hi folks! :)
Lua 5.3.3 Copyright (C) 1994-2016 Lua.org, PUC-Rio
> print(('aaa x bbb'):match'(.-) x (.*)')
(lj 2.0.5 does this as well)
i would expect that the 1st capture should be empty without a `^` at
the beginning of the pattern, as the manuals (up to lua 5.4) say:
"a single character class followed by '-', which also matches zero or
more repetitions of characters in the class. Unlike '*', these
repetition items will always match the shortest possible sequence;"
am i wrong here?
(((actually it came from here:
thx for any info and all the bests to all of u! :)
