looking for general opinions ... i am (frighteningly :-) teaching a git course later this week, and one of the topics on the list is git submodules, which was specifically requested by the client as their idea of how to start incorporating child repos in new projects.
however, given the number of articles written about the drawbacks with submodules, i wanted to throw in a section about "git subtree" as well, even though (as discussed earlier) there is some minor dispute as to whether "git subtree" is part of "core" git, but i'm not going to let that stop me. going even beyond that, there is also google's "repo" command, which i seem to see more and more often, like here for automotive grade linux: https://wiki.automotivelinux.org/agl-distro/source-code and it would be a shame to at least not mention that as yet another possibility. and then there are unofficial, hand-rolled solutions, like "git-subdir": https://github.com/andreyvit/git-subdir given that the client does not appear to be wedded to any particular solution yet, i'm open to recommendations or pointers to online comparisons that i'll collect and post on a single wiki page, and they can peruse the comparisons at their leisure. so ... thoughts? no need to be verbose, just links to decent online discussions/comparisons would be massively useful. rday p.s. oh, pointers to well-designed usage of any of the above would be handy as well. as i mentioned, for "repo", there's AGL. for submodules, i might use boost: https://github.com/boostorg/boost/wiki/Getting-Started and so on. thank you kindly.
