchmark things. Which JSON library (of the several available) is faster at parsing large json objects in Pharo 4? That sort of thing. * Write blog posts in general! Write tutorials and walkthroughs on how to use some of the new 4.0 features. Do programming puzzles / interview questions and post about em. Share tips on how you theme and customize your Pharo images, which tools you use most, and so on. * As mentioned before, at least browse the open 4.0 issues on the pharo FogBugz. Try to think about how you'd go about discovering how to solve them. You'll learn a lot about the system. Also, once the issues are fixed, you can help test and confirm the fix (if you can figure out the 'how to reproduce' steps). Follow the 'to reproduce' steps to make sure you reproduce the error/issue. Then load the slice containing the fix from the pharo inbox repo, and redo the steps again to make sure it was fixed.

Re: [Pharo-users] Tabs in Playground ?

by Alexandre Bergel

Hi Cyril, Maybe it is sufficient for you to work with an inspector. For example, define the method gtInspectorExampleIn: composite <gtInspectorPresentationOrder: 30> ^ composite table title: 'Example'; display: [ { #one -> 'hello' . #two -> 'world'} ]; column: 'Key' evaluated: #key; column: 'Value' evaluated: [ :each | each value printString ]; send: #value in the class SmallInteger and doit: 10 inspect Cheers, Alexandre > On Apr 3, 2015, at 9:24 AM, Cyril Ferlicot <cyril.ferlicot(a)gmail.com> wrote: > > ââHi ! > Is it possible to have multiple tabs on the playground ?

Re: [Pharo-users] Tabs in Playground ?

by kilon alios

No its not possible. There is a workaround which is kinda ironic. You can use the old workspace as a container for multiple Playgrounds, each tab will contain a new playground. So issues the command Workspace open in a plaground and then go to the righ menu (down arrow) , choose window group and drag your playground to the tabs bar. Of course you can add as many playgrounds as you want , each in its own tab. Works like a charm :) I am a huge fan of window groups and I heavily use them :) On Fri, Apr 3, 2015 at 3:24 PM, Cyril Ferlicot <cyril.ferlicot(a)gmail.com> wrote: > ââHi ! > Is it possible to have multiple tabs on the playground ?

But if a customer has an existing database there is nothing to think about. I only need a few things out of the database. So to me it appears I give it a try with pharo. If it does not succeed within a certain time I might be better off doing the database part with another language providing a HTTP interface which I can access from pharo.
