veryDeepCopy, ImageSegments, and actionMaps
by Ned Konz 17 Aug '23

17 Aug '23

Any Object can have dependents whether or not it has an instance variable to keep track of them (these are kept in the DependentsFields class variable of Object). The only class that keeps its own dependents is Model. Any Object can have an actionMap. These are supplied by EventManager class by default, and are stored in the ActionMaps class variable of EventManager. The only class that keeps its own action maps is Morph. When we veryDeepCopy an object we also copy the global dependents (see DeepCopier>>fixDependents). However, we don't copy the actionMap in those cases where it's held by the EventManager class. When we file out an object that uses DependentsFields out into an ImageSegment, we also file out the dependents (see ImageSegment>>dependentsSave:) if it's in a project. We do this by adding a project parameter called #GlobalDependentsInProject. However, we don't file out the actionMap in those cases where it's held by the EventManager class. My question is this: should we fix these behaviors (copying and serialization) to include these "global action maps" just like we already include the "global dependents"? Or should we discourage the use of the "global action maps"? -- Ned Konz http://bike-nomad.com GPG key ID: BEEA7EFE

Trying to build SerialPlugin for IrDA under MPW (MacOS 8.6)
by Hans-Martin Mosner 24 May '12

24 May '12

Hi, I recently got a serial IrDA adapter and wanted to play around with it under Squeak. This adapter has a baudrate switching mechanism which depends on toggling the DTR and RTS lines in the correct sequence. To support this, I wanted to build a new SerialPlugin with an additional primitive. However, the plugin as built with MPW does not seem to be accepted by the VM, which still uses the internal plugin in all cases. I've tried placing the plugin in a 'Plugins' subfolder of the VM's folder, and then directly into the VM folder, without any success. I have considered placing debug outputs in appropriate places in the VM, but building a complete VM with MPW is not easy - I would have to create an MPW makefile for the whole shebang, which is more work than I can invest at the moment. Does any of you Mac aficionados have an idea where the problem could be? I have appended the plugin and corresponding source files in a ZIP file (it's not big) so if you want to try it out you could do it right now :-) BTW, would it make sense to incorporate support for switching serial port parameters of an open port into the standard plugin? Closing and opening a port just to change the baud rate seems a little overkill... Cheers, Hans-Martin

Squeak download stats?
by Thomas A Petersen 27 Feb '11

27 Feb '11

Greetings, FWIW, I download beta/gamma versions about once a month to test. Those that prove stable get my influx of current work for day to day use. I download the official version and move to it if it proves stable for my uses until about the middle of the next beta cycle. I also have a couple of friends that I pass the stable specialized images on to about once a year. A couple of other people I know pull the distribution for Windows and/or Linux when I let them know there is an official upgrade. Thanks again for a great place to think and learn, tap

TextMorph behavior
by Marcus Pedersén 18 Jan '11

18 Jan '11

Hi! I have been trying class TextMorph out for making an editable textfield for my GUI. One thing I can't figure out is how to make the text "grow" horisontaly when you write instead of verticaly. I am after the behavior similar to the spotlight search text field in mac. If you write loads of text the oldest text "dissapear" (visualy) on the left hand. I have tried autoFit: false and wrapFlag: false without any desired results. Doesn't TextMorph contain this functionality from start? Do I need to subclass and write the function from scratch? Many thanks in advance! Marcus

Loading the OpenGL package (was: Games with Squeak)

I missed the package too, because in www.squeaksource.com usually there is one MC package per "Project". Anyway, I'm trying to load OpenGL-ar.36.mcz in Squeak 3.9 but I get: Syntax Error: glBindBufferARB(target, buffer) "This method was generated by OGLExtManager" <Argument expected ->apicall: void 'glBindBufferARB' (long ulong)> Any clue on how to solve this error? (It looks that it's created with a "special" compiler) And another question... As I wrote in the previous mail I've started to do some SDL bindings. But I think that maybe it's a waste of time, since today nearly all machines have OpenGL, and Squeak already has objects to deal with sound and joysticks.... so instead of using SDL for 2D graphics is better to use OpenGL for the same thing, what do yo thing about that? Cheers, Diego

I have installed RB and AST from SqueakMap for 3.9, but I have many random problem swith features not working as hierarchy browsing, simple editing in the browser, refactoring tools as renaming methods. These problems happen more or less randomly. Hilaire

SqF feedback
by stéphane ducasse 21 Jul '07

21 Jul '07

Hi I'm reposting this email since I have the impression that the point was lost in its original thread. ... - Normally after election, politicians do not really listen anymore and I would like to do the inverse. I would really like to know what you expect or would like to see put in place. We have some ideas (bounty system, better process) and I will really listen what the new boarders want to do (I'm even eager to see that :)). We do not have the monopole of good ideas, so if you have some points that you would like to see happening please mention it. Stef

Monticello Versions and Bold Text
by Ramon Leon 07 Jun '07

07 Jun '07

Recently, I've been having problem in some images where Monticello no long correctly bolds newer versions of code. After opening a repository, the left column now shows all loaded packages as bold rather than just loaded packages with newer versions available. The right column now bolds and underlines the loaded package, rather than just bolding newer packages as it did before. I have no idea why the sudden change, has anyone seen this before?

ANN: separate Squeak packages created for different Debian vesions
by Matej Kosik 22 Apr '07

22 Apr '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Friends, To make sure that Squeak can be installed on every relevant Debian (GNU/Linux) version, I decided to create builds for all the three Debian versions: - - Sarge (known as "stable") - - Etch (known as "testing") - - Sid (known as "sid") It was not necessary because the same squeak binaries worked quite well on all of these Debian versions but it might have been confusing to add deb http://ftp.squeak.org/debian/ sid main deb-src http://ftp.squeak.org/debian/ sid main to `sarge' or `etch'. Additionally, the fact that the same set of prebuilt binaries worked well on all the three Debian versions is more coincidence than a rule. It is safer to distribute separate binaries because of the possible (non-)availability dynamic libraries against which our (Squeak virtual machine) binary is linked. This set of dynamic libraries in general differs from Debian version to Debian version. Details (what to write to your /etc/apt/sources.list file) are explained in http://wiki.squeak.org/squeak/3616 I have tried to install and use the following three packages: - - squeak - - squeak-plugin - - seaside on all the three Debian versions: - - stable - - testing - - unstable I have noticed no problems. If anyone does, let me know. When new Debian version rotation occurs (testing becomes stable, unstable becomes testing and new unstable will be forked), those repositories will be properly rotated to reflect that too. New packages (if some will have to be created) and enhancements of the existing ones will be put to the `unstable' subdirectory. If Squeak relicensing to Apache License 2.0 succeeds, that will also open new possibilities.

RFV: pinhead team needed
by tim Rowledge 15 Mar '07

15 Mar '07

We (as in the All Powerful and MightyBoard) are intending to produce some more nice enamel Squeak badges as fund raising items. The previous batch I did a few years ago proved very popular and we hope that offering them again will help fill the Foundation Coffers. I'm going to actually fund the initial purchase and hope that enough sell to at least cover most of those costs. This Request For Volunteers is seeking a few people that can help with fulfilling orders. I propose mailing a batch to each pinhead team member in, hopefully, several different parts of the world so that local postage will suffice for most orders. Volunteers will need to be able and willing to store some badges, obtain small padded envelopes or small boxes, mail them to supporters, submit their expenses and receive reimbursement by paypal. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Rules for Optimization: 1.
