lm-format-enforcer README: JSON Schema / JSON mode / regex enforcement via character-level parsers feeding a prefix-allowed-tokens function, with batched generation and beam search support. Documents vLLM server integration through `--guided-decoding-backend lm-format-enforcer`. The README's own comparison table shows it losing the field to guidance and outlines on several capabilities, and to xgrammar since xgrammar became the vLLM default.
