Drupal 10 deprecated code

Problem/Motivation

Drupal 10 will be using Twig 3.0 → . Below is a list of deprecations found which will need to be fixed to be compatible with Drupal 10.

The spaceless tag is deprecated since Twig 2.7, use the "spaceless" filter with the "apply" tag instead. See https://drupal.org/node/3071078

• /templates/input/input--checkbox.html.twig
• /templates/input/input--file.html.twig
• /templates/input/input--form-control.html.twig
• /templates/input/input--radio.html.twig
• /templates/input/input--range.html.twig
• /templates/input/input--submit.html.twig
• /templates/input/input.html.twig
• /templates/input/select.html.twig
• /templates/navigation/toolbar.html.twig

Using an "if" condition on "for" tag is deprecated since Twig 2.10.0, use a "filter" filter or an "if" condition inside the "for" body instead (if your condition depends on a variable updated inside the loop). See https://drupal.org/node/3071078

• templates/dataset/forum-list.html.twig

Using the spaceless tag at the root level of a child template is deprecated since Twig 2.5.0 and will become a syntax error in 3.0. See https://drupal.org/node/3071078

• templates/input/input--form-control.html.twig

Nesting a block definition under a non-capturing node is deprecated since Twig 2.5.0 and will become a syntax error in 3.0. See https://drupal.org/node/3071078

• templates/input/input--form-control.html.twig

Value of core_version_requirement: ^9 is not compatible with the next major version of Drupal core.

• uswds_base.info.yml

Proposed resolution

• Determine if use of spaceless tag is needed in each template.
• Replace any spaceless tags with {% apply spaceless %}
• Fix all other deprecations.
