3 * VIM - Vi IMproved by Bram Moolenaar
5 * Do ":help uganda" in Vim to read copying and usage conditions.
6 * Do ":help credits" in Vim to see a list of people who contributed.
7 * See README.txt for an overview of the Vim source code.
11 * screen.c: code for displaying on the screen
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
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[]
22 * LineWraps[row] Flag for each line whether it wraps to the next line.
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.
30 * ScreenLinesC[][] contain up to 'maxcombine' composing characters
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).
35 * The screen_*() functions write to the screen and handle updating
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 immediate screen update is needed.
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)
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.
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()
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.
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.
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.
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.
78 * Commands that move the window position must call redraw_later(NOT_VALID).
79 * TODO: should minimize redrawing by scrolling when possible.
81 * Commands that change everything (e.g., resizing the screen) must call
82 * redraw_all_later(NOT_VALID) or redraw_all_later(CLEAR).
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.
92 * The attributes that are actually active for writing to the screen.
94 static int screen_attr
= 0;
97 * Positioning the cursor is reduced by remembering the last position.
98 * Mostly used by windgoto() and screen_char().
