#
# A Drush wrapper.
#
# Legacy drush is based on system-wide installs, while recent versions support only
# installations using composer:
#
# * https://docs.drush.org/en/master/install/
# * https://docs.drush.org/en/8.x/install/
#
# This simple wrapper makes a system to support both at the same time by using a
# simple heuristic: if there's a `vendor/drush` starting from the current folder,
# then it uses drush-launcher, falling back to drush legacy otherwise.

# Parameters
BIN="/usr/local/bin"

# Set drush implementation
if [ ! -d "vendor/drush" ]; then
  DRUSH="$BIN/drush-legacy"
else
  DRUSH="$BIN/drush-launcher"
fi

# Dispatch
$DRUSH "$@"
