MacOS Context application created

Posted in Context, Spoon with tags on 28 January 2011 by Craig Latta

I’ve created the first of the platform-specific launching mechanisms for the Context 3 release on 20 March, a MacOS application. On each platform, launching an application starts the minimal subject and history memories, and opens a website served by the subject memory using your default web browser. You can then control the subject memory from that website (load modules, quit, etc.).

For MacOS, I wrote an Automator workflow which opens the memories with Finder commands from an AppleScript, and opens the website after that. I saved the workflow as an application, and put the processor (AKA “virtual machine”) and memories in its Resources. This was my first serious application of Automator or AppleScript; I’m impressed!

I’m also writing applications for Ubuntu Linux and Microsoft Windows. I’d appreciate any suggestions about mechanisms to use on those platforms. I’d also love contributions of prettier iconography. :)

new Naiad memory visualization data

Posted in Naiad on 27 January 2011 by Craig Latta

minimal Naiad memory visualization, 2011-01-27

I’ve finished another manual pass through the minimal Naiad subject memory, and have generated another set of graph data for the Walrus 3D visualizer. There are 8,628 objects and 28,449 connections, in a memory that is 281,604 bytes in size. Try exploring around the space; please let me know if you find anything odd. :)  You can watch a sample exploration session, too:

Naiad says hello

Posted in Naiad with tags on 26 January 2011 by Craig Latta

Phew. I have Naiad (Spoon’s change management system) running in a small headless memory which is using another small headless memory as its edit history. I call the first one the “subject” memory, and the second one the “history” memory. I’m browsing the subject memory from a kitchen-sink memory that has Naiad support. I can install class and method editions into the subject memory from the browsing memory, and the subject memory keeps track of edits in the history memory, all without referring to class names. Naiad finally works! Yay!

Eventually, the headless subject memory will be the basis of a new distribution of Squeak… one where there is no bloat, everything is organized sanely, and everything is documented. :)

We can port the Naiad support to other memories (other versions of Squeak, and other Smalltalks). So, for example, one will be able to browse a Pharo memory from a VisualWorks memory and vice-versa.

Right now I’m doing another manual removal pass through the headless subject memory, using visualization data from the simulator as my guide.

This is fun!

Its only purpose is to show the appearance of this site. Thank you and good night.
