How to add a TraitExclusion to used Trait
by Juraj Kubelka 26 Aug '07

26 Aug '07

Hi everybody! Let's say there is: Trait named: #T1 uses: {} category: 'Example' Trait named: #T2 uses: T1 category: 'Example' T1>>method1. T1>>method2. And I would like to recompile T2: Trait named: #T2 uses: T1 - {#method1} category: 'Example' Do you have an idea how to exclude #method1? Something like: T2 excludeSelector: #method1. I would like to use it in such situation: If user has selected T2>>method1 in a System Browser and wants to remove the method, system will ask: '#method1 comes from used trait T1. Would you like to:' - Remove method from trait T1. - Exclude method from T2' - Cancel Thank in advance. Juraj

It's new syntax, and messages and syntax should be distinct. Your suggestion qualifies in that respect. But would it be too similar to the single ";" character? --Alan

The backtick ( ` ) might look nicely and is unused yet :) 2007/8/26, Alan Lovejoy <squeak-dev.sourcery(a)forum-mail.net>: > Since the selector #'|' is already taken for other purposes, why not use > #'!' instead (exclamation point instead of the bar)? > > >

Of the various Squeak parsers that will parse HTML, does anyone have any recommendations as to what is the best at this point?

[ANN] AIDA/Web app server 5.4 released
by Janko Mivšek 25 Aug '07

25 Aug '07

Dear Smalltalkers, AIDA/Web 5.4 is here, on Squeak and VisualWorks simultaneously while Dolphin and Smalltalk/X ports are coming soon. What is new in 5.4? - more robust and seamless Ajax support, you won't even notice that you are doing Ajax! - input streaming (for large file uploads) and output streaming/chunking (for large file downloads and HTTP streaming/Comet) - WebGrid ajaxified filters - better real-time statistics including referrers - better integration of the TinyMCE Rich Text Editor - tabulation with ENTER key besides TAB one - reorganization of packages You are invited to try Aida, just follow download and installation instructions at http://www.aidaweb.si/download.html. For additional questions and suggestions please join a mailing list at: http://lists.aidaweb.si/mailman/listinfo/aida . To introduce it a bit: AIDA/Web is a web application server and framework for building complex web applications with seamlessly integrated Ajax support, rich collection of web components to build web pages programatically, MVC-like separation of presentation from domain, nice looking and bookmarkable RESTfull url links, with integrated security, user and group management, static file serving and many more. AIDA/Web is known by its simplicity but power to build most demanding web applications of many sorts. It has everything you need for a real web app, together with Ajax. It is also a mature one, running web apps in production since 1996. It is used in many intranet business apps from Gas billing system for all gas in Slovenia to logistics management system called e-logis and recently a CMS like system for Quality and Business process management. I hope that Smalltalkers will find Aida useful and a good choice for building your most demanding web applications! Best regards Janko -- Janko Mivšek AIDA/Web Smalltalk Web Application Server http://www.aidaweb.si

Squeak on Debian
by Matej Kosik 24 Aug '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear Squeakers, Would you mind creating link to http://wiki.squeak.org/squeak/3616 from the official Squeak download page http://www.squeak.org/Download/ I mean, not among "Other" but as "Debian GNU/Linux" on par with Mac and Windows. The "Other" category seems to be just a lump of files with a "good luck with installation" whereas the Debian repository is a decent way of installing software on Debian (you know, metainformation attached to the distributed files such as depends (with version constraints), build depends, provides, conflicts with, sharing common components, pre/post installation/removal actions and such). Objections against this might be rational if the packages were in a bad state (I think they are not) but if noone finds them, I will hardly see any complaints or feedback. There are people who have reasons to prefer Debian GNU/Linux over Mac or Windows and these packages are for them. Let me know what you think.

Am Freitag, 24. August 2007 00:09 schrieb Lex Spoon > I believe there is room for a community-maintained version of Squeak > on Unix. Hi Lex, I agree with you. But is it necessary to *install* Squeak even for a single user? It seemed to me also before you wrote it in the mail that some of you guys work very hard to Squeak run under Unix / Linux. As far as the installation process is concerned: would it be a good idea to drop some lines on the category installation on the website? Then it need not to be necessary that specific differences for the package on different distributions have to be described in the package itself. Since it is deeply recommended to use inisqueak, and since you get this information even on the net (not from the Squeak-site), it will be a great help for newbies to have a place at the site where to look up the correct hints. Yes, I know that *squeak* succeeds if you do not have *inisqueak* under SuSE-Linux. Thanks anyway. But hopefully the work for the Unix versions is not that hard, that one day the community will only emphasize on Mac or the OS lookalike Windows ;-).

DeltaStreams small update
by goran＠krampe.se 24 Aug '07

24 Aug '07

Hi all! Ok, managed to get some more code written tonight - but I am still on a low level here - matching up with ChangeSet etc. But if anyone wants to join in: See details here: http://wiki.squeak.org/squeak/6001 The first goal is to make DSDelta work as a "true log" capturing all changes in full detail. One question for you gurus out there - do we care about changing the ORDER of say instvars? regards, Göran
