Detecting and converting line feeds

hello,
I want to convert the 'enters' from a text field to <br>'s in the html code later on...
I tried using a breakIterator, but this doesn't seem to work too well...
Any ideas how this is done?

Folder action to find and replace text and change line feeds

I want to use a folder action to find and replace text and change Mac carriage returns to DOS line feeds inside text files.
The text to be replaced is: "/Users/wim/Music/iTunes/iTunes Music/Music" (without the quotes)
This text has to be removed (i.e. replaced by an empty string)
The text occurs many times within each file.
The files are playlists exported from iTunes in the M3U format (which are text files). They contain Mac carriage returns. These need to be changed to DOS line feeds.
I have found the following two perl commands to achieve this:
To find and replace text: perl -pi -w -e 's/THIS/THAT/g;' *.txt
To change carriage returns to line feeds: perl -i -pe 's/\015/\015\012/g' mac-file
I know that it's possible to make a folder action with Automator that executes a shell script.
What I want to do is drop the exported playlists in M3U format in a folder so that the folder action will remove the right text and change the carriage returns.
My questions are:
Is it possible to make a folder action that executes command line commands instead of shell scripts?
What is the correct syntax for the two commands when used in a folder action shell script? Especially, how do I escape the slashes (/) in the string to be removed?
Thanks for your help

Ok, I've include an applescript to run a shell command. The applesript command quoted form makes a string that will end up as a single string on the bash command line. Depending on what you want to do, you may need multiple string on the bash command lines. I've included some information on folder actions.
It is easier to diagnose problems with debug information. I suggest adding log statements to your script to see what is going on. Here is an example.

How to find a carriage return and Line feed?

I need to detect if a crriage retunr and line feed present on each row in my text file before allowing user to upload the text file
I know how to remove them from each line but what I need is to detect them no removing them from file.
Our concern is when the a row does not have carriage return and line feed.
Is there a way to find this using CF? Please help
thanks

That is exactly the problem Dave, if some rows do not have line feed, they're not being inserted into DB, it skips other steps and go right to finish. It looks
like the file is done processing.
So I need to do early rejection to this kind of file.
I used cfloop to catch anything else that do not follow the formatting rules.
Here is what I already done:
Right after the file got uploaded, I have these codes:
<cfloop index="x" file="#MyFile#" >
<CFSETMyLine = Replace(x,chr(9),"|", "ALL")>
I'm using a few functions, such as, Left(), Mid(), Right(), etc to make sure certain rules are followed.
Up till here, it's done and tested, everything is working.
The only problem is when 1 or more rows don't end up with line feed and or carriage return.
I plan to add some codes to check the end of each row for chr(10) since it is looping for every row anyway.
If detected, process file normally otherwise stop processing.
</cfloop>
So this can't be done in CF?

File adapter and line feeds

Hi,
we need to produce a flat file using the content conversion of the file adapter without any line feed (the target structure is a complex one with several record types).
Example
What we get now:
*AAheaderA
*ABheaderB
*BAItem1
*CAsubitem1
*BAItem2
What we need:
AAheaderAABheaderBBAItem1CAsubitem1*BAItem2
It seems that with NameA.endSeparator parameter you can only add a new character, but I need to delete the line feed.
Is it possible with standard file adapter or do we need do create our own module with java?
Thank you.

Hi Stefano,
So you Basically want to do content conversion at the receiver end and that is basically to get the entire data in one line.For that please go through these links below.It clearly explains your requirement.

Converting strings with line feeds to a single line with identifying chars

Hi, I dont want to re invent the wheel if there is something out there that does this already. I want to take some string with multiple
line feeds and convert it to a single line. For example:
"I want this string
to be changed to
a single line"
to this...
"I want this string\r\n to be changed tor\\n a single line"

vsekvsek wrote:
OK, Hope this will make better sense. So right now a I have a routine that loads files like below:
"TEST\r\n TEST1\R\n TEST2"It's not clear to me at this point what you mean by that string.
After the initial word TEST, does that string have a backslash character followed by an r followed by another backslash followed by an n? Or does it have a carriage return followed by a line feed. (\r followed by \n)
We format it when loading in a way that it will look like this when queriing from the DB
"TEST
TEST1
TEST2"It doesn't look like anything "when querying from the DB." That part doesn't make any sense.
Either the string has a backslash followed by an r, in which case when you render in in a text editor or on a console it will look like a single line with a visible backslash character followed by an r, or it has a carriage return (\r) in which case it will look like multiple lines when rendered in a text editor or on a console.
Later I re-extract it to a file from the DB and What confuses me is when I inspect the string it looks like this
"TEST\r\n TEST1\R\n TEST2"How are you inspecting it? If it's in a debugger or similar tool, it's not uncommon for it to be showing a carriage return character (\r) as a visible backslash followed by an r, rather than interpreting it and rendering a new line. This is so that you can see exactly what characters are in there, rather than wondering about the specific whitespace.

