Assuming lua follows standard regex syntax, this means
& # The letter & ( # start a group .. # any character - # As few as needed ) # end group ; # the letter ;
so this will match all entities.
just &(.-); with () being the capture
If it helps, the equivalent vim regex will be \&\(.\{-}\);
I guess that $1 (the first group, that is everything that matches .-)
%1
will be compared with mojcaentities table and replaced accordingly.
indeed
This looks like a really nice feature of lua. In Ruby and Vim, I often find myself writing a bunch of similar regex, and always wished there was something like what lua does.
the nice thing about many lua feature is that less code (lua c code) behaves more powerful ----------------------------------------------------------------- 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 -----------------------------------------------------------------
