Error loading own project from GitHub with Metacello

Manfred,

When you use github, you don't need nor do you want to use a ConfigurationOf. git manages the versions for you so you don't need to define versions in the ConfigurationOf. If you want versions for a git repository, use tags.

You still need to specify load order and project dependencies. For an example you can look at[1] or download the baseline:

Metacello new
  baseline: 'External';
  repository: 'github://dalehenrich/external:master/repository';
  get.

No need to specify a repository in the baselineOf, since the repository is derived from the location of the Baseline itself.

Hi,

sorry for the unfinished email upfront. I accidentially hit the send button before I was finished...

So here we go again:

Some time ago I started a small Pharo based project but didn't want to announce it before I knew how to load it conveniently.

For versioning I started using GitFileTree and pushed the code to GitHub together with a ConfigurationOf created with Versionner.

Only after a more recent email from Kilon on this list I figured out that the project should be easily loadable with the following commands:

Metacello new

configuration:'HttpExplorer';

repository:'github://mkroehnert/httpexplorer:master';

get.

Metacello new

configuration:'HttpExplorer';

repository:'github://mkroehnert/httpexplorer:master';

load.

Executing the first command succeeds and the ConfigurationOfHttpExplorer appears in the Browser.

But when I try to execute the load command I get the following error (unfortunately I don't yet know how to copy a complete stacktrace):

Error: Instances of UndefinedObject are not indexable

This is a result from executing ZnClient>>getConnectionAndExecute where 'request url' returns the following address:

http://:80/git@...:mkroehnert/httpexplorer.git/?C=M;O%3DD

I guess that the error is probably in the ConfigurationOf but I am a bit lost as to where I should dig further.

It would be great if anyone could point me in the right direction of where to look or tell what went wrong.

Thanks in advance,

Manfred

It is always better to depend on Zinc #stable since it still evolves while Pharo 3 does not.
