You can check for syntax errors in Twig templates using the twig:lint console command:

# You can check by filename:
$ php app/console twig:lint
src/Acme/ArticleBundle/Resources/views/Article/recentList.html.twig

# or by directory:
$ php app/console twig:lint src/Acme/ArticleBundle/Resources/views

# or using the bundle name:
$ php app/console twig:lint @AcmeArticleBundle
