(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. (eval_form): Pass nil to new parameter of subst_vars. (do_output_line): New parameter, filter. Passed down to subst_vars. (do_output): New parameter, filter. Passed down to do_output_line. (match_files): Pass nil filter to subst_vars in cat directive. 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. --- Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'Makefile') diff --git a/Makefile b/Makefile index 7f842d5f..b555b657 100644 --- a/Makefile +++ b/Makefile @@ -37,7 +37,7 @@ CFLAGS := $(filter-out -Wmissing-prototypes -Wstrict-prototypes,$(CFLAGS)) endif OBJS := txr.o lex.yy.o y.tab.o match.o lib.o regex.o gc.o unwind.o stream.o -OBJS += hash.o utf8.o +OBJS += hash.o utf8.o filter.o PROG := ./txr -- cgit v1.2.3
