<div dir="ltr"><span class="im">Hello,<br><br>When a user first starts the racket repl, it doesn't
do line editing due to licensing issues. For example, it would be nice
if the default editor would give the previous line if you hit up arrow,
rather than writing "^[[A".<br><br></span><div>I have now pointed out
xrepl to several users, and every time they always ask me why it's not
the default repl. Apparently the problem is that xrepl uses GNU
Readline, which is GPL. However, Asumu found that if we replace
requiring readline with BSD's libedit (not libeditline), everything
works fine due to libedit's readline compatibility. It doesn't have all
of the features of readline, but it does have some of the biggest ones
(such as being able to use arrow keys)<br><br></div>What do you all think of having `(require editline)` that works for
the default repl, so that it gets line editing features. This would
allow us to also keep `(require readline)` as before, maintaining
backwards compatibility.<div><div><img class="" src="https://ssl.gstatic.com/ui/v1/icons/mail/images/cleardot.gif"><br>If
we do do this, this leads to the question of distribution. Would we
want to include libedit inside Racket distributions, or should we just
link to whatever the user has on their system?</div></div><div class=""><div id=":22m" class="" tabindex="0"><img class="" src="https://ssl.gstatic.com/ui/v1/icons/mail/images/cleardot.gif"></div></div><div><div class="gmail_signature"><div dir="ltr"><div><br></div>~Leif Andersen</div></div></div>
