Get path of filename

[Ivo]

I want to write a function to get the path of a filename in a LÖVE program, and am finding it difficult. getDir('/usr/local/bin/sl') should return '/usr/local/bin'. I essentially want to remove the last item in a filename. In python I would just do:

Code: Select all

def getDir(sPath):
  dir = '/'.join(sPath.split('/')[:-1])
  return dir

but as far as I know lua does not have the split or the join functions.

Something like this:

Code: Select all

function getDir(filepath)
    return filepath:match("(.+)/") or ""
end

It will return a string containing everything up to the last '/' in the filepath, or an empty string if there isn't any '/'.

worked perfectly, thanks!
