Hackage Matrix CI

This program is meant as a tool for suggesting version change of libraries. It tries to match official Package Versioning Policy.

See for details.

This version works by inspecting new/removed exported modules or entities. It doesn't currently check the types of exported elements.

Typical invocation:

package-vt module-ver-1.hs module-ver-2.hs

If you unpack modules with cabal unpack you can use the following form:

# unpack modules
cabal unpack package-1
cabal unpack package-2
package-vt module-1/module.cabal module-2/module.cabal
