Just as a point of reference, I manually implemented my own solution for this.  I have all my wireguard key files named as `<hostname>.pub` in a directory, then I source the following as one of my dot files:


#!/usr/bin/env bash


# Don't do anything if `wg` doesn't exist

if [[ -z $(which wg) ]]; then

    return

fi


# Otherwise, load in our mapping of public keys to hostnames:

# Otherwise, load in our mapping of public keys to hostnames:

declare -A WG_HOST_MAP

for f in ${HOMES_PATH}/etc/secure/wireguard/*.pub; do

    HOST=$(basename "${f%.*}")

    KEY=$(cat "$f")

    WG_HOST_MAP["${KEY}"]="${HOST}"

done


function wg()

{

    # Do some special parsing for `wg show`

    if [[ -z "$1" ]] || [[ "$1" == "show" ]]; then

        WG_OUTPUT=$(unbuffer sudo -n $(which wg))

        for K in "${!WG_HOST_MAP[@]}"; do

            V="${WG_HOST_MAP["${K}"]}"

            WG_OUTPUT="${WG_OUTPUT/"${K}"/"${V}"}"

        done

        echo "${WG_OUTPUT}"

    else

        # Pass through to actual `wg` otherwise

        sudo -n $(which wg) "$@"

    fi

}

export -f wg



You’ll notice that it automatically calls `sudo -n` on things, and that it requires `unbuffer`, which is usually installed alongside `expect`, so that it can capture the output of `wg` retaining the color codes.

i really would love to have a feature like wireguard-hosts file.
whereas wg command would print given "name" instead of key - so the
output would be more meaningfull
We have some wireguard running in server like infrastructure, where one
server serves dozens of "clients"

so instead of
peer: l9FxaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaU=
we would have something alike
peer: superhero downtown

some of you may be familar with batman-adv layer2 routing protocol,
there they also have a batctl which is working pretty similar to wg tool.
there you can add a bat-hosts file which is doing the job, which totaly
works likes any hosts file
a normal hosts file maps ip to name,
a bat-hosts file maps mac addresses to name,
a wg-hosts file would map keys to name.

i found the sources for bat-hosts ( .c .h .sample ) here
https://downloads.open-mesh.org/batman/releases/batman-adv-2019.5/batctl-2019.5.tar.gz

is this something maybe usefull to other also?
is there a chance to have this implemented by default?

thx for answers.
