-- Auto PathMap.scriptlib
-- by Stefan Ihringer <stefan@bildfehler.de>, 2013-03-05

-- This scriptlib, if placed in the Scripts: folder will be automatically executed whenever Fusion
-- is started. It will check for the existence of files and then set a global path map entry based
-- on which file was accessible.
-- This way, comps can use a path mapping (e.g. "Host:") in loaders that will always point to
-- the footage. You can use this to share a comp between artists on different locations, take your
-- comp and a copy of the footage with you on a laptop while travelling or use a virtual machine like
-- Parallels on a Mac (where the Mac's hard drive is mapped to a virtual network share) without the
-- need to search&replace path names.

-- name of the path mapping
AUTOMAP = "Host:"

-- Possible values for the path map and their corresponding probe files.
-- The first one that is found wins.
-- Remember to use double back slashes inside LUA strings.
OPTIONS = {{"E:\\",      "Users\\.DS_Store" },	-- Mac partition under Bootcamp
           {"\\\\psf\\", "Host\\.DS_Store"}}	-- Virtual network share inside Parallels
-- more examples:
-- {"\\\\server\\footage", ".footagedrive"}		-- hidden probe file on a network share of main studio
-- {"Y:\\",                "projects.txt"}		-- an external artist on his own machine/network
