Release 1.2.0

Mozart 1.2.0 is a major feature release. 🎉 The headline: Mozart now works with zero configuration — just run mozart compose and it handles the rest. This release also adds global-scope constant and function prefixing and automatic autoloader generation.

New features

• Zero configuration — Running mozart compose is now the only opt-in required. All six settings have sensible defaults, inferred from your project's composer.json. Existing extra.mozart blocks continue to work unchanged. A new mozart config command lets you inspect the resolved configuration and where each value came from. #316
• Autoloader generation — Mozart now generates a Composer-compatible autoloader file covering PSR-4, classmap, and files entries for all processed dependencies. This is enabled by default (generate_autoloader: true) and replaces the need to manually configure your project's composer.json autoload section. See usage docs. #315
• Global-scope constant prefixing — Constants declared with const or define() at global scope are now prefixed with constant_prefix (defaults to an uppercased version of classmap_prefix). References via constant(), defined(), and bare constant fetches are updated throughout the codebase. #308
• Global-scope function prefixing — Functions declared at global scope are now prefixed with functions_prefix (defaults to a lowercased version of classmap_prefix). References via function_exists() and direct function calls are updated accordingly. #308
• PHP built-in symbol protection — Mozart ships a database of PHP built-in symbols (PHP 7.4–8.5) and skips them during renaming. Polyfill packages like symfony/polyfill-php80 are no longer broken by having their declarations prefixed. #306

Improvements

• Namespaced define() calls routed correctly — define() inside a namespace block is now handled by the namespace replacer instead of being incorrectly prefixed with constant_prefix. #353
• Files autoloader basename collision — Global-scope files with the same basename but in different directories are no longer flattened to the same target path. #351
• NameVisitor routes by symbol type — Class, constant, and function references are now matched against their respective maps, preventing cross-type collisions. #363
• Case-insensitive symbol lookups — Class and function name matching is now case-insensitive (as PHP itself is), while constant matching remains case-sensitive. #314
• Parent replacer propagation for files autoloaders — Namespaced files autoloader entries in parent packages now receive constant and function renames from child packages. #365, #367
• Generated autoloader hardening — Fixed file identifier collisions, Windows path separators in $baseDir, and absolute classmap paths. #362
• Boolean config values detected correctly — delete_vendor_directories: false and generate_autoloader: false are now properly distinguished from "not set" when reporting config sources. #323
• Parent replacer early return — Fixed replaceParentPackage() exiting after the first autoloader combination instead of processing all of them. #288
• Enum declaration support — Enums are now handled in both the declaration visitor and classmap mode. #290, #313
• Diamond dependency reprocessing — Added a visited-set to replacePackages() to prevent processing the same package twice. #292
• Typed exceptions — All bare exceptions replaced with MozartException subtypes; error output uses writeln() instead of write(). #294
• FilesHandler exception wrapping — All Flysystem exceptions are now wrapped in FileOperationException. #296
• Windows directory separator — Fixed PSR-4 path flattening breaking on Windows backslashes. #310

Forward ported bug fixes

These bug fixes have been released earlier today in versions 1.1.4 and 1.0.10 as well:

• PHPDoc FQCN prefixing hardened — Fully-qualified class names in PHPDoc annotations (@param, @return, @var, @throws, etc.) logic reworked and are now properly rewritten to use the prefixed namespace. #360
• Shared vendor dependencies preserved during cleanup — Vendor directories required by non-processed installed packages are no longer deleted. #357

Infrastructure

• PHP minimum raised to 8.2 (from 8.1) #368
• Upgraded to PHPUnit 11, PHPStan 2.x, Symfony 7.x, php-parser 5.x (only) #368
• Docker images updated to Composer 2.9.5 and Xdebug 3.5.1 #368
• GitHub Actions bumped to latest major versions #368

Upgrade notes

• PHP 8.2 required — Mozart 1.2.0 requires PHP 8.2 or higher. The resulting bundled files can still target any PHP version.
• Autoloader generation is on by default — If you already manually configure autoloading in your project's composer.json for Mozart-processed dependencies, have your code include the newly created autoload.php to benefit from this new feature. Or alternatively, set generate_autoloader to false in your extra.mozart block to keep your existing setup. See the configuration docs.
• New prefixes are applied automatically — constant_prefix and functions_prefix are derived from classmap_prefix by default. If your dependencies declare global-scope constants or functions, these will now be prefixed. Set either to an empty string in extra.mozart to disable.

Documentation

Full documentation for all features is available in docs/:

• Configuration reference — all settings, defaults, and inference chain
• Usage guide — autoloader generation and Composer integration
• Replace pipeline — how AST-based replacement works
• Autoloaders — PSR-4, PSR-0, classmap, and files autoloader handling
