Dear list,
The following Lua script behaves differently when executed in Lua vs.
LuaTeX.
print(os.execute("date"))
It seems that the definition of os_execute in loslibext.c was copied
over from Lua 5.1 and not adapted to newer versions.
$ lua5.1 test.lua
0
$ lua5.2 test.lua
true exit 0
$ lua5.3 test.lua
true exit 0
$ texlua test.lua
0
$ luajit test.lua
0
$ texluajit test.lua
0
As you can see from the example, this comes with the additional
complication that LuaJIT has Lua 5.1 behaviour and should also retain
that.
Cheers, Henri
