Perhaps this one could be already useable for the OP:
function add_ties(line) line = line:gsub('( %a) ', '%1~') line = line:gsub('^(%a) ', '%1~') line = line:gsub('( %a)$', '%1~%%') return line end
Not working: $a = b + c$.
How about substituting with a macro \nonbreakbablespace (instead of ~) and redefining \nonbreakablespace to \relax using \everymathematics or \mathortext?
and then ending up with the same mess as usual ... exceptions, exceptions, exceptions ... just think of boxed text inside math which then needs to have it enabled again really, node lists is the way to go (although i admit that currently i do not handle math (also because it's a big todo in luatex) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
