Strategy for maintaining shared code between projects?

Question

I have about 5 or 6 projects that use "toolkit" code I've written. The problem I've came across is doing updates to toolkit code; when I do an update I usually need to apply these updates manually to the other projects.

Is there a common strategy for handling this kind of issue?

Answer 1

You can use git submodules.

Create a repository for your "toolkit" code and use it as a submodule for each of the other projects. To add a submodule, you can do:

$ git submodule add url_to_repository path_to_local_submodule

When cloning repositories with submodules, there are another steps required:

$ git submodule init and

$ git submoudule update

It will fetch the repositories that are submodules and checkout the appropriate commit of each.
