The form feed character is sometimes used in plain text files of source code as a delimiter for a page break, or as marker for sections of code. Some editors, in particular emacs and vi, have built-in commands to page up/down on the form feed character. This convention is predominantly used in Lisp code, and is also seen in C and Python source ...
So the newline option can also be stated at the start of the pattern using one of the following: (*LF) Newline is a linefeed character. Corresponding linebreaks can be matched with \n. (*CR) Newline is a carriage return. Corresponding linebreaks can be matched with \r. (*CRLF) Newline/linebreak
This code generates "page C‑2" just like the plain code "page C-2", but prevents a line break at the hyphen. However, like , the use of ‑ instead of "-" renders the source text harder to read and edit. Don't use it unless it is really necessary to avoid a line break.
The concepts of carriage return (CR) and line feed (LF) are closely associated and can be considered either separately or together. In the physical media of typewriters and printers, two axes of motion, "down" and "across", are needed to create a new line on the page. Although the design of a machine (typewriter or printer) must consider them ...
Technically, Perl does not have a convention for including block comments in source code, but POD is routinely used as a workaround. PHP. PHP supports standard C/C++ style comments, but supports Perl style as well. Python. The use of the triple-quotes to comment-out lines of source, does not actually form a comment. [19]
Touchmaster Five with carriage return lever at left. Originally, the term "carriage return" referred to a mechanism or lever on a typewriter.For machines where the type element was fixed and the paper held in a moving carriage, this lever was on the left attached to the moving carriage, and operated after typing a line of text to cause the carriage to return to the far right so the type ...
Carriage return (CR) is represented by $, and line feeds (LF) with a -; both had to be sent in turn to return the cursor to the start of the line, CRLF. Sixel also includes a rudimentary form of compression, using run-length encoding (RLE).
Records are typically separated by a line feed, as is typical for Unix platforms, or a carriage return and line feed, as is typical for Microsoft platforms. Some programs may expect the latter. The de-facto specification [ 9 ] specifies that records are separated by an EOL , but does not specify any specific newline .
