2016-05-28 01:11:05 +0200 <djbeau> dgpratt: yep, that's what I do (I have to run either 'nix-env --install' or 'nix-env --upgrade --always' along with '--attr nixos.hsEnv')
2016-03-12 01:48:00 +0100 <mgsloan> I never was too good at cabal sandboxes, always just used hsenv in the pre stack days
2015-11-01 19:46:51 +0100 <robtaylor> looking for something liek hsenv/hsvm (to allow simple usage of multiple ghcs user level), but not bitrotten. Any ideas?
2015-10-07 20:58:38 +0200 <dmj`> Zemyla: maybe, cabal exec was meant to be like the old 'hsenv', I think it starts a new shell where the package database is set to that of the sandbox
2015-07-15 14:50:31 +0200 <shoggoth> I'm getting a segfault from hsenv; http://lpaste.net/136659; can anyone suggest why I'd be getting this?
2015-07-15 14:48:55 +0200 <lpaste_> shoggoth pasted “hsenv segfault” at http://lpaste.net/136659
2015-07-15 14:30:05 +0200 <shoggoth> when I run hsenv —ghc=7.10.1 (or any other version) I get a segmentation fault… I'm running linux mint and the apt-get'd version of ghc is 7.6.3; can anyone give me an idea of how to fix this?

2015-06-22 21:17:50 +0200 <geekosaur> (note that this will comprehensively fail if you're e.g. trying to install yesod onto a system with the Platform installed; about the only fix I've found there is start from Stackage, which is yesod's idea of a "Platform", and worst case have a separate minimal ghc for it (possibly via hsenv) :/
2015-06-01 02:37:06 +0200 <geekosaur> pharaun, hsenv may well be what you want
2015-06-01 02:36:21 +0200 <pharaun> geekosaur: hm, i did hear of hsenv, but eh, i mostly wanted 2 ghc, one userland ghc, and one system ghc, so i do't have to worry about system updates breaking my sandboxes, and correspeondingly i don't need to worry about being held back by what is installed in system.
2015-06-01 02:34:26 +0200 <geekosaur> another alternative is hsenv but then you have to switch environments between sandboxes
2015-05-31 17:05:35 +0200 <geekosaur> you could use hsenv to install a private minimal ghc
2015-04-24 16:02:25 +0200 <geekosaur> saml: sandboxes are partial. hsenv is more like virtualenv... but rarely necessary
2015-04-24 03:40:43 +0200 <saml_> do you recommend hsenv?
2015-04-08 15:36:56 +0200 <merijn> RaceCondition: I don't even use hsenv or anything fancy like that
2015-04-08 15:31:36 +0200 <srhb> RaceCondition: Probably some kind of hsenv usage.
2015-03-31 01:44:19 +0200 <mgsloan> For readers of the archive: I figured out how to fix my hsenv. "rm .hsenv/ghc_pkg_db/package.cache; cp .hsenv/ghc/lib/ghc-7.10.1/package.conf.d/package.cache .hsenv/ghc_pkg_db/package.cache"
2015-03-31 01:31:46 +0200 <mgsloan> Yeah, seems like people would notice hsenv not working quite rapidly, so must be some local issue..
2015-03-31 01:28:31 +0200 <mgsloan> Hrmm hsenv doesn't seem to work with GHC 7.10. Has anyone tried that? https://gist.github.com/mgsloan/6eb77382be523ad04137
2015-03-30 16:18:21 +0200 <merijn> I've mostly found hsenv a bit cumbersome without much value, but YMMV
2015-03-30 16:17:59 +0200 <geekosaur> hsenv might be slightly easier to script for that workflow though
2015-03-13 23:48:16 +0100 <levi> sm: There's a tool called hsenv that's designed for working with multiple versions of ghc; might work a bit better than regular cabal sandboxes.
2015-03-09 07:14:00 +0100 <Javran> what about hsenv?
2015-03-05 21:51:33 +0100 <Javran> btw I compiled ghc 7.10, to get it to work with hsenv, how should I prepare the tarball file?
2015-02-22 05:49:58 +0100 <Javran> carter: I don't have alex local installed so I guess hsenv would be safer.. ok I'll try to compile it without hsenv
2015-02-22 05:48:25 +0100 <carter> Javran: dont use hsenv
2015-02-22 05:46:57 +0100 <carter> why are you trying to use hsenv though
2015-02-22 05:41:19 +0100 <Javran> can I use hsenv to compile ghc?
2015-02-17 15:47:06 +0100 <geekosaur> nschoe, there is also hsenv which sandboxes ghc installations. it's not very widely used though because that is usually overkill
2015-02-03 14:46:53 +0100 <geekosaur> hsenv sandboxes multiple ghc installations
2015-02-03 14:46:22 +0100 <hodapp> what about hsenv?
2015-02-01 19:13:29 +0100 <geekosaur> MrPopinjay, fgor multiple ghc releases there is hsenv
2015-01-18 20:02:46 +0100 <therp> johnw: tempting. is there a way without emacs? I am using hsenv, and I haven't set up the emacs integration yet.
