2020-09-30 03:45:19 <sim590> How can I download a package with cabal globally, build it globally and then build my project that uses the same library without building it again?
2020-09-30 03:45:45 <sim590> and I mean all of that before switching to the directory containing my project.
2020-09-30 03:47:15 <sim590> I don't want to download and build the library more than once.
2020-09-30 03:47:44 → Guest_91 joins (48855e8f@cpe-72-133-94-143.sw.res.rr.com)
2020-09-30 03:48:38 × ericsagnes quits (~ericsagne@2405:6580:0:5100:4d11:5c80:3101:9ff9) (Ping timeout: 244 seconds)
2020-09-30 03:48:42 <Axman6> I think that happens with the new style builds, identical builds should be shared between projects AFAIUI
2020-09-30 03:48:59 × darjeeling_ quits (~darjeelin@112.16.171.8) (Ping timeout: 260 seconds)
2020-09-30 03:50:14 <Guest_91> Hello after you install Haskell on OS X how do you start running it
2020-09-30 03:50:29 <Axman6> what do you want to start? ghci?
2020-09-30 03:50:35 <sim590> OK. I'm building a docker image. I'm trying this: https://paste.debian.net/1165214/. It's essentially copying my cabal file and building the project libraries there.
2020-09-30 03:50:37 × toorevitimirp quits (~tooreviti@117.182.182.201) (Ping timeout: 244 seconds)
2020-09-30 03:50:43 <Axman6> most of what is installed is a compiler
2020-09-30 03:51:28 <sim590> Shouldn't this make it so that if I run a build of the same project inside the resuting image, I should be able to build my project without downloading/building all of the dependencies?
2020-09-30 03:51:42 → iqubic joins (~user@2601:602:9500:4870:d13c:5aea:b558:d2ed)
2020-09-30 03:52:19 <Guest_91> yes ghci
2020-09-30 03:52:28 <Axman6> run ghci in the termina;
2020-09-30 03:52:31 <Axman6> l*
2020-09-30 03:53:05 <Guest_91> I tried that and it gives command not found
2020-09-30 03:53:29 <Axman6> open a new terminal and try again, your PATH won't be updated in an already open terminal
2020-09-30 03:53:40 <Axman6> how did you install things?
2020-09-30 03:55:14 <sim590> Shouldn't this: https://i.imgur.com/GtUn39G.png work? One of my dependencies is Colog.
2020-09-30 03:55:52 <Guest_91> thanks! it was the opening of new term window
2020-09-30 03:56:06 <Axman6> have you loaded the Colog module? :m +Colog.Monad
2020-09-30 03:56:43 <Axman6> :l(oad) is for local modules, :m(odule) loads modules visible to GHC
2020-09-30 03:57:05 <Axman6> (that's a really poor explanantion, but basically any library would be loaded with :m)
2020-09-30 03:57:26 → kreative joins (~kreative@185.163.110.116)
2020-09-30 03:58:35 × inerkick quits (~rohit@117.230.9.17) (Quit: Leaving)
2020-09-30 04:00:01 × Guest_91 quits (48855e8f@cpe-72-133-94-143.sw.res.rr.com) (Quit: Ping timeout (120 seconds))
2020-09-30 04:00:28 <sim590> it doesn't work: https://i.imgur.com/BkeFbYY.png
2020-09-30 04:00:38 <sim590> Normally, it would say to load the package first or something, no?
2020-09-30 04:00:42 <sim590> Anyway, it doesn't load.
2020-09-30 04:01:24 → ericsagnes joins (~ericsagne@2405:6580:0:5100:c862:81df:d6b3:8407)
2020-09-30 04:02:07 × ChaiTRex quits (~ChaiTRex@gateway/tor-sasl/chaitrex) (Remote host closed the connection)
2020-09-30 04:02:13 → day_ joins (~Unknown@unaffiliated/day)
2020-09-30 04:02:43 → ChaiTRex joins (~ChaiTRex@gateway/tor-sasl/chaitrex)
2020-09-30 04:05:05 × day quits (~Unknown@unaffiliated/day) (Ping timeout: 240 seconds)
2020-09-30 04:05:05 day_ is now known as day
2020-09-30 04:05:10 <sim590> That's the output when I'm building the docker image: https://i.imgur.com/74FKwjQ.png
2020-09-30 04:05:50 <Axman6> without knowing more about what you've done there's no way to know how to help.
2020-09-30 04:06:08 <sim590> What I did is in the docker image.
2020-09-30 04:07:42 × polyphem quits (~p0lyph3m@2a02:810d:640:776c:76d7:55f6:f85b:c889) (Ping timeout: 260 seconds)
2020-09-30 04:09:05 <sim590> I've published my latest attempt at docker.io/sim590/hart
2020-09-30 04:09:51 <Axman6> "Ahoy, it looks like you are in uncharted waters"
2020-09-30 04:10:33 <sim590> Yeah the URL is https://hub.docker.com/repository/docker/sim590/hart, but the image is named sim590/hart. Tag can be :latest, so sim590/hart:latest.
