# TantrixAuto/yantra

> A C++ LALR(1) parser generator with an integrated lexer, UTF-8 support, and built-in AST construction and walking. It turns a grammar into a parser as separate .hpp/.cpp files or a single self-contained file with main().

## Useful for

- Generate a parser for a custom language or DSL from a grammar
- Drop a generated parser into an existing C++ project as .hpp and .cpp
- Parse a character stream from a socket via the push-based lexer

## Why it’s here

- 8 stars so far today, about 15 expected by the end of the day. The usual pace is 0 per day, so that's 15× as much.
- Before this, the repository barely got any stars — about 0 per day.
- The spike has held for 2 days in a row — not a one-off blip.

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
