I am trying to setup emacs for haskell. I downloaded haskell-mode with el-get and some parts are working (like indentation, starting ghci, etc.) but I can't get the tags-generation working.
Hasktags is installed, and
(load "~/.emacs.d/el-get/haskell-mode/haskell-site-file") is added to my init-file.
Does hasktags need to be in a certain directory? (I added the directory to PATH, no success.)
The haskell-process-generate-tags function is not available with M-x. When I add (load "~/.emacs.d/el-get/haskell-mode/haskell-process.el") manually to the init-file the function is available but no TAGS file is generated.
(PS: I am using emacs 24.1 with linux)
hasktags should be in PATH, but are you sure that PATH in Emacs is the same as PATH in shell? I just tried, and haskell-process-generate-tags worked for me without problem. Try to setup PATH from Emacs with:
(setenv "PATH" (concat (getenv "PATH") ":directory_with_hasktags"))
You can also bind C-x C-s to haskell-mode-save-buffer as described in examples/init.el - in this case, you can set haskell-tags-on-save variable to t, and hasktags will be called on every save of you haskell files.
