Text file parameters

[topten 11]

Is it possible to set the text file parameters? For example in notepad.txt  I can manually set the patameters of page for printing 420x594 mm. How to do it programmatically

What have you tried so far?

Thank you, water for your response.

The thing is I am reading a text file line by line , encoding it base64 and then writing it to another text file. So in the text file it is supposed to be something like

"1"="asdfghasdfghasdfghasdfghasdfghasdfgahsdfghasd"

"2"="asdghjasdghajsdhgajsdhgasdjhgasdjhgasdjhgasdjhgasdjhg" etc

But as a result I am getting the situation when a very long line is broken into 2 or 3 lines and I am getting

"1"="asdfghasdfghasd

fghasdfghasdfghasdfgahsdfghasd"

"2"="asdghjasdghajsdhgajsdhgasdjhgasdjhga

sdjhgasdjhgasdjhg"

 

etc

The code is

$sFilePath = @DesktopDir & "outfile.txt"
$num = _FileCountLines ( $sFilePath )
Local $hFileOpen = FileOpen($sFilePath, $FO_READ)

  for $i = 1 to $num
    Local $sFileRead = FileReadLine($hFileOpen, $i)
    ConsoleWrite ($sFileRead & @CRLF)
    $base64encoded = _Base64Encode ($sFileRead, False)
    filewrite (@DesktopDir & "\infile.txt",  '"'&$i & '"="' & $base64encoded & '"' & @CRLF)
  next

I think, may be this line breaking is happening, because the width of txt file innitially set?

You mean: Even with ConsoleWrite you get 2 or 3 lines which are shorter than the maximum width of the SciTE output pane?

[topten 11]

Yes, right

Sometimes I am getting in 3 lines, something like

"1"="asdfgha

sdfghasdfghasdfghasdfgh

asdfgahsdfghasd"

Instead of

"1"="asdfghasdfghasdfghasdfghasdfghasdfgahsdfghasd"

 

[topten 11]

If to be more precise in consolewrite I am geting such things

"7"="asdasdasdasdasdasdasdasdasdasd"          
"8"="sdftrtytyiyuiyjghnfghfghrtyrgdfsdfw
asdasdasd"            asdasdasdasdasertertertrthgbgfgdf
"9"="qweasdxcvdfgrtyfghvbnghryfgbcv"

According to wikipedia there seems to be a maximum line length of 76 bytes for mime before a CRLF is being inserted.

I see. What I am doing now - I am writing these into txt file and then manually change the "linebreaks on/off" parameter in notepad.  When I manually changes this then all lines are going  without breaks.

I wonder, Can I do anything about that programmatically

 

[water 1,873]

I'm not sure it is sensible to have your script and the base64 encoding function insert CRLF into the result.
I think you should read the while file using FileRead (ignoring CRLF), encode it and then write the result to the output file without adding a CRLF.

[topten 11]

That's the problem. The file should have the structure

"1"="...................."

"2"="...................." etc

If it gets the structure like a

"1"=".....................................

....................

......"

"2"="..........................

............

...."

It will fail. It is a .reg file

I tried to remove @CRLF- after that everythin is becoming even more messy

[topten 11]

But what is interesting.

$hFileOpen2 = @DesktopDir & "\patchcreating\in.txt"
$hFileOpen3 = @DesktopDir & "\patchcreating\out.txt"

$sFileRead = FileReadLine($hFileOpen2, 1)
$sFileRead2 = FileReadLine($hFileOpen2, 2)
FileWriteLine($hFileOpen3, $sFileRead& $sFileRead2)

When I read the ready file's line 1 and line 2 and then write them together into another file they are written into one line as it is supposed

 

[water 1,873]

That's what I said: Looks like the encoding routine inserts the CRLF.

[topten 11]

I have designed quite a hackish way to fix it though

$source = FileRead (@DesktopDir & "in.txt")

$text =  StringRegExp($source, '(?s)="(.*?)"', 3)

for $i = 0 to UBound ($text)-1
$string = StringStripWS($text[$i],8)
filewrite (@DesktopDir & "\out.txt",  '"'&$i+1 & '"="' & $string & '"' & @CRLF)


next

Have to create another file and after that remove those whitespaces. Works, but still not solved, why can't I just directly write into innitial file without those line breaks

[topten 11]

You are right, Water. It is the encoding routine, that is inserting CRLF, I found it in the udf
