(Caveat: I do not really know lua regex, and have not tried out the
code)
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.
If it helps, the equivalent vim regex will be
\&\(.\{-}\);
I guess that $1 (the first group, that is everything that matches .-)
will be compared with mojcaentities table and replaced accordingly.
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.
