Add support for sub-packages
If you have a number of sub-packages that share a common repo, it can be very inconvenient to have to run go2nix save
in each package separately.
i've hacked together this script and it is a helper in getting the deps together.
using https://github.com/nixcloud/nix-beautify we can now generate nice and unique deps.nix files:
uniqueDeps.sh
#!/usr/bin/env bash
#https://groups.google.com/forum/#!topic/golang-nuts/611QEJqkDKw
#deps=$(go list -f {{.Deps}})
pushd nixcloud.io/auth-server/
deps=$(go list -f '{{join .Deps "\n"}}' | xargs go list -f '{{if not .Standard}}{{.ImportPath}}{{end}} ' | sort | uniq)
popd
rm -Rf mydeps
mkdir mydeps
for i in $deps; do
echo $i
pushd $i
go2nix save
popd
d=$(echo $i | base64)
cp $i/deps.nix mydeps/$d.nix
done
pushd mydeps
cat * | grep -v '\[' | grep -v '\]' | grep -v "This file was generated" > deps.nix
echo '[' > deps.nix_
cat deps.nix >> deps.nix_
echo ']' >> deps.nix_
mv deps.nix_ deps.nix
nix-instantiate --eval --strict -E 'let pkgs=import <nixpkgs>{}; in pkgs.lib.unique (import ./deps.nix)' | sed -e 's/};/};\n/g' | sed -e 's/} /}\n/g' | sed -e 's/{/{\n/g' | sed -e 's/; /;\n/g' > deps.nix_
popd
cat deps.nix_ | nix-beautify > deps.nix
@kamilchm might interest you, i've hacked https://github.com/nixcloud/dep2nix together
I'm less in Go now and I couldn't find time to complete my dep
branch. I'm glad someone did it 👍
