Show multiline's answer in new line

[AielloChan]

Now, it looks wired:

How about showing the answer in a new line, just like below:

[AielloChan]

And it just needs to add a \n in the template.

So, any idea?

Thanks for the ping @AielloChan! It's been hard to wrangle all of the different notifications I get so I appreciate your patience.

At the moment, a change like this would be considered a break in the API. survey is used by many large companies who run integration tests and a change like this would inevitably make those fail.

I know its not the answer you or the others want to hear but I dont think we can change this at the moment. I will leave the issue open and tag it for future consideration though!

Okay, this would be the best choice for now. 😄

I agree with @AielloChan the current behavior bugged me as-well. I am just staring with Go so am I far from being one which could provide any implementation advice nor I fully understand how survey is internally working.

Given the templating engine of Go and an extension of PromptConfig it should be possible to flag this feature. So no integration test on larger companies will break

[graugans]

After checking the source code I guess PromptConfig will change the behavior of all prompts. What do you think about this:

Of course the tests are missing. But would that be something acceptable?

I'm running into this styling issue myself as well currently. The solution proposed by @graugans seems like a good option to me. What do you think @AlecAivazis?

@AlecAivazis would a PR just adding that missing line break to the go template be acceptable? I don't mind submitting that. I noticed pterm input and some other tools do this so it's only the survey library that I've noticed the multiline editing on the same line happen in. It's a minor "nit" but it's sufficiently jarring to users that I figured I'd see if I could help get this through.
