This repository contains a sources.txt file in the format expected by
cabal-meta. This allows you to build
and develop the most recent HEAD versions of the toy packages.
git clone https://github.com/mgsloan/toy-sources.git
cd toy-sources
cabal-meta install
If all goes well, the HEAD versions of the toys packages will now be in the
vendor/ directory, and be installed to your local cabal package database.
One possible source for build failure might be if these libraries depend on the HEAD versions of diagrams packages. While currently they build with the hackage version of the diagrams packages (0.7), at some point in the future this might not be the case. If so, an easy way to install the HEAD versions of the diagrams packages is to use diagrams-sources.
