Advanced Topics
This section covers advanced features and techniques in Grapa for power users and those extending the language or pushing its performance boundaries.
Meta-Programming and Execution Trees
- $OP Objects: Grapa supports direct manipulation of execution trees via
$OPobjects, enabling dynamic code generation, compilation, and execution at runtime. - Dynamic Evaluation: Use
$sys().eval()and$sys().compile()for advanced meta-programming patterns. - Reference: See Operator: Function and System Functions.
Custom Grammar and BNF
- Grammar Design: Grapa allows you to define and extend its grammar using BNF-like rules, enabling custom language features and DSLs.
- Reference: See Grammar Design and maintainer docs for implementation details.
Advanced System Functions
- System API: Advanced file, math, network, and threading functions are available for complex scripting and integration.
- Reference: See System Functions, File Operations, Math Functions, Thread Functions.
Performance Tuning and Parallelism
- Parallel Operations: Use
.map(),.filter(), and.reduce()with thread counts for parallel data processing. - Performance Optimization: For deeper performance tuning or engine internals, see the Deep Expert Implementation Overview.
Advanced Error Handling and Debugging
- Error Handling: Use
.iferr()for fallback, and advanced error patterns for robust scripts. - Debugging: Enable debug output and use advanced logging for troubleshooting.
