String quirks
by Alexander Lazarević 27 Feb '11

27 Feb '11

Some methods like subStrings start with a line like #Collectn. What is this good for? And what is the IntegerPokerPlugin found in getInteger32:? And do we need String arithmetic that mimics Number arithmetic like '1two' + '2' -> '3' Alex

Re: [squeak-dev] SqueakMap for documentation?
by Chris Muller 26 Feb '11

26 Feb '11

As a demonstration, I threw together some (very) brief slides about Maui and slapped them up on SqueakMap. Refresh your Catalog, then install the 'slides' release of the 'Maui' package in the Catalog. My slide-presentation will pop-up on the desktop. To answer your question at a higher level, there are two parts to SqueakMap: 1) an elegant object model which is the catalog of Squeak packages. Each package has an OrderedCollection of Releases. Each Release knows what version of Squeak it works in and other things too. It also knows its #downloadUrl. 2) The #downloadUrl can refer to a file that is a file on an external web-site or a file on the SqueakMap web-site itself. The important point is that it refers to a _file_ that SqueakMap gives to its own "SMInstaller" to install. SMInstaller is not redundant with Installer. SMInstaller installs several types of external files, such has human language files, for example. But the most generally powerful one it can install is ".sar", which means Smalltalk Archive. A Smalltalk Archive is not only a way to publish MC-packages and st-scripts, but to also include any necessary resource files as well. My slide-presentation is just a .morph file, which I made by filing out the root Morph of the slide-presentation. The resource files could just as easily be documents in any other format, graphics, movies, sound samples, entire databases, or even other Squeak images.. I should mention, Squeak and Pharo include SARInstaller, out-of-the-box. This rawness is the beauty of SqueakMap: it assures maximum compatibility and maximum flexibility without needing to reinvent anything. It's a tool that allows us all to be publishers on a rich medium. It's full access to the consumer's image (assuming security permissions are enabled in the VM, of course) where we can really showcase our ideas and projects using this great medium for doing just that; Squeak itself. We should do it! I know SqueakMap has lost popularity because it has struggled with usability, but this has mostly been addressed: I've recently added the Release editor for publishing load-scripts straight-away from the image, and for demos and documentation we have MaSarPackage which provides a nice GUI to generate the SAR's that install automatically.. - Chris On Thu, Feb 24, 2011 at 3:32 PM, Ken G.

Re: Adding a Quora bot on the #squeak IRC channel
by Simon Michael 26 Feb '11

26 Feb '11

Hi Alexandre.. I think it's a good idea. I've added squeakquorabot, which polls hourly and will announce new questions (and hopefully not updated ones, we'll see.) (Also I've made squeaksobot poll stack overflow hourly instead of every six hours. This one does announce old updated questions as well as new ones, but I think this is a small enough problem to ignore.) Don't let this stop you writing a smarter squeak-based bot, or reviving an existing one; it's a nice real-world project.
