Custom type inference and RoelTyper
by Peter Uhnak March 14, 2016

March 14, 2016

Hi, Moose/FAMIX uses RoelTyper for type inference, how this does not seem to be maintained (last version 2013), and for my purposes is lacking. So do we have something more advanced, even at the expense of speed? Other alternative would be to either extend RoelTyper or write something custom that would be ran alongside RoelTyper. Examples of such extensions would be extracting the type from meta-annotations and the actual argument names. (e.g. if an argument is named aString, I can safely assume that it will be String). Thanks, Peter

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

Hiya, I'm told this is the right place to ask for an invitation to join Slack channel? Sincerely, Gour -- One who restrains the senses of action but whose mind dwells on sense objects certainly deludes himself and is called a pretender.

Spec: Binding widgets how to
by Offray Vladimir Luna CÃ¡rdenas Jan. 17, 2016

Jan. 17, 2016

Hi, I'm starting to migrate my grafoscopio interface from only GT to Spec-Glamorous. I have kind of a working layout as you can see: and now I want to bind the different widgets so when I select a tree node I can show/edit its title and contents. I have read the Spec documentation on how to do this [1] and the ListSelectionModel code from Spec-Examples, but seems I'm missing something. [1] http://spec.st/docs/interactions/ So, I have a GrafoscopioGUI>>initializePresenter tree whenSelectedItemChanged: [ self updateHeader ] and GrafoscopioGUI>>updateHeader "update the displayed text associated to the header" ^ nodeHeader text: tree selectedItem. but when I move on the tree, nothing happens in the header panel at the bottom. What I'm missing? Thanks, Offray
