Re: Confusing naming of fringe i C-code

[Richard Stallman]

    So far, I've come across several different names for the fringes:

    `fringe' is primarily used on user visible symbols,

    `bitmap' is used without explicit reference to the fringe, e.g. 
bitmap_type, x_draw_bitmap, ...   
    This isn't wrong, but it would be clearer to use fringe_bitmap_type,
    x_draw_fringe_bitmap, etc.

The name bitmap_type seems reasonable, but x_draw_bitmap should be
renamed to x_draw_fringe_bitmap.

    `bitmap area' is used in several comments, as well as in 
BITMAP_AREA_FACE_ID (= fringe face)

It would be good to rename that, too.

    `flags area' seems to be the favourite term throughout the code, e.g.
    FRAME_FLAGS_AREA_WIDTH, FRAME_X_RIGHT_FLAGS_AREA_WIDTH, flags_areas_extra, 
...

Is "flags area" in fact a synonym for "fringe"?  If so, it would be good
to rename these names too.

    And then there are the mixed forms FRAME_FLAGS_BITMAP_WIDTH and 
FRAME_FLAGS_BITMAP_HEIGHT.

Those names refer to the size of the bitmaps that are drawn in the
fringe, so they should be left unchanged.


Would you like to do it?
