physacco / hash2array.lua
Created February 28, 2013 03:10
This gist presents 2 Lua functions for converting hash to array and vice versa. This is a common task in Redis Lua scripting.
-- $ lua hash2array.lua
-- print a table that contains numbers and strings only
local f_log_hash = function(hash, name)
if name ~= nil then
print(name .. ':')
end
for k, v in pairs(hash) do
print(k, ' => ', v)
end
