I think we should revert this; this breaks linenoise integration in nim secret, making it painful to use s a REPL.

before this PR: we can use the usual bash/zsh-like navigation to edit cmdline
after this PR: each keyboard interaction (eg left arrow to move cursor when editing cmdline) creates a newline

The (minor) annoyance you're observing is fixable though.

links

• change the [Processing] messages into dots #14418 which introduced dots
• compile time echo steals newline from stderr so it's included in stdout instead #16334 which is an issue caused by dots that was recently fixed, see fix #16334 #16335

[ringabout]

Let me think.
Could you give me some screenshots?

I will fix this differently soon.

[timotheecour]

after clicking on left arrow a few times:

(might be easier to fix in a linux vm to see this behavior rather than windows ;-) )

[ringabout]

Oh, I see.

[timotheecour]

in future work, we should probably add some tests for nim secret (at least a few basic ones, to prevent regressions); this should be doable despite stdin interaction using osproc (iirc inim has some like that but this can be done rather simply)

(EDIT: basic tests in #16495)

[ringabout]

How to compile nimsecret quick? It's painful to debug it.
I use koch temp --d:useLinenoise secret now.

[ringabout]

It is reverted now.
#16483

Use nim secret in Linux, when pressing up button

use rlwrap like this: rlwrap nim secret, and up button will provide you access to history. Also editing works it even has a vi mode if you care about that. You need to install rlwrap though.
