[ ![Tombstone Youtube Video](https://camo.githubusercontent.com/34da522aec1933a7f65c0153f758039e433e2845c301a458e94329194ad9195d/68747470733a2f2f692e7974696d672e636f6d2f76692f323955587a6651574f68512f6d617872657364656661756c742e6a7067)](https://www.youtube.com/watch?v=29UXzfQWOhQ)When you want to identify and clean-up dead code in a project, static code analysis tools are the weapon of choice. But these tools have some limitations, especially in a dynamic language like PHP: - They can only tell you, if a piece of code is referenced, not if it's actually used - They cannot resolve dynamic or generated call paths Tombstones provide a way to track if a piece of code is actually invoked. **They are executable markers in your code**, that you can place where you suspect dead code. Then, you collect tombstone invocations on production. After a while, the logs will tell you, which tombstones are dead and which ones aren't (the so called "vampires"). Installation ------------ [](#installation) The library consists of multiple components, that need to be installed and configured independently: Read [how to install `scheb/tombstone-logger`](doc/logger/installation.md) for placing and logging tombstones in your code. Read [how to install `scheb/tombstone-analyzer`](doc/analyzer/installation.md), which takes log data from `scheb/tombstone-logger` to generate reports in various formats. For example an HTML report: [![Dashboard view](doc/analyzer/dashboard-small.png)](doc/analyzer/dashboard.png) [![Code view](doc/analyzer/code-small.png)](doc/analyzer/code.png) Security -------- [](#security) For information about the security policy and know security issues, see [SECURITY.md](SECURITY.md). Contributing ------------ [](#contributing) Want to contribute to this project? See [CONTRIBUTING.md](CONTRIBUTING.md). License ------- [](#license) This software is available under the [MIT license](LICENSE). Acknowledgments --------------- [](#acknowledgments) The library is heavily inspired by [Nestoria.com's implementation](http://devblog.nestoria.com/post/115930183873/tombstones-for-dead-code)of the tombstone concept. Thanks to [Jordi Boggiano](https://github.com/Seldaek) for creating [Monolog](https://github.com/Seldaek/monolog), from where I lend the handler/formatter concept. The tombstone graphic is based on a licensed illustration by "lemonadeserenade". Support Me ---------- [](#support-me) I'm developing this library since 2015. I love to hear from people using it, giving me the motivation to keep working on my open source projects. If you want to let me know you're finding it useful, please consider giving it a star ⭐ on GitHub. If you love my work and want to say thank you, you can help me out for a beer 🍻️ [via PayPal](https://paypal.me/ChristianScheb). ### Health Score 63 — FairBetter than 99% of packages Maintenance82 Actively maintained with recent releases Popularity56 Moderate usage in the ecosystem Community29 Small or concentrated contributor base Maturity70 Established project with proven stability Bus Factor1 Top contributor holds 93.9% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
