Running nix-build example.nix on https://nixos.org/channels/nixos-unstable is unsuccessful.

What I tried:
I tried to modify default.nix by changing the arguments to
{ nixpkgs ? import {}
, idris_plain ? nixpkgs.haskellPackages.callPackage ./idris_plain {
cabal = nixpkgs.haskellPackages.cabal-install;
inherit (nixpkgs.haskellPackages) annotatedWlPprint ansiTerminal ansiWlPprint
base64Bytestring binary blazeHtml blazeMarkup boehmgc
cheapskate deepseq filepath fingertree gmp happy haskeline
lens libffi mtl network optparseApplicative parsers safe
split text time transformers trifecta unorderedContainers
utf8String vector vectorBinaryInstances xml zlib
fetchFromGitHub ;}
}:

which yields
1 markus@nixos ~/git/idris/idrispkgs (git)-[master] % nix-build example.nix :(
error: attribute ‘mkDerivation’ missing, at /home/markus/git/idris/idrispkgs/idris_plain/default.nix:10:1

So it seems, I need to inject a variable "cabal" that has mkDerivation defined. Unfortunately, I do not know enough about nix yet to do that.

Thank you very much.

Looks like I need to do the same as in hackage-packages.nix, possibly renaming the packages (camelcase to snakecase).

Example:
"idris" = callPackage
({ mkDerivation, annotated-wl-pprint, ansi-terminal, ansi-wl-pprint
, base, base64-bytestring, binary, blaze-html, blaze-markup
, boehmgc, bytestring, cheapskate, containers, deepseq, directory
, filepath, fingertree, gmp, happy, haskeline, lens, libffi, mtl
, network, optparse-applicative, parsers, pretty, process, safe
, split, text, time, transformers, transformers-compat, trifecta
, uniplate, unix, unordered-containers, utf8-string, vector
, vector-binary-instances, xml, zip-archive, zlib
}:
mkDerivation {
pname = "idris";
version = "0.9.18.1";
