Hi,
For those who like playing around you can use lua pettern matching in a
match loop:
\starttext
\doloopovermatch
{(\letterpercent w+) *(\letterpercent w*)}
{aa bb cc dd}
{
[
\doloopovermatch
{(\letterpercent w)(\letterpercent w)}
{#1}
{(##1 ##2)}
\doloopovermatch
{(\letterpercent w)(\letterpercent w)}
{#2}
{(##1 ##2)}
]
}
\blank
\doloopovermatch
{(\letterpercent d+)}
{this 1 is 22 a 333 test}
{ [#1] }
\blank
\doloopovermatch
{(.-)\letterpercent{\bf (.-)\letterpercent}(.*)}
{this is {\bf a} test}
{#1{\it not #2}#3}
\blank
\doloopovermatch
{([\letterpercent w]+)}
{\cldloadfile{tufte.tex}}
{ [#1] }
\stoptext
Probably not that useful (I never needed it but that doesn't say much)
but it fits in the repertoire of loops.
