Nix.Derivation

Use this package to parse and render Nix derivations such as those stored in /nix/store/*.drv files. For example, if you had the following derivation saved at /nix/store/zzhs4fb83x5ygvjqn5rdpmpnishpdgy6-perl-MIME-Types-2.13.drv:

Derive([("devdoc","/nix/store/15x9ii8c3n5wb5lg80cm8x0yk6zy7rha-perl-MIME-Types-2
.13-devdoc","",""),("out","/nix/store/93d75ghjyibmbxgfzwhh4b5zwsxzs44w-perl-MIME
-Types-2.13","","")],[("/nix/store/57h2hjsdkdiwbzilcjqkn46138n1xb4a-perl-5.22.3.

)])

... you could parse that derivation using:

Example3 expressions

>>> text <- Data.Text.Lazy.IO.readFile "/nix/store/zzhs4fb83x5ygvjqn5rdpmpnishpdgy6-perl-MIME-Types-2.13.drv">>> let result = Data.Attoparsec.Text.Lazy.parse Nix.Derivation.parseDerivation text>>> resultDone "" (Derivation {outputs = fromList [("devdoc",DerivationOutput {path = FilePath "/nix/store/15x9ii8c3n5wb5lg80cm8x0yk6zy7rha-perl-MIME-Types-2.13-devdoc", hashAlgo = "", hash = ""}),("out",DerivationOutput {path = FilePath "/nix/store/93d75ghjyibmbxgfzwhh4b5zwsxzs44w-perl-MIME-Types-2.13", hashAlgo = "", hash = ""})], inputDrvs = fromList [(FilePath "/nix/store/57h2hjsdkdiwbzilcjqkn46138n1xb4a-perl-5.22.3.drv",fromList ["out"]),(FilePath "/nix/store/cvdbbvnvg131bz9bwyyk97jpq1crclqr-MIME-Types-2.13.tar.gz.drv",fromList ["out"]),(FilePath "/nix/store/p5g31bc5x92awghx9dlm065d7j773l0r-stdenv.drv",fromList ["out"]),(FilePath "/nix/store/x50y5qihwsn0lfjhrf1s81b5hgb9w632-bash-4.4-p5.drv",fromList ["out"])], inputSrcs = fromList [FilePath "/nix/store/cdips4lakfk1qbf1x68fq18wnn3r5r14-builder.sh"], platform = "x86_64-linux", builder = FilePath "/nix/store/fi3mbd2ml4pbgzyasrlnp0wyy6qi48fh-bash-4.4-p5/bin/bash", args = ["-e","/nix/store/cdips4lakfk1qbf1x68fq18wnn3r5r14-builder.sh"], env = fromList [("AUTOMATED_TESTING","1"),("PERL_AUTOINSTALL","--skipdeps"),("buildInputs",""),("builder","/nix/store/fi3mbd2ml4pbgzyasrlnp0wyy6qi48fh-bash-4.4-p5/bin/bash"),("checkTarget","test"),("devdoc","/nix/store/15x9ii8c3n5wb5lg80cm8x0yk6zy7rha-perl-MIME-Types-2.13-devdoc"),("doCheck","1"),("installTargets","pure_install"),("name","perl-MIME-Types-2.13"),("nativeBuildInputs","/nix/store/nsa311yg8h93wfaacjk16c96a98bs09f-perl-5.22.3"),("out","/nix/store/93d75ghjyibmbxgfzwhh4b5zwsxzs44w-perl-MIME-Types-2.13"),("outputs","out devdoc"),("propagatedBuildInputs",""),("propagatedNativeBuildInputs",""),("src","/nix/store/5smhymz7viq8p47mc3jgyvqd003ab732-MIME-Types-2.13.tar.gz"),("stdenv","/nix/store/s3rlr45jzlzx0d6k2azlpxa5zwzr7xyy-stdenv"),("system","x86_64-linux")]})

... and render the result back to the original derivation:

Example1 expression
