pkg is a simple, minimal dependency manager based on Git.

It clones your cycle-free dependency tree recursively and creates a CMakeLists.txt file with all dependencies in topological order.

Example .pkg file:

[fmt]
  url=git@github.com:motis-project/fmt.git
  branch=master
  commit=3eca62d66c7c9a2ca97dc8381299d911978b9fb2

Useful commands

After invoking CMake, the pkg binary executable can be found in build/dl/.

Displaying the dependency tree

pkg -s

Syncing deps/

After updating a commit ID in the .pkg file, you can pkg -l to establish the dependency tree state described in the .pkg file. Effectively, git repositories will be updated in deps/.

You can use -f to force checkout the commits.

Warning

This will override the changes you made, so be careful.
