Hello Ralph,

My usual source for documentation about Metacello is https://github.com/Metacello/metacello/ and the links given in the readme file there.

The help pages on Metacello with the "Getting started" page seem to be outdated. I do not know in which particular state its Tutorial package is, but since the last commit is from 2012 chances are not bad that it is outdated, too. https://github.com/Metacello/metacello/commits/master/repository/Metacello-T...

In your latest reply that went into a new thread, you wrote that Metacello was already loaded in your image. But a plain Squeak 6.0 image does not have Metacello loaded from the start. It only has a stub that loads Metacello when first used.

The customary way to load Metacello since Squeak 5.2 has been `Installer ensureRecentMetacello`. You do not need to deal with ConfigurationOfMetacello by yourself.

Kind regards, Jakob

I have downloaded Squeak 6.0 and figured it was time I learned to use Metacello so I could learn to load all packages for my project at once.

Reading the documentation on Metacello at Metacello>>getting started it stated: " If you have a porject [[correct spelling is: project]] that you'd like to use Metacello with, you should start by taking the Metacello tutorial to familiar [[note familiarize/familarise is the correct word here depending on whether you use British or American spelling]] yourself with the configuration specification language. First load the tutorial code:

ConfigurationOfMetacello project latestVersion load: #('Tutorial').

".

But this class did not exist in my image. From the Internet I found the command: " Installer gemsource project: 'metacello'; install: 'ConfigurationOfMetacello'. "

This was for Squeak 4.3 so I didn't know if it would work but I gave it a try and it seemed to work.

This put class ConfigurationOfMetacello in my image.

I again ran: ConfigurationOfMetacello project latestVersion load: #('Tutorial').

This gave me the warning: " You are about to load new versions of the following packages that have unsaved changes in the image. If you continue, you will lose these changes.

Metacello-Core "

Here I ignored the warning and clicked on <proceed>. Now I get the error: " MCHttpRepository(Object)>>doesNotUnderstand: #repositoryDescription "

So where do I go from here? How do I download this tutorial or is there a better place to learn about Metacello for the purpose of being able to load all the packages I've written for a project all at once?

Thanks for any guidance.
