Apparently, it’s valid for a cabal file to have key-value pairs
without a space, e.g.
benchmark benchmarks
type: exitcode-stdio-1.0
main-is:Speed.hs
hs-source-dirs:test
default-language: Haskell2010
build-depends:
base < 5,
criterion,
diagrams-core,
diagrams-lib
from http://hackage.haskell.org/package/diagrams-lib-1.4.2.3/revision/2.cabal
guix import hackage breaks on this:
$ guix import hackage diagrams-lib
Importing `diagrams-lib` from hackage
Syntax error: unexpected token : main-is:Speed.hs (at line 175, column 2)
Syntax error: unexpected end of input
guix import: error: failed to download cabal file for package 'diagrams-lib'
