Hi, This becomes interesting for me: when I read with dofile, the array data several times are in main memory: 1) when I read the chunk (this could be modified, though) 2) in the bytecode 3) in the

My last post responded to the wrong comment ... Sorry You can use lua table with arbitrary base by using the hash part: local T = {[0]=0, 1} -- 0-based critical table Above is actual code of my prim

?... ?I hate one-based indexing?. It adds a ton of confusion when embedding lua into a native programming language project, and tarnishes what I'd consider to be a fantastically good language otherw

Not so; even if you disregard COBOL (which is still pretty widely used), I would bet that SQL (which also uses 1-based array indexes) is much more commonly used than Lua. -- Andrew.

Cool. That's a very enlightening answer. Thanks Mike. -gary Gary Bringhurst wrote: I've been timing table accesses under LuaJIT using various key types in a very simple tight loop. Positive integers

Your benchmark is flawed in several ways: - Quite a bit of the runtime is used by calling random(). ==> You're not only measuring what you intended to measure. - The size of the created tables is too

Hello, I've been burning some midnight oil lately. Anyway, here are the results of my experiment with adding arrays to Lua. The experiment demonstrates significant performance increase in some cases,

http://www.lua.org/source/5.1/lstring.c.html Lua strings are technically an array (or sequence) of (char)s, That way they are also accessed binary from files: http://www.lua.org/source/5.1/liolib.c.h

You can use lua table with arbitrary base by using the hash part: local k = {[0]=0, 1} -- 0-based table Above is actual code of my primepi.lua (line 20) Doing it in 1-based array is messy and slower
