11 * screen.c: code for displaying on the screen
|
|
12 *
|
|
13 * Output to the screen (console, terminal emulator or GUI window) is minimized
|
|
14 * by remembering what is already on the screen, and only updating the parts
|
|
15 * that changed.
|
|
16 *
|
|
17 * ScreenLines[off] Contains a copy of the whole screen, as it is currently
|
|
18 * displayed (excluding text written by external commands).
|
|
19 * ScreenAttrs[off] Contains the associated attributes.
|
|
20 * LineOffset[row] Contains the offset into ScreenLines*[] and ScreenAttrs[]
|
|
21 * for each line.
|
|
22 * LineWraps[row] Flag for each line whether it wraps to the next line.
|
|
23 *
|
|
24 * For double-byte characters, two consecutive bytes in ScreenLines[] can form
|
|
25 * one character which occupies two display cells.
|
|
26 * For UTF-8 a multi-byte character is converted to Unicode and stored in
|
|
27 * ScreenLinesUC[]. ScreenLines[] contains the first byte only. For an ASCII
|
|
28 * character without composing chars ScreenLinesUC[] will be 0. When the
|
|
29 * character occupies two display cells the next byte in ScreenLines[] is 0.
|
714
|
30 * ScreenLinesC[][] contain up to 'maxcombine' composing characters
|
7
|
31 * (drawn on top of the first character). They are 0 when not used.
|
|
32 * ScreenLines2[] is only used for euc-jp to store the second byte if the
|
|
33 * first byte is 0x8e (single-width character).
|
|
34 *
|
|
35 * The screen_*() functions write to the screen and handle updating
|
|
36 * ScreenLines[].
|
|
37 *
|
|
38 * update_screen() is the function that updates all windows and status lines.
|
|
39 * It is called form the main loop when must_redraw is non-zero. It may be
|
|
40 * called from other places when an immediated screen update is needed.
|
|
41 *
|
|
42 * The part of the buffer that is displayed in a window is set with:
|
|
43 * - w_topline (first buffer line in window)
|
|
44 * - w_topfill (filler line above the first line)
|
|
45 * - w_leftcol (leftmost window cell in window),
|
|
46 * - w_skipcol (skipped window cells of first line)
|
|
47 *
|
|
48 * Commands that only move the cursor around in a window, do not need to take
|
|
49 * action to update the display. The main loop will check if w_topline is
|
|
50 * valid and update it (scroll the window) when needed.
|
|
51 *
|
|
52 * Commands that scroll a window change w_topline and must call
|
|
53 * check_cursor() to move the cursor into the visible part of the window, and
|
|
54 * call redraw_later(VALID) to have the window displayed by update_screen()
|
|
55 * later.
|
|
56 *
|
|
57 * Commands that change text in the buffer must call changed_bytes() or
|
|
58 * changed_lines() to mark the area that changed and will require updating
|
|
59 * later. The main loop will call update_screen(), which will update each
|
|
60 * window that shows the changed buffer. This assumes text above the change
|
|
61 * can remain displayed as it is. Text after the change may need updating for
|
|
62 * scrolling, folding and syntax highlighting.
|
|
63 *
|
|
64 * Commands that change how a window is displayed (e.g., setting 'list') or
|
|
65 * invalidate the contents of a window in another way (e.g., change fold
|
|
66 * settings), must call redraw_later(NOT_VALID) to have the whole window
|
|
67 * redisplayed by update_screen() later.
|
|
68 *
|
|
69 * Commands that change how a buffer is displayed (e.g., setting 'tabstop')
|
|
70 * must call redraw_curbuf_later(NOT_VALID) to have all the windows for the
|
|
71 * buffer redisplayed by update_screen() later.
|
|
72 *
|
743
|
73 * Commands that change highlighting and possibly cause a scroll too must call
|
|
74 * redraw_later(SOME_VALID) to update the whole window but still use scrolling
|
|
75 * to avoid redrawing everything. But the length of displayed lines must not
|
|
76 * change, use NOT_VALID then.
|
|
77 *
|
7
|
78 * Commands that move the window position must call redraw_later(NOT_VALID).
|
|
79 * TODO: should minimize redrawing by scrolling when possible.
|
|
80 *
|
|
81 * Commands that change everything (e.g., resizing the screen) must call
|
|
82 * redraw_all_later(NOT_VALID) or redraw_all_later(CLEAR).
|
|
83 *
|
|
84 * Things that are handled indirectly:
|
|
85 * - When messages scroll the screen up, msg_scrolled will be set and
|
|
86 * update_screen() called to redraw.
