How to detect CRLF at end of text file

[DickG]

I have a text file whose last line ends in a CRLF (seen by using SciTE's View > End of line). There is an empty line below it and it's last.

I've tried _FileCountLines(), but it ignores the last line if it's empty. So although SciTE shows the last line as empty, FileCountLines() tells me it's 22 (instead of 23, for instance).

I've tried reading the last line with FileRead(), then using StringRight($Last_line, 1), but it does not see the CRLF.

Is there a way to determine if the last line is empty?

DickG,

I would suggest reading the whole file and then checking if there is a @CRLF at the end:

$sContent = FileRead("File_Path")
If StringRight($sContent, 2) = @CRLF Then
    ConsoleWrite("Blank line" & @CRLF)
Else
    ConsoleWrite("No blank" & @CRLF)
EndIf

Note that @CRLF is actually 2 characters (@CR & @LF or 0x0D0A).

FileReadLine ( "filehandle/filename", -1 ) 
Edit : doesn't work

Not sure, but it should work :

$sContent = StringRegExpReplace(FileRead("test.txt"), "\r\n(?=\r\n)$", "" )

Thank you, Melba! That worked for me! My mistake was checking only the last character.
