direnv allow

# Upgrade venv
pip install -U setuptools pip wheel

# Install uv
pip install uv

# Install application in development mode
uv sync --active [--extra=ldap] [--extra=markdown] [--extra={pgsql-src|pgsql-bin}] [--extra=radius]
invoke i18n.generate

# Install ESLint
npm install --save-dev

# Copy and adapt configuration files
cp -a conf .conf
cp -a env.dist env.local

# Initialize database
phelpers-init-db .conf/application.ini

# Run web server in development mode
invoke service.httpd

# Run static and functional tests:
invoke test
