Lua Selector

• Follows pan.Selector interface
• Has additional SetPreferences feature
• Supports state querying and manipulation via JSON() callback

Lua API

Lua scripts needs to implement the following functions:

-- gets called when a set of paths to addr is known
function panapi.Initialize(prefs, laddr, raddr, ps)

function panapi.SetPreferences(prefs, laddr, raddr)

-- gets called for every packet
-- implementation needs to be efficient
function panapi.Path(laddr, raddr)

-- gets called whenever a path disappears
function panapi.PathDown(laddr, raddr, fp, pi)

function panapi.Refresh(laddr, raddr, ps)

function panapi.Close(laddr, raddr)

function panapi.Periodic(seconds)

Lua scripts can call the following functions from the panapi module:

panapi.Log(...)

panapi.Now()
