\begin{hcarentry}[updated]{ghc-mod --- Happy Haskell Programming}
\report{Kazu Yamamoto}%11/14
\status{open source, actively developed}
\makeheader

For a long time, Kazu Yamamoto was the only active developer of ghc-mod, now two
new developers have joined:

Alejandro Serrano merged the results of his Google Summer of Code project. He
implemented case splitting and sophisticated typed hole handling.  Daniel Gröber
brushed up the internal code and introduced the GhcModT monad now used
throughout the exported API. As a result the API of \texttt{ghc-mod} drastically
changed with version 5.0.0.

\texttt{ghc-modi} used to suffer from various consistency related issues
triggered by changes in the environment, for instance: changing file names of
modules, adding dependencies to the cabal file and installing new libraries.
\texttt{ghc-modi} v5.1.1 or later handles changes in the environment by
restarting the GHC session when this is detected.

Kazu stepped down as release manager and Daniel took over.
