[Bug] Cannot override language files

[bedoz]

Bug report

What I did

I tried to publish language files on laravel 12

Context to replicate the bug - Backpack, Laravel, PHP, DB version

PHP VERSION:

8.4.11

PHP EXTENSIONS:

Core, bcmath, calendar, ctype, date, hash, iconv, json, pcre, random, readline, Reflection, SPL, session, tokenizer, zlib, libxml, dom, filter, standard, PDO, openssl, mysqlnd, SimpleXML, xml, xmlreader, xmlwriter, curl, ftp, fileinfo, gd, intl, mbstring, exif, mysqli, Phar, pdo_mysql, pdo_sqlite, soap, sodium, sqlite3, xsl, zip

LARAVEL VERSION:

12.21.0.0

BACKPACK PACKAGE VERSIONS:

backpack/activity-log: 2.0.7
backpack/backupmanager: v5.0.6
backpack/basset: 1.3.9
backpack/crud: 6.8.4
backpack/generators: v4.0.7
backpack/language-switcher: 2.0.1
backpack/logmanager: 5.0.3
backpack/permissionmanager: 7.2.1
backpack/pro: 2.2.35
backpack/settings: 3.1.2
backpack/theme-tabler: 1.2.18

I think that can be useful to upgrade this package to laravel 12 language management.
I solved adding this into my AppServiceProvider.php file into boot function

$this->loadTranslationsFrom(app()->langPath(), 'backpack.activity-log');

Based on the information in the knowledge sources, Backpack uses Laravel's default localization system for language files. To override Backpack's language files, you should publish them using:

php artisan vendor:publish --provider="Backpack\CRUD\BackpackServiceProvider" --tag="lang"

This will copy all language files to resources/lang/vendor/backpack, where you can customize them. Any strings you place here will override the package defaults. If you only need to override a few strings, you can create the relevant files and keys in this directory without publishing everything. If you publish all languages, it's recommended to delete the ones you don't customize to ease future upgrades.

However, if you are experiencing issues with overriding language files in Laravel 12, the knowledge sources do not provide explicit information about changes required for Laravel 12's language management or any incompatibility with Backpack 6.x. There is a suggestion that Backpack's language publishing and overriding should work as described above, but if Laravel 12 introduced breaking changes to language file handling, this is not covered in the provided sources.

If you are unable to override language files as expected, it may be due to changes in Laravel 12 that are not yet documented in Backpack's official documentation or issues. The best course of action would be to check for updates in Backpack's documentation or open an issue with detailed replication steps for the maintainers to investigate.

For reference on how Backpack expects language overrides to work, see the official documentation: Customize the translated strings (aka overwrite the language files).

If you need to translate Laravel's own validation or internal messages, Backpack recommends using the Laravel Lang package, as Backpack does not provide those translations itself.

In summary:

• Overriding Backpack language files should work by publishing them to resources/lang/vendor/backpack.
• There is no explicit information in the knowledge sources about required changes for Laravel 12.
• If you encounter issues, consider reporting them to the Backpack team with details.

If you need more specific guidance for Laravel 12, the knowledge sources do not contain enough information to provide a confident answer.
