FileWriteLine - Remove the last @CRLF blank line

[_Vlad]

Hello Autoit,

I have a problem with FileWriteLine trying to remove the last blank line that this function adds.

I don't understand why is it so hard to remove the last blank line. if I put the text in an array then the last line will not show up or if I try to count the lines with _FileCountLines the last line it will not take in count. How can I remove this simple line, without using _FileWriteToLine.

 

Thank you!

Regards

You could use FileWrite() instead of FileWriteLine(), since it adds automatically the carriage return/line feed to the end of the line.

Yes it would have been a good solution, but this will not work if I want to copy a file from one point to another that has already a blank line.

Just check if the string's last 2 characters are @CRLF.  Something like this should work :

Local $sString = "Something that has a carriage return and line feed at the end" & @CRLF
FileWrite("Test.txt", StringRight($sString,2) = @CRLF ? StringTrimRight($sString, 2) : $sString)

Local $hFileOpen, $sText, $sTextNew = ""
$sText = "This is Line 1" & @CRLF & "This is Line 2" & @LF & "This is Line 3" & @CR & "This is the last Line" & @CRLF
$sTextNew = StringRegExpReplace($sText, "(?m)\.*?\R$", "")
$hFileOpen = FileOpen(@ScriptDir & "\testfile.txt", 2) ; 2 = $FO_OVERWRITE
FileWrite($hFileOpen, $sTextNew)
FileClose($hFileOpen)

This would remove @CRLF as well as @LF or @CR at the end of the last line.

Why not use StringStripWS($sString, 2) ;~ Removes trailing white space, you can also use _FileWriteToLine to write to a specific line.

Good point @Subz   Sometimes we forget about those
