submods-to-source-repos

Convert a submodule-using cabal.project file to one that uses source-repository-packages.

Instructions

1. First, clone the repository with submodules that you are interested in:

   $ git clone <repo> && cd <repo-dir> && git submodule update --init --depth 1
   

   The git submodule update --init --depth 1 part is necessary because submods-to-source-repos must look into the contents of each submodule to determine where each submodule's .cabal files are located. However, this does not require the full git history of each submodule, so you can save some time by cloning each submodule shallowly with --depth 1.

2. Invoke submods-to-source-repos on the main cabal.project file:

   $ submods-to-source-repos cabal.project
   

   If you want to save this as a new cabal.project file, you can redirect the output like so:

   $ submods-to-source-repos cabal.project > cabal.project.new
