# Unified linting script for yaze
|

# Wraps clang-format and clang-tidy with project-specific configuration

#
|
||||
# Usage:
|
||||
# scripts/lint.sh [check|fix] [files...]
|
||||
#
|
||||
# check (default) - Check for issues without modifying files
|
||||
# fix - Automatically fix formatting and some tidy issues
|
||||
# files... - Optional list of files to process (defaults to all source files)
