Merge multiple repositories into one big monorepository. Migrates every branch in every subrepo to the eponymous branch in the monorepo, with all files (including in the history) rewritten to live under a subdirectory.
Prepare a list of repositories to merge in a file, for example repos.txt:
git@github.com:mycompany/service-one.git one
git@github.com:mycompany/service-two.git two
git@github.com:mycompany/service-three.git three
The format is: <repository_url><space><new_name>. The repository url can be
anything that can be passed to git clone.
Now pipe the file to the tomono.sh script. Assuming you've downloaded this program to your home directory, for example, you can do:
$ cat repos.txt | ~/tomono/tomono.shThis will create a new repository called core, in your current directory.
If you already have a repository called core and wish to import more into it,
pass the --continue flag. Make sure you don't have any outstanding changes!
The contents of each repository will be moved to a subdirectory. A new branch will be created for each branch in each of those repositories, and branches of equal name will be merged.
In the example above, if both repositories one and two had a branch called
feature-XXX, your new repository (core) would have one branch called
feature-XXX with two directories in it: one/ and two/.
Usually, every repository will have at least a branch called master, so your
new monorepo will have a branch called master with a subdirectory for each
original repository's master branch.
