Re: Version best suitable for restricted environments

[Asko Kauppi <askok@...>]

Any version >= 5.0.2 is rather fine.  Lua people often use a bit  
older versions, if they provide the features they want.

What are your uc capabilities (RAM size, FPU or none)?

Wiki (http://lua-users.org/wiki/) is worth a look, but often  
outdated, and reference to which version (Lua 4 or 5) is not always  
explicitly stated.

src/luaconf.h is your first place to look; one can customize Lua to  
use any number type (almost), only integers etc. If you want  
performance but no functionality crippleness, there's also a known- 
good but experimental integer patch for this usage: http:// 
luaforge.net/frs/?group_id=214

Prepare to have 100-200kB for code (you can strip parts of Lua easily  
off, if you need).  Some 100+ kB of RAM, depending on your use (bare  
launching Lua takes some 40kB). Search the list for more comments  
from people along the years.

Lua 4 and Lua 5 are not very different, when it comes to their  
requirements.
