Using GTSpotter how do I find an implementor of #accept ?
by Paul DeBruicker Feb. 20, 2016

Feb. 20, 2016

when I hit shift+enter and type 'accept' I get things that are not #accept, e.g. #accept: and AbstractAcceptor. If I add a space after accept it doesn't help. What do I not understand? Thanks Paul

Customised auto-completion to give priority to specific packages
by Dimitris Chloupis Feb. 20, 2016

Feb. 20, 2016

As a next step for my project Ephestos , I want to mess with auto-completion. My goal is for auto completion to give priority to the Ephestos packages. This way the Ephestos users will get recommended first auto completion of Ephestos classes and methods, I will then add a line to separate those from the rest of Pharo recommendations. I could customise this further to accomodate for any package inside pharo thus making the autocompletion prioritise your packages and classes/methods. Is there any interest for something like that ? If there is then I could make it into a separate Pharo project and make it easy to install via Package Browser (Pharo 5 configuration browser) . If there is no interest then I can keep it as part of my project and not do the extra work for separating the code. I also welcome any advice and recommendation on how to achieve this by people who already hacked auto completion. I already study the NECompletion package so I have a general idea but so far have not figure out how to priorotise recommendations.

World lastKeystroke and openInWorld: aPasteUpMorph
by Markus Schlager Feb. 20, 2016

Feb. 20, 2016

Hi, I'm using pharo to teach smalltalk as first 'real' programming language at school. With older versions of pharo I was glad that my pupils could track keystrokes so easily by evaluating World lastKeystroke. With Pharo3.0/4.0 this only returns '<down>' independently of any keys I'm typing. f := PasteUpMorph new openInWorld. f takeKeyBoardFocus. f lastKeystroke. Is returning the empty string. Hence, my question: Is lastKeystroke broken, or how is it meant to be used now? Second problem: In older versions of pharo this would work: f := PasteUpMorph new openInWorld. b := EllipseMorph new. b openInWorld: f. But with Pharo 3.0/4.0 the last line raises an error: MessageNotUnderstood: PasteUpMorph>>startSteppingSubmorphsOf With f := WorldMorph new openInWorld. b := EllipseMorph new. b openInWorld: f. pharo freezes. So: How is openInWorld: meant to be used? Markus

Halo Menu On Spec Tree Node
by Craig Johnson Jan. 6, 2016

Jan. 6, 2016

Hi All, I had an issue - when I opened a Halo on a Spec tree node in the UI and select the menu Icon, I got a DNU message. However if I selected a normal Morph, the menu Icon worked fine. I'm using Pharo 4.0 released version. Fixed this by changing TreeModel>>iconFor to: iconFor: aNode ^ iconBlock value cull: aNode content*s* cull: aNode Craig

Fossil and Filetree
by Hilaire Dec. 25, 2015

Dec. 25, 2015

Hi, I have been trying Fossil with Filetree, and I was rather please by the mutuals use of these tools. So I may share a few feedbacks. Fossil[1] itself is a software to manage source code development. It is very simple to install and data is saved in a single sqlite database. It comes with source code management, bug tracker, web interface, wiki and timeline tools. I was a bit afraid by the filetree atomic commit (one file per method) to manage it without much headache with file based VCS. However fossil comes with a nice command: 'fossil addremove' to add/remove the changed files in the repo. So it went fine. So all in all, it is pretty nice if one want to move to a private souce code management system with very little requirement.

[ANN] Multiple Desktop support for Pharo 5
by Torsten Bergmann Dec. 21, 2015

Dec. 21, 2015

Julien Delplanque provided this week a goodie to switch between "desktops" - but his initial solution was more or less hiding windows and not really switching between real Pharo worlds/desktops. I gave him some tips what could be done on the pharo-user list. Havent heard from him afterwards. Now I was able to spend a few hours on this topic myself and implemented a full multiple desktop solution myself. This works in Pharo 5 only (currently) and requires latest VM (at least on Windows) from files.pharo.org to get the keyboard shortcuts right. To try: Gofer new smalltalkhubUser: 'TorstenBergmann' project: 'DesktopManager'; configuration; loadDevelopment. The goodie has some nice features like keyboard navigation, world menu integration and even a custom spotter with preview of the desktops. Quick start: =========== - evaluate the above expression in a Pharo 5 image - check the world menu "Desktop" - you can press CTRL + D and then CTRL + A (= Desktop Add) to add a new desktop - you can press CTRL + D and then CTRL + D (= Desktop Desktop) to open the overview - you can press CTRL + D and then CTRL + P (= Desktop Previous) to navigate to the previous desktop - you can press CTRL + D and then CTRL + N (= Desktop Next) to navigate to the next desktop The code is hopefully a good example on how to build a custom spotter, shortcuts, inspector extensions, ... Additionally all this is described in a new article including screenshots and a guide on how to use this new goodie: https://medium.com/@astares/multiple-desktops-for-pharo-5cbc46f3179f Actually the article took more time to write than coding but I hope it helps explaining Pharo and why it is a power tool. Project is on http://www.smalltalkhub.com/#!/~TorstenBergmann/DesktopManager Article and code is still subject to change. Have fun T.

More fun with Morphic: 1st iteration of a Mindmapping tool
by Stephan Eggermont Nov. 19, 2015

Nov. 19, 2015

The past three days, Noah Domingo (15) and I have been working on a new Morphic example. We have build a first iteration of a Mindmapping tool. Noah shows it in: https://vimeo.com/136943448 We would be interested in some design critique. The way the Rubric text field is embedded in the MindmapNode is not so clean. The code can be loaded by Gofer it smalltalkhubUser: 'StephanEggermont' project: 'Mindmap'; package: 'Mindmap'; load

I have played with the code, and started writing some code which manipulates the Google services. It is really powerful. Also, Richard has developed a slick way of dealing with OAuth when running a client app. This is great!

Smalltalk Meetup in ZÃ¼rich: Nov 10, 2015
by Joachim Tuchel Nov. 8, 2015

Nov. 8, 2015

Dear Smalltalk fans in the ZÃ¼rich area, if you happen to have a free slot in your calendars for November 10th, 2015 (I guess 19:30 will be a good time to start), I have something for you: We would like to get together with Smalltalkers of all flavors to chat about the latest news, tools and projects at a restaurant near Bahnhof HardbrÃ¼cke, like we did several times in 2014. I think it's time to catch up and I know Peter, Philippe and Michal feel the same. So please send me a note and let me know if you'd like to join us for an evening of Smalltalk... I'll reserve a table and let you know exactly where we meet. If you are not in the ZÃ¼rich area but don't mind travelling to meet us, feel free to come! Hope to see you soon in ZÃ¼rich! Joachim
