sc readfile, writefile and text - unreadable outputs

I am seeing some discrepancies on
sc readfile/writefile and
sc text but it may be just me:
if <curitem> is the result of
sc readurl saved as .txt,
Code: Select all
$a = readfile("<curitem>"); writefile("new.txt", $a);
gives different result from
text readfile("<curitem>");
TU for
sc writefile won't do a difference here.
IOW when I pick
sc text I have a read-able output, OTOH if I open a file created by
sc readurl,
sc readfile and
writefile I just have a mess of words with no meaningful spacing at all.

Guys, I badly need help on this.
The problem seems to be the lack of support of custom line feeds which are present on the sc text command so my suggestion is giving sc writefile the same ability. Sometimes it is great to have the original text formatting but in the case I explained in my previous post it is just too bad not being possible to convert documents to a different line feed.

Code: Select all
writefile("d:\Downloads\Stuff\Offline\new.txt", readfile("d:\Downloads\Stuff\Offline\Offline Page.txt", t, , 65000), o, ); run "d:\Downloads\Stuff\Offline\new.txt";
I tried several encodings as attempts based on this page and xy documentation:
http://msdn.microsoft.com/en-us/library ... epage.aspx
If I open the
Offline Page.txt, select all, copy & paste it elsewhere other than notepad (wordpad, for instance), I get the desired spacing. As said, a simple
text readfile(<curitem>); will do. But I need to fix those documents so they are eyes-friendly!

I don't think your description of the problem is complete enough for me to reproduce it. Please give me a copy-and-paste script that will create the error before my eyes.

Code: Select all
writefile("ReadURL Test.text", readurl("http://www.youtube.com/watch?v=rte3kfzNXPg"));
then use this
Code: Select all
text readfile("ReadURL Test.text");
now open it with standard notepad:
Code: Select all
openwith notepad, "ReadURL Test.text";
What was a perfectly readable text-and-code now is just a heavy block of words due to lack of line feeds.
The problem is:
how to force
sc writefile to write the necessary line feeds* info so the saved document
will store spacing in a format notepad will interpret line feeds like
sc text does?
Because if I copy the output from
sc text window into a new notepad document, then
notepad will correctly open it afterwards.
_________
*or
sc readurl to correctly feed
sc writefile, I don't know. But it does somehow, the line feeds are stored as
sc text correctly interprets them.

Yawn. It's a UNIX file and XY says so in its preview Tab. Notepad is too stupid to handle UNIX. That's all.

I think "unix" is only LF (x'0a') for new lines?
Then you could change all LF to CRLF (x'0a' to x'0d0a').
Some editors (and other programs) understand both, some don't ...

It seems that XYplorer won't allow use of "<cr>" and/or "<lf>" for search and replacement.
The following won't do it as well:
Code: Select all
[code]$base = readfile("<curitem>"); $lf = chr(13).chr(10).chr(32).chr(32); replace $base, $base, "$lf", "<crlf>"; writefile("Text Fix.txt", $base);
[/code]
Code: Select all
[code]$base = readfile("<curitem>"); $lf = chr(13).chr(10).chr(32); replace $base, $base, "$lf", "<crlf>"; writefile("Text Fix.txt", $base);
[/code]
Code: Select all
$base = readfile("<curitem>"); $lf = chr(13).chr(10); replace $base, $base, "$lf", "<crlf>"; writefile("Text Fix.txt", $base);
Code: Select all
$base = readfile("<curitem>"); $lf = chr(13); replace $base, $base, "$lf", "<crlf>"; writefile("Text Fix.txt", $base);
So how could I change those, PeterH?

e.g.
Code: Select all
//$name = "<curname>";
$data = readfile("<curitem>");
////match "\n" but not if there is an "\r" before:
$data = regexreplace($data, "([^\r])\n", "$1<crlf>");
text $data;
//writefile($name . "_Win32.txt", $data);

Code: Select all
$base = readfile("<curitem>");
$base = regexreplace($base, "\n", "<crlf>");
writefile("Text Fix.txt", $base);

That will not only replace \n to \r\n
but also replace \r\n to \r\r\n
in files with mixed LE
or for files with windows LE only, processed by accident.

Hey: nobody looked what you did wrong?
So:
*what* did you try to replace???
I said x'0a', that's decimal 10, isn't it?
I don't understand the idea of your first 3 examples.
But if, in the last version, you replace chr(13) with chr(10), you would be lucky.
(And if your scripts would have a better form people reading them would be more happy
)

Those were attempts to get the replacement done.
I'll keep the readability on the back of my mind, sorry......
Stefan, I understand your worry but highend's solution did he job.
For a reason I can't tell your script eliminates the closing ">" on several lines, thus damaging the original code.

Still I don't understand the idea...
If chr(13) isn't found, anything concatenated with chr(13) will not be found at all, isn't it?
(Imagine words: if a text doesn't contain "to" it will surely not contain "today"...)
So I'm afraid there is some problem in your understanding of replace()?
(
note my writing of the
function replace
() 
)

Right, it works for any line ender, "\n" and even "\r\n" or both mixed inside an file.
But the point is it should not work if you have already windows line enders "\r\n" because you get "\r\r\n" then.

Oh silly me
Of course
it's wrong, i see now.
I have modified now my expression above. Sorry.
