I've just had a report that WordGrinder is failing on a system with a
Portugese locale. This turns out to be because it's got localised errno
strings. So, my code, which does this:
local fp, e = io.open("somefile")
if e and not e:find("No such file or directory") then
dosomething()
end
...gets confused, because the actual string in e is "Arquivo ou
diretório não encontrado".
I *could* do something really evil:
local _, filenotfound = io.open("/this/file/is/guaranteed/missing")
if e != filenotfound then
dosomething()
end
...but I can't really guarantee that the path doesn't exist.
What I'd really prefer is an errno (and a set of errno constants). But
Lua doesn't expose those. Any suggestions?
