Re: [Pharo-users] Git overriding repo load from different source
I'm not sure how to answer all those cases Those were just options that came to my mind how to solve it - practically just one is needed. (did I remember a conversation during PharoDays?). We spoke only very briefly about something else since I didn't use Git at the time yet. Can you elaborate on a) and the failure? Because I remember looking at the ability to override conflicts in Metacello by just saying: onConflict: [:ex | ex allow ] Yes, onConflict: solves the overriding issue, thanks! Peter

I'd recommend that you not put in the unconditional onConflict: ... at one point in time the onConflict: was required to handle locks, but currently the default handler for onConflict: will honor locks and the default handler for onLock: will dump signal a Warning and then honor the lock. Putting in onLock: as you've done _is_ a good way to bypass the onLock: Warnings ... you can use `honor` instead of `disallow` and `break` instead of `allow` for the onLock: notification as those messages read a bit better ... The interesting onConflict: notifications occur when an incoming project decides to change the version or repository or configuration type (BaselineOf or ConfigurationOf) ... so if you care to know when this type of thing happens, then you can _leave off the onConflict:_ and you'll get a chance to decide if you want to have that change made to your system, before it is loaded rather than discover the change after it is loaded ... this is basically why I added the onLock: message - so that you weren't tempted to add an uncoditional onConflict: block just because you were working with locks:) Dale
Re: [Pharo-users] Git overriding repo load from different source
Peter, sorry for not answering sooner ... I keep an eye out for posts with Metacello in the subject line so I missed this one ... So if i understand your question, you have a GitHub project that you normally download like this: Metacello new baseline: 'Sample'; repository: 'github://GsDevKit/sampleProject:master/repository'; load. now you have cloned the repository to a local git repository: cd /opt/git git clone g...@github.com:GsDevKit/sampleProject.git and you can directly load the project like this: Metacello new baseline: 'Sample'; repository: 'filetree:'///opt/git/sampleProject/repository'; load. but in another configuration (that you may not control) there is dependency upon Sample that looks like this: spec baseline: 'Sample' with: [ spec repository: 'github://GsDevKit/sampleProject:master/repository' ]. and you are wondering how you can force you local clone to be used ... is that correct? If so then the trick is to use the Metacello `lock` ... Do the following BEFORE loading the project that depends upon you sample project: Metacello new baseline: 'Sample'; repository: 'filetree:'///opt/git/sampleProject/repository'; lock. Then whenever Metacello finds a dependency upon 'Sample' the local clone (the `lock`ed) project will be used instead. This is use case is the primary reason for the existence of the `lock` command. Also note that you need to use the scripting api for all loads to make sure that the lock is honored. Finally you can use the onLock: message to break the lock in certain cases ... the default Metacello load honors all locks (a Warning is dumped to the transcript) ... As Thierry mentions, you should be using the latest version of Metacello on github ... If I missed the mark here let know ...

Re: [Pharo-users] Git overriding repo load from different source
d) unload all B packages, remove B github repo, load B locally However currently I can only unload packages one at a time manually, instead of all related to a repo. Peter
Re: [Pharo-users] Git overriding repo load from different source
e) having separate baseline method which does not load github packages and expects that they are already loaded But since baseline only uses single method I don't see how this could be done.
