17:52:34 < goodgrue> Is there a way to change the environment
variables associated with Xmonad.Prompt.Shell at runtime? e.g. I'd
like to be able to modify $http_proxy and have that affect
subsequently launched processes.
17:55:31 < gwern> goodgrue: that'd be kind of hard. you could prepend
a mpodification of $HTTP_PROXY to each command
17:56:10 < gwern> ideally you'd modify xmonad's own environment
17:56:33 < goodgrue> gwern: yeah, the latter is what I was thinking
of. is that possible?
17:57:08 < gwern> shell uses `getEnv` from System.Environment but
there's no setEnv!
17:57:21 < gwern> if there were, you could probably bind it to a key
and use a prompt
17:58:44 < goodgrue> Hm...sounds like this may be a nice piece of
missing functionality. is there any reason you can think of that i
wouldn't be able to implement setEnv myself?
17:59:04 < gwern> http://hackage.haskell.org/trac/ghc/ticket/3587
17:59:14 < gwern> looks like 'putEnv' may be the real name
