there's no denying it lol

any /prog/ regulars here? look at this faggot.
/prog/ is shit.

sage

That's it, I'm outta here.

This is a Ruby Ferret (read W(P)GtR) also I invented that meme.

>>2-4
Funny, I would have never assumed that such blatant attempts at posing as different people don't happen on /prog/.

Banping a shitty thread.

>>6
Learn English and then try again to make a comprehensible sentence.
By the way, I'm >>2 and not anyone else in this thread.

>>8
By the way. I'm >>2 and everyone else in this thread, and I have trolled you exponentially.
Fixed.

>>9
No.
That trolled exponentially bullshit is pure BS coming from redditfags.
GTFO.

>>10
''GTFO`` is /b/tard talk.

>>11
BS. GTFO's been around more than /b/ or you.
Next thing you're going to tell me lol came from /b/.

>>12
I regret to inform you that you were actually just trolled a short while ago, that you have lost everything, and that you should have a nice day.

>>13
no, >>1 is not a troll.
Trolls have dignity, I've been long enough on usenet son, believe me.

Question:
In EMACS, when I want to load a function for the whole session, what hook do I use? 'emacs-startup-hook runs the function, but the effect ceases when I open a new buffer.

>>15
Read SICP.

>>15
You just define it....

>>15
defun foo()
(car (other cdr))

>>15
Use the new-buffer-hook, which doesn't exist yet.

>>19
import from ______future______

I am sorry to pollute your nice haskell ferret thread, but I just started reading YAHT, and I have a question about Exercise 3.4:

Use the functions mentioned in this section (you will need two of them) to compute the number of lower-case letters in a string. For instance, on “aBCde” it should return 3.

Is there a way to write it with foldl/r? I am familiar with perl, and foldl looks a lot like reduce from List::Util, but I tried many combinations and all of them failed (foldl (+1) 0 filter (Char.isLower) "aBCde" foldl (1+) 0 filter (Char.isLower) "aBCde", ie ignoring values and only using item count, in perl that would be reduce{$a+1} 0, @list)

Also, will it be explained in yaht why length(filter (Char.isLower) "aBCde") works, but length filter (Char.isLower) "aBCde" does not?

Sure: foldr (\ c s -> if Char.isLower c then s + 1 else s) 0 "aBCde"
Also, will it be explained in yaht why length(filter (Char.isLower) "aBCde") works, but length filter (Char.isLower) "aBCde" does not?
Write Lisp until you are more sure of the precedence and such: (length (filter Char.isLower "aBCde"))

Your failed example calls length with three parameters.

Oh, and if you wanted a silly solution for counting lower-case letters:
(foldr (const (+1)) 0 (filter Char.isLower "aBCde"))

fucking faggot I fucking fucking hate you.

NOOOOOOOOOOOOOOOOOOOOoooooooooooooooooooooooooooooooooooo

Say hi to Haskell in Heaven.

_________"""FIOC"""_________

Thanks

*Main> :t foldl
foldl :: forall a b. (a -> b -> a) -> a -> [b] -> a
*Main> :t foldr
foldr :: forall a b. (a -> b -> b) -> b -> [a] -> b

what does forall mean? wouldn't (a -> b -> a) -> a -> [b] -> a be enough?

Oh I'm sorry, i just accidentally ran interpreter with some unnecessary flags

>>31
oh shi-

Forall is some legacy shit left over from some old version of Haskell where it wasn't inferred automatically.

No one except SPJ knows what it does.
