Feature #93334
Updated by Benni Mack over 3 years ago
The syntax for "LLL:" has several drawbacks
* It references a path (also uses EXT:) which makes it hard to override
* Changing label files is more error prone
* The paths are unnecessary longer (EXT:my_ext/Resources/Private/Language/locallang_.xlf) and it is confusing for newcomers to understand both the folder structure and the naming (what does "locallang" mean? or "LLL"?).
For this reason, I propose a more "speakable" approach, since we talk about "labels" in this case (not to be confused with "translations" in content).
h3. What I want to address
* Making the syntax more consistent - find better solutions for "LLL:"
* Decouple the label identifier from the file name when addressing the label (making transitions from label names easier)
* Decouple the label identifier from an extension name + path
* Shorten the identifier massively for its usage
* Make it easier for people who CREATE such files to address.
h2. A new syntax proposal (totally up for discussion)
"label://vendor.package.namespace/resource-name/identifier-in-resource"
h3. Examples
Previously: LLL:EXT:core/Resources/Private/Language/Form/locallang_tabs.xlf:general
New: label://typo3.core/form.tabs/general
Previously: LLL:EXT:core/Resources/Private/Language/locallang_tca.xlf:pages.tabs.metadata
New: label://typo3.core/tca/pages.tabs.metadata
For a TER extension: LLL:EXT:news/Resources/Private/Language/locallang.xlf:news.title
New: label://georgringer.news/default/news.title
For other extensions: LLL:EXT:my_ext/Resources/Private/Language/locallang_modules.xlf:my-module
New: label://a-random-namespace/modules/my-module
h3. Usages
Fluid:
<pre>
<f:translate identifier="label://a-random-namespace/modules/my-module">Fallback string</f:translate>
</pre>
TypoScript:
<pre>
page.10 = TEXT
page.10.lang = label://my.site/resource/site-name
</pre>
PHP:
<pre>
$langService->label('label://my.site/resource/site-name')
</pre>
So, under the hood this is what happens:
* A "LabelProviderService" contains all available files registered within the system
* The existing "languageService" gets extended to translate the new "label://" syntax into the actual resource + identifier
* The existing "languageService->label()" is added to make the syntax more understandable, and falls back if no "LLL:" or "label://" syntax is used
* For existing extensions, existing labels can be provided automatically by checking for Resources/Private/Language/locallang.xlf and registering with the composer-name syntax automatically, making any registration for language file very easy and consistent via a ServiceProvider during build-time.
Manual registration would be possible as well
<pre>
LabelProvider->registerResource($pathToFile LabelProvider->registerResource($namespace = '...', $namespace = 'my.site', $resourceName = 'default'); 'default', $path);
</pre>
h2. Backwards-compatibility
* We still allow "LLL:" for a LONG time (just like we keep GeneralUtility::makeInstance() until a long time)
h2. Still up for discussion
* Overriding labels from extensions locally
* Dealing with translation server files
