Suppose we have the following folder structure:

|-- Repo
|   |-- Data
|   |   |-- Sets
|   |   |   |-- Set1.json
|   |-- Tests
|   |---|-- Case1
|   |---|---|-- main.go

If I want to access the Set1.json file, how would I do that from main.go? Suppose I’m allowed to provide the relative path with respective to repo, i.e. Repo/Data/Sets would be provided. Is there a way for me to immediately figure out the absolute path involving that relative path on any system?

My solution was using os.Getwd to get the current location and then use:

tmp := filepath.Dir(filepath.Dir(currDir))

To get to the sibling of the parent of the folder where main.go was. Then I just do:

res := filepath.Join(tmp, "Data/Sets") 
Or
res := filepath.Join(tmp, "Data\Sets")

And this would get me the absolute path to the Sets folder. Is there a smarter way to get there somehow? It should work on any system.
