Parser (src/parser/)

Status: Partially Implemented

Feature Specification Implementation Status Notes
Program Structure grammar.md ✅ Implemented parse_program handles top-level statements.
Package Declaration (vibe) grammar.md ✅ Implemented parse_package_statement correctly parses vibe PackageName ;.
Imports (yeet) grammar.md ❌ Not Implemented ImportStatement AST node exists in ast/statements/declarations.rs, but no parsing logic found for yeet "path" or yeet (...). Token::Yeet not handled in parse_statement.
Variable Declaration (sus) grammar.md 🟡 Needs Verification Handles sus Ident [Type] = Expr ;. Grouped declarations (sus (...)) not implemented.
Constant Declaration (facts) grammar.md 🟡 Needs Verification Handles facts Ident = Expr ;. Grouped declarations (facts (...)) not implemented.
Type Declaration (be_like) grammar.md 🟡 Needs Verification Structs (be_like Name squad {}) implemented. General type aliases (be_like NewType OldType) not implemented.
Function Declaration (slay) grammar.md ✅ Implemented Handles slay Name(Params) [Return] { Body }.
Method Declaration grammar.md ❌ Not Implemented parse_function_statement does not handle receiver parameters of the form (recv Type). AST structure exists for MethodSignature in interfaces but not for concrete type methods.
Return Statement (yolo) grammar.md 🟡 Needs Verification Handles yolo [Expr] ;. Multiple return values (yolo expr1, expr2) not implemented.
If Statement (lowkey) grammar.md ✅ Implemented Handles lowkey [Init;] Cond { Block } [highkey Else].
For Statement (bestie) grammar.md ✅ Implemented Handles standard loops (for ;;, for cond, for init;cond;post). Range clause (flex) implemented via parse_range_for_statement.

Short Var Decl (:=) grammar.md 🟡 Needs Verification parse_decl_assign_statement exists but creates incorrect AST node (ExpressionStatement instead of proper DeclAssignStatement). Multiple assignment (x, y := 1, 2) not implemented.
Inc/Dec Statements (++/--) grammar.md ✅ Implemented Handled via expression parsing.

    • hash_drip: Hash functions package defined in specs/stdlib/hash_drip.md with partial implementation in src/stdlib/cryptz.rs:
      • The cryptz.rs implementation provides basic cryptographic hash functions (md5sum, sha1sum, sha256sum), HMAC functionality, and random bytes generation
      • However, it lacks the comprehensive interface-based approach defined in the hash_drip specification:
        • Missing the Hash interface and HashFunc type for creating new hash instances
        • Missing implementations for many hash algorithms specified (CRC32, FNV, Blake2b, Blake2s, SHA3)

      • The interface difference makes it difficult to extend the system with custom hash implementations
      • This partial implementation limits the cryptographic capabilities of the CURSED language

Key Implementation Gaps

Based on detailed investigation, these are the critical gaps that should be addressed:

  1. Concurrency Features:

    • Testing Framework:
      • No implementation of the comprehensive test_vibes package defined in specs/stdlib/test_vibes.md.
      • The specification includes VibeTest and VibeBench structs, assertion functions, test fixtures, table-driven tests, and mocking capabilities.
      • While there is a quick_test.rs module providing property-based testing (like QuickCheck), it doesn't implement the full testing framework specified in test_vibes.md.
      • Missing important features like test fixtures, assertion functions, and mocking capabilities that are essential for proper testing.
    • Embedding System:

      • No implementation of the core I/O interfaces defined in specs/stdlib/yeet_io.md.
      • Missing the Yoink (Reader) and Yeeter (Writer) interfaces that underpin all I/O operations.
      • Missing utility functions like YeetAll (Copy) and LimitedYoink (LimitReader).
      • This is a critical gap as many other packages depend on these interfaces for proper I/O operations.
    • Buffered I/O:
      • No implementation of the buffered I/O functionality defined in specs/stdlib/slay_io.md.
      • Missing SlayReader and SlayWriter implementations for efficient buffered I/O.

      • The missing implementation means there's no proper support for complex number operations in the language
    • Atomic Operations:
      • The atomic_drip package specified in specs/stdlib/atomic_drip.md has no implementation in the codebase. This package is critical for thread-safe operations including:
        • Atomic versions of basic types (Int32, Int64, Bool, etc.)
        • Atomic operations (Load, Store, CompareAndSwap, etc.)
        • Memory ordering semantics

      • This gap significantly limits the concurrency capabilities of the language
    • Binary Data Handling:
      • No implementation of the binary_drip package defined in specs/stdlib/binary_drip.md.
      • The specification outlines comprehensive binary data encoding/decoding including:
        • Reading and writing binary values with different byte orders
        • Encoding and decoding various data types (integers, floats, strings)
        • Stream-based binary processing
        • Bit-level encoding and decoding capabilities
      • Missing this functionality makes it difficult to work with binary data formats and network protocols

