-- Create a generic file translator to the resource instance directory. local resRoot = fileCreateTranslator( "/" ); -- Change into another directory. resRoot:createDir( "myDir/" ); resRoot:chdir( "myDir/" ); -- Output the path relative to the current directory and relative to the translator root directory. local thePath = "someDir/../myFile.txt"; local relativeToCurrent = resRoot:relPath( thePath ); local relativeToRoot = resRoot:relPathRoot( thePath ); outputChatBox( "input-path: " .. thePath ); outputChatBox( "relative-to-current: " .. relativeToCurrent ); outputChatBox( "relative-to-root: " .. relativeToRoot );
