By the way, at the recent Sage Days in Bonn, I learnt how to host the package repository at github and use Travis CI to some extent. I have posted the link to the ticket description.
Note, however, that testing it on Travis CI with python-3 will be difficult: I was told that the current Sage-with-py3 docker image is rather outdated, and also I don't know how I should write my .travis.yml
so that the automatic tests involve both py2 and py3. The answer on sage-devel didn't help me much. Is someone reading this who can tell me how I should modify .travis.yml
?
