60 * When writing messages to the screen, there are many different situations. | |
61 * A number of variables is used to remember the current state: | |
62 * msg_didany TRUE when messages were written since the last time the | |
63 * user reacted to a prompt. | |
64 * Reset: After hitting a key for the hit-return prompt, | |
65 * hitting <CR> for the command line or input(). | |
66 * Set: When any message is written to the screen. | |
67 * msg_didout TRUE when something was written to the current line. | |
68 * Reset: When advancing to the next line, when the current | |
69 * text can be overwritten. | |
70 * Set: When any message is written to the screen. | |
71 * msg_nowait No extra delay for the last drawn message. | |
72 * Used in normal_cmd() before the mode message is drawn. | |
73 * emsg_on_display There was an error message recently. Indicates that there | |
74 * should be a delay before redrawing. | |
75 * msg_scroll The next message should not overwrite the current one. | |
76 * msg_scrolled How many lines the screen has been scrolled (because of | |
77 * messages). Used in update_screen() to scroll the screen | |
78 * back. Incremented each time the screen scrolls a line. | |
79 * msg_scrolled_ign TRUE when msg_scrolled is non-zero and msg_puts_attr() | |
80 * writes something without scrolling should not make | |
81 * need_wait_return to be set. This is a hack to make ":ts" | |
82 * work without an extra prompt. | |
83 * lines_left Number of lines available for messages before the | |
3240 | 84 * more-prompt is to be given. -1 when not set. |
7 | 85 * need_wait_return TRUE when the hit-return prompt is needed. |
86 * Reset: After giving the hit-return prompt, when the user | |
87 * has answered some other prompt. | |
88 * Set: When the ruler or typeahead display is overwritten, | |
89 * scrolling the screen for some message. | |
90 * keep_msg Message to be displayed after redrawing the screen, in | |
91 * main_loop(). | |
92 * This is an allocated string or NULL when not used. | |
93 */ | |

272 | 4095 * This code was included to provide a portable vsnprintf() and snprintf(). |
715 | 4096 * Some systems may provide their own, but we always use this one for |
272 | 4097 * consistency. |
4098 * | |
4099 * This code is based on snprintf.c - a portable implementation of snprintf | |
4100 * by Mark Martinec <mark.martinec@ijs.si>, Version 2.2, 2000-10-06. | |
1189 | 4101 * Included with permission. It was heavily modified to fit in Vim. |
272 | 4102 * The original code, including useful comments, can be found here: |
4103 * http://www.ijs.si/software/snprintf/ | |
4104 * | |
4105 * This snprintf() only supports the following conversion specifiers: | |
4106 * s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below) | |
4107 * with flags: '-', '+', ' ', '0' and '#'. | |
4108 * An asterisk is supported for field width as well as precision. | |

6448 | 4122 * for the given input, excluding the trailing NUL. If this value |
715 | 4123 * is greater or equal to "str_m", not all characters from the result |
4124 * have been stored in str, output bytes beyond the ("str_m"-1) -th character | |
4125 * are discarded. If "str_m" is greater than zero it is guaranteed | |
