Title: ptokax and Lua 4.0
Post by: c h i l l a on 06 January, 2004, 21:27:11

so I have this huge file with 100.000 entries for a trivia bot, well I decided not to load all of it into memory.

but i also don't want to run through the file again and again, when getting new questions...

so thaught, why not seek through the file on startup, store the seeks in a table and... then get those random seeks, and read from line.

okey, problem is, actually only, that LUA will always set the curser, to the beginning of a line = read(handle) but ptokax won't, any idea why, I get 2 different results when I use ptokax and the other time lua 4.0.

here is my func.

Code Select

function ReadSeek(QFile)
	handle2 = openfile(QFile,"r")
	if handle2 then
		local line = read(handle2)
		while line do
			local sek = seek(handle2,"cur")
			line = read(handle2)
			tinsert(seeks,sek)
		end
		closefile(handle2)
	end
	local handle = openfile("testseek.txt","w")
	for i = 1,getn(seeks) do
		write(handle,seeks[i].."\r\n")
	end
	closefile(handle)
end

other question.. does a set seek, take as long as a

local line = openfile(blabla)
var = 0
while line do
var = var + 1
if var == XX then
Line to get
end
end
