I expect there to be quite a lot of shared code. It's not solely an indenter; the same interface and capabilities will be used for a debugger, refactoring, and type signature info. Haskell-mode should still work without it, to about the same degree as today, but actually doing so would be a *major* degradation compared to the state of the art once I'm done with it. In any case, I expect the actual installation to be via cabal-install. -- Svein Ove Aas ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Why should it? Look at all the effort that the Haskell community went through to _unbundle_ libraries from GHC, and now Emacs is bundling more and more with it, which means it's harder to use a newer version of a package than the bundled one. -- Ivan Lazar Miljenovic ivan.miljeno...@gmail.com IvanMiljenovic.wordpress.com ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

We can cycle between these, but it's better to minimize them. - I want the parser to be as accurate as possible. This essentially means reimplementing haskell-src-exts, unless I *use* haskell-src-exts. - In many cases, the legal indentations depend on the types of the expressions involved. This can be figured out, but requires part of the code to be running in GHC *anyway*. - Elisp is a lousy language compared to haskell, and I don't really care about getting haskell-mode into the emacs distribution. It makes more sense to bundle it with GHC, if it has to be bundled. - Most of haskell-mode will work without this helper program, including the three other indentation modes. -- Svein Ove Aas ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Hey Svein, Any chance of including haskell-align-imports somehow in the next release? http://gist.github.com/453933 (Re-license it for inclusion however you wish, I don't care.)

[Haskell-cafe] ANN: Haskell-mode 2.8.0
I'm happy to (finally) announce haskell-mode 2.8.0, which can be found at http://projects.haskell.org/haskellmode-emacs/ This is a feature release. I'll let the changelog speak for itself: * Minimal indentation support for arrow syntax * Autolaunch haskell-mode for files starting with #!/usr/bin/runghc and similar * Added minimal major mode for parsing GHC core files, courtesy of Johan Tibell. There is a corresponding Haskell menu entry. * Allow configuration of where-clause indentation; M-x customize-group haskell-indentation. You can expect a 2.8.1 or even 2.8.2 in the near future, as I attempt to empty the bug list, but I thought I might as well get the new features out there quickly. There's bound to be new bugs associated with them. -- Svein Ove Aas ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
