The Windows registry useful to determine installation paths of other software and whatnot. I've hacked together some code using the REG QUERY command: https://github.com/JuliaStats/RCall.jl/blob/e4ba35cf45ca2eb041f660642449b8259c2f30e3/deps/build.jl#L13 but it is somewhat complicated (and potentially unreliable) to parse.
Has anyone had any luck using the C interface? It looks a little complicated, so if anyone has any examples, I would be grateful. I guess ideally we would want to wrap the C interface into package, similar to _winreg in Python: https://docs.python.org/2/library/_winreg.html Perhaps we need an "up for grabs packages" list? s P.S. On that note, perhaps we should put the Julia installation path in the registry, for other software that might need to find it: both R and Python do it.
