How to reduce duplication in the build-depends fields of a .cabal file?

cabal, haskell

Solution

Since version 2.2 Cabal supports common stanzas, to dedup build info fields: https://cabal.readthedocs.io/en/latest/developing-packages.html#common-stanzas

cabal-version:       2.2
name:                myprogram
version:             0.1
-- blah blah blah

common deps
  build-depends: base ^>= 4.11,
                 -- long long list of packages
  ghc-options: -Wall

library
  import: deps
  exposed-modules: Foo

test-suite tests
  import: deps
  type: exitcode-stdio-1.0
  main-is: Tests.hs
  build-depends: foo

Problem

Here's a .cabal file: ``` Name: myprogram Version: 0.1 -- blah blah blah Cabal-version: >=1.9.2 Executable myprogram HS-source-dirs: src Main-is: Main.hs Build-depends: attoparsec == 0.10.*, base == 4.3.*, -- long long list of packages Test-Suite test HS-source-dirs: test, src Type: exitcode-stdio-1.0 Main-is: Main.hs Build-depends: attoparsec == 0.10.*, base == 4.3.*, -- long long list of packages QuickCheck == 2.4.* ``` Is there any way I can replace the long list of build-depends packages for the test suite with "same as for the executable, plus QuickCheck"? Edit: version information. - cabal-dev 0.9 - cabal-install 0.10.2 - Cabal library 1.10.2.0 - GHC 7.0.4 - Haskell Platform 2011.4.0.0
