2026-02-25 18:35:27 <__monty__> Indentation in do-notation always trips me up. let ... in ... has no qualms with the definitions being less indented than the let.
2026-02-25 18:35:31 <ski> (iow, breaking line after `let', then you can indent the followin lines a little bit less)
2026-02-25 18:36:02 <Milan_Vanca> Yeah thy guyz now I get it. :)
2026-02-25 18:36:06 <Milan_Vanca> TY
2026-02-25 18:36:14 <ski> yea .. the block starts at the first (non-comment) token *after* the layout-introducing keyword (here `let')
2026-02-25 18:36:34 <ski> (in Milan_Vanca's case, the block starts at `result')
2026-02-25 18:37:20 <ski> (same rule holds for `of', and for `do', and `where')
2026-02-25 18:38:29 <haskellbridge> <ijouw> let x = y in and let x = y have same rules reguarding where x may be. Everything y must be indented more than x.
2026-02-25 18:38:39 <probie> If you don't want to indent, you can always just use braces
2026-02-25 18:38:40 × tromp quits (~textual@2001:1c00:3487:1b00:7955:9591:6018:7ef9) (Quit: My iMac has gone to sleep. ZZZzzz…)
2026-02-25 18:39:05 <ski> Milan_Vanca : btw, if you wanted to, you could factor out some common code from the two branches
2026-02-25 18:39:09 wickedja` joins (~user@2605:8d80:5430:818:b927:d532:959:409c)
2026-02-25 18:39:30 <__monty__> But braces require semicolons, eww.
2026-02-25 18:40:58 <probie> Only if you want more than one thing :p
2026-02-25 18:41:03 × wickedjargon quits (~user@208.98.208.115) (Ping timeout: 246 seconds)
2026-02-25 18:41:39 <ski> let (status,result) = case eitherDecode body of
2026-02-25 18:41:59 <Milan_Vanca> I don't think same rules apply for where I can have where\n..something or where\n..................something
2026-02-25 18:42:02 <ski> Left e -> (status400,PL.pack e)
2026-02-25 18:42:15 <ski> Right c -> (status200,encode (increment c))
2026-02-25 18:42:28 <ski> return (responseLBS status [(hContentType,hvAplicationJSON)] result)
2026-02-25 18:43:08 <Milan_Vanca> ski: Nicer solution.. so tuple is ok ni this case?
2026-02-25 18:43:22 <ski> Milan_Vanca : yes, it's same rule. `where'-block also starts at whatever column `something' is at, regardless of which column `where' is at
2026-02-25 18:43:41 <ski> you can always match on tuples, in `let' and `where' (and toplevel)
2026-02-25 18:44:13 × rncwnd quits (~quassel@2a01:4f8:221:27c6::1) (Quit: Later)

2026-02-25 18:45:11 <ski> (and on other data constructors. however, a value of tuple type can never fail to match a tuple pattern, but for data types with multiple data constructors, you can get match failure, so it's good to only match on those, in `let'/`where'/toplevel sparingly, when you're sure that they won't actually fail ..)

2026-02-25 18:46:48 <ski> hah, ijouw :)
2026-02-25 18:47:05 <haskellbridge> <ijouw> i did not typecheck it
2026-02-25 18:47:43 <Milan_Vanca> ijouw do you really find this more readable?
2026-02-25 18:47:44 <probie> > (\xs -> let y:ys = xs in if null xs then Nothing else Just (y, ys)) []
2026-02-25 18:47:45 <lambdabot> Nothing
