os.name in Lua filter

[pr-apes]

@pgundlach,

is there any way that I can use os.name in a filter?

package.config:sub(1,1) complains about package:config being nil (and this wouldn't allow distinctions inside Unix).

Many thanks for your help.

os.name is not available in the filter. Actually I don't use LuaTeX to interpret the filter file, I use https://github.com/yuin/gopher-lua.

print(package.config:sub(1,1)) works fine here.
