2021-03-03 12:18:25 <romesrf> i'm just learning haskell, so Foldable and Monoid is something i don't know yet :)
2021-03-03 12:18:26 <cheater> well not the function fold
2021-03-03 12:18:30 <cheater> you want /a/ fold

2021-03-03 12:18:39 <cheater> go read up on the differences between foldr and foldl
2021-03-03 12:18:45 <cheater> there's that wiki page
2021-03-03 12:18:52 <romesrf> Okay, I will

2021-03-03 12:19:32 <tdammers> ((although at this level, it boils down to "use foldl', not foldl, because Trust Me™))
2021-03-03 12:20:06 <cheater> tdammers: it's the same wiki page
2021-03-03 12:20:06 <romesrf> > trust me™ahahahahahaha
2021-03-03 12:20:08 <lambdabot> error: Variable not in scope: trust :: t1 -> t0error:
2021-03-03 12:20:08 <lambdabot> • Variable not in scope: me
2021-03-03 12:20:08 <lambdabot> • Perhaps you meant one of these:
2021-03-03 12:20:23 <romesrf> how do i tag people in the channel? (using weechat - also new to it)
2021-03-03 12:20:38 <tdammers> you just write their nick without further decorations
2021-03-03 12:20:44 <tdammers> like so: romesrf
2021-03-03 12:20:49 <romesrf> beatiful +1
2021-03-03 12:20:58 <boxscape> romesrf if you type the beginning of someone's name weechat will let you complete it by hitting `tab` as well
2021-03-03 12:21:06 <tdammers> a common format is "nick: message" though
2021-03-03 12:21:10 <romesrf> really nice!
2021-03-03 12:21:22 <tdammers> and yeah, weechat completion does that automatically at the beginning of a message

2021-03-03 12:22:08 <mananamenos> I have Main.hs which import Foo.hs. When running `cabal new-build` I get a warning: These modules are needed for compilation but not listed in your .cabal file's other-modules: Foo. Why? To remove this warning I have to add Foo to other-modules in .cabal file.
2021-03-03 12:22:45 × __minoru__shirae quits (~shiraeesh@109.166.56.89) (Ping timeout: 264 seconds)
2021-03-03 12:22:48 <merijn> mananamenos: What's the question?

2021-03-03 12:24:31 <mananamenos> merijn, I thought that having `hs-source-dirs: src` and having all the module in src dir is enough. Or do I have to each and every module name now in other-modules so I dont see that warning.
