funny idea Symbol vs. Selector
by stephane ducasse May 14, 2015

May 14, 2015

Hi guys I'm thinking aloud... I was wondering if we could not take advantage of a new class: Selector. MethodDict would only contain selectors and not symbols. I remember that I talked about that with hernan. Stef

Hi, I want to use http://www.squeaksource.com/Z3950 Following install instructions, I've dowloaded yaz sources (I've tried 4.1.2 and 3.0.52) as it seems there's no binary for OSX, ./configure && make && make install.

Help (perfect for newcomers) migrating a technical FAQ
by Mariano Martinez Peck April 9, 2011

April 9, 2011

Hi folks. I had a good idea and and it perfect for someone that wants to help and don't know how. It is not the most entertained task, but I promise you will learn a lot. Mostly, if you are newcomer. The idea is basically to migrate the FAQ that is here: http://scg.unibe.ch/wiki/faq/pharofaq to a new section in the collaborative Pharo book: http://book.pharo-project.org/ So....any takers ? Let us know so that we generate a new user in the Book The idea is also to check whether what is says is still correct for pharo or if it needs an update. Or even how to improve it (from the view of a newcomer). Thanks Mariano

Left recursion in PetitParser
by Andrew Black Jan. 31, 2011

Jan. 31, 2011

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

Scrolling in a Morphic game
by Aidan Gauland Jan. 29, 2011

Jan. 29, 2011

Hello, I am developing a game in Morphic -- nothing serious; just a spare time project -- and I have come to a tricky part: the viewport. So far, I have just put my Morphs in a PasteUpMorph for testing, but now I need to have a viewport to a (game) world that is larger than the screen, and be able to pan/scroll the view around the world. I really have no idea how I could or should do this in Morphic. Maybe subclass PasteUpMorph and override #drawSubmorphs? Can anyone here offer any advice with this? Regards, Aidan

Screencast proposition: Watch someone read code.
by Helene Bilbo Jan. 29, 2011

Jan. 29, 2011

Hi, i have a proposition for a Pharo-Screencast: I would love to look over someoneâs shoulder while she/he is *reading* code. A possible plot would be to download something from squeaksource and then trying to make sense out of it - and talking while doing so. (It would also be good to see all the relevant functions of the browser in action). Background: While i have read some books now (blue book, pharo by example, seaside by example, best practice patterns) i have never actually seen people programming. So i absolutely miss the craftsmanship side of things. Anyway thank you for Pharocasts.

Making a .st file from the source of a method
by Sean P. DeNigris Jan. 29, 2011

Jan. 29, 2011

I have a class that I use to set up my images. A subclass has a method: setupScript (Smalltalk at: #UpdateStreamer) new updateFromServer. "Do other stuff..." I want to save the statements of the method above in a .st file to pass as an argument to the vm. That's all working, but in order to retrieve the two statements above, I do: setupScriptContents | scriptMethod sourceString sourceStringWithBracketsStripped | scriptMethod := PharoTrunkImage compiledMethodAt: #setupScript. sourceString := scriptMethod methodNode body asString. sourceStringWithBracketsStripped := sourceString copyFrom: 3 to: sourceString size - 2. ^ sourceStringWithBracketsStripped. That works, but I don't like it. What's the best way to do this (or is this it)? Thanks.

Serial Port
by Joan GÃ¼ell Jan. 27, 2011

Jan. 27, 2011

Hello We are developing software to interact with small robots for educational purposes. To do this we need to use the serial port. SerialPort class that includes Pharo does not work on mac or linux, because itÂ´s not able to open ports by name. It would be interesting that future versions include a SerialPort that would work in these circumstances. we are using since a time aÂ´go the plugin that comes with Scratch, with this we just copy the plugins in the folder of the VM, the Plugin that comes with the VM Scrath, and add to the image of the image classes of Scratch , ScratchPlugin and SerialPort2.Up to date this has worked on all VM including the latest Cog. It works on Linux, Mac or Windows.We wory that future versions will lose support. The source code for the plugins can be found on: http://info.scratch.mit.edu/Source_Code ScratchPluginSrc1.4.zip Joan GÃ¼ell jguell(a)e-citilab.eu Joan GÃ¼ell jguell(a)e-citilab.eu

Dear Smalltalkers, I am glad to make an updated version (v9) of the mocking framework TestMock available with added Pharo 1.1.1 support. Previously reported v8 issues arising from the deprecation of KeyedSet and some other changes with TestCase and Boolean classes in Pharo 1.1.1 have been fixed. This version continues to work with Pharo 1.0 and Seaside-2.8 dev images as before. Here is the link to the project: http://www.squeaksource.com/TestMock.html Happy smalltalking!

