Crab
Crab is a memory-safe systems programming language and ahead-of-time compiler designed for high-performance software. It utilizes a type system based on strict ownership and borrowing rules to prevent memory access errors at compile time.
The toolchain includes an automated documentation generator that produces technical reference manuals and API guides by parsing structured source code annotations. It also features a dependency management tool to resolve external library graphs and ensure consistent project builds.
The project covers software build automation, static type checking, and multi-pass static analysis to verify constraints before generating machine-native binaries.
Features
- Memory-Safe Systems Languages - Enforces a memory-safe type system with strict ownership and borrowing rules to prevent access errors at compile time.
- Build and Dependency Management - Provides a comprehensive workflow for managing project lifecycles and external library dependencies.
- Library Version Resolution - Implements logic for calculating compatible library version sets to ensure consistent project builds.
- Build Dependency Management - Manages and resolves the external libraries and requirements necessary for consistent project builds.
- Ownership-Based Memory Management - Prevents memory errors through an ownership-based memory management model that avoids garbage collection overhead.
- Compiler Toolchains - Ships a complete compiler toolchain that transforms high-level source code into machine-native binaries.
- Ahead-Of-Time Compilers - Ships an ahead-of-time compiler that translates high-level source code into machine-native binaries for maximum performance.
- Source Code Compilers - Transforms high-level source code into optimized machine-native binaries via a specialized compiler.
- Ownership-Based Safety - Enables memory-safe software development by enforcing ownership and borrowing rules at compile time.
- Build Automation Tools - Automates the transformation of source code into executable binaries and manages necessary external libraries.
- Dependency Graph Resolution - Utilizes graph-based resolution to determine the correct build ordering and compatibility of external libraries.
- Static Type Checking - Verifies data types during the compilation process to catch errors before runtime.
- Static Analysis - Performs static analysis on source code to verify safety constraints without executing the program.
- Multi-Pass Analysis - Employs multi-pass static analysis to verify memory safety and type constraints before binary generation.
- Documentation Generators - Generates technical API guides and reference materials by extracting data from source code comments.
- Automated Generators - Produces technical reference manuals and API guides by automatically analyzing source code.
- Doc-Comment Extractors - Extracts structured information from source code documentation blocks to generate technical reference manuals.
- Dependency Management Tools - Includes a tool for resolving external library graphs and ensuring consistent project builds.
- API Documentation Generators - Provides automated API documentation generation by parsing structured annotations directly from the source code.
- Automated API Documentation - Provides automated generation of technical specifications and documentation directly from source code definitions.
