Subject: LuaTeX incompatible with Lua
Date: Thu, 21 Nov 2019 20:17:04 +1300 [thread overview]
Message-ID: <9303d3b5-d2b8-5d80-4f19-3e1f59cdb2d8@gmail.com> (raw)
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
