@hackage cabal-bounds1.0.5

A command line program for managing the bounds/versions of the dependencies in a cabal file.

'cabal-bounds' is able to do these things with the bounds of the dependencies in the cabal file:

• drop them

• update them by the library versions of the current cabal build

• update them by the library versions of a haskell platform release

• update them by the library versions specified by a file

• dump the libraries/dependencies and their lower bound versions from the cabal file(s) into a file

For further details please consult the README.

Installation

You have to ensure, that the Cabal library of 'cabal-bounds' matches the one used by the cabal binary:

$ cabal --version
cabal-install version 1.18.0.2
using version 1.18.1 of the Cabal library

$ cabal install --constraint="Cabal == 1.18.1" cabal-bounds

If you update the cabal binary and the used Cabal library changes, then you have to rebuild 'cabal-bounds'.

Issues

Perhaps the currently most annoying thing is, that you have to live with the reformating of your cabal file done by the pretty printer of the Cabal library.

To reformat your cabal file without changing any bounds you can call 'cabal-bounds' with the name of a section that isn't present in the cabal file:

$ cabal-bounds drop --executable=blub
