Hi. I have some questions about vim_iswordc() and vim_iswordp().
[1] I recognize that we can use unicode character as an argument of vim_iswordc (and vim_iswordc_buf). If so, I think that the following must be satisfied; Is this correct? premise: * 'encoding' is utf8 * "c" is int, unicode character (U+NNNNNNNN) * "p" is (char_u *), utf8 sequence of "c" (e.g. c == 0x100 <=> p == "\xC4\x80") then: vim_iswordc(c) == vim_iswordp(p) is TRUE [2] If [1] is correct, it is a problem that there is a character such that vim_iswordc(c) != vim_iswordp(p) with specific 'iskeyword'. when c == 0xA0, p == "\xC2\xA0", and 'iskeyword' includes 160 (e.g. iskeyword=@,48-57,_,128-167,224-235 (default on windows)) then: vim_iswordc(c) == 1, but vim_iswordp(p) == 0. bacause: In vim_iswordc_buf(); https://github.com/vim/vim/blob/342156637/src/charset.c#L911 c == 0xA0 < 0x100 https://github.com/vim/vim/blob/342156637/src/charset.c#L911 c > 0 and c < 0x100, and c is in buf->b_chartab (GET_CHARTAB(buf, c) != 0). Thus, vim_iswordc_buf(c, buf) is TRUE. In vim_iswordp_buf(); https://github.com/vim/vim/blob/342156637/src/charset.c#L921 has_mbyte is TRUE and MB_BYTE2LEN(*p) == 2. (*p == 0xC2) https://github.com/vim/vim/blob/342156637/src/charset.c#L922 https://github.com/vim/vim/blob/342156637/src/mbyte.c#L898 calls mb_get_class(p) -> utf_class(utf_ptr2char(p)). utf_ptr2char(p) == 0xA0, is equal to c, so utf_class(0xA0). https://github.com/vim/vim/blob/342156637/src/mbyte.c#L2781 c < 0x100 and c == 0xa0, then return 0. Thus, vim_iswordp_buf(p, buf) is FALSE. [3] This is not mush to do with above; It appears that * vim_iswordp_buf() should use mb_get_class_buf() * vim_iswordp() should return vim_iswordp_buf(p, curbuf) https://gist.github.com/ichizok/1be6efa8364777cf167003e2c5676d8f Thank you. - Ozaki Kiichi -- -- You received this message from the "vim_dev" maillist.