but it extracts to my file like
"TEST
TEST1

So I guess there are some hidden cr's or something messing it up that I need to manipulate but not sure how to apprach it?I still don't know what you're trying to do, or if you even have an actual problem with your data or are simply not understanding what you're seeing.

How to output sample and convert clocks to PFI lines of E-Series DAQ (DAQPad-6015)

Hi,
Can someone tell me how to output sample and convert clocks to PFI lines of E-Series DAQ (DAQPad-6015)?
Thank you very much.
Jack

John --
Windows is not an option for me. I like your idea of using a counter output -- it may be helpful as I am getting ramped up, but my application will eventually require both timer outputs.
I have a legacy C application written for Macintosh, and I am in the process of moving it onto OS X. So my options are to use DAQmx Base, or write an in-kernel driver. I actually have already done the latter for 6024/6025 E-series boards (for another company); for this client I was hoping to use the DAQmx Base to allow an easy transition to M-series boards, without the cost of writing and supporting a low-level driver.
The specific task I am doing is relatively straightforward. I record 2 channels of AI for a short period (usually about 250 ms.) and during this time I drive 2 external digital signals. Right now, I use the 2 timer outputs, which allows precise synchronization with the output and AI sampling.
I appreciate your comments, and thanks in advance for any additional suggestions you can lob my way.

When I copy and paste text in facebook, the text looks fine until I hit 'share' or 'comment' to submit it. Firefox then adds indiscriminate line-feeds within the text and it looks nothing like the original text. It makes it very difficult to read and awful to look at.
This does not happen in Safari.
(Mac OSX 10.6.4 with Firefox 3.6.6).
== URL of affected sites ==
http://

Same problem, 3.6.8 and previous recent versions. I never thought to try another browser but I just pasted into IE and it worked fine. I copied from Firefox to IE and it worked as well. It's just when you paste into Firefox that you get the weird line breaks.

Carriage Returns, Line Feeds, and Tabs in Text Area

I am having users copy and paste data from an Excel spreadsheet into a textarea on a BSP page. When they submit this, since there are tabs and line feeds in the data, the BSP does not recognize the data. The value in the field comes through as blank. When I manually type something into this field, with out any carriage returns, tabs, etc., the value does not come through as blank? Does anybody know how to get around this?

HI
Iam uploading the data from application server(AL11) to other server.
In the GLPCA-SGTXT(Table) iam having some text like 'This is good ##'.i was downloded some other data with this text('This is good ##') by using report program in to aplicationserver(AL11) and from there iam uploading that data into other server.
But here the problem is in the UNIX, it was showing some problem.
That is actually it need to show the format like:
001 256 786 This is good## 459786
But here it was showing like:
001 256 786 This is good^M
459786
So here '459786' is coming to next line. But i need this '459786' also in the same line.
I am not sure if it is possible to remove CR and LF's using the code the program is written in, but that is what we need to do. In Unix ^M is the CR (Carriage return), but I am not sure what LF is?

Text mode opened file and line feed

Good morning:
I have open a file in text mode and i need to send an OD0A hexadecimal characters to another system in each line, if i try to put 0D0A it makes a double line feed and if i only put 0D it doesn´t interpretate 0D like hexadecimal characters, i know that if i open the file with binary mode it would be very easy, but it is a code shared with another programs, so i rather not to change. Does anybody has made that in text mode in any occasion?.
Thanks in advance

Find the LINE FEED and replace it.

