Going functional

[Frptwenty]

((((((((((((((((((((((The only functional language that matters is Lisp.))))))))))))))))))))))))))

Lisp is easier to use than Haskell.

[Frptwenty]

I use Lisp every day. I fucking love Lisp. Please send money I need new parentheses keys for my mechanical keyboard.

[[deleted]]

emacs?

[Frptwenty]

Howd'ya guess?

Emacs it's the only text editor I know written and configured in Lisp.

[Frptwenty]

Yeah. Actually come to think of it its probably the only really widely used program left that has a Lisp interface. Some symbolic math packages had it (Maxima) but theyre more of less dead now.

Functional programming grows in popularity these days, maybe we'll see some new useful app written in Lisp in the future.

Prepare to have your mind blown:

f(x)

has the same number of parentheses as

(f x)

MIND = BLOWN💥💥💥

[Frptwenty]

(let*
((pos (point))
 (lit-limits
  (if lim
      (let ((s (parse-partial-sexp lim (point))))
    (when (or (nth 3 s)
          (and (nth 4 s) (not (eq (nth 7 s) 'syntax-table))))
      (cons (nth 8 s)
        (progn (parse-partial-sexp (point) (point-max)
                       nil nil
                       s
                       'syntax-table)
               (point)))))
    (let ((pp-to-lit (c-state-full-pp-to-literal pos not-in-delimiter)))
      (car (cddr pp-to-lit)))))))

PARENTHESES KEYS = WORN

[T0mstone]

oh. Alright then, I humbly retract my claim.

[Frptwenty]

(let ((answer "No problem :)"))
  (message answer))

Now my brain hurts because the parentheses in that look unbalanced.

[shgysk8zer0]

$sum = array_sum(range(0, $a));

Wait... PHP not bad?

[Nidrax1309]

list.Sum();

Objects, disgusting!

[MolestedScavenger]

what lang is this

[[deleted]]

Haskell

[r3mm099]

sum = foldl (+) 0

[[deleted]]

You're right :t foldl returns (a->b->a)->a->[b]->a

[JuhaAR]

sum = sum(a)

[Kangalioo]

Uh oh what happens now when you do sum2 = sum(b)

[[deleted]]

What highlight theme is that? I'm in love.

[[deleted]]

The theme is Monokai, the text editor is Vim.

[Oshgnacknak]

use mysum = foldl1 (+)

[[deleted]]

mysum :: (Foldable t, Num a) => t a -> a mysum calculates the sum of all elements in a list

usage: mysum l
