* Version 049txr-049Kaz Kylheku2011-12-191-2/+2
| | | | | | | | | | * txr.c (version): Bumped. * txr.1: Bumped version and set date. * configure (txr_ver): Bumped. * RELNOTES: Updated.
* * eval.c (bindings_helper): Fix format arguments.Kaz Kylheku2011-12-181-0/+9
| | | | | | | | | | | | | | | | | (eval_init): Registered new functions: symbol-function, func-get-form, func-get-env, functionp, interp-fun-p. * lib.c (nappend2, getplist_f, improper_plist_to_alist): tail variable renamed to avoid clash in macro. (func_get_form, func_get_env, interp_fun_p): New functions. * lib.h (func_get_form, func_get_env, interp_fun_p): Declared. (list_collect): Fix macro not to throw error, but handle the case. * match.c (vars_to_bindings, extract_bindings): tail variable renamed to avoid clash in macro. * txr.1: Documentation stubs.
* * eval.c (eval_init): not added as synonym for null.Kaz Kylheku2011-12-151-3/+313
| | | | | | | | | | | | | | | | | | | | | | | | | | * lib.c (copy_list): Use list_collect_append rather than list_collect_terminate. (append2, appendv): Simplified using new list_collect_append. (nappend2): Simplified using new list_collect_nconc. * lib.h (list_collect): Added check for accidental usage of list_collect after list_append, since PTAIL has different semantics. (list_collect_nconc, list_collect_append): Semantics fixed so that append collecting works more like the Common Lisp append function, allowing trailing atoms or a lone atom. The meaning of PTAIL is changed, however. Now PTAIL actually tracks the head of the most recently appended segment. Each append operation has to first traverse the previously added piece to get to the end. (list_collect_terminate): Macro removed. * match.c (v_gather): Removed useless use of list_collect_terminate. * parser.y: Some headers added that are needed by list_collect. * txr.1: Documented append, list, atom, null, not, consp, make-lazy-cons, lcons-fun, listp, proper-listp, length-list, mapcar, mappend, and apply.
* @# comments are becoming obsolescent. @# commentsKaz Kylheku2011-12-141-6/+22

(hash_grow, make_hash): No need to call vec_set_length. * lib.c (equal, vecref, vec_push, length_vec, list_vector, obj_print, obj_pprint): vec_fill to vec_length name change. (vector): Argument now represents actual length, not just allocated size. (vec_get_fill): Function removed; did exactly the same thing as length_vec. (vec_set_fill): Function renamed to vec_set_length. (vector_list): Allocate a 0 length vector initially. * lib.h (enum vecindex): member changes name from vec_fill to vec_length. (vector): Parameter name changed. (vec_set_fill): Redeclared. (vec_get_fill): Declaration removed. * txr.1: Doc stubs updated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | warning. (eval_init): New functions registered: typeof and vector functions, as well as length_list. * lib.c (length): Function renamed to length_list, because it is list specific. (length_vec, size_vec, vector_list): New functions. (length): New function, generic over lists, vectors and strings. * lib.h (length_list, length_vec, size_vec, vector_list): Declared. * match.c (h_var, h_fun, robust_length, v_deffilter, v_fun): Use length_list instead of length. * parser.l: Introduced # token. * parser.y (vector): New nonterminal.

(lit_char_helper): Use length_list instead of length. * stream.c (string_in_get_line): Bugfix: this was using the wrong length function: length was being applied to a string. The genericity of length makes that correct now, but changing to length_str anyway. * txr.1: Blank sections created for functions. Vector syntax documented.

| | | | | | | | | | | | | (expand_qquote): Bugfix: missing case added to handle directly quoted quasiquote. (eval_init): Error-catching pseudo-operators registered in op_table. * parser.y (force_regular_quotes): New function.

| | | | | | | | | | | | | | | * eval.c (eval_init): New intrinsic functions. * lib.c (rplaca, rplacd, lcons_fun): New functions. (make_lazycons): Renamed to make_lazy_cons, relocated and turned into external function.

