= Access a non-flake package (not in nixpkgs)

////
$ mkdir tempwork
$ cd tempwork
$ cp ../flake.nix flake.nix
$ git add flake.nix
$ nix develop
$ git add flake.lock
$ git commit -a -m temp
////

In this example, we will use a nix package defined in a remote git repo.
However, you can use any of the flake reference styles defined in <<#flakeref>>.

[source,nix,linenums,highlight='5..7,17..20']
.flake.nix
....
$# cat flake.nix
....

Here's a demonstration using the shell.

....
$ hello-nix # this will fail
$# ../../../../../start-shell nix develop <<EOL
$ hello-nix
$# EOL
....

////
Good adoc0 scripts clean up after themselves.
$ cd .. ; rm -rf tempwork # clean up
