Travis-CI submodules

.travis.yml

# Use https (public access) instead of git for git-submodules. This modifies only Travis-CI behavior!

# disable the default submodule logic
git:
  submodules: false

# use sed to replace the SSH URL with the public URL, then init and update submodules
before_install:
  - sed -i 's/git@github.com:/https:\/\/github.com\//' .gitmodules
  - git submodule update --init --recursive

You'd better directly use https in your .gitmodules instead

@empeje but then you force every collaborator on the project to authenticate with username/password when checking out the submodules, no?

Hi @kytwb, it is a long time since I comment to this .travis.yml. I was a stubborn boy back then and didn't give any context when I put a comment.

It is a long time since I use submodules, I didn't have the answer.

No worries, genuinely curious. I had to implement that hack as well on one of my opensource repository.

I think I remember

use sed to replace the SSH URL with the public URL, then init and update submodules

before_install:
 - sed -i 's/git@github.com:/https:\/\/github.com\//' .gitmodules
 - git submodule update --init --recursive

I think I advice the author of this gist to directly using https instead of replacing it from git url to https url. GitHub has deploy key that you can use for individual repository to do some hack for the CI. Then I guess you can leverage Travis encryption to have the key committed to the repository safely on the public. Hope it helps.
