It is more serious issue than expected. Consider next two variants:
(1) sentence, \index{primary}>Primary< (2) sentence,\index{primary} >Primary<
When the line is broken after a comma: ad 1) starting guillemet is not protruded ad 2) ending comma is not protruded
When \index is surrounded by spaces from both sides, the space is rendered at the beginning of the next line (resulting in 'indenting').
I'd be grateful for ignoring any non document content preceding punctuation to avoid its influence on protrusion.
well, think of it like this:
[something]<text>[something else]
with [something] being bound to < ... so that is then the boundary of the word, not < ... i might know a solution (but such -major- changes have to fit into my schedule)
are there any improvements here with revamped token processing implemented in recent versions?
it's not that trivial

Can you roughly estimate when this could be further investigated? Between 0.90-0.95, later or after 1.0?
further handling is unrelated to the engine because at that level it is not know what protrusion is expected (there are probably as many cases where you don't want to protrude as where you might want and hard coding solutions / heuristics is no option
I hope there will be some way to fix it in ConTeXt one day.
non trivial so very stepwise ... adding all kind of hacks just for protrusion can interfere with other mechanisms you can try to do this: \leftboundary\hbox{\index{foo}}.... ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Wow, I am quite satisfied with this solution. Btw, I couldn't find any details for that \leftboundary command either in TeX [1] or ConTeXt [2] command references. I've tried it just with \hbox{} and it works as well. Couldn't this be generalized in a way - if you want protrusion even in edge cases, any inline commands have to be wrapped in \hbox{} ?
