Trait composition on runtime

by Norbert Hartl

Does pharo support runtime trait composition or does it only work on class definition time. I mean something like anObject addTrait: MySpecialCapability anObject removeTrait: MySpecialCapability Norbert

RFB is locking up the image in Pharo 2 without my code if the RFBServer is running. I've put an image up here: https://dl.dropboxusercontent.com/u/4460862/pharo2RFB.zip that will freeze when the the save is performed. The save completes. Its after that that the freeze happens >> On 08/21/2013 09:53 AM, Paul DeBruicker wrote: >>> I forgot to mention that when I debug >>> >>> Smalltalk snapshot: true andQuit: false >>> >>> it freezes in the snapshotPrimitive >>> >>> >>> >>> -- >>> View this message in context: http://forum.world.st/saving-a-pharo-20619-image-that-has-my-code-and-RFB-s… >>> Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com. >>> >> >> > >

The future of SqueakSource

by Andrei Vasile Chis

Hi all, We will shut down the SqueakSource image at the end of next week (30 August 2013). The current system will be replaced by a simple view of the file system containing just the publicly visible projects. As meta-data, each project will have it's overview page attached (showing the licence and its author). Please forward this email to other mailing lists. Cheers, The SCG Team

Seems like it only freezes when the RFB server is running.

saving a pharo 20619 image that has my code and RFB server causes 100% cpu utilization

by Paul DeBruicker

If I choose 'save' or 'save as' the image locks up. It only happens with my code and the RFB server loaded. In a pharo 2 + rfb image things work fine. In a pharo 2 + my code image things work fine. 'Save and quit' then re-opening the image works fine. What can I do to diagnose what is happening? Thanks Paul

Putting a dot after the @ means that you want to match statements. So '``@.some size' cannot match: 'arg1 size'. > Does not match with: > insideABlock: arg1 part2: arg2 > |temp1 temp3| > [arg1 size]. > temp1 := arg2 + 3. > ^arg2 Then even if you remove the extra dots, the rule won't match the method you give. This is because this method has no statements matching '``@some size' (even if it has a block that has a statement that can). So here is a rule that can match your method: `a: `aa `b: `bb | `@temps | `@.stms1. [ `@rcv size ]. `@.stms2. > After looking while I realize that is not matching with > part1: arg1 part2: arg2 > |temp1 temp2 temp3| > arg1 size. > temp1 := arg2 + 3. > ^arg2 This one however can be matched by your rule (without the extra dots). I think that you should try to parse expressions instead of full methods (RBParseTreeSearcher>>#matches:do: instead of RBParseTreeSearcher>>#matchesMethod:do:). You could just try to match '`@rcv size': it would succeed in both methods. > > Until I understand: > ``@.some size ``@.more. > This should mean: anything that sends the message size, doesn't matter if we have something before or after, I think that this expression should match both cases. > > But maybe I'm missunderstanding the patterns (again). It should work like that (modulo bugs) ` denotes a metavariable adding @ means you're looking for a list of elements ex: `receiver `@msg: `@arg matches every message adding a . means you're looking for a statement (or a list of statement if you combine it with @) adding # means you're looking for a literal adding another ` means that the pattern will be searched recursively in each subexpressions even if the top one already matched it sometimes leads to infinite loops, but I don't remember exactly when ex: in 'foo bar bar' : if you search for '`rcv bar' you'll find one match ('foo bar bar') if you search for '``rcv bar' you'll find two matches ('foo bar' and 'foo bar bar'). and I think it's all > > Any help with this will be really welcome! > >

Rw engine and Patterns for searching

by Gisela Decuzzi

Hello, I'm trying to understand how to define a correct pattern and I'm lost with the cases where I use a method pattern and the desired code is inside a block. In the case where we search (methods) with metavariables and the code is inside a block. An Example: This pattern `a: `aa `b: `bb | `@temps | ``@.Stats. ``@.some size ``@.more. ``@.Stats2. Does not match with: insideABlock: arg1 part2: arg2 |temp1 temp3| [arg1 size]. temp1 := arg2 + 3. ^arg2 After looking while I realize that is not matching with part1: arg1 part2: arg2 |temp1 temp2 temp3| arg1 size. temp1 := arg2 + 3. ^arg2 Until I understand: ``@.some size ``@.more. This should mean: anything that sends the message size, doesn't matter if we have something before or after, I think that this expression should match both cases. But maybe I'm missunderstanding the patterns (again). Any help with this will be really welcome!
