PHP API

The renderer can run without a Symfony kernel:

use Janalis\Doctrineviz\SchemaDotRenderer;

// $connection is an existing Doctrine DBAL Connection.
$schema = $connection->createSchemaManager()->introspectSchema();
$renderer = new SchemaDotRenderer();
$dot = $renderer->render($schema);
file_put_contents('schema.dot', $dot);

SchemaDotRenderer::render(Schema $schema, bool $inferGedmoTranslations = false, bool $inferGedmoLogs = false): string returns a complete DOT graph with no trailing newline. It does not connect to a database, launch Graphviz or write files. The console command adds a trailing newline.

Pass true as the second or third argument to opt in to translation or log inference:

$dot = $renderer->render($schema, inferGedmoTranslations: true, inferGedmoLogs: true);

Register custom types with DBAL before creating or introspecting the schema. The diagram uses their registered DBAL type names. Exceptions from the renderer propagate to PHP callers; the console command catches and sanitizes failures.
