Create a script that runs in a `pure` environment, in the sense that:
|
|
- the behavior is similar to `nix-shell --pure`
|
|
- `PATH` only contains exactly the packages passed via the `PATH` arg
|
|
- `NIX_PATH` is set to the path of the current `pkgs`
|
|
- `TMPDIR` is set up and cleaned up even if the script fails
|
|
- out, if set, is kept as-is
|
|
- all environment variables are unset, except:
|
|
- the ones listed in `keepVars` defined in ./default.nix
|
|
- the ones listed via the `KEEP_VARS` variable
|
|
'';

Creates a script in a `bin/` directory in the output; suitable for use with `lib.makeBinPath`, etc.