Hi
I am using ORACLE 11g R2. I am having some text data in a variable as below :-
Variable = V_TEXT
V_TEXT :=
'/u01/oracle/data/file1.txt
/u01/oracle/data/file2.txt
/u01/oracle/data/file3.txt'I want to place an '|' (pipe symbol) at the end of each line. So the expected output is as below :-
'/u01/oracle/data/file1.txt|
/u01/oracle/data/file2.txt|
/u01/oracle/data/file3.txt|' I tried with replace() function and replaced return character i.e. CHR(10) with '|' but it gives me an wrong output and also at the end of last line we dont have an return character.
after searching a lot on internet I found that i can do this with the help of regular expression.
As far as i have studied : -
The line feed character is the last character in the line or we can say it is end of line. This character is noted in oracle as 'x0a'
I want to replace this character in every line and place an '|' symbol.
can anyone guide me how to do it ??
Thanks in advance.

Aha... Now that is a different expected output as in your original post ;-)
One way of doing it could be something like this:
declare
v_text varchar2(32767) := '/u01/oracle/data/file1.txt
/u01/oracle/data/file2.txt
/u01/oracle/data/file3.txt';
begin
v_text := regexp_replace(
regexp_replace(v_text,chr(10)||'\s*'||chr(10),chr(10))
,'$','|',1,0,'m'
dbms_output.put_line(v_text);
end;
/Inner regexp replaces "linefeed followed by zero or more whitespace followed by linefeed" with a single linefeed. So this removes the blank lines.
Then the outer regexp takes care of the | characters.
(It might be possible to wrap it up in a single regexp, though I can't think of a way just off hand ;-) )

Mail attachment generated in UDF in SAP PI 7.1 - Issue with line feed

Hello,
Situation is:
Implemented a scenario in SAP PI 7.1 with a mail receiver following this thread:
/people/samuel.chandrasekaran2/blog/2008/10/06/xi-mail-adapter-dynamically-building-attachment-and-message-body-content-using-a-simple-udf
which is about moving message lines from sender into an attachment forn the receiver mail.
It is working great!
The receiver gets the mail including the attachment with all added lines.
But when opening this mail there is an issue depending on the program we are using to open the attachment
which is defined as txt file
- Using MS Editor 5.1 (Windows XP 2007, SP3) the Carriage returns and line feeds (added with
in the UDF) to separate the message lines are not recognized. In the Editor each
    is shown as □   within the text. Word wrap (flag set in the editor) is different to the carriage return/line feeds set in the file.
- Using MS Notepad 5.1 (Windows XP 2007, SP3)   situation is the same but
    is NOT shown as □ , it simply seems to be unvisible. Word wrap (flag set in the editor) is different to the carriage return/line feeds set in the file.
- Using Word 2007 the carriage returns are recognized and used in a correct way to display the file content. But now mutated vowels (äüö) are not recognized. They are displayed as
So I followed this thread:
http://help.sap.com/saphelp_nw04/helpdata/en/96/f04142099eb76be10000000a155106/content.htm
Nice....
In the editors there is no change, but when opening the file in Word it asks now how to convert the file content
(proposing UTF-8) and Word recognizes mutual vowels.
But there seems to be a side effect....
Following the second link, PI recognizes an error.
This is the error message.
MP: exception caught with message Null as XI message received (PrincipalData in ModulData is null)
Adapter Framework caught exception: Null as XI message received (PrincipalData in ModulData is null)
Delivering the message to the application using connection Mail_http://sap.com/xi/XI/System failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.lang.Exception: Null as XI message received (PrincipalData in ModulData is null).
But the message is sent to the mail recipient which could be ok if PI would not repeat the mail sending now for several times.
So we will receive not one but a number of mails.
So we removed the modul recommended in this help link from the channel.
Result: Behaviour in Word changed now to the described one. But the errors are no longer coming up in channel monitoring incl. message send repetition. So this is a first success. But the partner wants to process the files first with one of the named editors. So we are looking for another solution now to fix the last issue!
Your ideas are really welcome!

