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.

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

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

Re: [Pharo-users] Pharo on Windows

by Tony Fleig

Just to add to what Andrew experienced: I am a relatively experienced Pharo user on Linux and OSX -- or at least I know about the VM and image and change files. I recently decided to test the TFLogin package on Windows so I installed Pharo on Windows using the One-Click image. I had an experience similar to Andrew's. It may have been easier for me to diagnose and fix the problems as I am more experienced with Pharo and have programmed on Windows for years, but... I think Pharo should install and run without problems the way any quality Windows does. I did nothing during the installation that I was not prompted to do (such as deciding where to place the zip file and where to unpack it) and yet Pharo would not start the first time I clicked on the shortcut. Pharo is great, but it should install and run without problems for newcomers on the most popular OS platform out there. Granted, programmers are more likely to be able to resolve the problems, but it doesn't inspire confidence when a product doesn't work immediately after installation. If I were at all uncertain about whether I wanted to try Pharo, failure on first startup might be enough to cause me to uninstall it without further investigation. I know resources are tight, but perhaps a little more attention should be given to the new user's first-time experience on Windows.

Re: [Pharo-users] Pharo on Windows

by Miguel CobÃ¡

Pharo experience is conformed of three things: VM Image sources file When you start the vm, it must run a image. When a image is ran, it searches for a sources file and as the development you do goes on, a changes files is generated. Now, if you downloaded the Pharo One-Click, this is a package of the several components that conforms Pharo, arranged in a given directory tree structure. Most surely, the paths and relative paths of the components is important. So isn't wise to get out the image out of this directory tree without the sources and the changes file. If the installation associated the .image files to the Squeak.exe vm, then double click on a image that is sitting along a source file should start the image without problems. But if you only have the image (associated with a VM) then on start the image will whine about the sources file. If you want to have the image everywhere in your machine the best is to download the vm separately and install it on your machine. Then download a Pharo Core image and populate it with the code you're interested or extract from the OneClick the image *and* the sources and put it on a folder (a changes will be created eventually).

Pharo on Windows

by Andrew Black

I just started using Pharo on windows for the first time. First, I should say that I'm really impressed. Pharo seems much more solid than when I last tried it. I programmed all day without getting a walkback! All of the tools "just worked". Well done! It's a lot of work creating a solid user experience, but you have done it. Now I have some Windows-specific questions. I'm a real windows newbi, so please be patient. After I downloaded Pharo.app, I dragged the whole directory to a convenient place, and tried to launch the Pharo.lnk file, just like the readme file says. But there is no such file visible in windows explorer (even though I have "don't show extensions for known file types" box unchecked. The file shows up as Pharo. Anyway, I figured that it was really Pharo.lnk (Cygwin tells the truth) and double-clicked on it. This brings up an alert that says C:\Users\<username>\Desktop\OneClick.app\Contents\Windows\Squeak.exe the specified path does not exist. Is this because I moved the downloaded package? Shouldn't the symlink be relative? Anyway, I looked in ...\ Contents\Windows\, double-clicked on Squeak.exe, and everything started up just fine. I worked all day, and saved my image a few times using the Save menu on the desktop. Each time, I get the usual confirmatory dialog in the Transcript. Overnight, my machine shut down. Today, I relaunch Squeak.exe, and of course I get the virgin image! Where is the image that I've been using? The Windows "search this computer" tool can't find it! What about my package cache? Eventually I find everything in Pharo.app\Contents\Resources, but not until I've had a few moments of panic! Questions: Is this the appropriate behaviour on Windows, or was there a user error on my part? Is it OK to move my image somewhere else? How can I change the current directory for Pharo on Windows? OK, so now that I've found my image file, how to I re-launch it? I double-clicked on the .image file, and I got a dialog saying that Windows didn't know what program to use to open it. Fair enough. So I told it to use Squeak.exe. Pharo launches, and I get: "Error: invalid utf8 input detected". It's treating the image as if it were a source file: it has opened a MultiByteFileSTream on it. That's not right. How do I re-launch my Pharo image? Andrew

Infinite loop is not stopped by Cmd+.

Hi List, Recently I had a bug causing an infinite loop, which in turn hanged the image. I thought that Cmd+. would allow me to stop this, but this is not the case.

Re: [Pharo-users] Pharo and network

by Michael Roberts

yes... depending on your OS and version of Pharo, 127.0.0.1 does not always work as the destination from your client to your server socket. Did Olivier's code snippet work? try using netcat or lsof (unix) to see and interact with the state of your sockets. There is also a SocketStream implementation (somewhere) that hides a lot of this. cheers, Mike On Fri, Jan 14, 2011 at 11:35 PM, Olivier Auverlot <olivier.auverlot(a)gmail.com> wrote: > Hi Adrien, > > Could you try : > > | s | > s := Socket new. > s connectTo: (NetNameResolver addressForName: 'localhost') port: 12345. > > Best regards > Olivier ;-) > www.auverlot.fr > > Hello, > > I read these documents: > http://book.pharo-project.org/book/networking/Socket > http://wiki.squeak.org/squeak/325 > > but I still don't get what I want with pharo. > > Here is the idea: I want a socket to listen a port while pharo is launched > as a deamon. > > I tried to test the sockets with this idea: > - creation of two sockets in two workspaces > - server: > > | server st | > st := String new. > server := Socket newTCP. > server listenOn: 12345 backlogSize: 4. > server receiveDataInto: st > > - client: > > | s | > s connectTo: ('127.0.0.1' asByteArray asSocketAddress) port: 12345. > s sendData: 'Hello' > > - the connectTo:port: fails, and I don't understand why > > So I have no idea ... > > Adrien. > >

I know we are very few, but what about this idea, instead of just deleting a class we may adopt these simple rules: 1 - If deleting a class add the deleted class name somewhere (in a method?) 2 - If renaming a class, make the class to know its previous names like #previousNames (Norberto Manzanos implemented this for his own package management and I think is a great idea) doesn't require tools, just some consensus and maybe a modified #deleteClass to enforce this "policy" it sounds feasible for you? what do you think?

TDD facilities: missing ctrl+t

by Alex Schenkman

Hi list, I've installed the TDD-Facilities package. Pressing ctrl+t, or ctrl+r does not run the test, :-( I'm pressing it while editing a test method, in the default browser of a Pharo-1.1.1-OneClick image. Any clues on what I might be missing? Thanks again!

Where do I find KeyedSet?

by Alex Schenkman

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!
