added ".*" at the end of the pattern. I'd assume that would not change
anything, but it does:
lpeg=require"lpeg"
require"re"
print("lpeg version", lpeg.version())
x = {re.find('hello', [[ { 'h' . . } { . } { . } .* -> {} ]])}
print(type(x), #x, x[1], x[2], x[3], x[4], x[5])
print(type(x[4]), #x[4], x[4][1])
print(type(x[5]), #x[5], x[5][1])
prints
lpeg version 0.8
table 5 1 hel l o table: 0xa854e0
string 1 nil
table 0 nil
So now I get the 3rd capture in x[4] as expected, but still an
additional (empty) table as the last element
