#!/bin/sh

## Short script to startup two local nodes with
## bitcoind, all running on regtest
## Makes it easier to test things out, by hand.

## Should be called by source since it sets aliases
##
##  First load this file up.
##
##  $ source contrib/startup_regtest.sh
##
##  Start up the nodeset
##
##  $ start_ln
##
##  Let's connect the nodes.
##
##  $ l2-cli getinfo | jq .id
##    "02b96b03e42d9126cb5228752c575c628ad09bdb7a138ec5142bbca21e244ddceb"
##  $ l2-cli getinfo | jq .binding[0].port
##    9090
##  $ l1-cli connect 02b96b03e42d9126cb5228752c575c628ad09bdb7a138ec5142bbca21e244ddceb@localhost:9090
##    {
##      "id" : "030b02fc3d043d2d47ae25a9306d98d2abb7fc9bee824e68b8ce75d6d8f09d5eb7"
##    }
##
##  When you're finished, clean up or stop
##
##  $ stop_ln  # stops the services, keeps the aliases
##  $ cleanup_ln # stops and cleans up aliases
