Risc Lua

wiki

An implementation of Lua for RISC OS

Available at http://www.wra1th.plus.com/lua .

Compiled with Norcroft v.5.61, linked with the shared Clib.

Differences from standard Lua:

1. #define LUA_NUMBER int

2. No math library, but bitwise operators ~ (not), & (and), | (or), ^^ (xor) and shifts <<, >> instead.

3. Base library extended with rnd and Diego Nehab's protect and newtry.

4. os extended with a directory iterator dir and filetype.

5. New library block for arrays.

6. New library swi for software interrupts.

7. Peter Shook's local x,y,z in t syntax.

9. Hard space lexed as a soft space.

10. `,$,?,!,@ allowed in identifiers.

11. Syntactic sugar: \ for function and => for return.
