name: cabalvchk version: 0.3 synopsis: Verify installed package version against user-specified constraints. description: 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. . category: Distribution license: BSD3 license-file: LICENSE author: Kevin Quick maintainer: build-type: Simple cabal-version: >= 1.2 Executable cabalvchk Main-is: ghcpkgchk.hs Build-Depends: base >= 4 && < 5, Cabal > 1.10 && < 2 ghc-options: -Wall
