Incorrect type hinting in the smart_trim_tokens function

The fix looks good!

Related core issue. Probably string is correct but the regex is finding ints.

Created MR that applies to 2.x-dev branch and 2.3.1 release.

Although it pains me to remove strong typing, it does seem to be necessary in this case.

I note composer is failing for "next major". I think that is probably due to Drupal 12 development, and should probably be resolved in a separate issue.

Trust me, I agree. You could maybe opt to use a union type of int|string|float. Also, I think D12 is broken due to drush incompatibility with Symfony 8.

Environment

• Drupal: 11.4.1
• PHP: 8.5.5
• Database: MariaDB 10.11.16
• DDEV: v1.25.2
• smart_trim: 2.x-dev (MR !126, branch 3479519-incorrect-type-hinting)
• Browser: Chrome

Prerequisites

• smart_trim and its dependency token enabled.
• The module file declares strict_types=1, so the parameter type mismatch is enforced at call time.

Root cause

Core's token scanner returns the token type as an int when it is numeric (a token such as [12:57] yields type 12, because PHP casts numeric array keys to integers). The hook_tokens() implementation type-hinted string $type (and array $tokens), which does not match core's own hook_tokens() signature (unhinted). Under a strict caller this throws TypeError: Argument #1 ($type) must be of type string, int given.

Steps

1. Apply the fix from MR !126: remove the string hint from $type and the array hint from $tokens in the hook_tokens() implementation, matching core's unhinted signature.
2. Rebuild caches: ddev drush cr
3. Trigger token generation for a text that contains a numeric token type, e.g. [12:57], so the token type reaches the hook as an integer.
4. Observe that token generation completes without a TypeError.

Expected results

• A numeric token type (int) is accepted by the hook_tokens() implementation.
• Token generation completes with no TypeError.
• Normal [entity:field-smart-trim] token replacement continues to work.

Actual results

Before the fix, passing the scanned numeric token type (int 12) into the type-hinted string $type parameter under strict_types=1 raised TypeError: Drupal\smart_trim\Hook\SmartTrimTokenHooks::tokens(): Argument #1 ($type) must be of type string, int given. After removing the $type and $tokens hints, the same numeric token type is accepted and token generation completes without error, while existing smart-trim token replacement is unaffected.

Testing produced with the assistance of an LLM.

Still needs community review

I went ahead and updated the issue fork with latest from 2.x (we do not have a `smart_trim.tokens.inc` anymore.)

I usually prefer to type hint all method/function arguments, but since we're following an established pattern from Drupal core, I guess I'll have to get over it.

I am moving this back to "Needs work" for two reasons:

1. This change triggers a test failure in Drupal\Tests\smart_trim\Kernel\TokenTest::testSummaryFieldTokens ("Token value for [node:body-smart-trim] was not generated.")
2. All changes to Smart Trim require tests. So, we'll need a test to demonstrate that stuff like `[12:57] ` in the text to be smart trimmed doesn't fly off the rails due to code thinking that is a token.

I added two fixes on top of #13:

1. Restored #[Hook('tokens')]: Without it, the hook was no longer registered, which is what broke TokenTest::testSummaryFieldTokens.
2. Removed type hints from smart_trim_tokens(): I also removed them in smart_trim.module, because that file uses strict_types=1 and contains the function from the original bug report.

I also added a new test: TokenTest::testNumericTokenType(). It calls the hook implementations directly. This is necessary because Drupal core dispatches hooks from non-strict code (where integers are coerced into strings). By calling it directly, we can correctly reproduce and test the reported error ("TypeError: smart_trim_tokens(): Argument #1 ($type) must be of type string, int given").

Pipeline is green!

Thanks everybody - merged!
