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 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 ...
The request/status line and headers must all end with <CR><LF> (that is, a carriage return followed by a line feed). The empty line must consist of only <CR><LF> and no other whitespace . The "optional HTTP message body data" is what this article defines.
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 ...
The 1901 Murray code added the carriage return (CR) and line feed (LF), and other versions of the Baudot code included other control characters. The bell character (BEL), which rang a bell to alert operators, was also an early teletype control character. Some control characters have also been called "format effectors".
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 ...
Lua discards the first newline (if present) that directly follows the opening tag. Perl. Block comments in Perl are considered part of the documentation, and are given the name Plain Old Documentation (POD). Technically, Perl does not have a convention for including block comments in source code, but POD is routinely used as a workaround. PHP
