question about repositoryOverrides:

Hi Dale. I am trying to understand repositoryOverrides: and I come to two questions that you may help me.

All the examples I saw for repositoryOverrides: are done from a workspace, to load a version. Example:

| localRepository version |
localRepository :=


    MCDirectoryRepository new
        directory: (FileDirectory on: '/home/dhenrich/monticello').


version := ConfigurationOfMagritte project version: '1.2.1.3'.
"set the repositoryOverrides"


version repositoryOverrides: (Array with: localRepository).


"do the load" 
version load.

or:

| project version repo |
project := self project.
version := project version: '1.0'.
repo := MCDiDirectoryRepository new.
repo directory: FileDirectory on: '<path to directory>'.
version repositoryOverrides: (OrderedCollection with: repo).
version load.

Now...this is only done from a workspace, but can I do this with a project reference? Suppose the above code loads ConfigurationOfPharo. Ok, that mcz (ConfigurationOfPharo) will be download from the localRepository instead of MetacelloRepository. But, what happens with:

a) the repositories I have specified in self repository: of ConfigurationOfPharo
b) the repositories I have specified in a project reference. Example:

project: 'Shout'
                    with:
                        [ spec
                                className: 'ConfigurationOfShout';
                                loads: #('Core');
                                file: 'ConfigurationOfShout';
                                repository: 'http://www.squeaksource.com/MetacelloRepository' ];

c) the repositories i have specified for a particular package:
Example:

spec
                package: 'RoelTyper' with: [ spec repository: 'http://www.squeaksource.com/RoelTyper' ];


So...my question is...what does really overrerides that method?   which repositories?

Thanks

Re: question about repositoryOverrides:

Mariano,

#repositoryOverrides: is a message that you send to a version ... once
you've specified a repositoryOverride: the override carries over for all
loads that originate from the original load, so _all_ repositories
version, package, and project reference repositories.

#repositoryOverrides: is useful in the scenario where you have fetched
_all_ of the mcz files that you are using in your application and
stashed them in a local repository and then want to load using that
repository.
