For line in text_area_value.split('\n'): # do something with line
or if you want a specific number (3 in this example - which is the 4th line, counting the "human" way):
lines = text_area_value.split.

Hello,
I have an array of bytes (say byte[] data), which contains text with custom line delimeters, for example: "\r\n" (CRLF "\x0D\x0A"), "\r", "\n", "\x0D\x0A\x0D" or even "@".
At the moment I'm going to use the following solution:

Adjust tw to your needs..
Why don't you just "J" the lines after you select them?
If you don't like "J" as depesz suggested then do
:set tw=9999
Then do 'gq'.

$ python -c "for r in range(10): print 'rob'"
this works fine. However, if I import a module before the for loop, I get a syntax error:
$ python -c "import sys; for r in range(10): print 'rob'" File...

I want to iterate over cin, line by line, addressing each line as a std::string. Which is better:

or
for (string line; getline(cin, line); ) { // process line }
? What is the normal way to do...

Awk '{ if ((NR-1) %4 ==0) print}'

Replace 4 by whatever value you want of course. .
Yes | cat -n | head -10 | awk 'NR % 4 == 1' 1 y 5 y 9 y
That is, your answer is " awk 'NR % 4 == 1' " .

I'm parsing a large file in Perl line-by-line (terminated by \n), but when I reach a certain keyword, say "TARGET", I need to grab all the lines between TARGET and the next completely empty line.
So, given a segment of a file:
Line 1
Line 2
Line 3

I have a multi-line string literal that I want to do an operation on each line, like so.

Like the others said:
inputString.split('\n'....
For line in split(inputString, "\n"): doStuff()
inputString.splitlines()
Will give you an array with each item, the splilines() function is designed to split each line into an array element.

Say I have a super long line in the VIM editor (say around 300+ characters). How would I break that up into multiple lines so that the word boundaries roughly break at 80 characters?

Then hitting q and CR will break the line up into chunks on the word boundary.
Which says:
start a 0th position of line, move to 80th char to the right, go to beginning of next word for that char.

In vim when my cursor is on the first line I can press:
100dd
to delete the first 100 lines.
But how do I delete all lines except the last 100 lines?
