Kernel image

The KernelImage is a project that tries to radically improve modularization of Squeak Smalltalk images. Its goal is to create small independent kernel image that enables to load the rest of Squeak stuff from internet

The main current source of information is wiki on the SqueakSource page:

Kernel image description by Ralph Johnson
How to load Seaside and Scriptaculous

List of images

KernelImageMC
- basic version of the KernelImage, it includes basic primitive packages Kernel, Compression, Network, PackageInfo and Monticello
- enables to load next packages via Monticello
KernelImage
- the smallest version on the KernelImage, it includes only the package Kernel
- it's generated using this script from KernelImageMC: shrink.st
- basic primitive packages Compression, Network, PackageInfo and Monticello must be loaded using uncompressing of their Monticello packages and loding the source.st files manually.
KernelImage-Seaside
- Includes packages SUnit, GraphicsFiles, DigitalSignatures, DynamicBindings, KomServices, KomHttpServer, SeasideCompatibilityLayer, Seaside and Scriptaculous
- default user name: admin
- default password: seaside
- if you want to use WABrowser, you must load this (ugly and unclean) code: http://comtalk.cz/public/pub/KernelImage/Browser.st
MinimalMorphic
- includes basic primitive packages and MinimalMorphic package (+loader)
- small Morphic system without EToys
- loaded using MinimalMorphicLoader (see below)
EToys
- includes basic primitive packages, MinimalMorphic and EToys (+loaders)
- full Squeak version with the source codes that are almost the same as in case of final Squeak 3.9
- loaded using EToysLoader (see the KernelImage SqueakSource repository)

Information for Developers

Some of this information may be obsolete

KernelImage - MinimalMorphic overrides
Fully packaged KernelImage ([ANN])
bootstrap-7067.zip
shrinkScript-7067.zip
KernelImage-7067.zip
KernelImage-MC-7067.zip - KernelImage with primitive packages (7061c)
KernelImage-MC-Loader-7067.zip - KernelImage with preinstalled primitive packages (7061c) and MinimalMorphicLoader-boot.5.mcz

Shrinking Squeak 3.9 to the KernelImage

download latest skrinkScript (zip)
file in console.st
in the console evaluate: (FileStream readOnlyFileNamed: 'shrink.st') fileIn
save image: SmalltalkImage current snapshot: true andQuit: false

Minimal Morphic

for the latest MinimalMorphic system instalation take latest KernelImage with preistalled Monticello and evaluate this code:

((MCHttpRepository location: 'http://squeaksource.com/KernelImage'user: '' password: '') loadVersionFromFileNamed:'MinimalMorphicLoader-pk.24.mcz') load.

MinimalMorphicLoader load.

MinimalMorphicLoader-pk.xx.mcz is the name of the latest MinimalMorphicLoader version (check the SqueakSource repository)
the code in the console MUST be in the single line so you have to have wide Squeak window!

EToys package

load the latest EToysLoader into the MinimalMorphic system

Data files:

KernelImage Monticello repository

There's Monticello repository with pacakges for the KernelImage

http://www.squeaksource.com/KernelImage.html

Here you can find modified versions of standard packages.

You need to have KernelImage with Monticello support. That means that you should create basic KernelImage, then download latest versions of packages Compression, Network, PackageInfo and Monticello from the repository, unzip it end load source.st files of all this packages.

KernelImage-MC-7061c.zip

use external files for long scripts, current console cannot process multiline commands

You may then reload this packages from the repository again:

#('Compression-pk.10.mcz' 
  'Network-pk.41.mcz' 
  'PackageInfo-al.6.mcz' 
  'Monticello-pk.309.mcz') 
do: [:packageName | 
    ((MCHttpRepository location: 'http://www.squeaksource.com/KernelImage' user: '' password: '')
    loadVersionFromFileNamed: packageName) load ].
MCFileBasedRepository flushAllCaches.

Then you can load next packages like Comanche and Seaside.

