PkgEnv
Session Example
We start creating a new package environment:
hypermac:trash paolo$ pkgenv binary.env Using GHC 6.10.1 (full path: /opt/local/bin/ghc-6.10.1) Using cabal-install 0.6.2 (full path: /Users/paolo/.cabal/bin/cabal) Installing package environment in /Users/paolo/trash/binary.env. Done! Usage: bash> source /Users/paolo/trash/binary.env/bin/activate (binary.env)bash> deactivate bash> hypermac:trash paolo$
We activate the new environment (the bash prompt is changed accordingly):
hypermac:trash paolo$ source binary.env/bin/activate (binary.env)hypermac:trash paolo$
All tools run now by default on the system package DB and the newly created/empty user package DB:
(binary.env)hypermac:trash paolo$ ghc-pkg list /opt/local/lib/ghc-6.10.1/./package.conf: Cabal-1.6.0.1, HUnit-1.2.0.3, QuickCheck-1.2.0.0, array-0.2.0.0, base-3.0.3.0, base-4.0.0.0, bytestring-0.9.1.4, containers-0.2.0.0, directory-1.0.0.2, (dph-base-0.3), (dph-par-0.3), (dph-prim-interface-0.3), (dph-prim-par-0.3), (dph-prim-seq-0.3), (dph-seq-0.3), editline-0.2.1.0, filepath-1.1.0.1, (ghc-6.10.1), ghc-prim-0.1.0.0, haddock-2.3.0, haskell-src-1.0.1.3, haskell98-1.0.1.0, hpc-0.5.0.2, html-1.0.1.2, integer-0.1.0.0, mtl-1.1.0.2, network-2.2.0.1, old-locale-1.0.0.1, old-time-1.0.0.1, packedstring-0.1.0.1, parallel-1.1.0.0, parsec-2.1.0.1, pretty-1.0.1.0, process-1.0.1.0, random-1.0.0.1, regex-base-0.72.0.2, regex-compat-0.71.0.1, regex-posix-0.72.0.3, rts-1.0, stm-2.1.1.2, syb-0.1.0.0, template-haskell-2.3.0.0, time-1.1.2.2, unix-2.3.1.0, xhtml-3000.2.0.1 /Users/paolo/trash/binary.env/ghc-packages.conf:
Let's install a package inside the new environment:
(binary.env)hypermac:trash paolo$ cabal install --verbose=0 binary Reading package info from "dist/installed-pkg-config" ... done. Writing new package config file... done. (binary.env)hypermac:trash paolo$ ghc-pkg list /opt/local/lib/ghc-6.10.1/./package.conf: Cabal-1.6.0.1, HUnit-1.2.0.3, QuickCheck-1.2.0.0, array-0.2.0.0, base-3.0.3.0, base-4.0.0.0, bytestring-0.9.1.4, containers-0.2.0.0, directory-1.0.0.2, (dph-base-0.3), (dph-par-0.3), (dph-prim-interface-0.3), (dph-prim-par-0.3), (dph-prim-seq-0.3), (dph-seq-0.3), editline-0.2.1.0, filepath-1.1.0.1, (ghc-6.10.1), ghc-prim-0.1.0.0, haddock-2.3.0, haskell-src-1.0.1.3, haskell98-1.0.1.0, hpc-0.5.0.2, html-1.0.1.2, integer-0.1.0.0, mtl-1.1.0.2, network-2.2.0.1, old-locale-1.0.0.1, old-time-1.0.0.1, packedstring-0.1.0.1, parallel-1.1.0.0, parsec-2.1.0.1, pretty-1.0.1.0, process-1.0.1.0, random-1.0.0.1, regex-base-0.72.0.2, regex-compat-0.71.0.1, regex-posix-0.72.0.3, rts-1.0, stm-2.1.1.2, syb-0.1.0.0, template-haskell-2.3.0.0, time-1.1.2.2, unix-2.3.1.0, xhtml-3000.2.0.1 /Users/paolo/trash/binary.env/ghc-packages.conf: binary-0.4.4
We can now use the new package:
(binary.env)hypermac:trash paolo$ ghci GHCi, version 6.10.1: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done. Loading package integer ... linking ... done. Loading package base ... linking ... done. Prelude> import Data.Binary Prelude Data.Binary>
and leave the environment:
(binary.env)hypermac:trash paolo$ deactivate hypermac:trash paolo$
and when you're done with the environment, simply remove it:
hypermac:trash paolo$ rm -rf binary.env
