Hello, I am trying to compile luatex examples from http://luatex.bluwiki.com . How could I make it work with ConTeXt? The following fails. ----------------------------------------------------------------------------------------------------------------------------------- \directlua0{ local glyph = node.id('glyph') local hlist = node.id('hlist') local vlist = node.id('vlist') function gothru(h,prof) for t in node.traverse(h) do texio.write_nl(string.rep("...",prof) .. 'NODE type=' .. node.type(t.id) .. ' subtype=' .. t.subtype ) if t.id == hlist or t.id == vlist then texio.write(' w=' .. t.width .. ' h=' .. t.height .. ' d=' .. t.depth .. ' s=' .. t.shift ) gothru(t.list,prof+1) end if t.id == glyph then texio.write(' font=' .. t.font .. ' char=' .. t.char .. ' width=' font.fonts[t.font].characters[t.char]['width']) end end end callback.register('pre_linebreak_filter', function(h) gothru(h,0) return true end ) } \starttext bla bla bla bla \stoptext ------------------------------------------------------------------------------------------------------- best Piotr -- http://okle.pl
