RE: newRPL: Adding string processing commands?
Definitely SREV - reverse a string.
Convert string to list. In fact, I think it would be handy to have a function to convert any container sort of object into a list of the components. This would include arrays, matrices and, of course, composites. Or maybe a more generalized version of DOLIST and DOSUB - one that would iterate over any type of container object. Looking at the C++ string class, I see the following that might be handy and aren't(?) currently in RPL: back() - return the last character in a string. pop_back() - remove the last character rfind() - find the last occurence of the arg find_first_not_of() - find the first occurence of a char that is NOT in the arg. find_last_not_of() - find the last occurence of a char that is not in the arg. |
