Left recursion in PetitParser

by Andrew Black

I have a PetitParser question. A small part of my grammar is like this: expression := constant / namedSend / ... namedSend := receiver dot namedMessage / ... receiver := expression This is of course left-recursive. I believed the "all the rest is magic" blurb and just went ahead and wrote it as given above. I get an infinite recursion when I run the parser. I know how to left-factor the grammar by hand. But should I have to? How powerful is thy magic, Lukas? Andrew

I tried that. The effect is the same as double-clicking the image file: it starts up the VM, which then tries to read the image as a UTF8 file, and gives me a walkback. If I just launch the VM, it does NOT ask me which image to open. It opens Paharo.app\Contents\Resources\Pharo.image, and complains that it can't write the corresponding Pharo.changes. This is true even though I have moved the VM into another place on my disk (along with the sources and the image + changes files that I want it to open). There is nothing wrong with the image file itself, btw. I copied it to my Mac on a memory stick, and was able to launch it and work in it for most of yesterday. I'm at my wits end with this. Am I the first person to try the COG VM on Windoze? Andrew

Error in logging chapter of "Pharo collaborActive Book"

by Panu Suominen

I was not sure if this is the right list. There is example like this in logging chapter of the Pharo book: Gofer new project: 'Logging'; package: 'ProcessSpecific'; package: 'Logging'; load It does not work. Maybe it should be: Gofer new squeaksource: 'Logging'; package: 'ProcessSpecific'; package: 'Logging'; load -- Panu

Re: [Pharo-users] Where do I find KeyedSet?

by Andrew Black

There was a good reason for the BooleanOrBlock convention, IIRC. I wonder what it was? Something about when the assert fails, you get more information in the debugger if you use a block. Can anyone else remember the details.

Hi List, I'm trying to use the TestMock package in a Pharo-1.1.1-OneClick image, and it uses KeyedSet. Where can I find this class? Is there any tool to lookup which package in SqueakSource contains a specific class? Thanks in advance!

Pharo on Windows

by Torsten Bergmann

Looks like you use the "Pharo one click image" which is multiplatform. Why dont you use the Pharo installer for Windows which I created. - the download is smaller (you dont get the Linux/Max VMs) - it is better integrated into Windows You can find it when you scroll down at: http://pharo-project.org/pharo-download Here is the direct link: http://gforge.inria.fr/frs/download.php/27305/setup_pharo1.1-11411-release1… Bye Torsten http://astares.blogspot.com -- NEU: FreePhone - kostenlos mobil telefonieren und surfen!

soft write barrier

by Norbert Hartl

I'm thinking about tracking changes to objects. I had a look at WriteBarrier on squeaksource. My goal would be to have something more soft that does not need to track class shape changes and most of the system notifications, just the state of an object. A second goal is to avoid having to use primitives but that shouldn't be too hard. The objects will be materialized via http and I want to have a good way to track those changes. I can think of some approaches but wanted to ask for the clever ones :) What possibilities do you see to achieve this? thanks, Norbert
