Below steps will be applied:

1. Find closest root dir of the go project with a go.mod file.
2. Set base to go module path defined in module field of go.mod.
3. Start from abs_path_of_main_or_lib.go, parse all imported packages that start with base.
4. Loop step 3 with imported packages until no files left.
