Shell history not included when using io:read/1 in OTP 27

Hi,

When I’m using OTP-27, it seems like the Erlang shell history does not include what I type in
as a response to a io:read/1 prompt. I guess it has to do with the improved Erlang shell?

A bit unfortunate for tools like edbg that provides it’s own “prompt-session”, so I wonder if
it could be solved somehow, e.g by tapping into the shell history mechanism somehow?

Cheers, Tobbe

That change was introduced in 26. To get line history you need to send get_until I/O requests.

In 28 there is a new option for io:setopts/2 that you can use that explicitly allows you to say whether you want a read request to end up in the shell history or not.

Aha, great, thanks!
