Can I view in which mode I am while using vi-mode for terminal (xterm)?

The question is pretty self explanatory. I've heard from a co-worker there is a way to view in which mode I currently am when using vi-mode in terminal but somehow he forgot how it's done and I couldn't find an answer to that question. How can I do it?

This is a readline feature. To enable it, you have to set

set show-mode-in-prompt on

in your ~/.inputrc file. This requires readline 6.3 or newer (bundled with Bash 4.3 or newer).

In vi mode, the mode strings then default to (ins) and (cmd):

(cmd)$
(ins)$

This assumes that your prompt is simply PS1='\$ '.

You can customize them with two other readline settings, for example

set vi-cmd-mode-string [c]
set vi-ins-mode-string [i]

resulting in

[c]$
[i]$

Notice that non-printing characters (like terminal escapes for colours) have to be escaped with \1 and \2. These two settings require readline 7.0 or newer (bundled with Bash 4.4 or newer).
