I love watching metrics over time and at the same time I'd like to follow where the Magento 2 code is emerging. This is why I used phploc to collect all kinds of metrics for every public snapshot of the Magento 2 code on GitHub.
For the following statistics only the code in following directories is being looked at:
- lib/Mage (if present)
- lib/Magento (if present)
- lib/Varien (if present)
If you're interested in the raw data check out this spreadsheet.
(Status: everything up until 188.8.131.52-dev77)
