local path = "/path/to/somewhere"
local lfs = require("luafilesystem")
local posix = require("posix")
if (posix.access(path,"x")) then
for f in lfs.dir(path) do
...
end
end
The problem is that between the posix.access() test and the lfs.dir() call the permissions on path could change.
What I would like instead is some way to ignore the error that lfs.dir() is causing. Normally one can ignore errors with pcall() but I don't see how to use pcall with an iterator like lfs.dir().
Does anyone know how to do that? To make the problem any harder, any solution must work with Lua 5.1+
Thanks,