2020-09-30 04:11:13 × merijn quits (~merijn@83-160-49-249.ip.xs4all.nl) (Ping timeout: 260 seconds)
2020-09-30 04:11:15 <sim590> You could inspect it with `docker run -it sim590/hart:latest bash` if you could then tell me what's wrong.
2020-09-30 04:11:25 × beka quits (~beka@gothdyke.mom) (Ping timeout: 240 seconds)
2020-09-30 04:12:25 × mmaruseacph2 quits (~mihai@198.199.100.72) (Ping timeout: 240 seconds)
2020-09-30 04:12:37 → filwisher joins (~filwisher@cpc76738-dals23-2-0-cust186.20-2.cable.virginm.net)
2020-09-30 04:12:40 → mmaruseacph2 joins (~mihai@198.199.100.72)
2020-09-30 04:12:42 <sim590> I do have 891M of stuff inside /root/.cabal.
2020-09-30 04:13:18 <Axman6> I'm not going to run untrusted docer images on my machine, sorry. what does running a shell in it and running ghc-pkg list show?
2020-09-30 04:14:34 → beka joins (~beka@gothdyke.mom)
2020-09-30 04:15:09 <sim590> When looking inside ~/.cabal for co-log with docker run -it sim590/hart:latest find /root/.cabal -name \*co-log\*, I get this: https://paste.debian.net/1165215/
2020-09-30 04:15:52 <sim590> ghc-pkg list shows: https://paste.debian.net/1165216/.
2020-09-30 04:15:55 <Axman6> and if you run ghci -package co-log?
2020-09-30 04:17:18 × filwisher quits (~filwisher@cpc76738-dals23-2-0-cust186.20-2.cable.virginm.net) (Ping timeout: 272 seconds)
2020-09-30 04:17:25 <Axman6> and what happens if instead of using ghci directly, you use cabal new-repl?
2020-09-30 04:17:44 <Axman6> (I think that's a thing, I haven't used cabal directly for a long time)
2020-09-30 04:18:02 <sim590> ghci -package co-log: https://paste.debian.net/1165217/
2020-09-30 04:18:06 × dolio quits (~dolio@haskell/developer/dolio) (Quit: ZNC 1.8.1 - https://znc.in)
2020-09-30 04:19:16 <sim590> So the last command I did, I did move from /opt/hart to do this because I wanted to move from it to see if package was globally there.
2020-09-30 04:20:12 <sim590> now after doing `cabal new-repl̀ from inside the /opt/hart directory, it's building stuff like https://paste.debian.net/1165218/
2020-09-30 04:20:28 × wroathe quits (~wroathe@c-68-54-25-135.hsd1.mn.comcast.net) (Ping timeout: 272 seconds)
2020-09-30 04:20:44 <sim590> But I thought it would have built already.
2020-09-30 04:21:31 <sim590> But it won't be able to build `hart` since the code is not inside the image.
2020-09-30 04:21:43 <Axman6> how are docker so bad a things. can;t even get the docker hub page to load again
2020-09-30 04:21:44 <sim590> I just pushed my cabal file.
2020-09-30 04:22:03 <sim590> The URL I gave you?
2020-09-30 04:22:16 <Axman6> can you paste your docker file in dpaste? I can't load docker hub any more
2020-09-30 04:22:35 × Jonno_FTW quits (~come@api.carswap.me) (Ping timeout: 260 seconds)
2020-09-30 04:23:18 → Jonno_FTW joins (~come@api.carswap.me)
2020-09-30 04:23:30 <sim590> ␒The docker file is:https://paste.debian.net/1165214/

2020-09-30 04:30:08 <sim590> OK. I just tried to do a new-install --only-dependencies after doing a new-build --only-dependencies and I think that it is wokring. Not sure, but I can now load the package inside ghci with -package co-log
2020-09-30 04:30:10 → filwisher joins (~filwisher@cpc76738-dals23-2-0-cust186.20-2.cable.virginm.net)
2020-09-30 04:30:50 <sim590> I did new-install --lib --only-dependencies -j4 actually

2020-09-30 04:32:36 → Orbstheorem joins (~roosember@hellendaal.orbstheorem.ch)
2020-09-30 04:32:44 <sim590> I'm trying to rebuild the image now https://paste.debian.net/1165220/ and see if it fixes it.
2020-09-30 04:34:16 <bobajett> how can I write the function p where p [0,0,1,2,0,0,3,0] == [[1,2], [3]] ? (Noobie question)
2020-09-30 04:34:45 <glguy> > let f [0,0,1,2,0,0,3,0] = [[1,2], [3]] in f [0,0,1,2,0,0,3,0]
2020-09-30 04:34:48 <lambdabot> [[1,2],[3]]
