Re: [Pharo-users] Pharo on Windows

by Stuart Herring

I'm using Pharo with Cog on Windows without a problem. However, I have never used the One Click distribution. I just download the regular Pharo image and Cog separately, and use "open with.." on the context menu of the image file to find the Cog VM. There was nothing special required that's not required with every other Windows program. (Normally I'd just double click, but I have the pre-Cog Squeak VM associated with .image at the moment) On Sat, Jan 22, 2011 at 3:49 AM, Andrew Black <t-ablack(a)microsoft.com> wrote: > Let me try asking this another way.

Re: [Pharo-users] Pharo on Windows

by Andrew Black

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?

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.

Re: [Pharo-users] Left recursion in PetitParser

by Lukas Renggli

> I know how to left-factor the grammar by hand.Â But should I have to?Â How > powerful is thy magic, Lukas? There is no magic. 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.
