Build Status Hackage


iridium is a fancy wrapper around cabal upload. It aims to automate several typical steps when releasing a new package version to hackage.

Iridium does all testing locally, in contrast to e.g. github's travis. This makes it easier to keep your published history free of commits that fail any tests (without squashing or separate branches).

Steps currently include:

  • Compilation and running tests using multiple compiler versions. (the different compilers must already be installed.)

  • Checking that the changelog mentions the latest version.

  • Checking that the upper bounds of dependencies are up-to-date by making use of stackage snapshots.

  • Uploading of both the package itself and the documentation.

The output on errors is certainly not optimal; for example the stackage upper bound checking will print a typical, hard-to-consume cabal error message. iridium's focus is on notifying if something is wrong.


Install iridium, run iridium in the directory containing the cabal package. It won't do anything without confirmation.

Test Description
hlint forM_ hs-source-dirs $ \dir -> (\dir -> call "hlint " ++ dir)
testsuites run cabal test when compiling.
upper-bounds-stackage Check that upper bounds are up-to-date by using a stackage cabal.config. This is not the best way, because not all packages are on stackage, but it is better than nothing.
lower-bounds-exist Check that all dependencies have a lower bound.
upper-bounds-exist Check that all dependencies have an upper bound. (You do want to conform with the PVP, right?)
documentation Check that haddocks can be created without problems (calling cabal haddock).
changelog Check if the changelog mentions (contains) the latest version.
package-sdist Check that all necessary stuff is contained in the source distribution by installing the packaged package.
compiler-versions Compile and run tests for several compiler versions (other than the default compiler on $PATH).