Hi all, I have now tried the minimal images indicated by Torsten and Stephane, on Windows it amounts to 9.1 Mega in memory ... Would it be smaller on Linux ? Yet, I still need a shoe horn, having only 8 M ram from which 1.5 is already taken by the kernel... Any idea to downsize even more ? Best regards Annick Fron

Pharo on Windows
by Andrew Black Jan. 22, 2011

Jan. 22, 2011

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

soft write barrier
by Norbert Hartl Jan. 20, 2011

Jan. 20, 2011

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

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 ...

squeak vm without MMU
by Annick Fron Jan. 13, 2011

Jan. 13, 2011

Hi, Is it possible to use pharo on a processor with MMU (Memory Unit Management ) ? Namely my target OS is a Linux with the following differences : ============ The kernel is a collection of patches to make the standard Linux kernel run on CPUs that do not have an MMU. As a consequence you will encounter some differences between the kernel and the standard Linux behavior: u no fork() â consider using vfork() instead but beware of the difference of their semantics u no daemon() â it is usually implemented on top of fork and cannot be easily replaced without changing the semantics. u fixed stack size -- the stack of an application is set at execution time and cannot grow during runtime. The default stack size is 4k! It can be increased with the "-s" option of m68k-uClinux-elf2flat. u limited libc compared to glibc -- either add more to libc, or remove some functionality. u no support for ELF binary file format u very limited support for shared libraries due to missing MMU -- all applications get linked statically u mmap() is very inefficient u no paging -- applications have to be loaded completely into RAM, the heap is very susceptible to fragmentation. ======== Annick Fron

Finding RB parse tree rule for replacements
by HernÃ¡n Morales Durand Jan. 13, 2011

Jan. 13, 2011

Recently I wanted to replace all method sends of oldMessage to newMessage in a specific method category in a class, then I wrote this little script I want to share with you: | className realClass replacer category | className := #MyClass. realClass := Smalltalk at: className. category := #accessing. replacer := RBParseTreeRewriter new replace: '`receiver oldMessage' with: '`receiver newMessage'; yourself. (realClass organization listAtCategoryNamed: category) collect: [:sel | | parseTree | parseTree := ( realClass >> sel) parseTree. (replacer executeTree: parseTree) ifTrue: [ realClass compile: replacer tree newSource " [1] " ] ] Now some questions: 1) In [1] "( RBClass existingNamed: className ) compileTree: replacer tree" would be more appropiate? I get a MNU when evaluated with latest AST/Refactoring. 2) The above script have some problems, if you want to get replaced 'this is a string' asString. to 'this is a string' asText it won't match. The same happens with: " self model asString " and other patterns. How to modify the rewriter to match oldMessage/newMessage at any point? i.e. [: tmp | anObject1 blabla1 blabla2 oldMessage blabla3 ] Thanks in advance, -- HernÃ¡n Morales Information Technology Manager, Institute of Veterinary Genetics.

GUI confused
by Jeff Gray Jan. 5, 2011

Jan. 5, 2011

I've been looking at the UITheme examples such as exampleBasicControls. I'm used to building windows (in e.g. C#) where I create a subclass of a window class and then extend it with controls and methods. Looking at the UITheme examples it is building up a window by creating an instance of PluggableDialogWindow and then calling methods to add controls. If I have a number of windows in my app would I have one class to build all the windows? How do I hook up methods? Would they be methods in this window building class? Am I missing the point? :-) -- View this message in context: http://forum.world.st/GUI-confused-tp3175361p3175361.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Telnet client
by Aidan Gauland Jan. 3, 2011

Jan. 3, 2011

Hi, I want to create a MUD <http://en.wikipedia.org/wiki/MUD> client (a client for games played over Telnet) with Pharo, but I'm stuck on how best to use Pharo as a Telnet client. I've heard of the cURL plugin, but I'm not sure if that can be (easily) used for anything other than file transfers. Even if I built and installed it, I'm not confident I'd be able to tell for certain whether I can use it in the way I want. I also found this <http://map.squeak.org/package/14bcecc6-dbb8-4866-bb0c-25278ca882ba>, but that's about eight years old and its homepage link is dead, so it doesn't look too promising. I found TelnetProtocolClient in the Pharo image, but that does not seem to be at all what I need. Can someone with experience with telnetting from within Pharo/Squeak point me in the right direction? Thanks, Aidan
