Im working on my c++ application, and I have string (user input) where I
would have to replace some variables/substrings in it..
For example lets say user give input:
string str "this is test $some_variable some more text $random(1-5)
My program has a vector <string> of variables that program should look for,
for this case lets say "some_variable" and "random".
Now I want to replace $some_variable and both $random 'variables' with
another string, and I want $some_variable to be replaced with some other
string, and $random to be replaced with random number generated in range
from 1-5 and 1-9, for instance $random(1-5) = "3", $random(1-9) = "6".
So I would get "this is test some string some more text 3 6";
This would be an easy thing to do, if I wouldnt have $random variable which
makes different string each time you call it, so I'm in concern what would
be a right/best approach to this.. I was thinking of using boost::regex and
search with boost::regex
until I come to the string end..
Thanks a lot for help