        • Non-cryptographic hashes (CRC32, FNV)
        • HMAC support for keyed hashing
        • Interfaces for custom hash implementations
      • This gap limits cryptographic capabilities and data integrity verification in CURSED

        • Support for modern TLS versions (1.2, 1.3) and secure cipher suites
        • Session caching and resumption
        • Advanced features like certificate rotation, ALPN, and Certificate Transparency
      • The missing implementation means there's no secure communication capability in the standard library
      • Without TLS support, secure connections for HTTP (HTTPS), email protocols, and other network communications cannot be established
      • This is a significant gap for any production-ready language as secure communication is a fundamental requirement
    • Process Management:
      • No implementation of the exec_vibez package defined in specs/stdlib/exec_vibez.md.
      • The specification outlines functionality for:
        • Executing external commands and processes
        • Capturing process output and providing input
        • Managing process lifecycle (start, wait, signal, kill)
        • Setting environment variables and working directories for processes
      • Without this, CURSED programs cannot easily interact with external programs or the operating system
      • This limits the language's capability for scripting, automation, and system integration

While the AST structure for import statements exists in ast/statements/declarations.rs, the parser does not implement the handling of Token::Yeet. The src/codegen/llvm/import_statement.rs file contains a stub implementation for import statement compilation, but it lacks actual functionality.

Specifics Missing:

  • Parser implementation for yeet statements in parse_statement function
  • Support for both simple imports (yeet "package") and grouped imports (yeet (...))
  • Runtime support for resolving package paths and loading imported modules
  • Namespace management for imported symbols

2. Type Aliases (be_like NewType OldType)

While the grammar in specs/grammar.md specifies support for type aliases using the be_like keyword, the current implementation only handles the struct definition form (be_like Type squad {}). The parser handles BeLikeExpression as a struct instantiation with fields, but lacks support for general type aliases.

Specifics Missing:

  • AST node for type alias declarations
  • Parser logic to differentiate between be_like Type squad {} (struct declaration) and be_like NewType OldType (type alias)
  • Type checker handling for aliases
  • Code generation support for aliased types

3. Method Declarations with Receivers

The AST for function declarations (FunctionStatement) does not include support for method receivers. There is no parser implementation to handle method declarations with the syntax slay (r Receiver) method().

Specifics Missing:

  • Support for method receivers in FunctionStatement AST or a separate MethodStatement AST node
  • Parser implementation to recognize method declaration syntax
  • Symbol table updates to correctly track receiver types
  • Code generation for methods with receiver parameters

4. Select Statement for Concurrency

The select statement, critical for working with multiple channels in concurrent programming, is entirely missing from the implementation despite being documented in the concurrency specification.

Specifics Missing:

  • AST node for select statements and select cases
  • Parser implementation for select statement syntax
  • Code generation for select operations
  • Integration with the channel runtime implementation

6. Advanced Control Flow

Labeled break and continue statements (ghosted Label and simp Label) are documented in the specifications but not implemented in the codebase.

Specifics Missing:

  • The AST for BreakStatement and ContinueStatement doesn't include fields for labels
  • The parser doesn't handle labeled forms of break and continue
  • Code generation doesn't support jumping to labeled loop statements

7. Type Switch

The type switch pattern (vibe_check x.(type)) for handling interface types is not fully implemented.

Specifics Missing:

  • Parser doesn't handle the special syntax for type switches
  • AST structures for type case clauses are missing
  • No code generation support for type switching

8. Multiple Assignment and Return Values

While there are references in the test files to using syntax for multiple return values and multiple assignments (as seen in tests/interface_type_conversion_test.rs), the actual implementation appears incomplete:

Specifics Missing:

  • The ReturnStatement AST node doesn't support returning multiple expressions
  • The parser has no handling for comma-separated expressions in return statements
  • The assignment implementation in codegen/llvm/assignment.rs only handles single value assignments
  • No proper tuple representation for multiple return values
  • No destructuring mechanics for multiple assignments like a, b = func()

This limitation affects several important language patterns:

  • Error handling with the common value, err = function() pattern
  • Pattern matching and destructuring
  • Working with functions that return multiple values
  • Parallel assignments

This feature gap is particularly noteworthy since the test code references tuples and multiple returns, but the implementation doesn't fully support them throughout the compiler pipeline.

These gaps in implementation represent significant hurdles for completing the CURSED language implementation, particularly for supporting proper package management, concurrency, object-oriented programming patterns, and idiomatic error handling.

9. Interface Implementation and Reflection

While the interface implementation (collab declarations) appears more complete than other areas of the language, there are still gaps:

Interface Features Implemented:

  • AST structures for interface declarations (CollabStatement)
  • Support for method signatures within interfaces
  • Type checker for verifying implementations
  • Runtime type information for dynamic dispatch
  • Interface value creation with concrete types
  • Type assertions from interface types to concrete types

Interface Features Missing or Incomplete:

  • Method declarations with receivers (as noted earlier)
  • Type switches for handling different concrete types
  • Proper error messages for interface implementation mismatches
  • Complete reflection API as specified in specs/stdlib/lookin_glass.md

The reflection package (reflectz) has a partial implementation in src/stdlib/reflectz.rs but lacks several features described in the spec:

  • Many of the Type interface methods are missing
  • Full support for struct field inspection is incomplete
  • Method introspection capabilities are limited
  • Advanced features like interface inspection are not implemented

These gaps are particularly important as interfaces and reflection are key to building flexible, maintainable code with proper abstraction boundaries.

