Version 1.0-beta.14 of Metacello was released this afternoon. Mostly fixes to bugs found while working with ConfigurationOfSeaside30: porting Seaside 3.0 to GLASS. Getting close to making Seaside 3.0 available on top of the GLASS 1.0-beta bootstrap (for both GemStone/S 64 2.3 and GemStone/S 64 2.32.4).

The rest of the details about the release can be found here.

It was just announced that the power to our Beaverton offices will be shutdown Friday afternoon for ’emergency’ power maintence between 1pm PST and 6pm PST.

I am looking into alternative hosting, but with such short notice, it isn’t likely that we will be able to move GemSource and the rest of the services hosted on If you were planning on downloading anything Friday afternoon, you’ll need to change your plans.


Not long after shipping the SOAP update for GLASS, I started working on Metacello. With the SOAP update, it became obvious that the GLASS ‘umbrella’ package was going to have to be replaced, and soon. Well, 7 months later I am reaching the point were I am finally ready to replace the GLASS package with a Metacello configuration .

I’m going to phase in the use of Metacello with GLASS. With the initial release, we’ll use Metacello for bootstrapping GLASS into a virgin extent. This way folks starting a greenfield project can use Seaside 2.8.4 or Pier 1.2 right away. Other releases that are in the pipeline:

  • GemStone/S 64 2.4.x with partial continuations for Seaside3.0.
  • Metacello configuration for bootstrapping Seaside 3.0 (ConfigurationOfSeaside30). A Squeak/Pharo version of this configuration is available now.
  • final release of GLASS.230 package that will boot Metacello into an existing GLASS installation and allow for upgrading to GLASS 1.0-beta.0 and beyond.

GLASS 1.0-beta.0

ConfigurationOfGLASS version 1.0-beta.0 is based upon GLASS.230-dkh.231, with the following additions:

  • Seaside 2.8.4
  • Pier 1.2
  • Metacello support
  • VB-Regex loaded as part of ‘core’
  • Scriptaculous updates from Ken Treis
  • GemTools updates from Gerhard Obermann
    • optional auto abort performed before commands
    • add remove method (without any checks) renamed “remove method …” to “safe remove method …”
    • add command “browse class history”
    • add class history index to class browser title
  • browse changes fixed … reversed comparison direction so that ”Install” will install repository version. the strike-out text is what is in current image.
  • supports bootstrapping of code into virgin extent (see Bootstrapping Instructions).

Read the following sections to gain an understanding of the 1.0-beta configuration structure. If you are impatient and just want to load and go, then you can skip to the Bootstrapping Instructions.

1.0-beta Configuration Structure

With release 1.0-beta.0 there are 9 different loadable configurations defined in ConfigurationOfGLASS. If you read the code in the method ConfigurationOfGlass>>baseline10beta00:, you can see the Metacello specification summarized in the following sections.

Primary GLASS Projects

Any one (or combination) of the following projects and groups may be used as a load configuration for bootstrapping

Each of these projects is managed by it’s own ConfigurationOfxxx class.