Hi,
as I found this in wikipedia:
Another common problem is the use of '\n' when communicating using an Internet protocol that mandates the use of ASCII CR+LF for ending lines. Writing '\n' to a text mode stream works correctly on Windows systems, but produces only LF on Unix, and something completely different on more exotic systems. Using "\r\n" in binary mode is slightly better, as it works on many ASCII-compatible systems, but still fails in the general case. One approach is to use binary mode and specify the numeric values of the control sequence directly, "\x0D\x0A".
Back to my issue:
In the UDF I am adding "\r\n" but only the "\n" seems to survive!
In Mapping test line feeds are available and the lines are shown as expected.
Using Notepad ++ to open the created txt file from the mail shows that LF is in the file at each end of line but CR is missing.
CR is only at the end of the last line in the file and is not from the UDF that creates the mail or the UDF that creates the attachment lines. Seems that this is added somewhere else behind the mapping.
This is what I found in galileo computing
(http://www.galileocomputing.de/glossar/gp/anzeige-11241/FirstLetter-Z, SORRY, only available in german language!):
In Parsing of XML-Documents the XML-Parser changes the end of line delimiter internally in general to a simple line feed (LF, #0A) as usual in UNIX. ..... In Windows this could result in problems with readability of source texts (e.g. in Notepad) which can be solved by choosing the right editor.
My target application is on Windows and not able to "choose" the right editor (PI system is on windoes OS too) !
But Im wondering where the CR at the end of the text comes from when all the \r\n will be replaced with \n as described.
Ideas are really welcome!
Best regards
Dirk

Best way to remove last line-feed in text file

What is the best way to remove last line-feed in text file? (so that the last line of text is the last line, not a line-feed). The best I can come up with is: echo -n "$(cat file.txt)" > newfile.txt
(as echo -n will remove all trailing newline characters)

What is the best way to remove last line-feed in text file? (so that the last line of text is the last line, not a line-feed). The best I can come up with is: echo -n "$(cat file.txt)" > newfile.txt
(as echo -n will remove all trailing newline characters)
According to my experiments, you have removed all line terminators from the file, and replaced those between lines with a space.
That is to say, you have turned a multi-line file into one long line with no line terminator.
If that is what you want, and your files are not very big, then your echo statement might be all you need.
If you need to deal with larger files, you could try using the 'tr' command, and something like
tr '
' ' ' <file.txt >newfile.txt
The only problem with this is, it will most likely give you a trailing space, as the last newline is going to be converted to a space. If that is not acceptable, then something else will have to be arranged.
However, if you really want to maintain a multi-line file, but remove just the very last line terminator, that gets a bit more complicated. This might work for you:
perl -ne '
chomp;
print "
" if $n++ != 0;
print;
' file.txt >newfile.txt
You can use cat -e to see which lines have newlines, and you should see that the last line does not have a newline, but all the others still do.
I guess if you really did mean to remove all newline characters and replace them with a space, except for the last line, then a modification of the above perl script would do that:
perl -ne '
chomp;
print " " if $n++ != 0;
print;
' file.txt >newfile.txt
Am I even close to understanding what you are asking for?

Losing Line-feed in XML parsing (XMLTRANSFORM) or File output (clob2file)?

Hi all, need some help please!
I'm using a xslt file to transferm a XML file into a txt format file. Within the XSLT file, there is a carriage-return (<xsl:text>
</xsl:text>) (it disappeared already, here is what i'm using "#xD" or "#xA", have to take the '&' and ';' away), but the final output txt file seems to lose this carriage-return/line-feed information. The output data became one-line.
Here are the steps I've used:
1. lv_xml_data = XMLTRANSFORM (a.xml_data, b.f_xslt)
=> output data into XMLTYPE;
2. using XMLTYPE.getclobval to get the output data into CLOB format.
lv_output_clob := XMLTYPE.getclobval (lv_xml_data);
3. using encoding:
lv_output_clob :=
DBMS_XMLGEN.CONVERT (lv_output_clob, DBMS_XMLGEN.entity_decode);
4. using clob2file write to a file with txt format.
DBMS_XSLPROCESSOR.clob2file (lv_output_clob,
lv_output_dir,
lv_filename,
NLS_CHARSET_ID ('UTF8')
Been struggling with these a few days already. Any help is appreciated. I would really like to get some input to see what might cause the carriage-return/line-feed characters lost.
Thanks in advance!

A_non,
After a few testing, I can identify the CRLF was lost in XMLTRANSFORM. I had read your other thread related to this, and try to run this sample code:

Can not figure out why. Try to use this <xsl:variable name="new_line" select="''& # x A ;''" /> inside my style sheet, but it seems not taking it. Not too sure what's exactly should be the quotes for "''& # x A ;''" (w/o space). If I used doub quote + two single quotes, it returns error, LPX-00601: Invalid token in: ' '; if I used single quote + double quote, it did not bring in CRLF at all.
Any input?
Thanks in advance.
