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

3975 * This code was included to provide a portable vsnprintf() and snprintf(). | |
715 | 3976 * Some systems may provide their own, but we always use this one for |
272 | 3977 * consistency. |
3978 * | |
3979 * This code is based on snprintf.c - a portable implementation of snprintf | |
3980 * by Mark Martinec <mark.martinec@ijs.si>, Version 2.2, 2000-10-06. | |
1189 | 3981 * Included with permission. It was heavily modified to fit in Vim. |
272 | 3982 * The original code, including useful comments, can be found here: |
3983 * http://www.ijs.si/software/snprintf/ | |
3984 * | |
3985 * This snprintf() only supports the following conversion specifiers: | |
3986 * s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below) | |
3987 * with flags: '-', '+', ' ', '0' and '#'. | |
3988 * An asterisk is supported for field width as well as precision. | |
3989 * | |
1619 | 3990 * Limited support for floating point was added: 'f', 'e', 'E', 'g', 'G'. |
3991 * | |
272 | 3992 * Length modifiers 'h' (short int) and 'l' (long int) are supported. |
3993 * 'll' (long long int) is not supported. | |
3994 * | |
437 | 3995 * The locale is not used, the string is used as a byte string. This is only |
3996 * relevant for double-byte encodings where the second byte may be '%'. | |
3997 * | |
715 | 3998 * It is permitted for "str_m" to be zero, and it is permitted to specify NULL |
3999 * pointer for resulting string argument if "str_m" is zero (as per ISO C99). | |
272 | 4000 * |
4001 * The return value is the number of characters which would be generated | |
4002 * for the given input, excluding the trailing null. If this value | |
715 | 4003 * is greater or equal to "str_m", not all characters from the result |
4004 * have been stored in str, output bytes beyond the ("str_m"-1) -th character | |
4005 * are discarded. If "str_m" is greater than zero it is guaranteed | |
272 | 4006 * the resulting string will be null-terminated. |
4007 */ | |
4008 | |
4009 /* | |
4010 * When va_list is not supported we only define vim_snprintf(). | |
449 | 4011 * |
4012 * vim_vsnprintf() can be invoked with either "va_list" or a list of | |
482 | 4013 * "typval_T". When the latter is not used it must be NULL. |
