Hi all,
$ cat foo.lua
print( string.format("%08s","1100101"))
(so a one liner, nothing fancy).
On my Mac:
$ luatex foo.lua
01100101
on my Linux machine:
$ luatex foo.lua
1100101
(where is the leading 0??)
Mac: $ luatex --version
This is LuaTeX, Version beta-0.79.1 (TeX Live 2014) (rev 4971)
Linux: $ luatex --version
This is LuajitTeX, Version beta-0.79.1 (TeX Live 2014/dev) (rev 4972)
How can this difference show up? Is this something from "jit"?
on windows i get no leading 0 ... I think %s has no 'leading whatever'
spec, only a - for justification so I guess that interpreting the number
is library specific (apart from the fact that lua has some wrapper code
around format and jit probably overloads some)
just for fun i tried
\ctxlua{print(string.format("%a8i",1100101))}
which on linux gives
invalid option '%a' to 'format'
and on windows
0x1.0c9450p+208i
whatever that means
so one has to be real careful with what goes in front of a length specifier
