Variable: fringe-indicator-alist

fringe-indicator-alist is a buffer-local variable defined in buffer.c.

Documentation

Mapping from logical to physical fringe indicator bitmaps.

The value is an alist where each element (INDICATOR . BITMAPS) specifies the fringe bitmaps used to display a specific logical fringe indicator.

INDICATOR specifies the logical indicator type which is one of the following symbols: truncation , continuation, overlay-arrow, top, bottom, top-bottom, up, down, empty-line', or unknown.

BITMAPS is a list of symbols (LEFT RIGHT [LEFT1 RIGHT1]) which specifies the actual bitmap shown in the left or right fringe for the logical indicator. LEFT and RIGHT are 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 has no final newline. BITMAPS may also be a single symbol which is used in both left and right fringes.
