A Virtual Machine for the Pattern Matcher
A register-based virtual machine that compiles Wolfram Language patterns into bytecode for efficient, observable execution with explicit backtracking and comprehensive debugging support.
Compilation
— convert a pattern to a pure function for matching
— compile a pattern into executable bytecode
Pattern Matching
— execute a compiled pattern and return detailed match results
— test whether an expression matches a pattern
— apply pattern-based replacement rules to expressions
Pattern Matcher Objects
— compiled bytecode representation of a pattern
— virtual machine instance for executing bytecode
Bytecode Inspection
— display human-readable bytecode instructions
— retrieve metadata about compiled bytecode
Execution Control
— enable or disable step-by-step execution tracing
— check whether execution tracing is enabled
