The bugs range from missing dependencies to logic errors and typos that could impact functionality and testing. + +## Bug 1: Missing Dependency Declaration for League CommonMark + +### **Severity:** High +### **Type:** Dependency Issue / Runtime Error +### **Location:** `src/Parser.php` line 271, `composer.json` + +### **Description:** +The code uses `\League\CommonMark\CommonMarkConverter` in the `generateFromMarkdown()` method to convert markdown content to HTML, but the `league/commonmark` package is not declared as a dependency in `composer.json`. This causes a fatal error when users try to process markdown content. + +### **Impact:** +- Fatal error: `Class '\League\CommonMark\CommonMarkConverter' not found` +- Complete failure of markdown processing functionality +- Poor user experience for anyone using markdown input + +### **Root Cause:** +The developer added markdown support but forgot to declare the required dependency. + +### **Fix Applied:** +Added `"league/commonmark": "^2.0"` to the `require` section in `composer.json`. + +```json +"require": { + "php": "^7.4 | ^8.0 | ^8.1 | ^8.2", + "statamic/cms": "^3.0 | ^3.1 | ^3.2 | ^3.3 | ^3.4 | ^4.0 | ^5.0", + "league/commonmark": "^2.0" +} +``` + +--- + +## Bug 2: Typo in Test Assertion + +### **Severity:** Medium +### **Type:** Logic Error / Testing Issue +### **Location:** `tests/Unit/ParserTest.php` lines 144-145 + +### **Description:** +In the `assertChild()` method of `ParserTest.php`, there's a typo where `has_hildren` is used instead of `has_children`. This causes the test to check for a non-existent property, leading to incorrect test behavior and false negatives. + +### **Impact:** +- Test doesn't properly validate the `has_children` property +- Could mask bugs in the children detection logic +- Reduces test coverage reliability + +### **Root Cause:** +Simple typo during test writing - `has_hildren` instead of `has_children`. + +### **Fix Applied:** +Corrected the property name in both the `isset()` check and the assertion: + +```php +// Before: +if (isset($child['has_hildren'])) { + $this->assertIsBool($child['has_hildren']); + +// After: +if (isset($child['has_children'])) { + $this->assertIsBool($child['has_children']); +``` + +--- + +## Bug 3: Logic Error in depth() Method + +### **Severity:** Medium +### **Type:** Logic Error / Calculation Bug +### **Location:** `src/Parser.php` lines 95-99 and 115-117 + +### **Description:** +The `depth()` method has a logic error in how it calculates the maximum heading level. When `from()` is called after `depth()`, it incorrectly recalculates the depth by passing the current `maxLevel` instead of the intended depth value, leading to incorrect heading level filtering. + +### **Impact:** +- Incorrect TOC generation when methods are chained in certain orders +- Headers might be incorrectly included or excluded from the TOC +- Inconsistent behavior depending on method call order + +### **Root Cause:** +The `from()` method calls `$this->depth($this->maxLevel)` instead of preserving and recalculating the original depth value. + +### **Fix Applied:** +1. **Fixed the depth calculation logic** to be clearer: + ```php + // Before: + $this->maxLevel = $depth + $this->minLevel - 1; + + // After: + $this->maxLevel = $this->minLevel + $depth - 1; + ``` + +2. **Fixed the from() method** to preserve the original depth: + ```php + // Before: + $this->minLevel = $start; + $this->depth($this->maxLevel); + + // After: + $currentDepth = $this->maxLevel - $this->minLevel + 1; + $this->minLevel = $start; + $this->depth($currentDepth); + ``` + +### **Test Case Example:** +```php +// This would previously fail: +$parser = new Parser($content); +$parser->depth(3)->from('h2'); // Would incorrectly calculate maxLevel + +// Now works correctly regardless of method order +``` + +--- + +## Additional Observations + +### **Potential Security Considerations:** +While not fixed in this report, the `injectIds()` method uses regex parsing for HTML which could be vulnerable to HTML injection attacks.
