@Add(global elements)
void insert_before(const std::string &prefix,
std::vector<std::string> &c

}
@End(global elements)
-
function to interactively insert lines at the end of the container
-
the
prefix is the prompt that is printed
3
@Add(run loop)
if (cmd == "l" || cmd == "list") {
insert_before("l", curBlock->notes);
continue;
}
@End(run loop)
-
the
list or l command adds notes
4
@Add(run loop)
if (cmd == "a" || cmd == "add") {
std::string prefix;
@put(find add prefix);
insert_before(prefix, curBlock->value);
continue;
}
@End(run loop)
-
the
add or a command adds value lines
5

prefix = "h"; break;
case RS::code:
prefix = "c"; break;
case RS::para:

}
@end(find add prefix)
-
one character prefix for the different block types

int next = c.size();
@Put(do str range);

for (;;) {
@put(insert next line);
break;
}
draw_block();
@end(insert before)
-
insert strings at the end of the container
7

c.insert(c.begin() + next, l);
++next;
continue;
@end(insert next line)
-
read lines until a single
. is read
-
spaces at the beginning of the line are stripped
