how to properly create icons

by Peter UhnÃ¡k

Hi, I've been using using ThemeIcons>>createIconMethodsFromFile:directory: method to create my own icons, however there are some reported problems https://pharo.fogbugz.com/f/cases/15277/some-icons-from-ThemeIcons-are-brok… with the code it generates. My questions are: 1) what exactly is the problem with the generated code? 2) what would then be the correct way to generate it? Glamorous (Moose) icons seem to use different format (using byte array instead of Base64), but I do not see any code that would generate those methods. Thanks, Peter

This involves learning how to do File Right How-to documentation and examples will add a lot of value to Pharo, especially for beginner and the community. I remember the old time of GNU/Linux How-to[1], there were incredibly useful for me when I learn GNU/Linux.

Loading specific commits from ConfigurationOf

by Peter UhnÃ¡k

Hi, is it possible to depend on a specific commit instead of preconfigured? For example I would like to load Roassal2, where one of the packages is Trachel, and I want to load 'Trachel-AlexandreBergel.265'. Currently I have in my ConfigurationOfMyProject ~~~~~~~~~~~~~~~~~~~~~ project: 'Roassal2' with: [ spec className: #ConfigurationOfRoassal2; versionString: #'development'; repository: 'http://smalltalkhub.com/mc/ObjectProfile/Roassal2/main/' ]; ~~~~~~~~~~~~~~~~~~~~~~ I could replace versionString: with one of the specified in ConfigurationOfRoassal2, however the newest one is too old, and #development is too new. So is it possible for me to specify what versions of the packages will be loaded? Thanks, Peter

We had a very small, and very knowledgable group, so we had lots of difficult and interesting questions and discussions. The thing that impressed them the most was the incredibly short feedback loop when doing debugger driven design, and the way you talk to your objects. We pretty much followed the slides with the exercises, having a short sample of each of the complexity reducing things we do in Pharo. Stephan

Re: [Pharo-users] DynaCASE

by Jan B.

I'm sorry for not replying for such long time. Thank you for sharing. I recommend loading via my baseline from github, which automatically loads all prerequisites including DynaCASE itself: Gofer new url: 'http://smalltalkhub.com/mc/Pharo/MetaRepoForPharo40/main'; configurationOf: 'GitFileTree'; loadDevelopment. Metacello new baseline: 'DynaCASEPetriNets'; repository: 'github://bliznjan/dynacase-petrinets/repository'; load You can take a look. As I mentioned before, it is far from complete, but I keep improving it every day so it should be usable in few weeks (petri nets model and visualisation, i.e. without simulation, much sooner).

You're right. I think by 'favorite', I meant more like 'areas you care about in general, even outside of Pharo'. For example, say you're interested in data processing in general. You can ask, "How would I go about downloading a comma-separated (CSV) file, read it into Pharo, and display a graph?" This involves learning how to do File I/O, checking to see if there's a CSV library compatible with Pharo, and checking to see what sort of graphing libraries exist (I believe one was mentioned recently on the mailing list, Roassal or something). In similar vein, you can check out XML parsers, JSON parsers, etc, etc. Or you can ask "How do I connect to a relational database? I've heard Glorp mentioned, and OpenDBX, etc, so which of these would actually work in Pharo 4?". Or, For example, maybe you care about social media APIs. You can then think, "Hey I wonder if there are any Twitter or Facebook client libraries for Pharo. Maybe there's an Open Social API ( http://en.wikipedia.org/wiki/OpenSocial ) library that I can check out." That sort of thing. > > * Write blog posts in general!

Then write posts about new user impressions of Pharo 4 (keeping in mind the usual "this is open source software" / "the devs are busy so don't be too harsh on them" sort of stuff). Or short tutorials on the various small things that you've figured out to do. (Like a cron job that fires up your Pharo image on the command line).
