Re: Is there a replacement for \tracechinesetrue in mkiv?

[Zhichu Chen <zhichu.chen@gmail.com>]

All right, after some readings, I came out with a node solution. The
major idea is listed below and works just fine. "n" from node_traverse
(head) and n.id==node.id ('glyph')

My question is: is there a better way? Because these codes are so
dirty. I prefer mplib but I have no clue how to do that.

=============================================
          local ht,wd,dp = n.height,n.width,n.depth ;
          local rwd = .5*65536
          local k1 = node.new('kern')
          k1.kern = -wd-.5*rwd
          local r1 = node.new("rule")
          r1.width, r1.height, r1.depth = rwd, ht, dp
          local k2 = node.new('kern')
          k2.kern = -r1.width
          local r2 = node.new("rule")
          r2.width, r2.height, r2.depth = wd+rwd, ht+.5*rwd, -ht+.5*rwd
          local k3 = node.new('kern')
          k3.kern = -r2.width
          local r3 = node.new("rule")
          r3.width, r3.height, r3.depth = wd+rwd, -dp+.5*rwd, dp+.5*rwd
          local k4 = node.new('kern')
          k4.kern = -.5*rwd
          local r4 = node.new("rule")
          r4.width, r4.height, r4.depth = rwd, ht, dp
          local k5 = node.new('kern')
          k5.kern = -.5*rwd
          k1.next = r1
          r1.prev = k1
          r1.next = k2
          k2.prev = r1
          k2.next = r2
          r2.prev = k2
          r2.next = k3
          k3.prev = r2
          k3.next = r3
          r3.prev = k3
          r3.next = k4
          k4.prev = r3
          k4.next = r4
          r4.prev = k4
          r4.next = k5
          k5.prev = r4
          local box = node.hpack(k1)
          local tb = node.vpack(box)
          insert_after (head, n, tb)
