I agree, I like PharoLauncher. It works very well. Sean, you didn't add a "deploy this image on Digital Ocean" command yet? Stephan

Re: [Pharo-dev] update of pharo by example?

by stepharo

thanks dmitri. Indeed I would love to have people helping more. Damien and me are flooded by work right now. If you start here are some suggestions: - start by the end chapters (there are easier because less dependent) - I started to remove interaction details that will make the book obsolete fast. - I use Pharo and not Smalltalk most of the time. - I control reference on squeak because this is a pharo book - I'm redoing the diagram. - I was stuck in the Object Model (because the code changed and I should design an example that will be stable over time and not based on the system). Now the object model is not only presenting it but it is also teaching fundamental aspects of oop (that unfortunately many people got wrong. What would be good - you can start reading what we did already - ideally I would like to extend pillar so that we can execute the code snippets automatically and check that they are correct oscar had this excellent idea for PBE. if you start let us know :) We are working on a Mooc about Pharo so we want to have Pharo by Example fully updated.

Re: [Pharo-dev] update of pharo by example?

by kilon alios

the main repo is here https://github.com/SquareBracketAssociates/UpdatedPharoByExample There is a link for how to contribute in the README. I was added as a contributor, all the above projects are inside an organisation so once you added as a contributor to this orgainsation you can contribute directly to all books . Pull requests make more sense when you create forks and make your own versions that go to a diffirent direction than the original repo. When all you want is to contribute then becoming a contributor makes more sense because its more straightforward for you and the original authors.

Re: [Pharo-dev] Color arithmetical operations are broken

Do we need to do something for Pharo 4?

I'd really like to do away with the "Local" template folder and on the original remote template indicate that it is cached locally - but I haven't found the time to experiment. cheers -ben On Sat, Mar 21, 2015 at 4:33 AM, Sean P.

Re: [Pharo-dev] Pharo 4.0 Download options

by Dmitri Zagidulin

Why not let new users try running their code on the unstable in-progress Pharo version? I mean, developers generally know the deal. You either use an older Stable version, or if you can tolerate instability, you develop against a moving target (Pharo 4, in this case) so that it's easier to port, when it's released. This is fairly standard stuff, right? Sean is right - why offer a download link at all (on the Pharo download page) if it's not for new users? Experienced Pharoers don't use it anyway. If, for some reason, you believe strongly against letting newbies play with Pharo 4 at all, why provide a download link at all? This reminds me of street signs in Boston, USA :) (Or rather, the lack of them, on many streets. And locals say "well, this is Boston, if you don't know where you're going, you probably shouldn't be here." I'm not even kidding! And I think, you guys are missing the point of street signs...)

Re: [Pharo-dev] update of pharo by example?

by Dmitri Zagidulin

What's the workflow, to contribute to Updated Pharo By Example? Should people just make PRs against that repo? Looking over some of the other SquareBracketAssociates repos, there seems to be a repository-based workflow? - https://github.com/SquareBracketAssociates/PharoInProgress for work in progress chapters - https://github.com/SquareBracketAssociates/PharoReadyForReviews for chapters ready for reviews? Does that mean that one makes PRs to the main UPBE repo after they get reviews? Or is this a previous / obsolete workflow?
