Installing haskell-mode into Emacs on Ubuntu 12 -

-

i'm following these instructions install haskell-mode on ubuntu 12. when point of typing m-x customize-option ret pac emacs says: no match! customizable variables shown in picture below.

any idea going wrong?

enter image description here

go init.el file (~/.emacs.d/init.el) , place there:

(setq package-archives       '(("gnu"         . "http://elpa.gnu.org/packages/")         ("original"    . "http://tromey.com/elpa/")         ("org"         . "http://orgmode.org/elpa/")         ("marmalade"   . "http://marmalade-repo.org/packages/")         ("melpa" . "http://melpa.milkbox.net/packages/")))  (package-initialize)

and m-x package-refresh-contents , can install haskell-mode there. make sure emacs version >= 24 since package.el bundled higher version. if using older version, may have manually install package.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
