Cannot use nix-shell as shebang interpreter

[ttuegel]

I cannot use nix-shell as an interpreter. For instance, this example from the manual:

#! /usr/bin/env nix-shell
#! nix-shell -i python -p python pythonPackages.prettytable

import prettytable

# Print a simple table.
t = prettytable.PrettyTable(["N", "N^2"])
for n in range(1, 10): t.add_row([n, n * n])
print t

produces this output:

$ ./example.py
error: not an absolute path: ‘././example.py’

Any other example produces the same output.

I am using this version

$ nix-shell --version
nix-shell (Nix) 1.12pre4911_b30d1e7

This is a big deal! Is there plans for addressing this or creating a special tool for shebangs? They're awfully useful :3.

This appears to work fine for me.

I think I remember being affected by this once on Nix 1.12, but when I tested just now, it was fine.

@dtzWill @ttuegel can you confirm that you still have this issue?

Edited to add the output of nix-info:

• system: "x86_64-darwin"
• host os: Darwin 17.5.0, macOS 10.13.4
• multi-user?: yes
• sandbox: no
• version: nix-env (Nix) 2.0
• channels(root): "nixpkgs-18.03pre115958.bed076cdfb"
• nixpkgs: /etc/nix-darwin/pkgsets/nixpkgs/darwin

Indeed, it seems to work for me now as well!

Closing as it works now.
