But I prefer InstallShield (after switching from Wise) these days which is nice to work with... But to have a reproducable and completely free build for a community project) NSIS is a viable alternative. Not as comfortable but free as Squeak itself. And there are many add on packages and tools out there. >I haven't looked at your install but one thing that I never quite got is >how the whole Smalltalk image model plays into this. As you know like most Smalltalks it does not integrate very well with the underlying platform - and so not very well with the startup menu. But you can associate the *.image file with the VM, the downside is that you have to navigate the image folder first. The setup was intended as a simple "starter" to wet the appetite if someone just want to plays with the system first. >From time to time newbees have problems with this whole "you need this VM, unzip this source and changes and this image". People first want to easily try and later learn and read if they get interested. The setup was also intended as a "howto" create and deploy custom end-user applications (where you typically dont save images). It included a description how to build a custom VM and distribution. Thats often a question on the squeak and pharo lists as you may know... >Considering that the installation location for an application is >generally read-only I guess you mean on Vista the program folder is (depending on rights) not writeable by the application after installation. Thats why the application folder in the users directory is the predefined (but changable) install folder. Thats easy in NSIS: !define TARGET_DIR "$LOCALAPPDATA\${PRODUCT}" >Or do Pharo users not save their images? No - Pharo users use Squeak images and always do a fresh bootstrap ;) Just kidding, I think most Pharo users are Squeak users and vice versa. At least I'am. So I will save images in both :) We should make Squeak and Pharo easily accessible even when it is different than what others expects. We just have to make it more familar. Typically have only one chance to get people into something... Bye T. -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT! Jetzt freischalten unter http://portal.gmx.net/de/go/maxdome01

Re: need help building one-click squeak app for Windows

For Win32 it would be better to create a typical windows installer (setup.exe or setup.msi) which is what most people expect (yes there are windows user who dont know about zip ;) It's easy to create, I've done one using the NSIS (Nullsoft scriptable install system) to build a setup for the latest pharo. See my short HOWTO on the pharo list, which is also accessible from my blog posting [1]. The latest pharo can be tested on Windows by using such a setup (see [2]). Use at your own risk ;) Would be easy to provide the same for Squeak - currently it is done manually. Would be easier if one could provide a windows build machine with net access to automate it. On the other hand a "one-click" leaves no traces on the system when you delete the directory ;) Bye Torsten [1] http://astares.blogspot.com/2009/05/pharo-preview-setup-for-windows.html [2] https://gforge.inria.fr/frs/download.php/22428/setup_pharo_0.0.0.4.exe -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT!

need help building one-click squeak app for Windows
by John M McIntosh 15 Jun '09

15 Jun '09

Well it appears I need some help building a one-click app for Wikiserver for Windows. I can cheerfully build the mac version, and the LInux version. But the Window's version has proven to be a bit more of a hassle. So I'm looking for someone who can help me complete that chore, please email me privately. No-doubt you get a promo code for the iPhone Wikiserver in return. -- = = = ======================================================================== John M.

Install error with latest LPF
by K. K. Subramaniam 15 Jun '09

Hi, I got a DNU for ChangeSet>>removeChangeSet with etoys 4.0 image+LPF while attempting to install OSProcess: SARInstaller installSAR: 'OSProcessV4-3-6.sar' removeChangeSet is defined for ChangeSorter but not for ChangeSet. LPF.st changed the class name in SARInstaller triggering this error. Am I using the wrong LPF (ftp.squeak.org/3.11/bob/LPF.st)? Thanks in advance .. Subbu

SmaCC uses Refactrory Browser!?
by Ralph Boland 15 Jun '09

15 Jun '09

I downloaded Squeak 3.10.2 a couple of months ago and just now attempted to use SmaCC but discovered that it references a class RBNamespace (SmaCCGrammarCompiler>> initialize) which is not in my image and which I believe is a subclass of the Refractory Browser. Is there a version of SmaCC that runs in 3.10.2 and does not use the Refactory Browser or must I load the Refactory Browser into my 3.10.2 image? Ralph Boland

>> >I doing some .mov recording beginners tutorials and wish put in some place. >> >Any favorites for this ? My modest LAN and lousy ISP cable modem is not so >> good .... I almost forget Morphle.com could host this. So , in http://www.morphle.com/~edgar/UsingSqueakSource.mov you have the first showing how use SqueakLightIi, SqueakSource and have a working code + music + morph + etc thing. Same could be done with MinimalMorphic, with a few easy to fix glitches. Enjoy and wait for more Edgar

Serial Port(s) from multiple processes
by Jon Hylands 12 Jun '09

12 Jun '09

Hi everyone, I've got a couple USB-based serial ports on my robot BrainBot, and I've got four different processes - two for each port. One process reads from the serial port, and one writes to it. For each serial port, I have a mutex semaphore to protect access to the port, like this: readData ^portAccess critical: [serialPort readByteArray] writeData: aByteArray portAccess critical: [serialPort nextPutAll: aByteArray] Those two methods are implemented in the same class, and thus the 'portAccess' instance variable (which is a Semaphore) is shared between read and write, but not between different serial ports.. I have two instances of this class, one for each USB device plugged in (the USB devices are both FT232-based interfaces, one at port 4, the other at port 5). The question is, do I need to protect the two instances of SerialPort with a single Semaphore? Looking at the serial port code for read/writing, it looks like the code just jumps directly into the primitives. I was under the assumption that primitive execution can't be pre-empted, and therefore the code shouldn't need mutex protection. Am I missing something?

[ANN] New 3.10 compatible reduced .image

Folks: I retake MinimalMorphic as Pavel Krivanek do some years ago (before 3.10 start) and me help to build and now put all I learn doing SqueakLightII into So this could do almost a regular 3.10 do plus some 3.10 never dream of do. As if you open MonticelloBrowser and add http://www.squeaksource.com/TaiPei http://www.squeaksource.com/Rompecabezas And you see how you could put some more as only code in SqueakSource. TaiPei is still in buiding phase and Rompecabezas have some time living in different images. ProcustesEnd stiil could be polished, but all have now some to play and improve. As final data MinimalMorphic.7229.image have only 7.3 MB and equivalent SqueakLightII.7229.image 11.2 Also , as many like Traits, this image have they, but could easily removed with Matthew procedure. I doing some .mov recording beginners tutorials and wish put in some place. Any favorites for this ? My modest LAN and lousy ISP cable modem is not so good .... Enjoy http://ftp.squeak.org/various_images/SqueakLight/MinimalMorphic.7229.zip Edgar

What does the underscore do?
by Gary Dunn 12 Jun '09

12 Jun '09

As I was poking around in the system browser I came across code that used an underscore as if it were an assignment statement. By that I mean a _ where I would expect to see a :=. What does it do? Several examples in the directory: method in FileList2. directory: dir "Set the path of the volume to be displayed." self okToChange ifFalse: [^ self]. self modelSleep. directory _ dir. self modelWakeUp. sortMode == nil ifTrue: [sortMode _ #date]. volList _ Array with: '[]'. directory ifNotNil: [ volList _ volList, directory pathParts. "Nesting suggestion from RvL" ]. volList _ volList withIndexCollect: [:each :i | ( String new: i-1 withAll: $ ), each]. self changed: #relabel. self changed: #volumeList. self pattern: pattern. directoryChangeBlock ifNotNil: [directoryChangeBlock value: directory]. -- Gary Dunn, Honolulu osp(a)aloha.com http://openslate.net/ http://e9erust.blogspot.com/ Sent from Slate001
