When doing ^]], vile's using a function checks only the character class, and stops when a character isn't an "identifier": int screen_to_ident(char *buf, size_t bufn) { int rc = FALSE; CHARTYPE mask = vl_ident; int whole_line = adjust_chartype(&mask); TRACE((T_CALLED "screen_to_ident\n")); rc = read_by_regex(buf, bufn, b_val_rexp(curbp, VAL_IDENTIFIER_EXPR), whole_line); if (rc == FALSE) rc = read_by_ctype(buf, bufn, mask, whole_line); returnCode(rc); } :show-printable shows that it's not (by default) an "id" character: 45 - - - - - - prn pun - - path - arg - nsp - tmp sh 46 . - - - - - prn pun - - path - arg - nsp - tmp sh 47 / - - - - - prn pun - - path - - - nsp - tmp sh 48 0 - - num - - prn - - id path - arg - nsp qid tmp sh 49 1 - - num - - prn - - id path - arg - nsp qid tmp sh You could change that with set-char-class id=[.] 45 - - - - - - prn pun - - path - arg - nsp - tmp sh 46 . - - - - - prn pun - id path - arg - nsp - tmp sh 47 / - - - - - prn pun - - path - - - nsp - tmp sh 48 0 - - num - - prn - - id path - arg - nsp qid tmp sh 49 1 - - num - - prn - - id path - arg - nsp qid tmp sh > seen with vile version 9.8o for darwin14.3.0. > > thank you > > joerg > > PS: I also presume, there is a small `ctags' bug here. the search pattern > probably should backslash-protect the period in order to actually only match > `disp.array' verbatim rather than > disp{any-single-character}array, no? otherwise one might jump to the wrong > tag/file/position. hmm - I think it's correct, since "magic" is normally set. -- Thomas E.
