It's first edition is available free [online](http://www.lua.org/pil/contents.html) . The second edition was aimed at Lua 5.1, but is out of print. The third edition is still in print and available in paperback. It contains a lot more material and clearly identifies Lua 5.1 vs Lua 5.2 differences. **This third edition is widely available for purchase and probably the best value for money**. References of the format [PiL **n.m**] refer to section **n.m** in this edition. - The Espressif ESP8266 architecture is closed source, but the Espressif SDK itself is continually being updated so the best way to get the documentation for this is to [google Espressif IoT SDK Programming Guide](https://www.google.co.uk/search?q=Espressif+IoT+SDK+Programming+Guide) or to look at the Espressif [downloads forum](http://bbs.espressif.com/viewforum.php?f=5).
