internal scripts: use pinned, cached pkgs
Instead of setting up the script PATH via nix-shell, use
`nix shell` with inputs from the nix-bitcoin flake.
Advantages:
- Uses the nixpkgs version from the nix-bitcoin flake instead of
`<nixpkgs>` from the user env (NIX_PATH), so the script runtime
env is reproducible.
- The pkg derivations for the runtime env are cached, which greatly
increases script startup speed.
This commit was generated by running the following script inside the
repo root dir:
def transform(path, src)
if src =~ /#! *nix-shell +-i +bash +-p +(.*)/
pkgs = $1
if src =~ /^.*?(set -e.*?pipefail)\n/
set_statement = $1
src.sub!($&, '')
end
src.sub!(/\A.*?#! *nix-shell.*?\n/m, '')
parents = ([ '..' ] * (path.split('/').count - 1)).join('/')
[
'#!/usr/bin/env bash',
*set_statement,
%(. "${BASH_SOURCE[0]%/*}/#{parents}/helper/run-in-nix-env" "#{pkgs}" "$@"),
nil,
src
].join("\n")
end
end
Dir['**/*.sh'].each do |f|
src = File.read(f)
if new_src = transform(f, src)
puts "Changed file #{f}"
File.write(f, new_src)
