Bug 1060: Use libtre for regexp searches. When the user tells ELinks to search for a regexp, ELinks 0.11.0 passes the regexp to regcomp() and the formatted document to regexec(), both in the terminal charset. This works OK for unibyte ASCII-compatible charsets because the regexp metacharacters are all in the ASCII range. And ELinks 0.11.0 doesn't support multibyte or ASCII-incompatible (e.g. EBCDIC) charsets in terminals, so it is no big deal if regexp searches fail in such locales. ELinks 0.12pre1 attempts to support UTF-8 as the terminal charset if CONFIG_UTF8 is defined. Then, struct search contains unicode_val_T c rather than unsigned char c, and get_srch() and add_srch_chr() together save UTF-32 values there if the terminal charset is UTF-8. In plain-text searches, is_in_range_plain() compares those values directly if the search is case sensitive, or folds them to lower case if the search is case insensitive: with towlower() if the terminal charset is UTF-8, or with tolower() otherwise. In regexp searches however, get_search_region_from_search_nodes() still truncates all values to 8 bits in order to generate the string that search_for_pattern() then passes to regexec(). In UTF-8 locales, regexec() expects this string to be in UTF-8 and can't make sense of the truncated characters. There is also a possible conflict in regcomp() if the locale is UTF-8 but the terminal charset is not, or vice versa. Rejected ways of fixing the charset mismatches: * When the terminal charset is UTF-8, recode the formatted document from UTF-32 to UTF-8 for regexp searching. This would work if the terminal and the locale both use UTF-8, or if both use unibyte ASCII-compatible charsets, but not if only one of them uses UTF-8. * Convert both the regexp and the formatted document to the charset of the locale, as that is what regcomp() and regexec() expect. ELinks would have to somehow keep track of which bytes in the converted string correspond to which characters in the document; not entirely trivial because convert_string() can replace a single unconvertible character with a string of ASCII characters. If ELinks were eventually changed to use iconv() for unrecognized charsets, such tracking would become even harder. * Temporarily switch to a locale that uses the charset of the terminal. Unfortunately, it seems there is no portable way to construct a name for such a locale. It is also possible that no suitable locale is available; especially on Windows, whose C library defines MB_LEN_MAX as 2 and thus cannot support UTF-8 locales. Instead, this commit makes ELinks do the regexp matching with regwcomp and regwexec from the TRE library. This way, ELinks can losslessly recode both the pattern and the document to Unicode and rely on the regexp code in TRE decoding them properly, regardless of locale. There are some possible problems though: 1. ELinks stores strings as UTF-32 in arrays of unicode_val_T, but TRE uses wchar_t instead. If wchar_t is UTF-16, as it is on Microsoft Windows, then TRE will misdecode the strings. It wouldn't be too hard to make ELinks convert to UTF-16 in this case, but (a) TRE doesn't currently support UTF-16 either, and it seems possible that wchar_t-independent UTF-32 interfaces will be added to TRE; and (b) there seems to be little interest on using ELinks on Windows anyway. 2. The Citrus Project apparently wanted BSD to use a locale-dependent wchar_t: e.g. UTF-32 in some locales and an ISO 2022 derivative in others. Regexp searches in ELinks now do not support the latter.
