Re: Emulating advanced regex features using Lua patterns and pure Lua code

[Wim Couwenberg <wim.couwenberg@...>]

My strategy is to match more than you want and then filter the results in code:

local text = string.match(haystack, "^[fb][oa][or]$)
if text == "foo" then
  ...
elseif text == "bar" then
  ...
else
  -- no match
end

Takes a little preprocessing of the pattern but I prefer 100% lua code
over package dependencies any time and the Lua code is fairly trivial.
