What are the names of all function from the Lua 5.3 string library?

Question:

Here is a function name register closure which I use to register library names:

The Pool object:

function FooBarPool()
  local Names = {}
  local self = {}
    function self:Register(fFoo,sName)
      if(fFoo) then
        Names[fFoo] = sName
      end
    end
    function self:GetName(fFoo)
      return Names[fFoo] or "N/A"
    end
  return self
end

Create a Pool object

local Pool = FooBarPool()

Register known library functions

Pool:Register(string.sub,"string.sub")
Pool:Register(string.gsub,"string.gsub")
Pool:Register(string.match,"string.match")
Pool:Register(string.gmatch,"string.gmatch")
Pool:Register(string.find,"string.find")
Pool:Register(string.gfind,"string.gfind")
Pool:Register(string.format,"string.format")
Pool:Register(string.byte,"string.byte")
Pool:Register(string.char,"string.char")
Pool:Register(string.len,"string.len")
Pool:Register(string.lower,"string.lower")
Pool:Register(string.upper,"string.upper")
Pool:Register(string.rep,"string.rep")
Pool:Register(string.reverse,"string.reverse")

for k,v in pairs(string) do
  print(tostring(v) .. " : "..Pool:GetName(v))
end

If you add print(k,v) to your last loop, you'll see that you're missing string.dump.

The function string.gfind is not standard. It was present in Lua 5.0 but was renamed to string.gmatch in Lua 5.1.

You can get all the names in the string library with

for k in pairs(string) do
    print(k)
end

or see the manual.
