Re: [Haskell-cafe] Haskell-mode 2.4
Emacs is completely frozen until I press C-g and then it goes back to normal (without loading the file). Here's the back trace: Debugger entered--Lisp error: (quit) accept-process-output(#process haskell) (and (not (re-search-forward comint-prompt-regexp nil t)) (accept-process-output proc)) So it seems to be waiting for the prompt but can't find it. If you look at the buffer containing the interactive process, is there a prompt there? If not, can you try and figure out why not? If yes, can you try and figure out why it is not recognized by the comint-prompt-regexp? I had the following in my .ghci to make GHCi's prompt less verbose: :set prompt Removing that solves the problem. Thanks! -- Johan ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Re: [Haskell-cafe] Haskell-mode 2.4
First of all, thanks. My Aqua Emacs (on OS X Leopard) hangs when I send a command like C-c C-l or C-c C-t to the interpreter (I can quit the command using C-g) . Starting the interpreter and using :l from inside it works fine. This is using GHC 6.8 (and I think I also tried 6.6.) What could be the problem? I also tried to eval this but it didn't make a difference: (setq inferior-haskell-find-project-root nil) It looks like this is a problem with 6.8.2 as haskell-mode-2.3 has the same problem? Seems like the commands being sent to the haskell process never reaches it. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

[Haskell-cafe] Haskell-mode 2.4
Here's for Xmas, version 2.4 of the Haskell-mode package. Haskell-mode is an Elisp package to support editing Haskell in Emacs. See the home page at http://www.iro.umontreal.ca/~monnier/elisp/ -- Stefan Changes since 2.3: * Update license to GPLv3. * New derived major mode for .hsc files. * Removed the C-c C-r binding to reload a file. You can still call inferior-haskell-reload-file (and/or bind it to your favorite key, including C-c C-r) or you can now use C-u C-c C-l. * C-c C-d looks up the symbol at point in the Haddock docs. * Haddock comments are highlighted with font-lock-doc-face if it exists. * Use `tex' rather than `latex' for haskell-literate. * inf-haskell.el tries to find the root of the module hierarchy to determine the root of a project (either by looking for a Cabal file or relying on the `module' declaration line). If all works well, this will make C-c C-l automatically switch to the root dir, so that dependencies in other directories are automatically found. If it doesn't, complain and/or set inferior-haskell-find-project-root to nil. * The new command haskell-hoogle helps you query Hoogle from Emacs. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
