The file was generated by processing a markdown file, which as you can see has broken lines at around 80 characters. Using Perl or sed or awk (I'm running Linux so could use any solution but I not much of a Python or Ruby user), how can I undo the breaking of lines within paragraphs?
I know how to strip \n from an entire file, but that would run the two paragraphs shown into a single unbroken line. I don't want that. I just want to operate a paragraph at a time, so any solution should skip lines where \n is the only content.
The file I have uses Unix/Linux file-endings, i.e. line feeds, hence only \n are present. I do need to preserve the spaces between paragraphs.
Breaks/newlines are replaced with space char,
perl -00 -lpe 's|\r?\n| |g' file
Here is brief explanation of switches, and deparsed source
perl -MO=Deparse -00 -lpe 's|\r?\n| |g' file
BEGIN { $/ = ""; $\ = "\n\n"; } # see below
LINE: while (defined($_ = <ARGV>)) { # -p switch
chomp $_; # also -l switch
s/\r?\n/ /g;
}
continue {
print $_; # -p switch
}
-00 => $/ = ""; # input record separator set to paragraph mode
-l => $\ = "\n\n"; # output record separator set to $/
Try to chomp() last newline when a regular expression matches any line with a non-blank character:
perl -pe 'chomp if m/\S/' infile
EDIT: To keep a blank line between paragraphs and a final newline character, try the following:
perl -pe 'm/\S/ ? chomp() : print "\n"; END { print "\n" }' infile
Without having to read the whole file into memory:
$ cat file
Lorem ipsum dolor sit amet. Velit et ornare feugiat ve fringilla adipiscing, non
augue risus, eleifend. Laoreet a, taciti porttitor mus. Erat leo metus
venenatis. Natoque eni, nunc quis elit est.

lines where \n is the only content.
means at least two consecutive newline chars.
You can do it easily with regex. A regex pattern would be (?:[^\r\n])\n(?:[^\r\n])
A sample python file
import re
mystring = """sjdfkj
adlfklk
dlkfl """
print re.sub(r"(?:[^\r\n])\n(?:[^\r\n])"," ",mystring)

Can't seem to wrap my head around the proper regex!
MY GOAL
add 2 spaces to each line of a selected block of text
MY CONTEXT
some markdown tools I used need 2 spaces at the end of each line to properly manage lists, etc.
if a file is edited multiple times, I do not want to end up with lines ending with 4+ spaces
a block of text can be a line, a paragraph, the whole file content as shown in the editor
I have some kind of macro in Notepad++ that does the trick but I want to do the same with Autohotkey to be editor-independant

You're getting too many lines in the output because the send command is messing up due to the carriage returns, which aren't needed in there anyway. I don't really know why that is happening, and I can't be bothered to find out why since the approach isn't good anyway.
And also your indentation is getting messed up because your text editor automatically adds indentation based on the previous line.
But anyway, sending such (long) input is never a good idea.
Make use of the clipboard and just send a ctrl+v to instantly and reliably paste in the text.
Here's an example of that along another way to add the spaces at the end:
inp := "

SendInput, ^v
The ternary A_LoopField = "" ? "" : RTrim(A_LoopField) " " returns true if the line was empty and then the two spaces aren't added at the end.
I think that's the behavior you were doing for.
And RTrim is used to trim any trailing spaces (or tabs) off the end, so we're sure to end up with just the two we want.
And, of course, at the end of any line we add one line feed `n.
Also, your Regex approach was just fine as well at first it just seemed off to me, but well, here's another way. And I guess this would be more efficient, though you'd have to work with seriously large inputs and/or slow hardware for that to make any meaningful difference haha.

I write in Perl.
I need to split a string into first 50 words (or the entire text if there is less than 50 words total) and the rest words (empty string if the first is not above 50 words).
In the first part (first 50 words) and the second part (the rest) the word separators should be preserved: newline should remain newline and space should remain space.
Assuming that by word you mean just a sequence of non-whitespace characters, this can be done simply using a single regex. The one below looks for N-1 consecutive sequences of non-whitespace characters followed by whitespace characters, and then a further stretch of non-whitespace characters. This is the first part of the string. Any following whitespace is skipped, and then the rest of the string forms the second part.
I have used the /s modifier so that a dot . within the regex matches any characters, including newlines. The /x modifier allows for insignificant whitespace within the regex to make it more readable.
Thanks to #knarf for the data.

