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 and
29 * ScreenLinesC[][] is not used. When the character occupies two display
30 * cells the next byte in ScreenLines[] is 0.
31 * ScreenLinesC[][] contain up to 'maxcombine' composing characters
32 * (drawn on top of the first character). There is 0 after the last one used.
33 * ScreenLines2[] is only used for euc-jp to store the second byte if the
34 * first byte is 0x8e (single-width character).
36 * The screen_*() functions write to the screen and handle updating
39 * update_screen() is the function that updates all windows and status lines.
40 * It is called form the main loop when must_redraw is non-zero. It may be
41 * called from other places when an immediate screen update is needed.
43 * The part of the buffer that is displayed in a window is set with:
44 * - w_topline (first buffer line in window)
45 * - w_topfill (filler line above the first line)
46 * - w_leftcol (leftmost window cell in window),
47 * - w_skipcol (skipped window cells of first line)
49 * Commands that only move the cursor around in a window, do not need to take
50 * action to update the display. The main loop will check if w_topline is
51 * valid and update it (scroll the window) when needed.
53 * Commands that scroll a window change w_topline and must call
54 * check_cursor() to move the cursor into the visible part of the window, and
55 * call redraw_later(VALID) to have the window displayed by update_screen()
58 * Commands that change text in the buffer must call changed_bytes() or
59 * changed_lines() to mark the area that changed and will require updating
60 * later. The main loop will call update_screen(), which will update each
61 * window that shows the changed buffer. This assumes text above the change
62 * can remain displayed as it is. Text after the change may need updating for
63 * scrolling, folding and syntax highlighting.
65 * Commands that change how a window is displayed (e.g., setting 'list') or
66 * invalidate the contents of a window in another way (e.g., change fold
67 * settings), must call redraw_later(NOT_VALID) to have the whole window
68 * redisplayed by update_screen() later.
70 * Commands that change how a buffer is displayed (e.g., setting 'tabstop')
71 * must call redraw_curbuf_later(NOT_VALID) to have all the windows for the
72 * buffer redisplayed by update_screen() later.
74 * Commands that change highlighting and possibly cause a scroll too must call
75 * redraw_later(SOME_VALID) to update the whole window but still use scrolling
76 * to avoid redrawing everything. But the length of displayed lines must not
77 * change, use NOT_VALID then.
79 * Commands that move the window position must call redraw_later(NOT_VALID).
80 * TODO: should minimize redrawing by scrolling when possible.
82 * Commands that change everything (e.g., resizing the screen) must call
83 * redraw_all_later(NOT_VALID) or redraw_all_later(CLEAR).
85 * Things that are handled indirectly:
86 * - When messages scroll the screen up, msg_scrolled will be set and
87 * update_screen() called to redraw.
93 * The attributes that are actually active for writing to the screen.
95 static int screen_attr
= 0;
98 * Positioning the cursor is reduced by remembering the last position.
99 * Mostly used by windgoto() and screen_char().
