14−description:
15− The @cabal2nix@ utility converts Cabal files into Nix build instructions. The
16− commandline syntax is:
17− .
18− > Usage: cabal2nix [options] URI
19− > -h --help show this help text
20− > -v --version print version
21− > --hackage-db=FILEPATH path to the local hackage db in tar format
22− > --sha256=HASH sha256 hash of source tarball
23− > -m MAINTAINER --maintainer=MAINTAINER maintainer of this package (may be specified multiple times)
24− > -p PLATFORM --platform=PLATFORM supported build platforms (may be specified multiple times)
25− > -f FLAG --flag=FLAG Cabal flag (may be specified multiple times)
26− > --jailbreak don't honor version restrictions on build inputs
27− > --no-haddock don't run Haddock when building this package
28− > --no-check don't run regression test suites of this package
29− > --rev=REVISION revision, only used when fetching from VCS
30− > --no-hyperlink-source don't add pretty-printed source code to the documentation
31− > --shell generate output suitable for nix-shell
32− >
33− > Recognized URI schemes:
34− >
35− > cabal://pkgname-pkgversion download the specified package from Hackage
36− > cabal://pkgname download latest version of the specified package from Hackage
37− > http://host/path fetch the Cabal file via HTTP
38− > file:///local/path load the Cabal file from the local disk
39− > /local/path.cabal abbreviated version of file URI
40− > <git/svn/bzr/hg URL> download the source from the specified repository
41− .
42− The only required argument is the path to the cabal file. For example:
43− .
44− > cabal2nix http://hackage.haskell.org/packages/archive/cabal2nix/2.0/cabal2nix.cabal
45− > cabal2nix cabal://cabal2nix-2.0
46− .
47− If the @--sha256@ option has not been specified, cabal2nix calls
48− @nix-prefetch-url@ to determine the hash automatically. This causes
49− network traffic, obviously.
50− .
51− If the argument refers to a source repository instead of a cabal file,
52− cabal2nix will use that source repository to fetch from instead of hackage.
53− Currently, cabal2nix supports directories, archives (fetched via http or https) and
54− git, mercurial, svn or bazaar repositories.
