The functionality will be included in avpops, but I cannot give an exact time line right now. There are a lot of operations that can be performed with avps and I should make a list with priorities, perhaps math operations with integers and string concatenation would be the first. Also, conversions from int to string and vice-versa...
string concatenation is probably the most valuable.
math with integer, can't think of an application.
conversions between int and string, would it be transparent to user? For example, inv-timeout uses int value. In avp_write("16", "s:inv-timeout"), we didn't specify if 16 is a number or not, is it string by default? Also in the db table, avp type is 0, meaning string value. We haven't encountered any problem.
