Constant Summary collapse

@@counters =

Counters for generating element IDs. This is a hash from the element ID prefix, to another hash that maps the element type name to a count.

For backwards compatibility, counters always start at -1, and must be incremented before being used. This ensures that element ids start at 0. This is NOT compatible with AKN 3.0 which requires that element numbers start at 1.

eg.

section-1 => paragraph => 2

Hash.new{ |h, k| h[k] = Hash.new(-1) }
