Re: [ENH] submorphsCleanup-efc

> I often use copy in default access methods. The motivation is increaed > robustness; it can be very risky to modify a collection. While a read-only accessor may have its place, in *this* case, robustness is decreased, not increased. If you don't want to allow direct access to a Collection, then what do you think about providing various enumerating / adding / removing / finding api from the containing class? I generally disagree with having code that "cross-checks" potentially incorrect code elsewhere. Besides the aforementioned performance degradation, it can inhibit learning because it allows misuse and then even increases confusion/uncertainty about the necessity of it when you try to remedy it (just like right now, we're all scratching our heads about this!). > submorphs do: [:m | ........ ifTue: [m delete]]) In this case, I think we should let anyone who tries misuse in this way learn. Let those who already know benefit from the increased performance of not copying submorphs every single time we ask for it. - Chris

First attempt at SVG for squeak
by Gary Chambers 30 Jul '05

30 Jul '05

Works with stock 3.7 and 3.8 image. I have tested this (worried because its my first upload!). As in the SqueakMap description, this is a first attempt, it works with simple svgs, and more complex ones (maybe with artifacts). It is far from complete (no text support for starters, and enders, probably!). Additonally, Arcs are approximated with Bezier curves and some of the other SVG privitives are not yet directly supported. If you wish to test then some of the samples provided with Inkscape (http://www.inkscape.org/) work ok (especially tux.svg!). Hope this helps.

Squeakmap servers down?
by Iede Snoek 29 Jul '05

29 Jul '05

Hi all, Could it be that that the squeakmap servers are down, or is my internet connection doing strange things? I have loaded the latest 3.8 image and I can't get updates, nor install anything from squeakmap. Thx in advance for your replies. Grtz, Iede Snoek

28 Jul '05

In Usage section , you read matcher := RxMatcher new initializeFromString: Should be changed to matcher := RxMatcher forString: as initializeFromString non exist in Squeak version of VBRegex. Apply to 3.7, 3.8, 3.9 as the package is the same, VB-Regex-avi.2.mcz I add the report to Mantis , but send to list as think Squeakers could wish know edgar ___________________________________________________________ 1GB gratis, Antivirus y Antispam Correo Yahoo!, el mejor correo web del mundo http://correo.yahoo.com.ar

Hi, can anyone make the image available? After several attempts to build an own SqueakSource server I gave up since it was not clear which packages in which version were required. Anything new from SqueakSource 2 development? Thx Torsten -- GMX DSL = Maximale Leistung zum minimalen Preis! 2000 MB nur 2,99, Flatrate ab 4,99 Euro/Monat: http://www.gmx.net/de/go/dsl

Creating a hotlink in Squeaklet
by Rudolf Coetsee 28 Jul '05

28 Jul '05

Hi I am trying to create a hotlink inside a squeaklet that will launch a new browser window which will navigate to the URL indicated by the link. The only way I can think of doing this is to activate a javascript function from within the squeaklet, which means I have to somehow register a callback to the function when the squeaklet is loaded into the browser window. Does anyone know how this may be accomplished? Thanks RUDOLF COETSEE
