/*--------------------------------------------------------------------------- match.c The match() routine recursively compares a string to a "pattern" (regular expression), returning TRUE if a match is found or FALSE if not. This version is specifically for use with unzip.c: as did the previous match() routines from SEA and J. Kercheval, it leaves the case (upper, lower, or mixed) of the string alone, but converts any uppercase characters in the pattern to lowercase if indicated by the global var pInfo->lcflag (which is to say, string is assumed to have been converted to lowercase already, if such was necessary). GRR: reversed order of text, pattern in matche() (now same as match()); added ignore_case/ic flags, Case() macro. PK: replaced matche() with recmatch() from Zip, modified to have an ignore_case argument; replaced test frame with simpler one. --------------------------------------------------------------------------- matchw.c : A modified version of match.c with Unicode matching.

In the pattern: `*' matches any sequence of characters (zero or more) `?' matches any character [SET] matches any character in the specified set, [!SET] or [^SET] matches any character not in the specified set. A set is composed of characters or ranges; a range looks like ``character hyphen character'' (as in 0-9 or A-Z). [0-9a-zA-Z_] is the minimal set of characters allowed in the [..] pattern construct. Other characters are allowed (ie. 8 bit characters) if your system will support them. To suppress the special syntactic significance of any of ``[]*?!^-\'', in- side or outside a [..] construct and match the character exactly, precede it with a ``\'' (backslash). Note that "*.*" and "*." are treated specially under MS-DOS if DOSWILD is defined. See the DOSWILD section below for an explanation. ---------------------------------------------------------------------------*/ #include #include #include #ifdef WCD_UNINORM # include /* part of libunistring */ #endif #include "wcd.h" #include "display.h" #include "finddirs.h" #include "matchw.h" /* define ToLower() in here (for Unix, define ToLower * to be macro (using isupper());