I am trying to create a script which takes file from the user, encode it in base64 and then forward it to an email as attachment with encoded file.
This is the code till now :
Client side :
<form action="send.php" method="post" enctype="multipart/form-data">
<input type="file" name="uploaded_file">
<input type="submit" value="Submit" name='submit'>
</form>
PHP Script (send.php)
<?php
$uploaded_file = basename($_FILES['uploaded_file']['name']);
$file_size = filesize($uploaded_file);
$handle = fopen($uploaded_file, "r");
$content = fread($handle, $file_size);
fclose($handle);
$content1 = base64_encode($content);
$my_file = "'$encoded_file' . '_encoded' . '.html'";
$handle1 = fopen($my_file, 'w') or die('Cannot open file: '.$my_file);
fwrite($handle1, $content1);
$from="tes#gmail.com";
$to="myemail#gmail.com"
$subject="New file";
$message="you got a new file";
mail($from,$to,$subject,$message);
unlink($my_file);
?>
I don't know how to attach $myfile in the email.
You can just use PHPMailer
$mail = new PHPMailer(); // defaults to using php "mail()"
$body = file_get_contents('contents.html');
$body = preg_replace('/[\]/', '', $body);
$mail->SetFrom('tes#gmail.com', 'First Last');
$mail->AddReplyTo("tes#gmail.com", "First Last");
$mail->AddAddress("myemail#gmail.com", "John Doe");
$mail->Subject = "New File";
$mail->AltBody = "you got a new file";
$mail->MsgHTML($body);
$my_file = file_put_contents("tmp.html", base64_encode($content));
$mail->AddAttachment($my_file); // attachment
if (! $mail->Send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Message sent!";
}
If you're not using any external mail libraries such as PEAR::SMTP or Swift then creating the attachments is not a simple thing.
You will have to check the mail standards they instruct on how to separate the headers from the message content and the message content from the attachments.
The separator is \r\n and each section must be preceded by a separator.
Check this link out: http://webcheatsheet.com/php/send_email_text_html_attachment.php
And my code example:
$uid = md5(uniqid(time()));
$header = implode("\r\n",
array(
'MIME-Version: 1.0',
'From: Address <address#example.com>',
'Reply-To: Address <address#example.com>',

How does Kentico calculate the length of inputted content in a text area on a form and how much value does it give to a line break? A line break is 2 characters according to my JavaScript calculation but seems like Kentico calculates it as being more than 2 characters.
Summary of problem:
I have a maximum length of 2500 set on a text area input on a form on my Kentico site.
I have entered some text into a this text area and with my JavaScript calculations (used to show how many characters the user has left) the character length is exactly 2500 (including line breaks and spaces) and so should therefore validate and send. However Kentico is failing my input saying that my max length has been exceeded. See below:
If I remove the line break and type some extra characters to bring my character calculation back up to 2500, the form sends without failing.
Test used that fails:

The problem lay in the fact that my calculation in my JavaScript gave a length of 1 to a line break whereby Kentico's calculation gives a length of 2 to a line break. So they weren't matching up. Hence my character counter said that the length of the entered text was ok but Kentico's check deemed it over the max length.
This is what I had previously:
enteredText = textareaVariableName.val();
characterCount = enteredText.length; //one line break entered returned 1
This is what I have changed it to:
enteredText = textareaVariableName.val();
enteredTextEncoded = escape(enteredText);
//next I match any line break characters - %0A - after encoding the text area text
linebreaks = enteredTextEncoded.match(/%0A/g);
(linebreaks != null) ? linebreaksLength = linebreaks.length : linebreaksLength = 0;
characterCount = enteredText.length + linebreaksLength; //one line break entered now returns 2
Is there a better way I could check for line breaks in the text, rather than to encode the text and then check for the substring %0A ?
EDIT/UPDATE: I believe the following is a better solution as opposed to what I was doing above.
var limit = 2500; //for example
enteredText = textareaVariableName.val();
numberOfLineBreaks = (enteredText.match(/\n/g)||[]).length;
left = limit - enteredText.length - numberOfLineBreaks;
if (left < 0) {
//character count over code here
} else {
//character count within limits code here
}
This is basically JavaScript problem related to browser. In Firefox or Chrome or any other WebKit based browser textareaVariableName.val().length will count only 1 character for new line (\n). Same for jQuery implementation. But in IE document.getElementById('textareaVariableName').value.length will count 2 for new line (\r\n)
In Kentico, the text is validated to the actual count of characters and therefore the validation is failing.
Quick fix for this is simple regular expression for counting the actual length:
function getTextLength(elementId){
if (elementId) {
var elem = document.getElementById(elementId);
if (elem) {
var str = elem.value;

I'm writing an application [a Pidgin plugin, actually], which inserts an image embedded into a GtkTextBuffer. Currently, I add it using:
gtk_text_buffer_insert_pixbuf(textBuffer, &iter, pixbuf);
However, this just puts the image "inline" with the text. What I'm looking for for is something similar to HTML's "float". For example, assuming my image is about twice the size of a line of text, I current get this [where X is the image]
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Etiam gravida

XXXX ante in massa dignissim aliquam. Nullam tempus quam luctus eros volutpat laoreet.

Mauris semper, nunc quis gravida molestie,

Ideally, I'd like to have:
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Etiam gravida
XXXX ante in massa dignissim aliquam. Nullam tempus quam luctus eros volutpat laoreet.
XXXX
XXXX sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.
XXXX Mauris semper, nunc quis gravida molestie,
leo neque imperdiet nulla, vel consectetur nisi nisl non metus. Maecenas pharetra
magna nec magna mattis faucibus convallis nibh
Note that there are four paragraphs, where the second and third have an image in the beginning.
Is this possible?
The short answer is no; images in TextView are just treated as a character (which may be a lot bigger than a usual character). There isn't any layout engine in the HTML sense. (Layout is limited to what PangoLayout can do.)
You could probably hack something together, using an approach such as:
leave a margin the size of the image on your paragraph
add an expose event handler to paint the image to the window (see the "border windows" examples which are I think in gtk-demo or the docs somewhere, but draw to the main window not border windows)
Some amount of work, but it would probably get the job done.
