I wrote a little library for exactly this kind of package loading a few years ago: https://gitlab.com/dfinkel/goastpkg/-/blob/master/go_ast_parser.go (https://pkg.go.dev/golang.spin-2.net/astpkg) > > Playground example: https://play.golang.org/p/Yg30TTzoLHP > > My goal is to take multiple files, resolve inter file dependencies e.g. a > type referencing another type in a different file and process the resulting > ast.Files.
