Gitattributes

.gitattributes Export-Ignore Audit

Ensure the WordPress.org release archive (git archive output) contains only runtime files. Dev tooling, tests, CI, and repo meta must be export-ignored.

Why This Matters

The WordPress.org zip is built via git archive. Anything without export-ignore ends up on every user's site, bloating the install and shipping dev-only code. Equally bad: stale export-ignore entries for files that no longer exist look tidy but protect nothing.

Quick Audit (one command)

# Entries in the release archive at the repository root
git archive --format=tar HEAD | tar -t | awk -F/ '{print $1}' | sort -u

# Same, but uses the working-tree .gitattributes (use while iterating on edits)
git archive --worktree-attributes --format=tar HEAD | tar -t | awk -F/ '{print $1}' | sort -u

git archive HEAD reads .gitattributes from the commit, so uncommitted fixes won't show up. Use --worktree-attributes to preview a pending change before committing.

The output should contain ONLY runtime artifacts. For this plugin that's:

LICENSE, readme.txt, activitypub.php, assets, build, includes, integration, patterns, templates.

Anything else in the list is a gap — add an export-ignore rule.

Cross-Check Tracked vs Ignored

# Top-level tracked entries
git ls-tree --name-only HEAD | sort > /tmp/tracked.txt

# Entries referenced in .gitattributes
grep export-ignore .gitattributes | awk '{print $1}' | sed 's|^/||; s|/$||' | sort > /tmp/ignored.txt

# Stale entries (in .gitattributes but no longer tracked)
comm -23 /tmp/ignored.txt /tmp/tracked.txt

Stale entries aren't dangerous, but they rot and mislead future readers. Delete them.

What Belongs in Each Bucket

| Category | Examples | Rule |

|----------|----------|------|

| Runtime PHP | activitypub.php, includes/, integration/ | keep |

| Runtime assets | assets/, build/, patterns/, templates/ | keep |

| WordPress.org meta | readme.txt, LICENSE | keep |

| Dev dotfiles | .editorconfig, .prettierrc.js, .stylelintrc.json, eslint.config.cjs, .wp-env.json | export-ignore |

| Repo meta | .github/, .githooks/, .gitignore, .gitattributes, .wordpress-org/ | export-ignore |

| Agent/AI tooling | .agents/, .claude/, AGENTS.md, CLAUDE.md | export-ignore |

| Build & package configs | package.json, package-lock.json, composer.json, webpack.config.js, tsconfig.json, jest.config.js, jest.setup.js | export-ignore |

| QA configs | phpcs.xml, phpunit.xml.dist | export-ignore |

| Source (pre-build) | src/ | export-ignore (shipping build/ instead) |

| Tests | tests/ | export-ignore |

| Docs for contributors | docs/, snippets/, CHANGELOG.md, CODE_OF_CONDUCT.md, CONTRIBUTING.md, FEDERATION.md, README.md, SECURITY.md | export-ignore |

| Scripts | bin/, local/ | export-ignore |

When to Run This Audit

• Before tagging a release.
• After adding or renaming any top-level file, dotfile, or config.
• After adopting a new dev tool (lint, test runner, bundler).
• When a linter flat-config migration renames files (e.g. .eslintrc.js → eslint.config.cjs).

Writing Rules

• Use a leading / to anchor to the repo root: /phpcs.xml, not phpcs.xml.
• Use a trailing / for directories: /tests/.
• Keep grouping comments tidy (dotfiles, build configs, source/tests, docs, linguist).

Linguist Attributes (bonus)

Also used in .gitattributes to shape GitHub's language stats:

• /build/** linguist-generated — hides machine-built output.
• /docs/** linguist-documentation — keeps docs out of the language bar.
• /package-lock.json linguist-generated — hides lockfile churn.

These don't affect the archive, but live in the same file, so keep them current too.

Red Flags

• Release zip is larger than expected → something new is leaking in.
• New dev dependency added, .gitattributes untouched → likely a gap.
• Lint tool migrated to a new config filename → old entry is stale, new file is leaking.
• Top-level file renamed → old export-ignore is dead weight, new one is missing.
