Acknowledgments: ---------------- The author received useful remarks from the pdfTeX developers, especially Hahn The Thanh, and significant help from XeTeX developer Jonathan Kew Nota Bene: ---------- If you include or use a significant part of the synctex package into a software, I would appreciate to be listed as contributor and see "SyncTeX" highlighted. Version 1 Thu Jun 19 09:39:21 UTC 2008 Notice: ------- This file contains TeX changes for core synctex support. It is missing some implementation details that are deferred to either sync-pdftex.ch or sync-xetex.ch synctex.ch is based on tex.web after the eTeX changes have been applied. So it might not apply as is to pdftex.web due to some typographical changes. In the building process, one may have to apply some suitable tex.ch0 first. See pdftexdir for details. @x etex.ch l.3976 @= begin save_h:=cur_h; temp_ptr:=link(p); rule_wd:=width(p); free_node(p,small_node_size); @y @= begin save_h:=cur_h; temp_ptr:=link(p); rule_wd:=width(p); free_node(p,medium_node_size); {{\sl Sync\TeX}: p is a |math_node|} @z @x etex.ch l.4036 if type(p)=kern_node then if (rule_wd=0)or(l=null) then begin free_node(p,small_node_size); p:=l; end; @y if type(p)=kern_node then if (rule_wd=0)or(l=null) then begin free_node(p,medium_node_size); p:=l; end; @z @x etex.ch l.4088 @= begin free_node(p,small_node_size); link(t):=q; width(t):=rule_wd; edge_dist(t):=-cur_h-rule_wd; goto done; end @y @= begin free_node(p,medium_node_size); {{\sl Sync\TeX}: p is a |kern_node|} link(t):=q; width(t):=rule_wd; edge_dist(t):=-cur_h-rule_wd; goto done; end @z @x etex.ch l.4137 kern_node,math_node: begin r:=get_node(small_node_size); words:=small_node_size; end; glue_node: begin r:=get_node(small_node_size); add_glue_ref(glue_ptr(p)); glue_ptr(r):=glue_ptr(p); leader_ptr(r):=null; end; @y kern_node,math_node: begin words:=medium_node_size; {{\sl Sync\TeX}: proper size for math and kern} r:=get_node(words); end; glue_node: begin r:=get_node(medium_node_size); add_glue_ref(glue_ptr(p)); {{\sl Sync\TeX}: proper size for glue} glue_ptr(r):=glue_ptr(p); leader_ptr(r):=null; end; @z @x etex.ch l.4211 - Drop unused label procedure just_reverse(@!p:pointer); label found,done; @y procedure just_reverse(@!p:pointer); label done; @z @x etex.ch l.4234 found:width(t):=width(p); link(t):=q; free_node(p,small_node_size); @y width(t):=width(p); link(t):=q; free_node(p,small_node_size); @z @x etex.ch l.4241 begin type(p):=kern_node; incr(LR_problems); end else begin pop_LR; if n>min_halfword then begin decr(n); decr(subtype(p)); {change |after| into |before|} end else begin if m>min_halfword then decr(m)@+else goto found; type(p):=kern_node; end; end else begin push_LR(p); if (n>min_halfword)or(LR_dir(p)<>cur_dir) then begin incr(n); incr(subtype(p)); {change |before| into |after|} end else begin type(p):=kern_node; incr(m); end; end @y begin type(p):=kern_node; incr(LR_problems); {{\sl Sync\TeX} node size watch point: |math_node| size == |kern_node| size} end else begin pop_LR; if n>min_halfword then begin decr(n); decr(subtype(p)); {change |after| into |before|} end else begin if m>min_halfword then decr(m)@+else begin width(t):=width(p); link(t):=q; free_node(p,medium_node_size); {{\sl Sync\TeX}: no more "goto found", and proper node size} goto done; end; type(p):=kern_node; {{\sl Sync\TeX} node size watch point: |math_node| size == |kern_node| size} end; end else begin push_LR(p); if (n>min_halfword)or(LR_dir(p)<>cur_dir) then begin incr(n); incr(subtype(p)); {change |before| into |after|} end else begin type(p):=kern_node; incr(m); {{\sl Sync\TeX} node size watch point: |math_node| size == |kern_node| size} end; end @z
