Hi all,
I have prepared an experimental kernel image based on Squeak 3.7.
Properties: - size: 1.3 MB - no Morphic - no MVC - no Sound - no Network - no Browser, Debugger etc. - no SUnit - no Projects support (there’s only one default project) - only necessary processes - no ObsoleteClasses (consistent references in sources) - single font - simple console with clipboard support - transcript output (with file log) - transparent creation mechanism
Download: - image with changes: ftp://comtalk.net/pub/bootstrap/kernel.zip - bootstrapping environment: ftp://comtalk.net/pub/bootstrap/Bootstrap.zip - please, can somebody place it to a new location with better connectivity?
How to prepare it: - use QuiteSmall image (http://www.swerlingphoto.com/squeak/QuiteSmall-3.7.zip) - load Mirrors.1.cs - load Bootstrap.st - evaluate "Bootstrap start" - in console type "Bootstrap revert" - wait a while - condense changes, clear transcript, save image
How it works: - for all classes in system "mirrors" are created. Mirrors are classes with prefix "Xxx" that contain only class definition and methods. They contain no valid references to class variables. - mirrors are modified so they contain whole class hierarchy for new system. There are original classes used in code of methods. - initial cleanup is executed and system processes are recreated - for all original classes, methods of mirrors are assigned. Methods that aren’t in mirrors are removed. Then the new definition of class is used. - unnecessary original classes are removed - mirrors are removed - whole sources are recompiled - additional cleanup is executed
The console is very simple. Now it cannot simulate FillInTheBlank, confirmations, user interrupt etc.
Feel free to clean, improve and fix this image. I have to say that I’m VERY tired of creation of this image now and I need a pause :-)
