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@github.com: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

I have question regarding BaselineOf. If my package is depending on the Zinc-HTTP package, would the following baseline work for Pharo3 (which already includes Zinc)? baseline: spec <baseline> spec package: 'HttpExplorer' with: [spec requires: 'Zinc-Http']; yourself. Or is something like the following required in addition to make the configuration complete: spec project: 'Zinc-Http' with: [ spec repository: 'http://mc.stfx.eu/ZincHTTPComponents'; loads: #('Core'); version: #stable ].

thanks for your advice. This does mean that I should include the "spec project: 'Zinc-Http' with: [ ..." lines, correct? Thanks, Manfred

Yes, I think so, I have

project: 'ZincHTTPComponents' with: [ spec className: 'ConfigurationOfZincHTTPComponents'; repository: 'http://mc.stfx.eu/ZincHTTPComponents '; loads: #('Core' 'Tests' 'REST' 'AWS') ];

which groups you load it up to you, adding the version is OK I guess (I think it defaults to stable), I think the className is needed because of the odd casing.

But I can't say I am a Metacello expert ...

Sven, for not being a Metacello expert you did a good job. Just two things.

If you don't specify a verionString, the default is #bleedingEdge. If you want #stable, then it should be explicitly specified.

Secondly, your zinc spec (except for the versionString is correct. With the latest versions of Metacello, you can eliminate the need to specify a className by using configuration: or baseline: in place of project: like so:

configuration: 'ZincHTTPComponents' with: [ spec versionString: #stable; repository: 'http://mc.stfx.eu/ZincHTTPComponents'; loads: #('Core' 'Tests' 'REST' 'AWS') ];
