annotate src/message.c @ 5826:afb542ea210c v7.4.256
updated for version 7.4.256
Problem: Using systemlist() may cause a crash and does not handle NUL
characters properly.
Solution: Increase the reference count, allocate memory by length. (Yasuhiro
Matsumoto)

| 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. | |

| 95 * main_loop(). | |

| 4006 * This code was included to provide a portable vsnprintf() and snprintf(). | |
| 715 | 4007 * Some systems may provide their own, but we always use this one for |
| 272 | 4008 * consistency. |
| 4009 * | |
| 4010 * This code is based on snprintf.c - a portable implementation of snprintf | |
| 4011 * by Mark Martinec <mark.martinec@ijs.si>, Version 2.2, 2000-10-06. | |
| 1189 | 4012 * Included with permission. It was heavily modified to fit in Vim. |
| 272 | 4013 * The original code, including useful comments, can be found here: |
| 4014 * http://www.ijs.si/software/snprintf/ | |
| 4015 * | |
| 4016 * This snprintf() only supports the following conversion specifiers: | |
| 4017 * s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below) | |
| 4018 * with flags: '-', '+', ' ', '0' and '#'. | |
| 4019 * An asterisk is supported for field width as well as precision. | |
| 4020 * | |
| 1619 | 4021 * Limited support for floating point was added: 'f', 'e', 'E', 'g', 'G'. |
| 4022 * | |
| 272 | 4023 * Length modifiers 'h' (short int) and 'l' (long int) are supported. |
| 4024 * 'll' (long long int) is not supported. | |
| 4025 * | |
| 437 | 4026 * The locale is not used, the string is used as a byte string. This is only |
| 4027 * relevant for double-byte encodings where the second byte may be '%'. | |
| 4028 * | |
| 715 | 4029 * It is permitted for "str_m" to be zero, and it is permitted to specify NULL |
| 4030 * pointer for resulting string argument if "str_m" is zero (as per ISO C99). | |
| 272 | 4031 * |
| 4032 * The return value is the number of characters which would be generated | |
| 4033 * for the given input, excluding the trailing null. If this value | |
| 715 | 4034 * is greater or equal to "str_m", not all characters from the result |
| 4035 * have been stored in str, output bytes beyond the ("str_m"-1) -th character | |
| 4036 * are discarded. If "str_m" is greater than zero it is guaranteed | |
| 272 | 4037 * the resulting string will be null-terminated. |
| 4038 */ | |
| 4039 | |
| 4040 /* | |
| 4041 * When va_list is not supported we only define vim_snprintf(). | |
| 449 | 4042 * |
| 4043 * vim_vsnprintf() can be invoked with either "va_list" or a list of | |
| 482 | 4044 * "typval_T". When the latter is not used it must be NULL. |
