I think this can be modelled as a string array and an index showing
where the active part starts:
import std;
struct Notes {
string[] whole;
size_t activeIndex;
void add(string line) {
whole ~= line;
}
string[] activeText() {
return whole[activeIndex..$];
}
void wipeText() {
++activeIndex;
}
}
void main() {
auto input = [ "I went for a walk and fell down a hole.",
"There was a D guy on the roof.",
"That was a tricky problem!", ];
Notes notes;
// add() to add()
input.each!(line => notes.add(line));
// activeText() will show the active part
// wipeText() will move forward
}
