yookoala / drush_launch_function.sh
Created June 14, 2024 10:30
A replacement bash function for the old drush launcher
#!/bin/bash
#
# Drush launcher no longer works in Druapl 10 because of
# the TTY check in the new Symfony's Process implementation.
#
# This script search for a "vendor/bin/drush" in the current
# folder herichey and proxy parameters to that drush. Feels
# like old launcher behaviour.
