Re: [Nix-dev] Handling nix-shell shebangs with the new nix command

[Shea Levy]

Hi Eelco,

Hmm, I already whipped up a generic solution for long shebangs [1] and
there's the start of a nix build command already. With that already done
it seems likely to be easier to just write a nix shell command rather
than porting nix-shell, why do you think it's preferable to do
otherwise?

Well, there is no "nix shell" command yet. Given that the "nix" command is
experimental at the moment, it's probably best to keep nix-shell a separate
program for now.

I wonder what the progress of the „getting rid of perl“ thingy is?
This is the first time it has come up in months, how far along is it?

[Nix-dev] Handling nix-shell shebangs with the new nix command

[Shea Levy]

Hi Eelco,

For the perl->c++ work, how should we handle nix-shell shebangs given
that the command is now "nix shell"? Should the nix command itself
contain shebang-checking logic, or should we have a separate nix-shell
C++ program just for shebangs, or something else?

Thanks,
Shea
