Hi there,

I wonder if there is a faster... and better way to count a certain character in a string.  In this case, I want to know how many times the "\" is in a string. I've solved it this way, but there should be a better way.... hopefully. Any suggestions? :-)

-- little trick to count depth of folders...
		local _,_,weeknrcrap,crap = string.find(b,"Week%s+(%d+)\\(.*)")
		local count = 0
		while true do
			if string.match(crap,"\\") then
				s,e,crap = string.find(crap,"\\(.*)")
				count = count+1
			else
				break
			end
		end
		LogLine(hub,"debug",count.." times the '\\' in "..b)

OK... a new thought:
CountSlash = function(data)
   local count = 0 
   for slash in string.gmatch(data, "\\")
      count = count + 1
   end
   return count
end


This should be it.... I guess  :P