10. Error Reporting and Diagnostics

The error handling system in CURSED is partially implemented with several components:

Error Handling Features Implemented:

  • Basic error types for different compilation stages in src/error.rs
  • Enhanced error types with context in src/error_enhanced.rs
  • Error reporting utilities in src/benchmark/reporters.rs
  • Error registry and handling in the standard library (src/stdlib/error_drip.rs)
  • LLVM-specific errors in src/codegen/llvm/errors.rs

Error Handling Features Missing or Incomplete:

  • Integration between the different error systems
  • Consistent error wrapping throughout the compiler
  • Source location tracking for many error types
  • User-friendly error messages with code snippets and suggestions
  • Error recovery capabilities during parsing and type checking
  • Integration with IDE tooling for interactive error reporting
  • Standardized error codes and documentation

A comprehensive error system is crucial for language adoption, as it significantly impacts the developer experience. Current limitations in error reporting make debugging CURSED programs more difficult than necessary, especially for complex features like generics, interfaces, and concurrency.

11. Generics and Parametric Polymorphism

The generics system in CURSED appears to be partially implemented with several key components:

Generics Features Implemented:

  • AST structures for type parameters and constraints (src/ast/expressions/generics.rs, src/ast/expressions/constraint.rs)
  • Support for generic functions and their type parameters in the AST
  • Generic instantiation mechanism (src/core/generic_instantiation.rs)
  • Some type checking for generic constraints
  • Code for monomorphization in src/codegen/monomorphization.rs and src/codegen/llvm/enhanced_monomorphization.rs
  • Support for parsing generic function calls with type arguments

Generics Features Missing or Incomplete:

  • Complete integration between parser, type checker, and code generator for generics
  • Support for more complex generic constraint systems (multiple constraints, composite constraints)
  • Efficient specialization for common generic types
  • Support for partial specialization of generic types
  • Type inference for generic function calls (allowing omission of type arguments)
  • Complete validation of generic constraint satisfaction
  • Proper error messages for constraint violations

While the foundation for generics exists, the implementation appears to be somewhat fragmented, with different components working in isolation rather than as a cohesive system. This is particularly evident in the multiple implementations of similar functionality in different modules (e.g., monomorphization.rs vs. enhanced_monomorphization.rs).

The constraint checking system exists but doesn't appear to be fully integrated with the compiler pipeline, which would limit the expressiveness and safety guarantees that generics should provide.

These gaps in implementation represent significant hurdles for completing the CURSED language implementation, particularly for supporting proper package management, concurrency, object-oriented programming patterns, and idiomatic error handling.

12. I/O Interfaces and Advanced Features

The dropz implementation is missing several key components specified in the documentation:

Specifics Missing:

  • Core interfaces (Reader, Writer, Closer, ReadWriter, etc.) are not implemented.
  • No implementation of StringBuilder for efficient string construction.
  • Missing advanced utilities: ReadAll, MultiReader, MultiWriter, TeeReader, LimitReader.
  • No buffered I/O operations (the bufio functionality mentioned in docs).
  • Custom Readers and Writers support (ability to extend I/O interfaces) is not implemented.
  • The implementation focuses only on file-based operations rather than providing a complete I/O interface system.

These gaps in implementation represent significant hurdles for completing the CURSED language implementation, particularly for supporting proper package management, concurrency, object-oriented programming patterns, and idiomatic error handling.

  • I/O Interfaces and Advanced Features: The dropz implementation is missing several key components specified in the documentation:

    • Missing Core Interfaces: According to the web documentation and references in other packages, dropz should implement core interfaces like Reader, Writer, Closer, ReadWriter, etc., but the current implementation only provides standalone file operation functions without any interface hierarchy.
    • No Interface Implementation: The current implementation does not provide the interface-based abstraction that would allow custom readers and writers to be implemented by users.
    • Missing Advanced Utilities: Utilities like ReadAll, MultiReader, MultiWriter, TeeReader, LimitReader mentioned in references to the package are not implemented.
    • Limited to File Operations: The current implementation focuses exclusively on file-based operations rather than providing a complete I/O interface system that could work with any data source or sink.
    • No Integration with yeet_io: The dropz package should implement or use the interfaces defined in yeet_io (Yoink as Reader and Yeeter as Writer), but since yeet_io is not implemented, this integration is missing.

    This limitation relates directly to the missing yeet_io package, which would provide the foundational interfaces (Yoink as Reader and Yeeter as Writer) that dropz should build upon. Without these core interfaces, the entire I/O system lacks the composability and flexibility that would allow stream-based operations and custom I/O implementations.
