Re: word boundary \b (regular expression) in Lua

[Zhe Hu <iamhuzhe@...>]

Hi,
Thank you very much for the help. I guess the following line solved my problem.

print(string.gsub("the cat in the hat", "%f[%w](%w)", function (s)
return " "..string.upper(s) end))

However, it seems still not a look-around. It eats up the " " between words. 


Sincerely,
Hu Zhe
