Use string.gsub to replace strings, but only whole words

Question

I have a search replace script which works to replace strings. It already has options to do case insensitive searches and \"escaped\" matches (eg allows searching for % ( et

do you mean if you pass nocase() foo, you want [fooFOO] instead of [fF][oO][oO]? if so, you could try this?

function nocase (s)
      s = string.gsub(s, "(%a+)", function (c)
            return string.format("[%s%s]", string.lower(c),
                                           string.upper(c))
          end)
      return s
end

and if you want an easy way to split a sentence into words, you can use this:

function split(strText)
    local words = {}
    string.gsub(strText, "(%a+)", function(w)
                                    table.insert(words, w)
                                  end)
    return words
end

once you've gotten the words split, it's pretty easy to iterate over the words in the table and do a full comparison against each word.
