Created Text Operations

[s-p-n]

[Version: 0.0.2-11-chinchilla]

I added index and range selection to Texts. "bar"[1] will be "a". Here is an example:

/*
    Given a string, return a new string where the first and last chars have been exchanged. 
*/

var frontBack = (str: "") {
    return if str[0] is str[-1]:
        str;
    else:
        str[-1] & str[1:-1] & str[0];
    end;
};

print(frontBack("code"));   // eodc
print(frontBack("a"));      // a
print(frontBack("ab"));     // ba
print(frontBack("abba"));   // abba

You can use negative numbers on the second parameter to cycle backward through the text. You can also use negative numbers in regular indices. For example, "bar"[-1] is"r"`.

Arrays are unusable due to a regression.
