If a variable is followed by a mixture + of text and regular expressions, that whole mixture is + considered to follow the variable and used for matching. + + The earlier semantics change whereby a single unescaped + space denotes the regular expression / +/ broke the + simple case @a word. It caused the @a to be followed + not by the text " word" but by just the regular expression + element. + + With this change @a word means that a is followed by + the regex / +/ and "word". + + * match.c (text_s): New symbol variable. + (h_text): New function. + (syms_init): Initialize new symbol variable. + (dir_tables_init): Hook h_text into horizontal directives table. + + * match.h (text_s): Declared. + + * parser.y (text, texts): New nonterminals. + (elem): TEXT, SPACE and regex are now handled under texts + grammar production. All texts are run together and produce + an item which looks like (text items ...). + + * txr.1, RELNOTES: Updated. + + * txr.c (remove_hash_bang_line): Updated to find #! buried + in (text ...) syntax. + 2011-11-22 Kaz Kylheku <kaz@kylheku.com> * configure: Fix environ test case for C++. |
