return numbers from a log (.txt)

I have been trying to read a log file in order to get the numbers from it. The list in the log file looks something like this:
Tried using this function:
Code: Select all
function checkSlots()
local lines = {}
local filename = getExecutionPath() .. "/logs/"..player.Name..".txt"
local file, err = io.open(filename, "r");
if( not file ) then
print("File not found");
else
-- read the lines in table 'lines'
for line in io.lines(filename) do
table.insert(lines, line)
end
table.concat(lines, "\n")
for k,v in pairs(lines) do
local number = file:read(k, "*n")
print(number);
end
file:close()
end
end
but it returns
Code: Select all
Command> checkSlots()
Sl
ot
72
75
77
nil
I am trying to do something like
Code: Select all
for k,v in pairs(lines) do
local number = file:read(k, "*n")
if type(number) == "number" then
item = inventory.BagSlot[number]
if not (item.Id == 208679 or item.Id == 208682 or item.Id == 0) and item.Quality < 3 then
print(item.Name)
end
end
end
Basically trying to get the number's in the list into the variable number. Keeps coming up with nil value.

Let me see
Code: Select all
function checkSlots()
local lines = {}
local filename = getExecutionPath() .. "/logs/"..player.Name..".txt"
local file, err = io.open(filename, "r");
if( not file ) then
print("File not found");
else
-- read the lines in table 'lines'
for line in io.lines(filename) do
table.insert(lines, line)
end
At this point you have a table with the whole contents of the file. At this point you could close the file because you don't need it anymore.
This line does nothing. It concatenates the table but does nothing with the result. 'lines' remains unchanged.
Code: Select all
for k,v in pairs(lines) do
local number = file:read(k, "*n")
print(number);
end
This doesn't make sense. Why are you rereading the file? It looks like you think that the first argument of read is the line to be read but from online references it seems to be the number of bytes read.
What I would do is use the existing line values and use tonumber on them.
Code: Select all
function checkSlots()
local lines = {}
local filename = getExecutionPath() .. "/logs/"..player.Name..".txt"
local file, err = io.open(filename, "r");
if( not file ) then
print("File not found");
else
-- read the lines in table 'lines'
for line in io.lines(filename) do
table.insert(lines, tonumber(line))
end
file:close()
for k,v in pairs(lines) do
item = inventory.BagSlot[v]
if not (item.Id == 208679 or item.Id == 208682 or item.Id == 0) and item.Quality < 3 then
print(item.Name)
end
end
end
end
This seems to work.

Thank you, works
First time trying to figure out how to read log files, hence the random pointless crap xD
