February 2015 - Pharo-users

Re: [Pharo-users] Published some old games ...

by Laura Risani

I'm glad you like them :). It was fun to develop them . I can play Tetris for a long time, but i can't survive on the EaterGame for more than 40'. @Nacho Thank you for your feedback. About the Eater, perhaps in the future i make some additions, but is fully functional now (when you complete a level there is implemented an increase on monsters aggressiveness). Visual subjective enhancements could be added, but i'm satisfied with its minimalist look. I add the writing to the corresponding section of my todo list.

Re: [Pharo-users] Spotter: Browse Impementors?

by Tudor Girba

Hi, As Juraj said, you can Cmd+Shift+ArrowRight to dive in the category and using the preview you can browse the code. If you want the MessageBrowser, there is no way to get it by default. Laura also asked for this feature before, so I listed below a crude code to add a processor that finds selectors instead of implementors. Just install this method and then start spotting. Let us know if this is better: GTSpotter>>spotterSelectorsFor: aStep <spotterOrder: 0> | processor | processor := aStep listProcessor. processor title: 'Selectors'; filter: [ :originalQuery :stream | |query selectors | query := originalQuery trimBoth asLowercase. query isEmpty ifFalse: [ selectors := Set new. SystemNavigation default allBehaviorsDo: [:class | class selectorsDo:[ :selector | ((selectors includes: selector) not and: [ selector beginsWith: query ]) ifTrue: [ selectors add: selector. selectors size > 5 ifFalse: [ stream addObject: selector inProcessor: processor ]]]]. selectors ] ]; actLogic: [ :each | self systemNavigation browseAllImplementorsOf: each ] Cheers, Doru On Tue, Feb 10, 2015 at 9:24 PM, Sean P.

Sven made a ZnReadEvalPrintDelegate that you can easily hook in to execute a smalltalk snippet (if your host is secured). The good thing about Sebastians approach is that whenever the OS is shut down it is called with SIGTERM from the OS. So should fit nicely with orchestration of the machine.

Great. This is cool. Why this can't be part of the stock vm/image? Regards! Esteban A.

Re: [Pharo-users] Spotter: Browse Impementors?

by Juraj Kubelka

You can dive-in using cmd+shift+right-arrow in Spotter and follow observation of those implementors. Preview is available by cmd+p. So basically you open in a browser only one specific method. Do you need to open it in Implementors/Senders Browser? If yes, can you describe your use case, please? Thanks. Cheers, Juraj > 10. 2. 2015 v 16:40, Sean P.

Re: [Pharo-users] Nautilus groups

by stepharo

having a simpler way to express here is my project would be good. For now the way to add a group is too complex. I would like to click on package and add it to a favorite list that is on the top I would love to get a group containing the class that were loaded (or not in the system). because often I load a configuration and I have no clue what have been loaded.

Spotter: Browse Impementors?

by Sean P. DeNigris

Maybe I'm missing something obvious, but if I zero in on a message name in spotter, can I open a browser on all implementors, or only browse one specific method? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Spotter-Browse-Impementors-tp4805013.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
