I've been experimenting a little lately with embedding Lua and Python in an app to provide better scripting features.. OSNews points today to a nice intro to what the Lua language is all about:

Lua is a scripting language developed at the Pontifical Catholic University of Rio de Janeiro (PUC-Rio) that has come to be the leading scripting language for video games worldwide.3,7 It is also used extensively in embedded devices like set-top boxes and TVs and in other applications like Adobe Photoshop Lightroom and Wikipedia.14 Its first version was released in 1993. The current version, Lua 5.3, was released in 2015.

The lack of built-in complex constructions and minimalist standard libraries (for portability and small size) make Lua a language that is not as good as other scripting languages for writing "quick-and-dirty" programs. Many programs in Lua need an initial phase for programmers to set up the language, as a minimal infrastructure for object-oriented programming. More often than not, Lua is embedded in a host application. Embedding demands planning and the set-up of the language is typically integrated with its embedding. Lua's economy of concepts demands from programmers a deeper understanding of what they are doing, as most constructions are explicit in the code. This explicitness also allows such deeper understanding. We trust this is a blessing, not a curse.
