Matthew Horsfall (alh) commented on CASSANDRA-4666:
---------------------------------------------------
A bit of interesting behaviour worth noting:
If you have a multi-line string as your last history line, and you hit the up
arrow and then enter, it will not add it to the history again. This is
intentional. However, if you type out the multi-line command that's already in
your history, Python's readline module will re-record the lines that you typed
so your multi-line command gets pushed back in the history.
> Add multi-line support to cqlsh history buffer

> The cqlsh tool has history support. If you press the up arrow, you get
> previous entries.
> If you do a multi-line command however like:
> {noformat}
> cqlsh > do
> something;
> {noformat}
> when you press the up arrow you get each individual statement separately.
> (First "something;" and then "do").
> This is not useful if you type a large create statement and typo one of the
> pieces.
> It'd be nice if cqlsh supported multi-line history items and could bring them
> back with the up arrow.
