Installing `texmath` binary as dependency in Nix project

[jgm]

I can't help with nix, but to get the executable you need to set the executable flag when compiling, e.g. -fexecutable when using cabal.

This did it:

let
  pkgs = import <nixpkgs> {};
  texmath = pkgs.haskellPackages.texmath;
  texmath-executable = pkgs.haskell.lib.addBuildDepends (pkgs.haskell.lib.enableCabalFlag texmath "executable") [ pkgs.haskellPackages.network-uri ];
in
pkgs.mkShell {
  buildInputs = [
    texmath-executable
  ];
}
