addAndAdjust

public void addAndAdjust(NodeList nodes,
                         TypesetterOptions context)

Add a node list to the current list maker and adjust the spacing between the elements of the list.

679. When a box is being appended to the current vertical list, the baselineskip calculation is handled by the append_to_vlist routine.

   procedure append_to_vlist(b:pointer);
    var d: scaled;  {deficiency of space between baselines}
    p: pointer;  {a new glue specification}
 begin if prev_depth>ignore_depth then
    begin d ? width(baseline_skip)-prev_depth-height( b);
    if d<line_skip_limit then p ? new_param_glue(line_skip_code)
      else begin p ? new_skip_param(baseline_skip_code); width(temp_ptr) ? d;  {temp_ptr=glue_ptr(p)}
      end ;
    link(tail) ? p; tail ? p;
    end ;
 link(tail) ? b; tail ? b; prev_depth ? depth(b);
 end ;
