annotate src/mbyte.c @ 3549:f52d2ea0f81c v7.3.535
updated for version 7.3.535
Problem: Many #ifdefs for MB_MAXBYTES.
Solution: Also define MB_MAXBYTES without the +multi_byte feature. Fix
places where the buffer didn't include space for a NUL byte.

| 11 * mbyte.c: Code specifically for handling multi-byte characters. | |
| 12 * | |
| 13 * The encoding used in the core is set with 'encoding'. When 'encoding' is | |
| 14 * changed, the following four variables are set (for speed). | |
| 15 * Currently these types of character encodings are supported: | |
| 16 * | |
| 17 * "enc_dbcs" When non-zero it tells the type of double byte character | |
| 18 * encoding (Chinese, Korean, Japanese, etc.). | |
| 19 * The cell width on the display is equal to the number of | |
| 20 * bytes. (exception: DBCS_JPNU with first byte 0x8e) | |
| 21 * Recognizing the first or second byte is difficult, it | |
| 22 * requires checking a byte sequence from the start. | |
| 23 * "enc_utf8" When TRUE use Unicode characters in UTF-8 encoding. | |
| 24 * The cell width on the display needs to be determined from | |
| 25 * the character value. | |
| 26 * Recognizing bytes is easy: 0xxx.xxxx is a single-byte | |
| 27 * char, 10xx.xxxx is a trailing byte, 11xx.xxxx is a leading | |
| 28 * byte of a multi-byte character. | |

29 * To make things complicated, up to six composing characters |
| 7 | 30 * are allowed. These are drawn on top of the first char. |
| 31 * For most editing the sequence of bytes with composing | |
| 32 * characters included is considered to be one character. | |
| 33 * "enc_unicode" When 2 use 16-bit Unicode characters (or UTF-16). | |
| 34 * When 4 use 32-but Unicode characters. | |
| 35 * Internally characters are stored in UTF-8 encoding to | |
| 36 * avoid NUL bytes. Conversion happens when doing I/O. | |
| 37 * "enc_utf8" will also be TRUE. | |
| 38 * | |
| 39 * "has_mbyte" is set when "enc_dbcs" or "enc_utf8" is non-zero. | |
| 40 * | |
| 41 * If none of these is TRUE, 8-bit bytes are used for a character. The | |
| 42 * encoding isn't currently specified (TODO). | |
| 43 * | |
| 44 * 'encoding' specifies the encoding used in the core. This is in registers, | |
| 45 * text manipulation, buffers, etc. Conversion has to be done when characters | |
| 46 * in another encoding are received or send: | |
| 47 * | |
| 48 * clipboard | |
| 49 * ^ | |
| 50 * | (2) | |
| 51 * V | |
| 52 * +---------------+ | |
| 53 * (1) | | (3) | |
| 54 * keyboard ----->| core |-----> display | |
| 55 * | | | |
| 56 * +---------------+ | |
| 57 * ^ | |
| 58 * | (4) | |
| 59 * V | |
| 60 * file | |
| 61 * | |
| 62 * (1) Typed characters arrive in the current locale. Conversion is to be | |
| 63 * done when 'encoding' is different from 'termencoding'. | |
| 64 * (2) Text will be made available with the encoding specified with | |
| 65 * 'encoding'. If this is not sufficient, system-specific conversion | |
| 66 * might be required. | |
| 67 * (3) For the GUI the correct font must be selected, no conversion done. | |
| 68 * Otherwise, conversion is to be done when 'encoding' differs from | |
| 69 * 'termencoding'. (Different in the GTK+ 2 port -- 'termencoding' | |
| 70 * is always used for both input and output and must always be set to | |
| 71 * "utf-8". gui_mch_init() does this automatically.) | |
| 72 * (4) The encoding of the file is specified with 'fileencoding'. Conversion | |
| 73 * is to be done when it's different from 'encoding'. | |
| 74 * | |
| 75 * The viminfo file is a special case: Only text is converted, not file names. | |
| 76 * Vim scripts may contain an ":encoding" command. This has an effect for | |
| 77 * some commands, like ":menutrans" | |

| 4648 * if there was one, save the new preedit cursor offset, and put the new | |
| 4649 * string into the input buffer. | |
| 4650 * | |
| 4651 * TODO: The pragmatic "put into input buffer" approach used here has | |
| 4652 * several fundamental problems: | |
| 4653 * | |
| 4654 * - The characters in the preedit string are subject to remapping. | |
| 4655 * That's broken, only the finally committed string should be remapped. | |
| 4656 * | |
| 4657 * - There is a race condition involved: The retrieved value for the | |
| 4658 * current cursor position will be wrong if any unprocessed characters | |
| 4659 * are still queued in the input buffer. | |
| 4660 * | |
| 4661 * - Due to the lack of synchronization between the file buffer in memory | |
| 4662 * and any typed characters, it's practically impossible to implement the | |
| 4663 * "retrieve_surrounding" and "delete_surrounding" signals reliably. IM | |
| 4664 * modules for languages such as Thai are likely to rely on this feature | |
| 4665 * for proper operation. | |
| 4666 * | |
| 4667 * Conclusions: I think support for preediting needs to be moved to the | |
| 4668 * core parts of Vim. Ideally, until it has been committed, the preediting | |
| 4669 * string should only be displayed and not affect the buffer content at all. | |
| 4670 * The question how to deal with the synchronization issue still remains. | |
| 4671 * Circumventing the input buffer is probably not desirable. Anyway, I think | |
| 4672 * implementing "retrieve_surrounding" is the only hard problem. | |
| 4673 * | |
| 4674 * One way to solve all of this in a clean manner would be to queue all key | |
| 4675 * press/release events "as is" in the input buffer, and apply the IM filtering | |
| 4676 * at the receiving end of the queue. This, however, would have a rather large | |
| 4677 * impact on the code base. If there is an easy way to force processing of all | |
| 4678 * remaining input from within the "retrieve_surrounding" signal handler, this | |
| 4679 * might not be necessary. Gotta ask on vim-dev for opinions. | |
