Perhaps the best answer is for someone to make editline bindings for Haskell?
I don't *think* libedit provides the completion functionality that we use in GHC, but I could be wrong.
The only way to know for sure is to try it out! Attached is a proof-of-concept patch which adds the --with-libedit flag to the readline package's autoconf scripts. * PROOF OF CONCEPT: add --with-libedit flag to allow building a minimal version of the library against libedit. M ./HsReadline_cbits.c +2 M ./System/Console/Readline.hsc -1 +50 M ./aclocal.m4 +6 M ./configure.ac -4 +10 With this patch (and a small, unrelated hack to statically link gmp) I was able to build a version of ghc which only depends on the dynamic libraries installed on OS X 10.4 by default: $ otool -L ghc-6.9.20071221 ghc-6.9.20071221: /usr/lib/libedit.2.dylib (compatibility version 2.0.0, current version 2.0.0) /usr/lib/libncurses.5.4.dylib (compatibility version 5.4.0, current version 5.4.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.3.9) I played around with completion of filenames, modules, identifiers and flags in ghci, and it all seems to be working fine.