  • Core project. ConfigurationOfGsCore manages the Core, Base-Bootstrap, Bootstrap, GemStone-Exceptions (2.x only), GemStone-Indexing-Extensions, GsRandom, Sport, Squeak and VB-Regex packages. The Core packages are fundamental to the operation of GLASS and is always loaded.
  • FastCGI project. ConfigurationOfGsFastCGI manages the FastCGIPool and FastCGI packages. The FastCGI packages are optional and are used to support FastCGI packages for Seaside2.8 and Seaside3.0.
  • Hyper project. ConfigurationOfGsHyper manages the OpenSkills and Hyper packages. The Hyper packages are optional and are used to support the Hyper packages for Seaside2.8 and Seaside3.0.
  • Magritte project. ConfigurationOfGsMagritte manages the Magritte-Model, Magritte-Tests and Magritte-Seaside packages. The Magritte packages are optional and represent the GemStone/S port of Magritte. By default only Magritte-Model and Magritte-Tests packages are loaded. To load Magritte-Seaside, it must be explicitly referenced.
  • Metacello project. ConfigurationOfMetacello manages the Metacello packages and is imported from the Metacello project. By default the Metacello-Core, Metacello-MC and Metacello-Platform packages are loaded. The Metacello packages are fundamental to the operation of GLASS.
  • Misc project. ConfigurationOfGsMisc manages the MockGemStone, SMTPMail, Utf8Encoding, Announcements, XML-Parser, SIXX, SmaCC, System-Digital-Signatures, and GemStone-Release-Support packages. The Misc packages are represent useful pieces of functionality that are contained in a single package and depend only upon the Core project. The Misc project is rarely loaded in it’s entirety. Typically individual packages are loaded from the project.
  • Monticello project. ConfigurationOfGsMonticello manages the Change-Notification, PackageInfo-Base, and Monticello packages. The Monticello packages are fundamental to the operation of GLASS.
  • OB project. ConfigurationOfGsOB manages the OmniBrower, OB-GemStone-Platfrom, OB-Monticello, OB-SUnitIntegration, OB-SUnitGUI, OB-Stanadard, OB-Tools and JadeServer packages. The OB packages are optional and provide the implementation for the GemTools.
  • Pier project. ConfigurationOfGSPier manages the Pier-Model, Pier-Blog, Pier-DesignChooser, Pier-Design, Pier-Documents, Pier-EditorEnh, Pier-Google, Pier-Links, Pier-Randomizer, Pier-Slideshow, Pier-TagCloud, and Pier-Twitter packages. The Pier packages are optional and represent the GemStone/S port of Pier.
  • Scaffolding project. ConfigurationOfGsScaffolding manages the GemStone-Scaffolding package. The Scaffolding packages are optional and representing the implementation of Scaffolding for GemStone. Even though this project consists of a single primary package, the fact that it depends upon Magritte and Scriptaculous warrants the creation of separate Metacello configuration.
  • Seaside2.8 project. ConfigurationOfGsSeaside28 manages the Seaside2.8, SeasideAsync, Scriptaculous, RSRSS2, CallDemo, CheckboxExample, CSSDock, ErrorHandler, HelloWorld, ImageDemo, LogoutDemo, MarqueeDemo, menuDemo, ScreenResolution, Store, GemStone-Store, GemStone-Examples, FastCGISeaside and HyperSeaside packages. The Seaside2.8 packages are optional and represent the GemStone/S port of Seaside. By default only the Seaside2.8 pacakge is loaded. All of the other packages must be explicitly referenced.
  • Seaside2.8 Testing project. ConfigurationOfGsSeasideTesting28 manages the SeasideTesting and PierTesting packages.
  • SOAP project. ConfigurationOfGsSoap manages the SoXML, SOAP-CORE, SOAP-Client SOAP-Server, SOAP-Example and SOAP-TestCases packages. The SOAP packages are optional and represent the GemStone/S port of SoapCore.

Convenience GLASS Projects


The following groups have been defined for the common load configurations.

As you become familiar with Metacello and the GLASS configurations, you can define your load configuration. although you probably want to become more familiar with Metacello first.

Bootstrapping Instructions

Please comment to this post or send mail to the GLASS Beta Mailing List if you have trouble or the instrcutions are not clear. The bootstrap should work for the appliance or any version of GemStone/S 2.3 or greater.

  1. Start a stone using a virgin extent copied from $GEMSTONE/bin/extent0.dbf into $GEMSTONE/seaside/data. Don’t forget to shut the stone down before copying extents around and don’t forget to make the extent writable using ‘chmod +w extent0.dbf’.
  2. Download and unzip
  3. cd to the bootstrap_1.0-beta.0 directory
  4. Edit the .topazini file to match your stone.
  5. Launch topaz: ‘topaz -l -T50000’
  6. ‘login’ and ‘input installMaster.topaz’
  7. Exit topaz. The ‘installMaster.topaz’ script installs the Dev Group which includes the GemTools.
  8. Launch a GemTools Client 1.0-beta.1 image and login.
  9. [Updated: later that day] Due to some bugs discovered in 1.0-beta.0, it is recommended that you update to 1.0-beta.1 by executing the following expression:
    ConfigurationOfGLASS project updateProject.
    (ConfigurationOfGLASS project version: '1.0-beta.1')
        load: 'Dev'.
    System commitTransaction.
  10. Choose a configuration to load by executing one of the following expressions:
    (ConfigurationOfGLASS project version: '1.0-beta.1')
        load: 'Magritte Dev'.
    (ConfigurationOfGLASS project version: '1.0-beta.1')
        load: 'SOAP Dev'.
    (ConfigurationOfGLASS project version: '1.0-beta.1')
        load: 'Seaside Dev'.
    (ConfigurationOfGLASS project version: '1.0-beta.1')
        load: 'Seaside Testing Dev'.
    (ConfigurationOfGLASS project version: '1.0-beta.1')
        load: 'Scaffolding Dev'.
    (ConfigurationOfGLASS project version: '1.0-beta.1')
        load: 'Pier Dev'.
    (ConfigurationOfGLASS project version: '1.0-beta.1')
        load: 'Pier Testing Dev'.
    (ConfigurationOfGLASS project version: '1.0-beta.1')
        load: 'ALL'.
  11. Make a backup and have fun!

