Making Changes to the Tsugi PHP Library

The Tsugi PHP library is developed only in the main tsugi monorepo. The standalone tsugi-php repository is a read-only mirror used for Packagist distribution.

Canonical Rule

All changes to the Tsugi PHP library must be committed and pushed to
tsugi master before they are mirrored to tsugi-php.

Changes flow one way:

tsugi (master, lib/) → tsugi-php (master) → Packagist

Direct commits or pull requests to tsugi-php are not accepted and may be overwritten.

---

Step-by-Step Workflow

1. Work in the main Tsugi repository

Clone and work in the canonical repository:

git clone https://github.com/tsugiproject/tsugi.git
cd tsugi

Make all code changes only under the lib/ directory.

---

2. Commit and push to tsugi master

Before mirroring, changes must be committed and pushed to the canonical branch:

git status
git add lib/
git commit -m "Describe the change to the Tsugi PHP library"
git push origin master

Only committed changes are eligible to be mirrored.

---

3. Mirror lib/ to the tsugi-php repository

From the tsugi repository root, run the mirror script:

qa/mirror-tsugi-php.sh

This script:

1. Extracts the lib/ directory history
2. Reconstructs it as a standalone repository
3. Force-updates tsugi-php master using --force-with-lease

The result is an exact mirror of tsugi/lib.

---

4. Verify (optional)

After mirroring, you may verify that the change appears in the standalone repo:

git ls-remote https://github.com/tsugiproject/tsugi-php.git

or by browsing the repository on GitHub.

---

Important Notes

• The history in tsugi-php is a projection of the monorepo history and may differ from earlier standalone commits.
• Any commits made directly to tsugi-php may be replaced during the next mirror operation.
• All development discussion, issues, and pull requests belong in the main tsugi repository.

Running Unit Tests

The Tsugi PHP library includes a comprehensive test suite with 70+ test files covering Core, Util, UI, Crypt, and other components.

From the /tsugi/lib directory (monorepo)

When working in the main tsugi repository:

cd tsugi/lib
composer install  # Install dependencies if needed
composer test     # Run all tests

Or run PHPUnit directly:

cd tsugi/lib
./vendor/bin/phpunit --configuration phpunit.xml.dist

From the tsugi-php mirror repository root

When working in the standalone tsugi-php repository:

cd tsugi-php
composer install  # Install dependencies if needed
composer test     # Run all tests

Or run PHPUnit directly:

cd tsugi-php
./vendor/bin/phpunit --configuration phpunit.xml.dist

Running specific tests

To run a specific test file or directory:

# From lib/ or tsugi-php root
./vendor/bin/phpunit tests/Core/LaunchTest.php
./vendor/bin/phpunit tests/Util/

---

Summary

If you remember only one thing:

Commit and push to tsugi master first.
tsugi-php is generated from that state.
