# 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!"
|
|
'')
|
|
|

];
