RiscLua version history
Lua evolved from a data-entry language devised for PETROBRAS, the Brazilian oil company in the early 1990s. Its keynote has been simplicity. The current version is Lua 5.1. The term refers to a C library and to a programming language which the library implements. Both aspects have been designed for portability, extendibility and embeddability

RiscLua is a dialect of Lua for RISC OS, which can be downloaded from this site. The sources can also be downloaded.

It differs from standard Lua in its treatment of arithmetic, and has built-in libraries giving access to software interrupts. In consequence it can be used for writing wimp programs.

Here are some links about Lua:

The first article in Lua Programming Gems is a refinement of a piece in Foundation Risc User volume 21 called From BEST to RISC. The code is in the textfile ladder.lua which uses the module graph. This provides a single function for computing the connected component of a vertex in a graph.
