Hi folks, Since we can't just use the channel info feature from PEAR, Pyrus installer without installers, and it's hard to reuse. To implements Onion packager, I wrote a lightweight PEAR channel client library (PEARX) , without Installer dependency (like PEAR or Pyrus). PEARX - A lightweight non-installer-dependent PEAR channel library. https://github.com/c9s/PEARX It's standalone, fast and cacheable. Enjoy! Best Regards, Cornelius (c9s)
