M-e and M-a also work better (I had problems in Latex with them). The line-number remains accurate, but you can use movement keys to scroll to the next displayed line without actually changing lines. This patch changes the redisplay engine to wrap on \s (i.e., whitespace) and now Longlines/Notepad-like wrapping is available everywhere. There is now a fourth flavor that kind of obsoletes Long Lines mode – Kim Storm’s word-wrap patch has landed in CVS (uh, I think early August or September 2008). is an informative article which compares and contrasts some of the above approaches. The default behavior of line-wrapping or truncating (#1) changes only the way your text appears, and Long Lines mode (#3) changes your text only temporarily. Of these three flavors, only Auto Fill mode actually changes your file (saved buffer). These are removed when you save the buffer to a file or copy its text for yanking elsewhere, so they are only for display purposes. Modes such as Long Lines wrap lines on word boundaries as you type, by inserting temporary line-ending characters. removing all line ends from a paragraph, currently (as of Emacs 24.3) no built-in function exists – see UnfillParagraph Instead of wrapping a single line around to the next window line, the line is divided into two separate lines, separated by a line ending. This behavior is called filling a paragraph – see AutoFillMode.īesides relying on this fill-as-you-type behavior, you can manually fill an existing paragraph with command ‘fill-paragraph’ ( ‘M-q’). When you type past a certain column ( option ‘fill-column’), Emacs inserts a line ending. Truncating lines does not alter your buffer text in any way – the displayed backslash character of line-wrapping and the dollar ( $) character of truncating are not part of the text (and so cannot be accessed). To prevent Emacs from wrapping lines in this way and instead appear to truncate lines that are longer than the window width, use TruncateLines. Mail read or written within Emacs can take advantage of FormatFlowedīy default, when a line extends past the width of the window, Emacs wraps it, either displaying a backslash (`\’) in the buffer or placing a bent arrow (↩) in the window fringe.VisualLineMode wrapping is essentially a display effect. Modes such as VisualLineMode wrap a line right before the window edge, but ultimately they do not alter the buffer text. ![]() Such “soft” wrapping is essentially a display effect. Modes such as VisualFillColumn (in concert with VisualLineMode) wrap a line after the last word before ‘fill-column’, but ultimately they do not alter the buffer text.Modes such as AutoFillMode insert a line ending after the last word that occurs before the value of option ‘fill-column’ (a column number).By default, Emacs wraps a line that reaches the window width, except at a word boundary.
