Quick question about FileWriteLine

[NiwatiX]

Hey guys, from a performance stand point, which one is best?

FileWriteLine($sOpenfile,"some text1" & @CRLF)
FileWriteLine($sOpenfile,"some text2" & @CRLF)
FileWriteLine($sOpenfile,"some text3" & @CRLF)
FileWriteLine($sOpenfile,"some text4" & @CRLF)

 

Or this one
 

FileWriteLine($sOpenfile,"some text1" & @CRLF & "some text2" & @CRLF & "some text3" & @CRLF & "some text4" & @CRLF &"some text5" & @CRLF)

 

Also if second version is better, any way to split it on multiple line for readability inside the IDE? I'm a C programmer so usually white space isn't a problem out of string, I'm not used to that high level coding. I would assume second version is better since you call only once FileWriteLine, but you know sometime in the wrapper they optimize crazy things and I just want to be sure I'm not mistaken.

NiwatiX,

Why not write a quick script and see? Or do you expect someone else to do all the work for you?

Well I expected someone to just.. know the answer. I'm sorry if you misunderstood my question, I don't want someone to build a script for me lol...  I was wondering how things are aligned by the optimizer.

For future reference this is an example of how to test which of several different methods is the fastest.

#include <FileConstants.au3>

RunTests()

Func RunTests()
Local $sOpenfile = "c:\Temp\TessFile.txt"
Local $Method1Timer = 0
Local $Method2Timer = 0
Local $Method3Timer = 0

    $Method1Timer = TimerInit()
    Method1Test($sOpenfile)
    ConsoleWrite("Method 1 took " & TimerDiff($Method1Timer) & " milliseconds" & @CRLF )

    $Method2Timer = TimerInit()
    Method2Test($sOpenfile)
    ConsoleWrite("Method 2 took " & TimerDiff($Method2Timer) & " milliseconds" & @CRLF )

    $Method3Timer = TimerInit()
    Method3Test($sOpenfile)
    ConsoleWrite("Method 3 took " & TimerDiff($Method3Timer) & " milliseconds" & @CRLF )

EndFunc

Func Method1Test($sOpenfile)
    FileWriteLine($sOpenfile,"some text1")
    FileWriteLine($sOpenfile,"some text2")
    FileWriteLine($sOpenfile,"some text3")
    FileWriteLine($sOpenfile,"some text5")
    FileWriteLine($sOpenfile,"some text6")

EndFunc

Func Method3Test($sOpenfile)
    Local $hFileHandel = FileOpen($sOpenfile,$FO_OVERWRITE+$FO_CREATEPATH )
    FileWriteLine($hFileHandel,"some text1")
    FileWriteLine($hFileHandel,"some text2")
    FileWriteLine($hFileHandel,"some text3")
    FileWriteLine($hFileHandel,"some text4")
    FileWriteLine($hFileHandel,"some text5")
    FileWriteLine($hFileHandel,"some text6")
    FileWriteLine($hFileHandel,"some text7")
    FileWriteLine($hFileHandel,"some text8")
    FileWriteLine($hFileHandel,"some text9")
    FileWriteLine($hFileHandel,"some text10")
    FileClose($hFileHandel)
EndFunc

also

...... any way to split it on multiple line for readability inside the IDE? .......

to split long lines, you can use the underscore sign _ within the IDE:

FileWriteLine($sOpenfile, "some text1" & @CRLF & _
        "some text2" & @CRLF & _
        "some text3" & @CRLF & _
        "some text4" & @CRLF & _
        "some text5" & @CRLF)

Thanks guys for the tips, this is exactly what I was looking for
