# This script will proxy commands for the bitwarden CLI, intercepting them to
# get or set a # session token for seamless use between shells and other programs.
# Make sure this script is in your $PATH, so you can simply run 'bw' like you
# normally would.

# If you have a $HOME/bin dir that is at the front of your $PATH, you should be
# able to use this as an install method:
# curl https://raw.githubusercontent.com/mjslabs/bitagent/master/examples/bw > $HOME/bin/bw && chmod 0755 $HOME/bin/bw

# You will want to make sure that $bwcmd below is the full path to the real
# bitwarden cli. The default is 'bwcli' stored in ~/bin

# Installation of the real bitwarden CLI
bwcmd="${HOME}/bin/bwcli"
# Default socket location
basock="${HOME}/.bitagent.sock"
# This assumes you've run a `go install` to install bitagent
bitagent="${GOBIN:-${HOME}/go/bin}/bitagent $basock"

# If our socket doesn't exist then run bitagent
if [[ ! -e $basock ]]; then
  $bitagent 1>/dev/null & disown
