ghc-mod master and GHC 7.10.1

gistfile1.txt

1. After installing GHC, checkout ghc-mod (https://github.com/kazu-yamamoto/ghc-mod) and build master using 7.10.1

2. Update your PATH to include the locaiton of the built 'ghc-mod' and 'ghci-mod' binaries

3. Update your emacs config to load up PATH to correctly locate ghc-mod. I needed to add some elisp to my emacs config

;; Some shell variable magic
(let ((path (shell-command-to-string ". ~/.zshrc; echo -n $PATH")))
  (setenv "PATH" path)
  (setq exec-path 
        (append
         (split-string-and-unquote path ":")
         exec-path)))

(when (memq window-system '(mac ns))
  (exec-path-from-shell-initialize))
  
4. Load the new elisp from the ghc-mod repo and remove any older ghc-mod packages out of emacs

(progn (cd "/path/to/ghc-mod/elisp/") (normal-top-level-add-subdirs-to-load-path))

(if (fboundp 'normal-top-level-add-subdirs-to-load-path)
    (let* ((my-lisp-dir "/path/to/ghc-mod/elisp/")
          (default-directory my-lisp-dir))
      (setq load-path (cons my-lisp-dir load-path))
          (normal-top-level-add-subdirs-to-load-path)))

5. Ensure that ghc-mod is loaded

That should be it :)
