cabalvchk

Verify installed package version against user-specified constraints.

Latest on Hackage:0.3

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

This utility can be used to verify the version of an installed package against version constraints. The version constraints can be specified in typical cabal fashion (e.g. >= 8.3, == 0.9.*, >= 8.3 && < 9.0).

Usage: cabalvchk package-name version-constraints [verbose]

Note that the version-constraints will probably need to be enclosed in single-quotes to prevent the shell from interpreting characters in the specification.

One use of this utility is by external configuration/validation utilities (e.g. autoconf) to verify installed package versions without running a cabal build. This utility produces no output (unless a third argument is specified) and the return value is 0 if the constraints are met or non-zero if the constraints are not met (including if the package is not installed).

Changes in 0.3:

  • Changed category to Distribution

  • Only consider exposed packages

Changes in 0.2:

  • Handles multiple package installations by returning 0 if any of the installed versions satisfies the constraints.
