[Dev-luatex] lpeg/setmaxstack unknown

[Patrick Gundlach]

Hi,

this fails:

\directlua{
  lpeg.setmaxstack(12345)
}
\bye




~/TeX/luatex/test$ luatex test
This is LuaTeX, Version beta-0.70.2-2012062819 (TeX Live 2012)
 restricted \write18 enabled.
(./test.tex
! LuaTeX error <\directlua >:1: attempt to call field 'setmaxstack' (a nil valu
e)
stack traceback:

l.3 }
     

WTF??? :))

(seriously: it's in the lpeg documentation - but I guess the 0.70.2 has an old version of lpeg? Perhaps without setmaxstack)?
