| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * filter.c, filter.h: New files. * Makefile (OBJS): filter.o added. * gc.c (mark_obj): Mark new alloc field of string objets. * hash.c (struct hash): New member, userdata. (hash_mark): Mark new userdata member of hash. (make_hash): Initialize userdata. (get_hash_userdata, set_hash_userdata, hashp): New functions. * hash.h (get_hash_userdata, set_hash_userdata, hashp): New functions declared. * lib.c (getplist, string_extend, cobjp): New functions. (string_own, string, string_utf8): Initialize new alloc field to nil. (mkstring, mkustring): Initialize new alloc field to actual size. (length_str): When length is computed and cached, also compute and cache alloc. (init): Call filter_init. * lib.h (string string): New member, alloc. (num_fast): Macro converted to inline function. (getplist, string_extend, cobjp): New functions declared. * match.c (match_line): Follows change of modifier s-exp syntax. (format_field): New parameter, filter. New modifier syntax parsed. Filter retrieved, and applied. (subst_vars): New parameter, filter. Filter is either applied in this function or passed to format_field, as needed.

Output directive refactored to parse keywords, extract the filter and pass down to do_output. * parser.y (regex): Generate (sys:regex regex syntax ...) instead of (regex syntax ...). (elem, expr): Updated w.r.t. regex syntax change. (var): Cases '{' IDENT regex '}' and '{' IDENT NUMBER '}' are removed. new syntax '{' IDENT exprs '}' to handle these more generally and allow for keywords. * txr.1: Updated.
