It's okay if the quotes get long, because long messages are manageable, but messages that require you to look at *other* messages at the same time are just a PITA.

In that case, it does do exactly what cvs export and svn export do, so I take it back. I would never use it (because I always deploy my .git directories along with the app itself... free backups!).

Is it okay to have "/" characters in the ini section name? Yes. In general, a section name can have anything except a ] in it, and a key can have anything but an = in it. (Well, obviously we should expect that there are no CR, LF, or NUL characters either.) If you want to do it exactly like git, you would name your sections like [ext "libs/my/plugin"] instead of my earlier suggestion of [libs/my/plugin] This would be compatible with git-config. Also, this method means that the [main] section could never be confused with a particular ext section. > I wonder if it would be okay to just put the repository > as the section name.

I think you answered your own question there :) Personally, it feels natural to me to index a submodule by its local path, and have the URL be an attribute of that submodule, rather than the other way around. This makes sense since every local path can only have one submodule on it, while in insane situations, you can imagine having exactly the same repo (perhaps different revisions or branches?) cloned into two different locations. > But yeah, if this feature makes somebody nervous, they can just always > explicitly give the path (which they'll have to do if it's not a rails > app.) It also detects that it's a rails app so it will complain if > you leave the path off in a non-rails app. It won't try to put > something in vendor/plugins of a non-rails app just because a path is > missing. Okay, if it's not in rails mode, I guess it won't cause problems... as long as the rails auto-detection is extremely reliable and can be turned off somehow. > 5. Yeah that's a good idea.

Right, it wouldn't matter which way you did it, but the other options below fit really nicely into a 'git save' operation. Also, I personally think it's more elegant to not have to do "undo" operations as a normal part of your workflow. Checkout work work work save seems nicer to me than Checkout uninstall work work work. [nested submodules] > 6. Hey that's a pretty interesting idea!

Ouch, I would never want to do it that way! If my app has been deployed for three months and someone reports a minor bug, I just want to fix that one bug and redeploy safely and immediately. I certainly don't want to risk breaking everything by upgrading a bunch of unrelated modules. > the way I > currently have been handling this is by having my own rails repository > at git://github.com/azimux/rails.git that I occaisionally will merge > rails/rails.git with and run tests for my larger applications.

This sounds like a convoluted way of just doing what I suggested. :) Oh, that reminds me of another feature that would be awesome: *alternate* repository URLs. In your example above, let's say you've made some rails customizations, anyone cloning your project will have to get your version. But one day, the rails developers merge in your changes, so now their primary repo (probably with more bandwidth, uptime, etc) will work again. If the ext lists *all* the repositories you might need, ext can just git fetch from all of them, then checkout the commit in question, and it will always work. > And I would definitely not > have it disconnected from a branch if it can be avoided.

It can be simpler than that. Essentially, what you do is: git fetch origin git checkout COMMITID git branch -D BRANCHNAME git checkout -b BRANCHNAME The first checkout puts you on a disconnected HEAD temporarily, just in case you were previously on a branch called BRANCHNAME, which would have prevented the "delete branch" operation from working. Then we delete the branch, and recreate it at the new location (COMMITID). With that in place, git will know how to do everything else automatically, but it's up to the user. You can pull/merge the latest changes from another branch, or rebase, etc. Note that as a safety measure, you probably want to refuse to actually do the above if either of: a) The git filesystem or index shows uncommitted files b) The current git commit != the commit ext thinks is checked out right now. > 9.

I think it would be really cool if ext could just figure this out. For example, it's easy to tell that in svn, your changes have to be committed (ie. no dirty tree) and in git, the upstream repo needs to contain your commitid (it's been pushed). If you only want to push a subset of projects, that's fine, but you can do it in the individual subdirs by hand anyhow. On the other hand, I'd say you *don't* want to ever push the parent repo without first pushing all your changes, particularly if you have the commitid encoded in the .externals file, or you'll produce an un-checkout-able repository. > Maybe what I could do is have "ext status" also see if a subproject > could be pushed and issue a warning like "<subproject> has commits > that are missing from <remote name>.

I don't think it should do nothing for svn/cvs projects: it should either help you commit, or abort with a helpful message if your repo is dirty, or something like that. Hope this helps.
