Matching block parameter in rewrite rule
by Cyril Ferlicot D. May 8, 2020

May 8, 2020

Hi, I was wondering if it was possible with the parse tree rewriter to match a block parameter? I would like to be able, for example, to rewrite: `#() detect: #odd ifFound: [ :e | e ] ifNone: [ self toto ]` as `#() detect: #odd ifNone: [ self toto ]` But I don't know how to express this rule with the rewrite rules of Pharo. I tried multiple things such as: '`@receiver detect: `@arg1 ifFound: [ `@arg2 | `@arg2 ] ifNone: `@arg3 ' -> '`@receiver detect: `@arg1 ifNone: `@arg3' or '`@receiver detect: `@arg1 ifFound: [ :`@arg2 | `@arg2 ] ifNone: `@arg3 ' -> '`@receiver detect: `@arg1 ifNone: `@arg3' Without sucess. Is there a way to do that or is it a limitation of the rewrite syntax? -- Cyril Ferlicot https://ferlicot.fr

Issues browsing/saving a class in a package - seems like its unknown
by PAUL DEBRUICKER May 7, 2020

Hi - In Pharo 7 I'm having an issue with a particular class where if I browse it in Calypso I can see & navigate among the methods in the class. If I run some of the methods I get dnu errors for methods I can see in the class browser. If I re-save a method that has the dnu without changing anything then Calypso shows two methods in the same class with the same name. If in a playground I try a MyClass recompile Then I get an "Unknown variable..." dialog that asks me to define the class. If I highlight the MyClass in the playground and "browse" it then Calypso finds the class and opens the browser. If I fileout the class then the fileout has all the methods and two copies with the same name of the one I re-saved above. Because of these issues I cannot save the package using Monticello or iceberg. Any ideas what I can do to fix this situation? At a minimum I reckon I can fileout the bad class, delete it from the image, and file it back in, then save. Thanks Paul

Preserving Pharo Window state between sessions
by Esteban Maringolo May 6, 2020

May 6, 2020

Is there a way to preserve the window state after saving the image on quit and restarting it again? If I save my image window maximized I would like it to be maximized when starting again. Having it otherwise can be annoying when moving from different screen resolutions, because a 1920x1080 maximized window becomes a "floating" (non-maximized) window that size on a smaller screen. I guess this is controlled by the VM and not the image, but there is a way to maximize the window from the image? This way it could be a preference of some sort. Regards, Esteban A. Maringolo

Code completion in blocks (Pharo8)
by Davide Varvello May 5, 2020

May 5, 2020

Hi guys, Is there something wrong with autocomplete in blocks in Pharo 8? If I'm typing a variable in a block the autocomplete does not appear. In the following statement I'm expecting a popup after typing "eac" : 'myString' do:[:eachChar | eac TIA Davide -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
