nix library extension, containing sophisticated script and code generator functions.
# How to include as overlay
```
{ config, pkgs, ... }:
let
# fetch the repository
# ------------------
# nix-prefetch-git is your friend to create this part.
nix-writers = (import <nixpkgs> {}).fetchgit {
url = "https://cgit.krebsco.de/nix-writers";
rev = "c8d71ce6acbae124a7bc162323442979a1d6df06";
sha256 = "0r1p34a3jvm55v5sbkfbjpqcld2cbdrvc5685g723b1frhw666ag";
};
in {
# include the repository as overlay
nixpkgs.config.packageOverrides = import "${nix-writers}/pkgs" pkgs;
...
}
```
# How to use the scripts
once you've included the nix-writers as overlay you can use the scripts to create to create binaries (for example)
```
environment.systemPackages = with pkgs; [
# Haskell example
(writeHaskellPackage "nix-writers-example-haskell" {
executables."nix-writers-example-haskell".text = ''
main = print "this is a writeHaskell example"
'';
})
# C example
(writeC "nix-writers-example-c" {
destination = "/bin/nix-writers-example-c";
} ''
int main() { printf("this is a writeC example!\n"); }
'')
# Dash example
(writeDashBin "nix-writers-example-dash" ''
echo "this is a writeDash example!"
'')
];
```
