For example, you can do a git remote --verbose
and git will show all the remotes you have on your project, git branch
will show all the branches and signal the current branch, but how to list all subtrees, without any destructive command? git subtree
will give the usage examples, but won't list anything. subtree only have add
,pull
,push
,split
,merge
.
Specify the prefix local directory into which you want to pull the subtree. Specify the remote repository URL [of the subtree being pulled in] Specify the remote branch [of the subtree being pulled in] Specify you want to squash all the remote repository's [the subtree's] logs.
git subtree lets you nest one repository inside another as a sub-directory. It is one of several ways Git projects can manage project dependencies. Why you may want to consider git subtree. Management of a simple workflow is easy.
git subtree split lets you specify a rev other than HEAD. ' git push '(man) lets you specify a mapping between a local thing and a remot ref. So smash those together, and have git subtree push let you specify which local thing to run split on and push the result of that split to the remote ref.
There isn't any explicit way to do that (at least, for now), the only available commands are listed here (as you noted yourself, but here's a reference for future seekers): https://github.com/git/git/blob/master/contrib/subtree/git-subtree.txt
I went through the code (basically all this mechanism is a big shell script file), all of the tracking is done through commit messages, so all the functions use git log
mechanism with lots of grep
-ing to locate it's own data.
Since subtree must have a folder with the same name in the root folder of the repository, you can run this to get the info you want (in Bash shell):
git log | grep git-subtree-dir | tr -d ' ' | cut -d ":" -f2 | sort | uniq
Now, this doesn't check whether the folder exist or not (you may delete it and the subtree mechanism won't know), so here's how you can list only the existing subtrees, this will work in any folder in the repository:
git log | grep git-subtree-dir | tr -d ' ' | cut -d ":" -f2 | sort | uniq | xargs -I {} bash -c 'if [ -d $(git rev-parse --show-toplevel)/{} ] ; then echo {}; fi'
If you're really up to it, propose it to Git guys to include in next versions:)
