tree_sitter_php_only/
lib.rs

1//! The `php_only` tree-sitter grammar for the ported runtime: its tables (decoded from
2//! `tables.bin`) and lexer (`lex.rs`), converted from the grammar's `src/parser.c`.
3//!
4//! Upstream: tree-sitter-php 0.25.1 (<https://github.com/tree-sitter/tree-sitter-php>, tag
5//! `v0.25.1`). Generated: do not edit by hand (the scanner is a copy of php's
6//! `scanner.rs`).
