/batchskill for TYPO3 contexts. Target: TYPO3 v14.x only.
Orchestrate large-scale, parallelizable changes across a TYPO3 codebase. Decompose work into 5–30 independent units, present a plan, then execute each unit with verification.
composer normalize / php -l / PHPStan after PHP changesvendor/bin/phpunit)Research: Find all entries in $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS'] and
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF'].
Decompose: One unit per hook class.
Per unit:
1. Identify the hook interface/method
2. Find the corresponding PSR-14 event (see mapping below)
3. Create new event listener class with #[AsEventListener]
4. Move logic from hook method to __invoke()
5. Remove hook registration from ext_localconf.php
6. If **not** using `#[AsEventListener]`: register the listener in `Services.yaml`. With the attribute and `autoconfigure: true` (default), no extra `tags:` entry is required.
7. Run php -l on new file
Hook → event mapping (verify in Core event lists):
DataHandler (
t3lib/class.t3lib_tcemain.php): TYPO3 Core does not expose generic PSR-14 events named likeBeforeRecordOperationEvent/AfterRecordOperationEventunderTYPO3\CMS\Core\DataHandling\Event. For datamap/cmdmap reactions, useSC_OPTIONShook classes (see typo3-datahandler §9). Do not “migrate” those hooks to non-existent events.
| Hook / legacy API | Typical direction |
|---|---|
processDatamap_afterDatabaseOperations / related SC_OPTIONS | Keep processDatamapClass hook methods (no 1:1 Core event) |
processDatamap_preProcessFieldArray | Keep hook or narrow Core events for your table/field if documented |
processCmdmap_postProcess | Keep processCmdmapClass hook methods |
drawHeaderHook | ModifyPageLayoutContentEvent (Breaking #96526) |
drawFooterHook | ModifyPageLayoutContentEvent (Breaking #96526) |
checkFlexFormValue | Still often a hook; AfterFlexFormDataStructureParsedEvent is for DS parsing, not a drop-in for validation — confirm in Core for your case |
PageRenderer render hooks (render-preProcess, render-postProcess) | No 1:1 PSR-14 replacement; prefer PSR-15 middleware for render-pipeline manipulation |
tslib_fe->contentPostProc (cached) | AfterCacheableContentIsGeneratedEvent |
tslib_fe->contentPostProc (output) | No PSR-14 event — use a PSR-15 middleware (Deprecation #91012); AfterCachedPageIsPersistedEvent replaces insertPageIncache, not this hook |
tslib_fe->contentPostProc (all) | AfterCacheableContentIsGeneratedEvent (Breaking #97862; also covers usePageCache) |
BackendUtility->getPagesTSconfig | ModifyLoadedPageTsConfigEvent |
generatePageTSconfig | ModifyLoadedPageTsConfigEvent |
Not 1:1 replacements (verify before batch-rewriting):
drawHeaderHook / drawFooterHook — Page module header/footer integration points. Replaced by ModifyPageLayoutContentEvent (Breaking #96526), which lets listeners add or change header and footer content; ModifyButtonBarEvent covers the button bar only and is not the migration target.tslib_fe->contentPostProc — Sub-hooks (all, cached, output) run at different FE pipeline stages. Map cached and all (plus usePageCache) → AfterCacheableContentIsGeneratedEvent, and insertPageIncache → AfterCachedPageIsPersistedEvent (Breaking #97862); output has no PSR-14 event — use a PSR-15 middleware instead.Research: Scan all Configuration/TCA/ and Configuration/TCA/Overrides/ files.
Decompose: One unit per TCA file.
Per unit:
1. Replace 'eval' => 'required' → 'required' => true
2. Replace 'eval' => 'trim' → keep where trimming is desired (trim is NOT applied by default)
3. Replace 'eval' => 'null' → 'nullable' => true
4. Replace 'eval' => 'int' → 'type' => 'number'
5. Replace 'renderType' => 'inputDateTime' → 'type' => 'datetime'
6. Replace 'renderType' => 'inputLink' → 'type' => 'link'
7. Replace 'renderType' => 'colorPicker' → 'type' => 'color'
8. Replace 'type' => 'input', 'eval' => 'email' → 'type' => 'email'
9. Convert items arrays: [0] => label, [1] => value → ['label' => ..., 'value' => ...]
10. Remove boilerplate columns auto-created from `ctrl` on TYPO3 v14: hidden, starttime, endtime, fe_group, language fields
11. Use palettes for enablecolumns: visibility → hidden, access → starttime, endtime
12. Remove convention fields from ext_tables.sql (auto-added to database)
13. Run php -l to verify syntax
Research: Find all GeneralUtility::makeInstance() calls in Classes/.
