The fringe indicators are tiny icons Emacs displays in the window fringe (on a graphic display) to indicate truncated or continued lines, buffer boundaries, overlay arrow, etc.
When this is non-
nil, Emacs displays a special glyph in the fringe of each empty line at the end of the buffer, on graphical displays. See Fringes. This variable is automatically buffer-local in every buffer.
This buffer-local variable controls how the buffer boundaries and window scrolling are indicated in the window fringes.
Emacs can indicate the buffer boundaries—that is, the first and last line in the buffer—with angle icons when they appear on the screen. In addition, Emacs can display an up-arrow in the fringe to show that there is text above the screen, and a down-arrow to show there is text below the screen.
There are three kinds of basic values:
- Don't display any of these fringe icons.
- Display the angle icons and arrows in the left fringe.
- Display the angle icons and arrows in the right fringe.
- any non-alist
- Display the angle icons in the left fringe and don't display the arrows.
Otherwise the value should be an alist that specifies which fringe indicators to display and where. Each element of the alist should have the form
). Here, indicator is one of
t(which covers all the icons not yet specified), while position is one of
((top . left) (t . right))places the top angle bitmap in left fringe, and the bottom angle bitmap as well as both arrow bitmaps in right fringe. To show the angle bitmaps in the left fringe, and no arrow bitmaps, use
((top . left) (bottom . left)).
This buffer-local variable specifies the mapping from logical fringe indicators to the actual bitmaps displayed in the window fringes.
These symbols identify the logical fringe indicators:
- Truncation and continuation line indicators:
- Buffer position indicators:
- Empty line indicator:
- Overlay arrow indicator:
- Unknown bitmap indicator:
The value is an alist where each element
)specifies the fringe bitmaps used to display a specific logical fringe indicator.
Here, indicator specifies the logical indicator type, and bitmaps is list of symbols
])which specifies the actual bitmap shown in the left or right fringe for the logical indicator.
The left and right symbols specify the bitmaps shown in the left and/or right fringe for the specific indicator. The left1 or right1 bitmaps are used only for the `bottom' and `top-bottom indicators when the last (only) line in has no final newline. Alternatively, bitmaps may be a single symbol which is used in both left and right fringes.
fringe-indicator-alisthas a buffer-local value, and there is no bitmap defined for a logical indicator, or the bitmap is
t, the corresponding value from the default value of
