Lua Packaged by IOanyT Innovations - RHEL 8

OVERVIEW:

It was designed from the beginning to be software that can be integrated with the code written in C and other conventional languages. This integration brings many benefits. It does not try to do what C can already do but aims at offering what C is not good at: a good distance from the hardware, dynamic structures, no redundancies, ease of testing and debugging. For this, Lua has a safe environment, automatic memory management, and good facilities for handling strings and other kinds of data with dynamic size.

Features

Lua provides a set of unique features that makes it distinct from other languages. These include −

• Extensible

• Simple

• Efficient

• Portable

• Free and open