#('SUnit-pk.35.mcz' 
  'GraphicsFiles-pk.3.mcz' 
  'DigitalSignatures-pk.3.mcz' 
  'DynamicBindings-gk.3.mcz' 
  'KomServices-pk.4.mcz' 
  'KomHttpServer-pk.2.mcz' 
  'Seaside2-pk.7.mcz') 
do: [:packageName | 
    ((MCHttpRepository location: 'http://www.squeaksource.com/KernelImage' user: '' password: '')
loadVersionFromFileNamed: packageName) load ]

Some other packages like Scriptaculous can be loaded from standard repositories.

((MCHttpRepository location: 'http://www.squeaksource.com/Seaside' user: '' password: '') loadVersionFromFileNamed: 'Scriptaculous-lr.141.mcz') load

How to save package:

| repository pkg |
repository := (MCHttpRepository location:
  'http://www.squeaksource.com/MyRepository' user: '' password: '').
pkg := MCPackage named: 'MyPackage'.
pkg workingCopy repositoryGroup addRepository: repository.
repository storeVersion: pkg workingCopy newVersion.

This Seaside package doesn't have Browser support but you may install Browser.st from http://www.comtalk.cz/Squeak/uploads/20/browser.zip and if you will evaluate
WABrowser class compile: 'canBeRoot ^ true'
you may create root Seaside application with WABrowser component.
You may want to use this code too: SystemOrganization removeEmptyCategories

The rest of this page contains mostly outdated information

Basic Morphic

Basic Morphic system without eToys:

basicMorphic001.zip
bacicMorphic002.zip - newest package for the KernelImage
Squeak3.9g-7061-basicMorphic.zip - prepared image based on bacicMorphic002

KernelImage Monticello repository

There's Monticello repository with pacakges for the KernelImage

http://www.squeaksource.com/KernelImage.html

KernelImage-MC-7061c.zip

use external files for long scripts, current console cannot process multiline commands

You may then reload this packages from the repository again:

#('Compression-pk.10.mcz' 
  'Network-pk.41.mcz' 
  'PackageInfo-al.6.mcz'

do: [:packageName | 
    ((MCHttpRepository location: 'http://www.squeaksource.com/KernelImage' user: '' password: '')
    loadVersionFromFileNamed: packageName) load ]

Then you can load next packages like Comanche and Seaside.

#('SUnit-pk.35.mcz'

pkg := MCPackage named: 'MyPackage'.

repository storeVersion: pkg workingCopy newVersion.

Shrinking script for 7061

shrink.zip
load console.st
in the console evaluate: (FileStream readOnlyFileNamed: 'shrink.st') fileIn
save image: SmalltalkImage current snapshot: true andQuit: false

Version 7061c

KernelImage-7061c.zip - prepared image
packages-7061c.zip - compression, network, package info, Monticello, SUnit
bootstrap-7061c.zip - self-bootstrapping environment

Packages are in the Monticello compressed format but (of course) there's no Monticello present in the image during the first load. So you have to decompress the packages and file-in source.st file.

Order

compression, network, packageinfo, monticello

[(FileStream readOnlyFileNamed: 'compression.st') fileIn] ifError: [:e | { e. thisContext stack first: 20 }].
[(FileStream readOnlyFileNamed: 'network.st') fileIn] ifError: [:e | { e. thisContext stack first: 20 }].
[(FileStream readOnlyFileNamed: 'packageinfo.st') fileIn] ifError: [:e | { e. thisContext stack first: 20 }].
[(FileStream readOnlyFileNamed: 'monticello.st') fileIn] ifError: [:e | { e. thisContext stack first: 20 }]

Save image

SmalltalkImage current snapshot: true andQuit: false

Save package

(MCPackage named: 'Monticello' ) workingCopy newVersion

Load package from a repository

[((MCHttpRepository location: 'http://squeaksource.com/DynamicBindings' user: '' password: '') loadVersionFromFileNamed: 'DynamicBindings-sam.2.mcz') load]ifError:[:e | { e. thisContext stack first: 20 }]

Note:

The console can process only one line command so you can write it into a script or make the display wide enough.
