How do we create a seamless loading experience for people that have not been keenly following the Metacello & Pharo lists for the last year? If I downloaded Pharo today, where's the central access point I would go to load something? Things seem scattered - Metacello configurations can all be found in MetacelloRepository... unless they are with their projects... or both, with one or the other out of date. Loading scripts are often posted to the list, but do they ever get captured into a configuration? It's embarrassing, but I didn't even know about Metacello's Toolboox API unless I read the beta chapter from PBE2 yesterday - I thought configs all had to be coded by hand! - so I never quite "had the time". What can we create to tighten up this process and empower (especially new) users?

[Pharo-project] Task List
by Sean P. DeNigris Nov. 8, 2011

Nov. 8, 2011

I think the task list would be much more useful and easy to use if we follow Mac OS X's interaction semantics. Currently, in Pharo's non-keepOpen mode, the morph disappears every time you unpress the arrow key, so you're limited to a brief tease as the morph flashes for an instant, or trying to play roulette and unpress the arrow at just the right time as the tasks scroll by at lightning speed. In the keepOpen mode, the morph stays in place until you make your choice, which is nice, but making the choice requires an extra key press (enter). On the Mac, the shortcut opens the UI, which stays open as you hold the modifier key and repeatedly press the shortcut character key. When the modifier key is unpressed, the choice is accepted.

The documentation and PBE are really good, but the authors have limited time to manage them, and only focus on the things that they deem important. Which is entirely fair. But there are is tons of tacit knowledge in the Pharo community that should be organized and made explicit. Wikis are great for that, enabling anyone to add content and to organize it over time.

[Pharo-project] bootable Pharo image
by Pavel Krivanek Nov. 8, 2011

Nov. 8, 2011

Hi, I tried to prepare a bootable Pharo ISO image based on Tiny Core Linux. Namely on MicroCore (kernel 3.0.3) that was extended with WiFi support. There is standard Pharo 1.3 image with OSProcess and CommandShell installed on the Smalltalk side. The resultant image has about 37 MB. Download: http://www.windmap.cz/playground/pharo/pharo.iso If you want to add it directly to your Grub menu, you may do it without need of extra partition. To the grub.conf add something like: title Pharo root (hd0,1) kernel /boot/pharo/vmlinuz vga=791 quiet initrd /boot/pharo/tinycore.gz where vmlinuz and tinycore.gz are the only files needed from the ISO image. Remastering: unpack: zcat tinycore.gz | sudo cpio -i -H newc -d pack: find | cpio -o -H newc | gzip -2 > ../tinycore.gz better compression: advdef -z4 tinycore.gz create ISO (you need unpacked original ISO image): /bin/cp -pfr tinycore.gz boot mkdir -p newiso /bin/cp -pfr boot newiso mkisofs -l -J -R -V TC-custom -no-emul-boot -boot-load-size 4 \ -boot-info-table -b boot/isolinux/isolinux.bin \ -c boot/isolinux/boot.cat -o pharo.iso newiso Cheers, -- Pavel

[Pharo-project] Best practices for overrides/extension methods with Monticello and correct packaging?
by Stefan Marr Nov. 8, 2011

Nov. 8, 2011

Hi: I was wondering what the standard approach is to package rather invasive changes to core classes. Currently, I have everything in extension methods that override the existing methods in my own package. However, the monticello package is not actually loadable. So, I cannot just load my stuff into a new image via monticello. For instance, I modify #basicNew/#basicNew:, the Parser, the Encoder classes, etc. With my changes, these things depend on my own classes being properly initialized in the image. What is the best way to get that into a loadable/bootstrapable state? Do I need to split up all the stuff into different packages according to dependencies and then make sure that I can load those different packages in a well defined order? Or is there anything to tell Monticello to be smarter about loading the stuff?
