could you explain the purpose of these changes? it seems like only the if immediately_execute below all this should be necessary to accomplish the change, but not sure what you had in mind.

Thanks for the review! Now that I see how github displays the change, I am confused as well. All of this is indentation, except for the if !immediately_execute. I think that github confuses the two instances of events.push(crossterm::event::read()?);.

The point is that I don't want reedline to read from stdin when it is in immediately_accept mode. So I skip all these conditional/looped input reads and further down add the Submit to the queue.

I'm so sorry for missing some of the calls. Now, clippy should pass |
Description
Pass a boolean value
immediately_executeto each invocation ofget_line.This way, the nu command
commandline editcan accept a flag--acceptand not only edit the currently, but also immediately execute the result.API
The API severely changes, as now this flag has to be passed to
get_lineandget_line_helper.This could be changed to a channel, but then the initialization of the module would get more complicated.
