All print function need get a parameter ostream

[Tal Regev]

All print function need get a parameter ostream. For easy print to file or other ostream like string stream.

If not give parameter of ostream, it will use std::cout. (default parameter).

I'm thinking it might be better to have stream operators for every class and then reduce print as calling output on stdout (and maybe even retire it). Comments?

[Tal Regev]

I thinks this solution is also good. Can you do it for gtsam 3.2.0?

[Frank Dellaert]

GTSAM Is an open source project. If you want to add some functionality, you can fork and create a pull request. It might be good to think about how to do this so we can cherry pick the changes into develop as well.

Thanks for the feature request. We would like to see this feature soon as well and will probably be a part of GTSAM 5.

[Tal Regev]

Why not fix?

Why not added to gtsam3 and gtsam4?

[Frank Dellaert]

Actually, the feature I'd like to see is just a stream output operator that replaces print, as of GTSAM 5. That could be added now, if you want. Since GTSAM is open source, you could create a PR for a few of the basic types as a design review, and then complete the PR for all types after comments.
