[Feature request] libreadline

[yangfl]

I would greatly appreciate it if support for libreadline could be added to io interface, so that users can edit input with arrow keys, just like that in Python, bash, and many more others.

Could you check if the brew installed version of Io or earlier versions (somewhere before March) support arrow keys/readline? That worked for me before.
It looks like this bug has been introduced by some of the last commits.

yangfl, have you checked out the ReadLine addon?

[ales-tsurko]

@yangfl With current update you can install ReadLine or EditLine with Eerie.

@ales-tsurko I believe the issue-starter specifically asked for readline, not editline. It has been quite
some years since I last used Io; back then I think I had to use editline (this was really many years
ago, my knowledge is also only a fragmentation of what it once used to be now :-) ).

If support for readline is possible, I would recommend closing this issue here (and perhaps pointing
this out more clearly in the main README.md file, so that future visitors can be redirected here).

[ales-tsurko]

@rubyFeedback as I said then you can use either readline or editline — the both are available via addons system.

[ales-tsurko]

Note for me: to install readline/editline by default (as a global Eerie package).

[ales-tsurko]

Ah, no. It depends on the user's preferences. Moreover, including any of them by default will introduce readline/editline dependency. And as for unix-like systems it's fine, for Windows it isn't. So it's better to add note in the README.md instead.
