This is the beginnings of a new API that allows Devbox to query the Nix
store without needing to call out to the nix command. So far, it can
list installed packages and determine their dependencies.
`go doc` summary of the new types:
type PackageStore struct {
fs.FS
// Has unexported fields.
}
PackageStore is a file system containing packages that are compatible with
Devbox.
func LocalNixStore(path string) *PackageStore
func (p *PackageStore) Package(name string) (Package, error)
type Package struct {
fs.FS
// Name is the full name of the package that is unique to its store.
Name string
// DirectDependencies are the other packages in the store that this
// package depends on. It does not contain transitive dependencies.
DirectDependencies []Package
}
Package is a file system that contains a package's files and metadata.
The go.mod + go.sum changes are from a `go get -u ./... && go mod tidy`.
