Crate phpantom_lsp 

PHPantom — a lightweight PHP language server.

This crate is organised into the following modules:

• types — Data structures for extracted PHP information (classes, methods, functions, etc.)
• parser — PHP parsing and AST extraction using mago_syntax
• completion — Completion logic (target extraction, type resolution, item building, and the top-level completion request handler)
• composer — Composer autoload (PSR-4, classmap) parsing and class-to-file resolution
• server — The LSP LanguageServer trait implementation (thin wrapper that delegates to feature-specific modules)
• util — Utility helpers (position conversion, class lookup, logging)
• hover — Hover support (textDocument/hover). Resolves the symbol under the cursor and returns type information, method signatures, and docblock descriptions
• signature_help — Signature help (textDocument/signatureHelp). Shows parameter hints while typing function/method arguments, with active-parameter tracking
• definition — Go-to-definition support for classes, members, and functions
• inheritance — Base class inheritance resolution. Merges members from parent classes and traits into a unified ClassInfo
• virtual_members — Virtual member provider abstraction. Defines the VirtualMemberProvider trait and merge logic for members synthesized from @method/@property tags, @mixin classes, and framework-specific patterns (e.g. Laravel)
• resolution — Class and function lookup / name resolution (multi-phase: class_index → ast_map → classmap → PSR-4 → stubs)
• subject_extraction — Shared helpers for extracting the left-hand side of ->, ?->, and :: access operators (used by both completion and definition)
• docblock — PHPDoc block parsing, split into submodules:
  • docblock::tags — tag extraction (@return, @var, @property, @method, @mixin, @deprecated, @phpstan-assert, docblock text retrieval)
  • docblock::conditional — PHPStan conditional return type parsing
  • docblock::types — type cleaning utilities (clean_type, strip_nullable, is_scalar, split_type_token), PHPStan array shape parsing (parse_array_shape, extract_array_shape_value_type), and object shape parsing (parse_object_shape, extract_object_shape_property_type, is_object_shape)
