Re: [Pharo-users] Pharo on Windows

Let me try asking this another way. Will someone who knows how to do Pharo development on Windows please tell me how to organize my files so that Pharo works? Obviously, leaving the files where they are in the unzipped install package does not work. How should I organize things so that Pharo can actually save an image, shut down, and then open it again? Where should I put the VM relative to the other files. How is the initial current directory chosen? I've been developing in Squeak for more than 10 years. I now about images and changes and sources and Monticello and so on. I just know nothing at all about Windoze. How can it be so hard?

Re: [Pharo-users] Left recursion in PetitParser

by Lukas Renggli

You can fix the problem by wrapping one of the parsers in the cycle with #memoize. That could be done automatically (#cycleSet finds the cycles), but I would rather refactor the grammar as it leads to extremely inefficient parsers. If you want to build complicated expression grammars (where typically left-recursion occurs) it might be useful to use the PPExpressionParser, see the class comment for an example.

Â It opens Paharo.app\Contents\Resources\Pharo.image, and complains that it can't write the corresponding Pharo.changes. if you open same image two times, it will bark about this. Also, if VM crash, it also sometimes could leave a read lock on that file. > 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.

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

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.

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!
