# init-dev.sh — Reset and initialise the InvoiceShelf dev environment.
#
# Run this script INSIDE the PHP container:
#
#   docker exec -it invoiceshelf-dev-php bash /var/www/html/docker/development/init-dev.sh [options]
#
# Safe to re-run at any time, including after switching git tags/branches.
# Always does a full clean slate: fresh DB, cleared caches, reinstalled deps.
#
# Usage:
#   init-dev.sh [--db=sqlite|mysql|pgsql] [--seed] [--no-seed]
#
#   --db=sqlite   Use SQLite (default — no external DB container needed)
#   --db=mysql    Use MariaDB  (requires docker-compose.mysql.yml)
#   --db=pgsql    Use PostgreSQL (requires docker-compose.pgsql.yml)
#   --seed        Seed the database with fake dev data (DevDataSeeder)
#   --no-seed     Skip seeding (default)
#
# Examples:
#   init-dev.sh                          # sqlite, no seed
#   init-dev.sh --seed                   # sqlite + fake data
#   init-dev.sh --db=mysql --seed        # MariaDB + fake data
#   init-dev.sh --db=pgsql --no-seed     # PostgreSQL, no seed