Decompose: One unit per class file.
Per unit:
1. Identify all makeInstance calls in the class
2. For each: add constructor parameter with type
3. Replace makeInstance calls with $this->propertyName
4. Add/update Services.yaml if needed
5. Use readonly promoted properties
6. Verify with php -l
Research: Scan Resources/Private/Templates/, Partials/, Layouts/.
Decompose: One unit per template directory or logical group.
Per unit:
1. Replace hardcoded strings with <f:translate> keys
2. Add missing XLIFF entries to locallang.xlf
3. Replace <a href="..."> with <f:link.page> or <f:link.typolink>
4. Replace <img> with <f:image>
5. Extract repeated blocks to Partials
6. Add accessibility attributes (alt, aria-label, role)
Research: Find all files containing old namespace/extension key.
Decompose: Group by file type (PHP, Fluid, YAML, TypoScript, SQL).
Per unit:
PHP files:
1. Replace namespace declarations
2. Replace use statements
3. Replace class references in strings (DI, TCA)
Fluid files:
1. Replace {namespace} declarations
2. Replace ViewHelper references
Configuration files:
1. Update composer.json autoload
2. Update ext_emconf.php
3. Update Services.yaml service names
4. Update TCA table prefixes
5. Update TypoScript paths (EXT:old → EXT:new)
Database:
1. Generate SQL rename migration
2. Update ext_tables.sql
Research: Scan ext_localconf.php and ext_tables.php for movable code.
Decompose: One unit per concern (TSconfig, TypoScript, icons, modules, plugins).
Per unit:
Page TSconfig:
1. Extract addPageTSConfig() calls
2. Create Configuration/page.tsconfig
3. Remove from ext_localconf.php
User TSconfig:
1. Extract addUserTSConfig() calls
2. Create Configuration/user.tsconfig
3. Remove from ext_localconf.php
Icons:
1. Extract icon registry calls
2. Move to Configuration/Icons.php (v14)
3. Remove from ext_localconf.php
Backend modules:
1. Extract registerModule() calls
2. Move to Configuration/Backend/Modules.php
3. Remove from ext_tables.php
Research: Check if Tests/ directory exists, find testable classes.
Decompose: One unit per test type.
Per unit:
Unit tests:
1. Create Tests/Unit/ structure
2. Generate test class per service/utility class
3. Add phpunit.xml.dist configuration
Functional tests:
1. Create Tests/Functional/ structure
2. Add fixture files
3. Generate test for repository/DataHandler usage
CI pipeline:
1. Create .github/workflows/ci.yml
2. Configure PHP matrix (8.2, 8.3, 8.4, 8.5)
3. Configure CI matrix (TYPO3 v14, PHP 8.2+)
Research: Scan Classes/ for PHP 8.4 migration candidates.
Decompose: One unit per class file.
Per unit:
1. Add property hooks where getter/setter pattern exists
2. Use asymmetric visibility (public private(set)) on DTOs
3. Replace array_search + if with array_find() **only after checking semantics** — `array_search()` returns a **key** for a given value; `array_find()` takes a **callback** and returns the first matching **value** (or null). Not drop-in replacements.
4. Replace array_filter + reset with array_find() where a callback-based “first match” is what you need
5. Replace `foreach` + conditional checks with `array_any()` / `array_all()` for value-based logic. These do **not** replace `array_key_exists()` (key-based checks).
6. Add #[\Deprecated] attribute to legacy methods
7. Run php -l to verify syntax
Research: Scan TCA, ext_tables.sql, and Fluid templates for classic content elements.
Decompose: One unit per content element / record type.
Per unit:
1. Create ContentBlocks/ContentElements/<name>/config.yaml
2. Map TCA columns to YAML fields
3. Move Fluid template to `ContentBlocks/ContentElements/<name>/templates/` (not `Source/`)
4. Align field definitions in `config.yaml` with TCA columns (no separate `EditorInterface.yaml` in Content Blocks)
5. Remove old TCA override file
6. Remove SQL from ext_tables.sql (columns become automatic)
7. Test rendering in frontend
Research: Find all hardcoded strings in Fluid, PHP flash messages, TCA labels.
Decompose: One unit per language file scope (frontend, backend, TCA).
Per unit:
1. Extract strings from templates/PHP
2. Generate XLIFF keys following convention
3. Add entries to Resources/Private/Language/locallang.xlf
4. Replace hardcoded strings with LLL: references
5. Create de.locallang.xlf with German translations (if applicable)
