Re: [Pharo-users] Is RBClassNotReferencedRule ~200x slower in Pharo 4 vs Pharo 3 ?

by Yuriy Tymchuk

I need to double check it, for now I cannot access the issue tracker (probably local internet issues). As far as I remember, the problem was that SmallLint rules where checking contexts and not classes and methods. I.e. you had to create a context, set itâs âselected" class or method, pass it into the rule and then rule would take out class or method out of the context and check them. In my humble opinions this is 1) pain, 2) a bit confuting that #chackClass: method accepts context and not a class. But I guess at some point there was some caching happening during the check in a certain rules, and now itâs not there. What I was suggesting is to either define a context attribute for all rules, or even better, define a hierarchy of rules that besides the entity to check accept the context that is needed for the check, as not avery rule requires a context. By default it can be a live context of whale system, but on demand we can create a snapshot of a context (with caches) and pass it to different rules several times. Sadly I never managed to finish implementing it, itâs still in my todo list.

This is how it works in Python. After evaluating the first line the variable /a/ becomes a list, so in the second line only list methods are shown. <http://forum.world.st/file/n4844128/screenshot_150819-191603.png> -- View this message in context: http://forum.world.st/Customised-auto-completion-to-give-priority-to-specif… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Customised auto-completion to give priority to specific packages

by Attila Magyar

It would be really nice to have real message completion in the debugger/inspector/workspace where the types of the variables are known. For example, when I'm debugging a method and an instance variable is already initialized to a String, then the auto completion could show me only the messages associated to a Strings instead of showing everything in the image. -- View this message in context: http://forum.world.st/Customised-auto-completion-to-give-priority-to-specif… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Customised auto-completion to give priority to specific packages

by webwarrior

I have interest in customized auto-completion. It would be also cool if it was possible to assign customized auto-completion to some instvars/arguments (for example based on knowlege about what their type is expected to be). -- View this message in context: http://forum.world.st/Customised-auto-completion-to-give-priority-to-specif… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

SmaCC 2.0.5 released

by Thierry Goubier

Hi All, I have released SmaCC 2.0.5, aligned on the main SmaCC[1] with a small fix on the Java parser, a few additional parsers (Cucumber), the addition of the Javascript parser, and continuous improvements on the performance and source code coverage of SmaCC generated parsers (with many thanks to John Brant and Don Roberts). The project is available on github[2] [1] http://www.refactoryworkers.com/SmaCC.html [2] https://github.com/ThierryGoubier/SmaCC This release is targeted at Pharo4. All parsers should work on Pharo 5, but the GUI doesn't work. Most parsers come with full AST generation and a dedicated visitor for each, and support for native language refactoring. To retrieve a specific parser, please use Metacello with the following script: Metacello new baseline: 'SmaCC'; repository: 'github://ThierryGoubier/SmaCC:v2.0.5'; load: 'SmaCC-Javascript' (SmaCC-Python, SmaCC-Java, SmaCC-Cucumber, etc...) On Pharo4 only, to retrieve the full set (gui and tests), please use Metacello with the following expressions: Metacello new baseline: 'SmaCC'; repository: 'github://ThierryGoubier/SmaCC:v2.0.5'; load Regards, Thierry

Making a Rubric text morph movable

by Stephan Eggermont

We have a Morph containing a RubTextFieldMorph that we want to be able to drag around. At the same time, we want selection extension with the mouse to work. That feels ok when the dragging can only be initiated when the text field has no keyboard focus. The way we've made that work feels somewhat clumsy. What would be a better way? The containing morph has a default mouseDownPriority of 10 MindmapNode>>initialize super initialize. self addMorph: ( (MindmapTextField on: self) withGhostText: self defaultTitle; autoAccept: true; bounds: (self bounds); yourself). prio := 10. When it is clicked, the prio is set to 0 MindmapNode>>click: evt submorphs first takeKeyboardFocus. prio := 0 The text field is subclassed RubTextFieldMorph subclass: #MindmapTextField and overrides whenFocusLost: MindmapTextFieldwhenLostForcus: anAnnouncement owner resetPrio. super whenLostForcus: anAnnouncement MindmapNode>>resetPrio prio := 10 Noah & Stephan

Re: [Pharo-users] Notepad type window to keep text notes?

by Dimitris Chloupis

you can also use Playground and type your text inside a comment. Alternatively you can use the help tools as documentation if that is your goal or play with the GLMRubricExample subclasses. Pillar is also great if you want well formated documentation and it exports in both html and pdf format (you will need Latex for pdf generation). Pillar syntax is super simple and you can use your favorite editor. On Wed, Aug 19, 2015 at 8:53 AM H.

The original morphic layout (the one used in Self[1]) is a constraint-based layout. I'm not sure your average developper understands or likes a constraint-based layout and, if he has the hand on the development of the GUI, he tends to replace it with procedural approaches (with layout frames, margins, etc...), as is the MVC layout engine in VW. Still, Apple managed to introduce the Cassowary[2] layout engine in OS X and iOS [3]. It could be valuable to have a look into how X Code on Mac gives a GUI for specifying layout constraints.
