Remove Blank Lines in a file


Recommended Posts

DemonWareXT,

Try this SRE - I think it solves the problem:

$sText = StringRegExpReplace(StringRegExpReplace($sText, "(\v)+", @CRLF), "(^\v*)|(\v*\Z)", "")
I was only removing the CR of a CRLF. When I opened the file in NotePad to check it did not honour the remaining 0A with a new line - it was only when I looked with a hex editor I saw the problem. :graduated:

As for the added number I think it happens when you sort your array - try this code:

_ArraySort($Whole, 0, 1)
Must rush to the dentist. :)

Try those out and I will look again when I return. ;)

you saved my life. Thnx a lot!

i'm newbie at SRE. Can i tell that that code works like this:

1- Group and convert any horizontal line feed to @CRLF.

2- Remove @CRLF if it is located at beginning or ending of file.

?

i was using these:

Func __RemoveExtraLines($string)
   Local $i, $s = "", $split
   $split = StringSplit($string, @CRLF, 0)
   For $i = 1 To $split[0]
      If $split[$i] = @CR Or $split[$i] = @CRLF Or $split[$i] = "" Or $split[$i] = @LF Then ContinueLoop
   $s = $s & $split[$i] & @CRLF
   Next
   $s = StringReplace($s, @CRLF, "", -1)
   Return ($s)
EndFunc   ;==>__RemoveExtraLines

waste of time but it works too ^^

@Never say never

your code works too if string doesn't have (for example) @CRLF + @CR in a row.

Please don't necro old posts. It seems you're not getting off to a good start here.

#include <Constants.au3>

Local $sData = FileRead(@ScriptFullPath)


$sData = StringRegExpReplace($sData, '(?m:^\s*[\r\n])', '') ; Empty lines. By guinness.


MsgBox($MB_SYSTEMMODAL, '', $sData)

Hello,
I know it is an old post but...
Looking at https://regex101.com/r/nYWlWA/1
 

StringRegExpReplace(FileRead($s_FileWithEmptyLines),"(?m)^\s", "")

works great for me !

with regex101.com you can even export in Autoit code 😁💖
