Set license to Apache-2.0, and make REUSE compliant by RasmusRendal · Pull Request #66 · famedly/engineering-standards

RasmusRendal · 2026-08-06T08:48:57Z

The interesting part involves making sure that all our auto-generated
files have a REUSE header, or at least generate a .license file next to it.

Otherwise, we just set up a pre-commit hook that runs reuse lint-file on changed files.

I've tested it with rust-telemetry, and it works flawlessly there.

My favourite part of this PR is no longer having to add all files generated by ES to the REUSE.toml of all downstream projects.

PR Summary

Low Risk
Licensing and tooling-only: SPDX headers plus a REUSE pre-commit check. Downstream repos may see generated-file churn and a new lint failure mode, but runtime/security behavior is unchanged.

Overview
Declares Apache-2.0 for the repository and makes it REUSE-compliant so downstream projects no longer need to list engineering-standards–generated files in their own REUSE.toml.

Adds SPDX copyright/license headers across source and config, plus LICENSES/Apache-2.0.txt. New reuse.nix installs a reuse lint-file pre-commit hook and auto-emits .yml.license sidecars for generated GitHub workflows.

Introduces add-header.nix and uses it (plus similar header injection) so filegen output—treefmt.toml, .pre-commit-config.yaml, rustfmt.toml, .gitattributes, Dart analysis/dependency configs—ships with SPDX headers by default.

Will this be mandatory for all projects that use ES?

Yes, the PR in its current state would require all repositories which use Engineering Standards to be REUSE compliant.

The interesting part involves making sure that all our auto-generated files have a REUSE header, or at least generate a .license file next to it.

It simply runs reuse lint-file on changed files.
