Hello folks,

More that two years after the 0.1.0 release, I would like to attract people's attention to recent developments on the Yi editor. This preview release is an attempt to gather more users, testers and hopefully contributors for an upcoming "stable" release.

Yi is a text editor written and extensible in Haskell. The goal of Yi is to provide a flexible, powerful and correct editor core dynamically scriptable in Haskell.

* Yi is an haskell interpreter. Much like emacs is a Lisp interpreter, Yi is an haskell interpreter. This is implemented by binding to the GHC API. This permits hacking of the editor behaviour at runtime. Tools and goodies written in haskell are also readily available from the editor.

* Frontends. Yi can use either gtk2hs or vty as frontends, so users can choose their favourite interface.

* "Emulation modes". The primary emulation modes for Yi are vi and emacs. Keybindings for vim, mg and nano and other are also provided. Other editor interfaces can be written by the user to extend Yi.

Patches, comments, criticism welcome... as always!

I'm trying to install yi but I get the following error: bas@bassbox ~/development/haskell/yi $ runhaskell Setup.hs configure --user --prefix=$HOME Configuring yi-0.2... configure: Dependency ghc>=6.6: using ghc-6.6 configure: Dependency base-any: using base-2.0 configure: Dependency mtl-any: using mtl-1.0 configure: Dependency regex-posix-any: using regex-posix-0.71 configure: Using install prefix: /home/bas configure: Binaries installed in: /home/bas/bin configure: Libraries installed in: /home/bas/lib/yi-0.2/ghc-6.6 configure: Private binaries installed in: /home/bas/libexec configure: Data files installed in: /home/bas/share/yi-0.2 configure: Using compiler: /usr/bin/ghc configure: Compiler flavor: GHC configure: Compiler version: 6.6 configure: Using package tool: /usr/bin/ghc-pkg configure: Using ar found on system at: /usr/bin/ar configure: Using haddock found on system at: /usr/bin/haddock configure: No pfesetup found configure: Using ranlib found on system at: /usr/bin/ranlib configure: Using runghc found on system at: /usr/bin/runghc configure: Using runhugs found on system at: /usr/bin/runhugs configure: Using happy: /usr/bin/happy configure: Using alex: /usr/bin/alex configure: Using hsc2hs: /usr/bin/hsc2hs configure: Using c2hs: /usr/bin/c2hs configure: Using cpphs: /usr/bin/cpphs configure: No greencard found bas@bassbox ~/development/haskell/yi $ runhaskell Setup.hs build *** Exception: failed to extract ghc path from command line I thought it had something to do with an older version of Cabal because the README lists Cabal 1.1.8 as a dependency. So I build a fresh Cabal from darcs and installed it in my user database: bas@bassbox ~/development/haskell/yi $ ghc-pkg -L /usr/lib/ghc-6.6/package.conf: (Cabal-1.1.6), Cabal-1.1.6.1, FilePath-0.11, GLUT-2.0, HUnit-1.1, HaXml-1.13.2, OpenGL-2.1, QuickCheck-1.0, X11-1.2, X11-extras-0.0, arrows-0.2, base-2.0, cpphs-1.2, fgl-5.3, (ghc-6.6), haskell-src-1.0, haskell98-1.0, hsql-1.7, hsql-mysql-1.7, html-1.0, mtl-1.0, network-2.0, parsec-2.0, readline-1.0, regex-base-0.71, regex-compat-0.71, regex-posix-0.71, rts-1.0, stm-2.0, template-haskell-2.0, time-1.0, unix-1.0, xhtml-2006.9.13 /home/bas/.ghc/i386-linux-6.6/package.conf: Cabal-1.1.7, DeepArrow-0.0, HAppS-0.8.8, HList-0.1, SDL-0.4.0, SDL-image-0.4.0, WashNGo-2.10, binary-0.2, haskelldb-0.10, haskelldb-hsql-0.10, haskelldb-hsql-mysql-0.10 but the error remains...
