59 * When writing messages to the screen, there are many different situations. | |
60 * A number of variables is used to remember the current state: | |
61 * msg_didany TRUE when messages were written since the last time the | |
62 * user reacted to a prompt. | |
63 * Reset: After hitting a key for the hit-return prompt, | |
64 * hitting <CR> for the command line or input(). | |
65 * Set: When any message is written to the screen. | |
66 * msg_didout TRUE when something was written to the current line. | |
67 * Reset: When advancing to the next line, when the current | |
68 * text can be overwritten. | |
69 * Set: When any message is written to the screen. | |
70 * msg_nowait No extra delay for the last drawn message. | |
71 * Used in normal_cmd() before the mode message is drawn. | |
72 * emsg_on_display There was an error message recently. Indicates that there | |
73 * should be a delay before redrawing. | |
74 * msg_scroll The next message should not overwrite the current one. | |
75 * msg_scrolled How many lines the screen has been scrolled (because of | |
76 * messages). Used in update_screen() to scroll the screen | |
77 * back. Incremented each time the screen scrolls a line. | |
78 * msg_scrolled_ign TRUE when msg_scrolled is non-zero and msg_puts_attr() | |
79 * writes something without scrolling should not make | |
80 * need_wait_return to be set. This is a hack to make ":ts" | |
81 * work without an extra prompt. | |
82 * lines_left Number of lines available for messages before the | |
3240 | 83 * more-prompt is to be given. -1 when not set. |
7 | 84 * need_wait_return TRUE when the hit-return prompt is needed. |
85 * Reset: After giving the hit-return prompt, when the user | |
86 * has answered some other prompt. | |
87 * Set: When the ruler or typeahead display is overwritten, | |
88 * scrolling the screen for some message. | |
89 * keep_msg Message to be displayed after redrawing the screen, in | |
90 * main_loop(). | |
91 * This is an allocated string or NULL when not used. | |
92 */ | |
