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 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 ...
Line continuation – escapes a newline to continue a statement on the next line Some languages define a special character as a terminator while some, called line-oriented , rely on the newline . Typically, a line-oriented language includes a line continuation feature whereas other languages have no need for line continuation since newline is ...
The transmission control characters were intended to structure a data stream, and to manage re-transmission or graceful failure, as needed, in the face of transmission errors. The start of heading (SOH) character was to mark a non-data section of a data stream—the part of a stream containing addresses and other housekeeping data.
# If you need to add newlines and carriage returns, they need to be escaped using ('\n') and ('\r') respectively. # You can also optionally escape tabs with ('\t') for readability purposes. valueWithEscapes = This is a newline \n and a carriage return \r and a tab \t. # You can also use Unicode escape characters (maximum of four hexadecimal ...
In C and many derivative programming languages, a string escape sequence is a series of two or more characters, starting with a backslash \. [3]Note that in C a backslash immediately followed by a newline does not constitute an escape sequence, but splices physical source lines into logical ones in the second translation phase, whereas string escape sequences are converted in the fifth ...
Header fields are colon-separated key-value pairs in clear-text string format, terminated by a carriage return (CR) and line feed (LF) character sequence. The end of the header section is indicated by an empty field line, resulting in the transmission of two consecutive CR-LF pairs.
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