With the 1.0-beta.1 release of the GemTools Client, we’re doing two things:

  1. Conforming to the new Metacello configuration naming convention.
  2. Getting ready for the imminent GLASS 1.0-beta.0 release.

GemTools 1.0-beta.1 features:

  • Convert to using ConfigurationOfGemTools.
  • Nicer info dialog when Undefined symbols and Unsent messages are clean
  • Support for GemStone/S 3.0 GciErrSType
  • Change restore from backup done message … do not prompt to start Seaside gems if Seaside is not installed
  • Replace dialogs that are calling “ifNotEmpty:” with: “isEmptyOrNil” (from Gerhard)
  • autoAbort _before_ commands is now optional (off by default)

If you’ve already installed the GemTools Client 1.0-beta.0, then you want to follow the Update instructions. To install the GemTools Client in a virgin Squeak or Pharo image jump to the Install instructions.


With GemTools Client 1.0-beta.0 already installed, we need to update to using ConfigurationOfMetacello as well as ConfigurationOfGemTools:

  1. Load the latest version of the ConfigurationOfMetacello package  from
  2. Load the latest version of the ConfigurationOfGemTools package  from
  3. Execute the following expression in a workspace:
    ConfigurationOfMetacello loadLatestVersion.
    ConfigurationOfGemTools loadLatestVersion.

Then continue with Step 3 of the installation instructions.


If you haven’t already been using the GemTools 2.3.1 Preview for all platforms (which is based on Pharo), then you should download the preview GemTools client and follow the instructions for setting up your session to verify that you can connect to your stone. You’ll need the session information and the gci files from the Preview to get things running with the either Squeak or Pharo.

I’ve tested the installation procedure using Squeak3.10.2-Trunk-090912 and pharo1.0-10492-rc1dev09.11.1.

To load GemTools into a client image:

  1. Load the latest version of the ConfigurationOfGemTools package  from
  2. Execute the following expression in a workspace:
    ConfigurationOfGemTools loadLatestVersion.
  3. Execute the following expression to open the GemTools launcher:
    OGLauncher open
  4. Copy the session information from your old GemTools Client to the new GemTools Client in your image. Use the Edit session menu item on the Session Menu in the launchers.
  5. Save the image.
  6. Copy the gci files (gciForWindows.dll,, and from in the one-click into the directory containing your image and changes files. On the Macintosh, the needs to be copied to both the image directory and the directory (thanks Mark and Ken).
  7. Press the Login button on the GemTools Launcher and you should be in business.

I just released version 1.0-beta.12 of Metacello this afternoon.

New Configuration class and package naming convention: ConfigurationOfxxx

The most significant change is that I’ve renamed the configuration class and Monticello package to ConfigurationOfMetacello. This is a naming convention that Tudor Girba started using for the Moose project naming the Metacello configuration class and package: ConfigurationOfMoose. If the naming convention is used all of the Metacello configurations are put in close proximity in the Class Browser (when sorted alphabetically) and the Monticello Browser, so configuration classes and packages are easy to find. It also makes it easy to recognize that Metacello is being used for a project. I am in the process of converting all of the Metacello configurations that I’m managing to use this convention.

If you’ve started a Metacello configuration you should start using the naming convention, just rename the class, and save it in a new package. Your version meta data (the important stuff) is preserved. Also don’t forget to update your class-side #ensureMetacello method to use ConfigurationOfMetacello (see the class MetacelloConfigTemplate for an up-to-date example).

ConfigurationOfMetacello available on SqueakSource

In addition to publishing the Metacello configuration on GemSource in the Metacello project, I’ve published the configuration on SqueakSource in the Metacello project to make it easier to find. The primary source repository remains on GemSource.

Load Project Version improved

The Load Project Version command was also changed with this release. The list of versions has been shortened and the current version is marked with an ‘*‘. Finally instead of loading ‘ALL’, the list of packages used the last time that the project was loaded is used. If no previous information has been recorded then the ‘default’ group is loaded. By default the previous version is not recorded. You can implement two class-side methods on your configuration to record the information (#lastMetacelloVersionLoad and #metacelloVersion:loads:. See the class MetacelloConfigTemplate for an example).

The rest of the details about the release can be found here.

If you’re curious, install Metacello into your image and take the tutorial!
