Configuring Metacello with github on Squeak
 
|
Hello, This is my first post, I'm a total newbie to Squeak but so far I'm finding it very interesting. I have to develop an academic project with a classmate and so far I've used Squeak alone by my own without sharing anything so this new requirements raised some questions. I managed to use Montecello fine but It seems to do a version control like on packed files (like a jar, doing a Java analogy). I thought of using Montecello over Dropbox with my friend. Is this solution reliable / recommended? For me it seems more intuitive using git versioning over code files instead of packed files. To accomplish that I've read something about Metacello, but the Squeak installation seems *very* confusing to me. I managed to create a filetree repository but I don't know how to link it to my git repo: https://github.com/poo2013pos/FLOdactic with the spec file and how to proceed then (over Squeak or over the console with the git command). I've read both manuals of Metacello, the one on Github and the one on Google Code but no luck so far. Can anyone please help me with this?

Albert,

Metacello is still in the process of being adopted by Squeak and Pharo (Pharo2.0 is the first release with Metacello pre-loaded) so you're experiencing a bit of the early adopter pain:) ...

Can anyone please help me with this? | Ah yes, I guess there is a hole in the documentation there... First you need to clone your github repository to your local drive: git clone https://github.com/poo2013pos/FLOdactic.git Then using the MonticelloBrowser, you create a filetree repository by selecting the FLOdactic folder that contains your cloned git repository. With the MonticelloBrowser, you can then simply load the packages manually using Gofer or Installer referencing the FileTree repository ... If you don't have a lot of packages or don't depend upon other projects this option should work pretty well (i.e., not using Metacello at all). You also use the MonticelloBrowse to save new versions of the file to your git repository, then you use the os command line to manually commit and push the contents of your repository using `git` commands... If you want to hook up the Metacello Preview, then you need to follow the directions here[1] to bootstrap the preview. Next you would want to create a BaselineOf for your project. I suggest that you look at the Sample repository[2] for inspiration and for you BaselineOfFLOdactic you should take a look at BaslineOfSample>>baseline method[3]. Basically you create the BaselineOfFLOdactic class, save it in the FLOdactic repository, then you can use the Metacello Scripting API (in the Metacello Preview release) to load your code with the following expression: Metacello new baseline: 'FLOdactic'; repository: 'filetree://<path to local FLOdactic git repository>'; load. The final step would be to create a ConfigurationOfFLOdactic and again you can look at the configuration branch of the Sample project[4] for inspiration. In this case you create sets of version* methods that look like ConfigurationOfSample>>version091:[5] ... The configuration references the BaselineOfSample so there's no need to create a baseline method when using Configurations with github repositories. Finally you can use the Metacello Scripting api to load your code directly from the github repository: Metacello new configuration: 'FLOdactic'; version: '1.0'; "or whatever" repository: 'github://poo2013pos/FLOdactic:configuration'; load. Note that when you load directly from the github, the repository is readonly ... the big missing piece for this scheme at the moment is git/image integration, so to you need to do manual git clone and filetree repository if you want to commit changes ...

Many thanks for your great and kind answer Dale!
Your post helped me a lot! I think I'm going to stuck to filetree and git right now until I gain some knowledge. So far it seems to work for my needs. Regards!
