I was trying to customize iex prompt so that it will show different env name(by reading it from system env) in release mode. The purpose is to alert myself that I am interacting with a shell in one env(so that it’s harder to mistake production shell as staging shell).
However it looks like IEx.configure has no effect in remote console. I wonder if someone know what’s reason? And is there other workaround to do the customize prompt thing in release?
Remote consoles are fun in that your prompt is on a local instance but the process executing what you type is remote. So, you might be configuring the wrong prompt. It might work to take self/0 (the process executing what you type), run it through Process.group_leader/1, take its node, then RPC a call to IEx.configure there. Pretty does this in reverse to get your local console’s inspection settings. It’s something like this:
