{\tt ghc-mod} is a package to enrich Haskell programming on editors including Emacs, Vim and Sublime. The {\tt ghc-mod} package on Hackage includes the {\tt ghc-mod} command, new {\tt ghc-modi} command and Emacs front-end.
|
|
|
|
Emacs front-end provides the following features:
|
|
|
|
\begin{description}
|
|
\item[Completion] You can complete a name of keyword, module, class, function, types, language extensions, etc.
|
|
|
|
\item[Code template] You can insert a code template according to the position of the cursor. For instance, {\tt import Foo (bar)} is inserted if {\tt bar} is missing.
|
|
|
|
\item[Syntax check] Code lines with error messages are automatically highlighted. You can display the error message of the current line in another window. {\tt hlint} %\cref{hlint}
|
|
can be used instead of GHC to check Haskell syntax.
|
|
|
|
\item[Document browsing] You can browse the module document of the current line either locally or on Hackage.
|
|
|
|
\item[Expression type] You can display the type/information of the expression on the cursor.
|
|
\end{description}
|
|
|
|
\noindent
|
|
There are two Vim plugins:
|
|
\begin{itemize}
|
|
\item ghcmod-vim
|
|
\item syntastic
|
|
\end{itemize}
|
|
|
|
\noindent
|
|
Here are new features:
|
|
\begin{itemize}
|
|
\item New {\tt ghc-modi} command provides a persistent session to make response time drastically faster. So, now you can use Emacs front-end without stress.
|
|
\item Emacs front-end provides a way to solve the import hell.
|
|
\item GHC 7.8 is supported.
|
|
\end{itemize}
