Attempting to move Cog to Git(Hub)

 

and I forget to mention that I’m highly excited with the idea of moving the development to git/github :)

thank you very much for this, Fabio!

Hi all,

I've been playing around with Cog to see what it'd take to move the code to git.

GitHub's svn importer [1] isn't very reliable I think (some directories were actually

missing), but eventually I managed to convert the entire svn repo to git [2].

Also, I have been able to build different Cog VMs automatically on Travis CI.

yes, we are doing this since some time… one of the many advantages of being in git/github. 

(we also run pharo tests so we can "more or less” test the vm automatically.

 

For a working build, see [3]. You can download the results at [4]. Please keep

in mind that this is still a "test" ;)

Eliot was also concerned how the version info will be maintained and I have a

simple proposal:

Each Cog release will be a git tag and for the version itself we could use

semantic versioning [3]. Then the build version is the git tag, the date is the

commit date and the URL is the "remote.origin.url”.

+1

(but I think Eliot was concerned on the history already present in svn… for that, there are tools that migrate svn to git with all history, something like this: http://john.albin.net/git/convert-subversion-to-git)

Here's an example:

Any further suggestions? :)

“squeak” is a bad name :)

“cog-vm”, “squeak-vm” (anything with “vm”, in fact) would be better :)

Best,

Fabio

cheers!
