Overview

Concrete tool for automatically adding or updating NVIDIA copyright headers across all source files in the Triton repository.

Description

add_copyright.py walks the repository file tree and manages NVIDIA copyright headers. It identifies file types by extension (C/C++, Python, shell, CMake, Dockerfile), updates existing copyright year ranges to include the current year, and inserts new copyright headers with file-type-specific comment prefixes. It handles shebang-aware insertion for script files and includes built-in pytest tests for validation.

Usage

Run as a developer tool when preparing commits to ensure all modified or new files have proper copyright headers. Can be used as a pre-commit hook or CI check.
