− | === Session Example === |
||
− | |||
− | We start creating a new package environment: |
||
− | |||
− | <pre> |
||
− | 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$ |
||
− | </pre> |
||
− | |||
− | We activate the new environment (the bash prompt is changed accordingly): |
||
− | |||
− | <pre> |
||
− | hypermac:trash paolo$ source binary.env/bin/activate |
||
− | (binary.env)hypermac:trash paolo$ |
||
− | </pre> |
||

− | All tools run now by default on the system package DB and the |
||
− | newly created/empty user package DB: |

− | |||
− | <pre> |
||
− | (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> |
||
− | </pre> |
||
− | |||
− | and leave the environment: |
||
− | |||
− | <pre> |
||
− | (binary.env)hypermac:trash paolo$ deactivate |
||
− | hypermac:trash paolo$ |
||
− | </pre> |
||
− | |||
− | and when you're done with the environment, simply remove it: |
||
− | |||
− | <pre> |
||
− | hypermac:trash paolo$ rm -rf binary.env |
||
− | </pre> |
