lib.rs

1//! The `powershell` 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-powershell 0.26.3
5//! (<https://github.com/airbus-cert/tree-sitter-powershell>, tag `v0.26.3`). Generated: do
6//! not edit by hand, except the scanner (`scanner.rs`).
