Notes Notes

Debug message is written to STDERR, and includes script execution time.

Helpful for optionally showing greater detail when needed. Used throughout
WP-CLI bootstrap process for easier debugging and profiling.

# Called in `WP_CLI\Runner::set_wp_root()`.
private static function set_wp_root( $path ) {
    define( 'ABSPATH', rtrim( $path, '/' ) . '/' );
    WP_CLI::debug( 'ABSPATH defined: ' . ABSPATH );
    $_SERVER['DOCUMENT_ROOT'] = realpath( $path );
}

# Debug details only appear when `--debug` is used.
# $ wp --debug
# [...]
# Debug: ABSPATH defined: /srv/www/wordpress-develop.dev/src/ (0.225s)
