2020-10-28 08:13:17 <dminuoso> binary question, when I have a tree of Get primitives, is there a good rule of thumb where to isolate?
2020-10-28 08:14:47 → idhugo joins (~idhugo@users-1190.st.net.au.dk)

2020-10-28 08:29:57 <eedgit> Why are these named 'op' / 'e' - is it completely random or does it have some significance? (can't google 'cause its too short :( )
2020-10-28 08:29:57 <eedgit> https://dpaste.org/cht0
2020-10-28 08:30:31 <dminuoso> The 'e' is likely random
2020-10-28 08:30:39 <dminuoso> And 'op' is just to suggest this is likely to be used with some kind of "operator"
2020-10-28 08:30:45 <dminuoso> Think:
2020-10-28 08:30:52 <dminuoso> % foldr (+) 0 [1,2,3,4,5]
2020-10-28 08:30:52 <yahb> dminuoso: 15
2020-10-28 08:31:27 <eedgit> thank you! I thought that might be operator. Is there a big list of commonly used vars / built in ones
2020-10-28 08:31:36 <eedgit> To a novice it's like staring at a bowl of alphabet soup sometimes
2020-10-28 08:35:38 <merijn> eedgit: I don't think there is a list, some common ones would be f/g/h for functions, i/j/k for indices, any single letter for just "a value of some polymorphic type"
2020-10-28 08:36:10 <merijn> eedgit: oh, and of course the (x:xs) idiom (following from 1 item, multiple itemS you get 1 x, multiple xS)
2020-10-28 08:36:22 → kish joins (~oracle@unaffiliated/oracle)
2020-10-28 08:38:28 <merijn> eedgit: I might call the 'e' "acc" (for accumulator or something), but it's not really clear what a "better" name would be.
2020-10-28 08:39:56 <eedgit> `acc` is much better thanks
2020-10-28 08:41:11 → ensyde joins (~ensyde@99-185-235-117.lightspeed.chrlnc.sbcglobal.net)

2020-10-28 08:46:49 → FreeBirdLjj joins (~freebirdl@101.228.42.108)
2020-10-28 08:47:07 <dminuoso> eedgit: I tend to not like `acc` because it leads to a more imperative thinking.
2020-10-28 08:47:56 <dminuoso> https://wiki.haskell.org/wikiupload/3/3e/Right-fold-transformation.png
2020-10-28 08:48:28 <dminuoso> So if we foldr a list, then that second argument really is just what the empty list at the end gets replaced with.
2020-10-28 08:51:22 × FreeBirdLjj quits (~freebirdl@101.228.42.108) (Ping timeout: 265 seconds)

2020-10-28 08:53:51 × britva quits (~britva@31-10-157-156.cgn.dynamic.upc.ch) (Quit: This computer has gone to sleep)
2020-10-28 08:54:32 <tomsmeding> "imperative thinking" certainly fits the time of year, does it not?
2020-10-28 08:55:06 <merijn> Nothing wrong with imperative Haskell :)
2020-10-28 08:55:10 × christo quits (~chris@81.96.113.213) (Remote host closed the connection)

2020-10-28 08:59:38 <Rembane> As long as you don't think imperitavel... yeah... you can program using the style. *nods sagely*
2020-10-28 09:00:02 × m4v1 quits (~m4v@185.244.214.217) ()

2020-10-28 09:01:08 <eedgit> dminuoso that's hurting my head a bit. Is the distinction you're making that it's 'folded' into the end, rather than accumulated in a new variable?
2020-10-28 09:02:42 <tomsmeding> eedgit: 'foldr op e l' really just replaces the (:) in l with op, and the [] in l with e
2020-10-28 09:03:14 × GyroW quits (~GyroW@unaffiliated/gyrow) (Quit: Someone ate my pie)
2020-10-28 09:03:26 <tomsmeding> foldr op e (1 : (2 : (3 : [])) = 1 `op` (2 `op` (3 `op` e))

2020-10-28 09:03:30 → GyroW joins (~GyroW@unaffiliated/gyrow)
2020-10-28 09:03:44 <tomsmeding> hence 'e' for "empty list"
2020-10-28 09:04:28 <tomsmeding> oh that's what the picture says, lol
2020-10-28 09:04:46 <eedgit> ahh ok, think I've got it (*whiteboarding intensifies*)
