YARA-X 1.10.0: Using “yr fix warnings” to auto-correct brittle rules

YARA-X 1.10.0 adds a new subcommand that can automatically apply suggested fixes for certain compiler warnings. The command is invoked as yr fix warnings, and one common transformation replaces ambiguous 0 of (...) conditions with explicit none of (...). The tool edits your rule files in place, so use version control or work on copies first. (github.com)

Overview

YARA-X is a Rust rewrite of YARA with a modern CLI named yr. It targets high compatibility with existing rules while improving performance, safety, and developer ergonomics. (github.com)
