Hi Christian, As long as there is a Knob in Kconfig to enable / disable each feature (that defaults to disable) the impact is 0.
IIRC there is a history, and some fancy-ness that was added by Dave a while ago. Good docs and an example defconfig would will keep it maintained (and built). Once we have scripted test running against the sim (or real HW) test cases will keep it from breaking.

At a minimum to colour the prompt. I had been thinking this is something i could develop and propose to come back into the mainline as a nsh kconfig option. But before i do, the obvious question is, has this been proposed before and are there reasons we wouldn’t want this in NuttX? I’m also thinking it would be good to have a single line of command history. Other configurable options could be clear screen on nsh entry (I added this as my app was using ANSI line positioning and resets back into nsh looked messy). There are all sorts of fun things which could be done with ANSI terminal emulation. Thanks, See you all tonight. Where you’ll see my demo going crazy with ANSI colour codes. Christian
