Package Universes and Squeakmap
by Keith Hodges 23 Sep '07

23 Sep '07

I have been using package universes for a few days, and have discovered some of its limitations. I have also been wondering how best to integrate its use with SqueakMap. We already have SqueakMap as the master repository and Lex, the creator of package universes does not seem to think that simply tagging items in SqueakMap according to what works with what and what doesnt would work very well, all things considered. To a certain extent I now agree with him. I initially thought that having Universes separate from SqueakMap was a bad idea. However, after using universes I have now changed my mind and think that is a good idea. I imagine SqueakMap to be the Model, and Universes to be the View, with the community acting as the controller so to speak. One of the limitations of Universes is that it does not have much in the way of integration with Squeakmap or Monticello, and so it looks to be attempting to make SqueakMap obsolete, but it is somewhat of a poor replacement. At present it is totally agnostic to the package provider, it simply loads a package from a url based upon the file's extension. One of the positive things about SqueakMap is that it caches the packages, it also has more information on it than the universe. I think that it too would benefit from some feedback features, and more openness, and some indication of dependencies, but perhaps it makes sense not to have these as hard and fast rules. For example, Seaside specifies Kom, but some users may prefer Swazoo. This flexibility seems difficult to support prescriptively on the macro level, but could be supported in local mini/sub-universes, such as a "Swazoo users seaside universe". Perhaps SqueakMap could allow anyone to upload a new version, but reserve "blessing" of releases to the owner/maintainers, since this is how a public squeaksource repository works by "social" default. One Universe limitation is that when using a Universe package, unlike an installer script which integrates with the native monticello tools, the package is loaded, but the Monticello browser is not informed of the repository details. This means that you have to manually inform the Monticello Browser of the required repository before a monticello package with dependencies referred to in a package universe will work. For example when Chris posted 'Magma Server' he would have had the Monticello Browser properly configured on posting the package to the Universe and it will work for him but it will not work for users out of the box who do not have the Monticello repositories configured. So thinking about it this it would not be a problem at all if Package Universes replaced: http://www.squeaksource.com/Magma/MagmaServerLoader-cmm.25.mcz with: Installer squeaksource project: 'MagmaTester'; install: 'MagmaServerLoader-cmm.25'. So why not have Package Universes call installer for SqueakMap items too. Installer squeakmap install: 'MyPackage(1.0)'. (I will fix installer to fall back onto using the http interface #websqueakmap if SMSPackageLoader is not present) By doing this we can uphold the use of SqueakMap as the place to publish released packages, with Universes being the place to define dependencies within a locally defined context/scope/use scenarios. If the "publish to squeakmap" button could be fixed on squeaksource the picture would be complete. This approach also allows mantis fixes and change sets to be included in the Universes without any extra work. thoughts feedback? best regards Keith I think that having universes, together with sub-universes and personal-local universes

If the user is likely to lose data, then yes. I usually use Squeak full-screen, and IceWM asks me for confirmation anyway. == Really? Wow, I don't remember KDE nor Gnome asking. Xfce4 certainly doesn't

People: At ftp://elpelotero:elpelotero@200.3.221.230/Public/ NASASqueakLight.389.image you have several NASA last mission photos to puzzle with. The original 12 jpg photos was 4.9 mb. The image is 5.2 mb Use the same SqueakV3.sources , so put in same folder of regular Squeak. Some people complain, some people work. Enjoy first Spring Sunday with your kids ! Edgar PS: Today only, maybe some have better cable modem , mine is slow for upload

creating instance variable accessors
by Jimmie Houchin 22 Sep '07

22 Sep '07

Hello, Do any of the browser have the capability of creating accessors for all instance variables at the same time? Or also, the ability to create accessors for variables which do not have accessors? I thought I had seen the ability to create accessors in a browser a few years ago. But I am missing it or overlooking it in the browsers I've seen in the squeak-dev images. While working today, I was using the RB browser and it offered the ability to create accessors, but for only one variable at a time. While easier than manually doing it one variable at a time it would be nice to have the option to do them all at once. If not I might have to look at the OB browser code and figure it out. :) Thanks for any pointers. Jimmie

Squeak Roadmap ...
by GeertC 22 Sep '07

22 Sep '07

What does the roadmap look like for the Squeak core image (the one downloaded from www.squeak.org)? I reckon the recent Squeak (Squeak by Example) and Seaside (the paper) documentation efforts are great! As are Garry's UI Enhancements (maybe a tutorial on how to make such UI Enhancement will encourage others to improve the Squeak look and feel?) What I would like to see in Squeak's roadmap is an effort to clean-up the core image (remove eToys ect ... maybe even leverage on what Pavel has been doing?) and improve the default Squeak look and feel. The "Squeak by Example" book depicts Squeak as "a modern implementation of the Smalltalk programming language and environment" and it would be great if it looked like one too :) -- View this message in context: http://www.nabble.com/Squeak-Roadmap-...-tf4484094.html#a12787133 Sent from the Squeak - Dev mailing list archive at Nabble.com.

Extended 'senders of' , 'implementors of' filtering
by Igor Stasenko 21 Sep '07

21 Sep '07

Hi all, Is there have some support in browser tools for filtering senders/implementors of given receiver? Sometimes i really need to filter senders/implementors which found only in single package or in all subclasses of some class. For example, try senders of 'value:' - in my image it shows list with 1119 entries. Its impossible to find only those which interesting to me. The only way around is to use not so common selectors for own methods. But even this can't help, if you want, for instance, to find all senders of 'value:' in your classes, because it get flooded with image-wide search results. -- Best regards, Igor Stasenko AKA sig.

Hi all, I have updated SuperSwiki2. http://swikis.ddo.jp/SuperSwiki2/3 This is a little improved version from the demonstrated one in SqueakFest 2007. But I recommend to update it. New features: - Auto select default language by seeing "accept-language" of Web Browser - "Search the SuperSwiki" support from legacy (normal) SqueakPlugin - Spanish-Mexico translation support (Thanks Octavio for sending me a new trans file) - All-in-one pack now runs on Intel Mac! (it was shame) (etc...) You can see a sample site here: (in Japanese) http://squeakland.jp/super2 Platform Independent Downloads: http://swikis.ddo.jp/SuperSwiki2/19 Windows installer: http://swikis.ddo.jp/SuperSwiki2/18 CD (Memory stick) bootable ISO image: http://swikis.ddo.jp/SuperSwiki2/24 Enjoy! -- [:masashi | ^umezawa]
