| 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 | |
| 1213 | 40 * called from other places when an immediate screen update is needed. |
| 7 | 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. | |
