Hi Guixers,
What's the current recommended way to do this in Guix?
#!/usr/bin/env nix-shell
#!nix-shell -i python3 -p "python3.withPackages(ps: [ ps.numpy ])"
import numpy as np
a = np.array([1,2])
b = np.array([3,4])
print(f"The dot product of {a} and {b} is: {np.dot(a, b)}")

or this shebang pinned to a particular commit?
#!/usr/bin/env nix-shell
#!nix-shell -i python3 -p "python3.withPackages(ps: [ ps.numpy ])"
#!nix-shell -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/d373d80b1207d52621961b16aa4a3438e4f98167.tar.gz
import numpy as np
a = np.array([1,2])
b = np.array([3,4])
print(f"The dot product of {a} and {b} is: {np.dot(a, b)}")

Something like:
--8<---------------cut here---------------start------------->8---
#!/usr/bin/env -S guix shell python -- python3
import numpy as np
a = np.array([1,2])
b = np.array([3,4])
print(f"The dot product of {a} and {b} is: {np.dot(a, b)}")
--8<---------------cut here---------------end--------------->8---
works for me.
And to answer your other question about specific revision, I would do:
--8<---------------cut here---------------start------------->8---
#!/usr/bin/env -S guix time-machine --commit=29efa27 -- shell python -- python3
import numpy as np
a = np.array([1,2])
b = np.array([3,4])
print(f"The dot product of {a} and {b} is: {np.dot(a, b)}")
--8<---------------cut here---------------end--------------->8---
Cheers,
simon

Hi, thanks!!
Should we document this approach in the manual somewhere?
If so, where would be a good place to mention how to do this?
