Faster 'FileReadLine'?

[Skrip]

Hey guys. I am trying to make a script faster. I need to read EVERY line from a 28,168KB (~350,000 lines) text file, and FileReadLine() does not seem to be very fast. It is reading about 4-6 per second. Each line is between 20-150 characters long.

Is there a faster alternative to FileReadLine?

Or maybe, would an array be faster? What is the limit for how much an array can hold? It might have to hold up 500,000 dimensions....

Go for it! I don't think you'll fill up an array anytime soon...

15. What are the current technical limits of AutoIt v3?

Here are details of the current technical limits of AutoIt. Please note that some of the limits are theoretical and you may run into performance or memory related problems before you reach the actual limit.

Maximum length of a single script line: 4,095

Maximum string length: 2,147,483,647 characters

Number range (floating point): 1.7E308 to 1.7E+308 with 15-digit precision

Number range (integers): 64-bit signed integer

Hexadecimal numbers: 32-bit signed integer (0x80000000 to 0x7FFFFFFF)

Arrays: A maximum of 64 dimensions and/or a total of 16 million elements

Maximum depth of recursive function calls: 5100 levels

Maximum number of variables in use at one time: No limit

Maximum number of user defined functions: No limit

Maximum number of GUI windows: No limit

Maximum number of GUI controls: 65532

And...I just remembered why I hate arrays. lol

FileReadLine() does not seem to be very fast

If you use it without opening the file first then yes, it can be slow...

;Write to file *Around* 28,168 KB
$hFOpen = FileOpen("File.txt", 2)

For $i = 1 To 4650
    FileWriteLine($hFOpen, $i)
Next

FileClose($hFOpen)

;Now we read from that file into string...
$iTimer = TimerInit()

$hFOpen = FileOpen("File.txt", 0)
$sReadLines = ""

While 1
    $sReadLines &= FileReadLine($hFOpen) & @CRLF
    If @error <> 0 Then ExitLoop
WEnd

FileClose($hFOpen)

;Show the time
ConsoleWrite(StringFormat("%i lines in %.2f milliseconds ;)\n", 4650, TimerDiff($iTimer)))

;Show the string to the console
ConsoleWrite($sReadLines)

What is the limit for how much an array can hold? It might have to hold up 500,000 dimensions....

You don't need that much dimentions

16 million elements (wich is the limit) can hold 16 million lines...

;Write to file *Around* 28,168 KB
$hFOpen = FileOpen("File.txt", 2)

For $i = 1 To 4650
    FileWriteLine($hFOpen, $i)
Next

FileClose($hFOpen)

;Now we read from that file into Array...
$aReadLines = StringSplit(StringStripCR(FileRead("File.txt")), @LF)

For $i = 1 To $aReadLines[0]
;Show the current element to the console
    ConsoleWrite($aReadLines[$i] & @LF)
Next
