tree_sitter_bash/
lib.rs

1//! The `bash` 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-bash 0.25.1 (<https://github.com/tree-sitter/tree-sitter-bash>,
5//! tag `v0.25.1`). Generated: do not edit by hand, except the scanner (`scanner.rs`).
