Module equivalence 

Equivalence checking utilities for comparing pattern-rs and gram-hs implementations

Using gramref CLI for Reference Outputs

The gramref CLI tool can be used to get reference outputs for comparison:

# Get reference output (value only, canonical format)
echo '(node1)' | gramref parse --format json --value-only --canonical

See gramref CLI Testing Guide for comprehensive usage examples and integration patterns.
