>I would like to propose a standard lua library. Written in Lua.

This is a good idea, because as has been mentioned in previous posts, Lua does
lack wider library support for scripting.

Nevertheless, I suggest some other name be chosen to avoid confusion with the
"standard libraries" that come with Lua, that is liblualib.a in Unix-speak.

I suggest a more flexible scheme: in stdlua.lua (or whatever the name is),
test whether a table called "stdlua" exists. If it does, then stdlua.lua should
define only those functions whose name appear in the table. In this way, users
can choose the functions they need.


stdlua={clone=1, strtrim=1}

In "stdlua.lua":

local select=stdlua
local L=settag({},newtag())
settagmethod(tag(L),"settable", function (i,v)
  if not select or stdlua[i] then rawset(L,i,v) end

function L.clone() ... end 
function L.strtrim() ... end 
function L.abort() ... end 


return L
