Hello, I am pleased to announce the first release of Scion. Scion [1] is a Haskell library that aims to implement those parts of a Haskell IDE which are independent of a particular front-end. Scion is based on the GHC API and Cabal. It provides both a Haskell API and a server for non-Haskell clients such as Emacs and Vim. Scion is bundled with two front-ends, Emacs and Vim, and is used by the Haskell Eclipse plugin EclipseFP. Work on Yi support is underway. Scion's current features include: - Opening (that is, typechecking) a component of a Cabal project or a single file [Emacs, Vim]. Error messages are highlighted in the source [Emacs]. - Saving a file automatically typechecks the file [Emacs, Vim]. This feature can be turned off. - Look up the type of any identifier (even local variables) [Emacs, Vim]. Requires that the file typechecks. - Jump to definition of an identifier defined in the current project [Emacs]. For more details on the provided features and instructions of how to set up a particular front-end see the README [2]. Patches are always welcome. The main source repository is hosted on Github [3]. If you find a problem please file a bug [4] and/or join the developer's mailing list [5].
