Hi, running ghci (instead of hugs) in (GNU-) emacs is quite fun. But a few improvements could even increase the fun: a) adding arguments to the ghci was not well documented. So I appended the following (and a few more paths) to my .gnu-emacs: ;(add-hook 'haskell-mode-hook 'turn-on-haskell-hugs) (add-hook 'haskell-mode-hook 'turn-on-haskell-ghci) (setq haskell-ghci-program-args (append '("-fglasgow-exts") '("-fallow-overlapping-instances") '("-Wall") '("-package data") '("-i.:..") )) b) When an error occurs, the cursor jumps to the first error or warning. That's ok, but sometimes a warning is produced by an imported Module that has no errors and then this file is loaded into the buffer. Usually, I try to avoid all warnings, but I was not able to avoid: Warning: Module `I' is imported, but nothing from it is used (except perhaps to re-export instances visible in `I') Indeed I want to import only instances from `I'. Maybe the warning can be suppressed when I explicitely write "import I()" to indicate that I import nothing except instances. (I don't want to switch off that import warning completely.) c) Can someone supply emacs commands (and keys) to step through all the errors and warnings? Regards Christian
