I'm not sure this is accurate if I do open Squeak.app Squeakx.image Then with the carbon VM I get the VM launched which then asks me for an image via the file selection navigation services, AND I get a copy of the VM launched which opens the Squeakx.image. This is because the Squeak.app runs, then the Squeakx.image sends an open document request to the VM which then looks at the *.image and invokes some applescript to launch a copy of the VM with the *.image. This logic was developed a few years back to solve the problem of double-clicking on the a image file and it would open file browser in the running squeak.image which wasn't exactly what a person wanted. I note that saying open -a Squeak.app Squeakx.image does the right thing since it asks to open Squeakx.image with the application Squeak.app Now if I do open -a Squeak\ VM\ Opt.app Squeakx.image test.st then that starts the application, opens the image, and then opens the test.st in a file edit browser, well not what we want either. In looking at the issue for historical reasons I've done a cwd to the VM path when the app starts. If I remove that ./Development/Squeak.app/Contents/MacOS/Squeak\ VM\ Opt ./Development/ Squeakx.image test.st Well that works as desired, now I wonder about side-effects... Ok well it won't open the Squeak.image that is found in the same directory as the Squeak.app if you launch from the Dock because the cwd isn't done and I'd guess cwd points to '/' So let me add a change to check for no '.' or '/' on the image name means look in VM directory, so the default Squeak.image turns into a search for /Application/ Squeak.image if Squeak.app is in /Application/ Yes that works.

[Pharo-project] ScriptLoader>>installingInstaller
by Alexandre Bergel Oct. 28, 2008

Oct. 28, 2008

Dear List, I was wondering why this method contains: fileToLoad := files detect: [ :aFile | aFile beginsWith:'InstallerAll- md.1' ] ifNone: [ nil ]. It always load InstallerAll-md.1 Why not to load the last version of Installer-Core? Will it be okay to put "fileToLoad := files first" instead? (files is a sorted collection in a decreasing order of version numbers).

[Pharo-project] Arrggh - Squeak FFI in 3.10 again?!
by Torsten Bergmann Oct. 28, 2008

Oct. 28, 2008

Hi Kjell, I came across your postings on problems on installing Exupery [1] in Squeak. I'm sure your problem is the Installation of FFI in the 3.10 image again. Arrrgghh!!! See the bug + fix [2] - just file in the changeset from above location [2] before loading FFI and tell me if it works. Unfortunately I tried to convince the community several times (see [3] for an example) to update the default 3.10 download images: - since people typically start by downloading an image from the website - since FFI is a very often used package for some of us and some packages depend on it - since not every new user knows about bug 6980 But unfortunately still nobody really cares. Yes there are nice Installer scripts and friends - but they dont automatically fix this problem for a fresh 3.10 Squeak download. However I als filed a bug report + fix [4] for Pharo in the hope that this Squeak distribution will be more user friendly than the standard Squeak in the future...

First, you have to comment on the pharo-dev images to make them fit your needs. Then, you can embed the latest one into a One-Click that you generate (it seems I can't generate them myself because I don't use MacOS, but I'm not sure).

Hi! I've been told that Keith and maybe few others are working on a test server. In a 10 minutes seaside coding session I did a small application that displays a result of a SUnit test.

[Pharo-project] iPhone 1.07
by John M McIntosh Oct. 28, 2008

Oct. 28, 2008

I've push out an iPhone 1.07 VM. http://www.smalltalkconsulting.com/squeak.html This VM uses the latest core Pharo image. The VM has a number of changes to enable C data structure support and code examples for putting up a UITextEdit and UITextView for single and multiple line textual input, along with the ability to execute objective-c methods on the main thread versus the squeak thread. There is of course a new ObjectiveCPlugin for os-x users. For developers the key to getting a UITextEdit field to work is that you *must* create the UITextEdit thread on the main thread, otherwise if you create the object on the squeak thread, then attempt to use it for textual input on the main thread as per recommendations it deadlocks on a semaphore when it decides that the two process threads are different. Still to do is finishing the Keyboard entry logic, (oh I'm sure just a few minutes should do it...). Then I'll see if I can get a Menu control example working I've not included the VNC logic since I don't know if anyone uses it, or if it can be integrated into the Pharo image at this time, however I suspect someone will let me know. -- = = = ======================================================================== John M.
