This is an example of the nice sinergy arroud Pharo. Sean developed a multi-world feature feature. Aida tested and gave feedback. Guillermo Polito, worked with the KeyBindings. Tony took multi-word and set up custom shortcuts for chaning worlds! you see? nice! mariano On Mon, Jan 24, 2011 at 8:26 PM, Aidan Gauland <aidalgol(a)no8wireless.co.nz>wrote: > On Mon, Jan 24, 2011 at 03:09:47AM -0800, Sean P.

Re: [Pharo-users] Multiple Worlds for Pharo *stable*

by Tony Fleig

Wow. This is very cool. I have created some hotkeys (ctrl-1, ctrl-2, etc.) (using http://www.squeaksource.com/GlobalKeys.html) to switch between worlds. I usually have several unrelated projects going and this makes it very easy to manage them. Two things: 1. I noticed the taskbar was missing in the new worlds, so I evaluate the following when I create a new world: World taskbars ifEmpty: [ TaskbarMorph new openInWorld: World. (World systemWindows select: [ :each | each isCollapsed]) do: [ :wnd | wnd restore; minimize ]]] 2. In looking into the TaskbarMorph, I stumbled across the Project class. It seems like there might be some overlap with multiple worlds there. Any comment? Regards, TF On Mon, Jan 24, 2011 at 3:09 AM, Sean P.

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.

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?

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.

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. Andrew From: pharo-users-bounces(a)lists.gforge.inria.fr [mailto:pharo-users-bounces@lists.gforge.inria.fr] On Behalf Of Anindya Haldar Sent: 21 January 2011 07:00 To: A friendly place where any question about pharo is welcome Subject: Re: [Pharo-users] Where do I find KeyedSet? I also noticed that the TestCase >> assert: method has changed in Pharo 1.1.1 that it does **not** take a booleanOrBlock anymore, it always expects a boolean. This would make all tests using the assert: [... a block returning boolean here ...] style fail in Pharo 1.1.1. I am not sure this change is a deliberate design decision or a bug. Whatever it is, those tests will also have to be changed as part of the TestMock port for Pharo 1.1.1 in order for the suite to pass.

I am probably late to the discussions here, although as the author of the TestMock package I can assert that the unit tests for TestMock pass in my pharo 1.0 environment. I have not tried the Pharo 1.1.1; and from the discussions it looks like the package fails there because KeyedSet has been deprecated. I will take a note of this, and will look forward to add a fix and publish a new version once I upgrade my Pharo image. Thanks a lot to everyone chiming in.

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!
