string pattern

Hello everyone,

I need some help with strings and patterns.
To be exact patterns for gmatch. I know that I become with %w+ a whole word and numbers.

str = 'My teststring with numbers 1234 and some symbols!!! '
for word in string.gmatch(str, '%w+') do
  print(word)
end

My problem is, I don't get the symbols, but I need them.
Can anyone help me to understand how I use patterns exactly?

Thanks.

It looks like you want to match for things delimited by spaces. You can use the pattern %S+, which matches strings of characters which are not spaces. Note that case matters, and using lowercase 's' will only match spaces.

This is a good resource for the pattern-matching functions in Lua: http://www.lua.org/pil/20.1.html

Thanks that works fine.
But… I don't understand patterns at all. :(/>
Well. Maybe some time in the future.

%s+ is a pattern which matches for any number of space characters. The opposite pattern is %S+. Using this with the gmatch loop you were using gives you all characters of characters delimited by spaces.

Yes I know that. You say that in your post above.
But %w+, %s+ and so on are not the only part of patterns.
Anyway. It works now.