* * parser.y (list): unquote and splice actions look inside theKaz Kylheku2011-12-021-0/+26
| | | | | | | | | | argument form. If an unquote or splice are applied to a quoted form, its quote becomes a regular quote. This behavior is necessary to make ,',form work in nested quotes, otherwise the ' is a quasiquote which captures the comma in ,form, reducing ,',form to ,form. * txr.1: Documented this special behavior.

* Semantics change. If a variable is followed by a mixtureKaz Kylheku2011-11-231-18/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* * match.c (search_form): Bugfix: we must search to one characterKaz Kylheku2011-11-221-0/+17
| | | | | | | | | | position after the end of the line, otherwise we can never match @(eol). (h_eol): Bugfix: do not return t, but the line length. * txr.1: Warn users about @var@(bind ...) pitfall. * RELNOTES: Updated.
* Version 042Kaz Kylheku2011-11-201-2/+2
| | | | | | | | * txr.c (version): Bumped. * txr.1: Bumped version and set date. * configure (txr_ver): Bumped.
* Relaxing :vars in collect/coll a little bit.Kaz Kylheku2011-11-201-0/+2
| | | | | | | | | | | | | * match.c (h_coll, v_collect): Only throw an error about missing required variables if the collect iteration collected some new variables. This allows strict collects with :vars to have some cases which explicitly match and skip unwanted material, without binding variables. Also, print all missing variables in the diagnostic. * txr.1: Mention this special exception. * RELNOTES: Updated.
* Bug #34866Kaz Kylheku2011-11-191-1/+7
| | | | | | | * match.c (h_skip): Bugfix. Return the length of the line if the skip is to the end of line, not the value t. * txr.1: Clarify that @var@(skip)text is useless.
* * match.c (v_deffilter): Even better. Just evaluateKaz Kylheku2011-11-191-4/+11
| | | | | | | | the arguments individually. Now @(deffilter a b ..) is possible where these evaluate to suitable lists of strings. * txr.1: Documented.
* deffilter grows in power: it can take quasistrings.Kaz Kylheku2011-11-191-3/+6
| | | | | | | | | | | | | | | | * lib.c (cdr_f): New global variable. (funcall1, funcall2, funcall3, funcall4): Fix unterminated arguments in uw_throwf call by using uw_throw instead. (do_or): New static function. (orf): New function. (obj_init): gc_protect and initialize cdr_f. * lib.h (cdr_f, orf): Declared. * match.c (v_deffilter): Treat the table as forms to be evaluated which must reduce to strings, rather than literal strings. * txr.1: Documented.
* Task #11598.Kaz Kylheku2011-11-171-2/+36
| | | | | | | | | | | | | * match.c (resolve_k): New keyword symbol variable. (h_parallel, v_parallel): Implement :resolve keyword in @(some) directive. (syms_init): New symbol variable initialized. * parser.l: Allow (some) to have argument material. * parser.y (some_clause, elem): SOME syntax adjusted. * txr.1: Documented new :resolve keyword in @(some).
* * match.c (h_fun, v_fun): Bugfix! copy_list should be used for copyingKaz Kylheku2011-11-171-2/+7
| | | | | | | | | | | | | | the bindings, not copy_alist. Otherwise functions cannot destructively update a binding, which is useless. We want a function not to manipulate the binding list, but to be able to manipulate the contents of bindings. (match_files_ctx): Declaration moved ahead of match_line. (v_fun): Forward declaration added. (match_line): Allow vertical functions to be called from a horizontal context, in a limited way. * txr.1: Mention the possibility of a call from a horizontal context falling back on a vertical function.
* Allow directives after variable to be a kind of negative match.Kaz Kylheku2011-11-161-39/+119
| | | | | | | | | | | | | | | * match.c (search_form): bugfix: return correct match extent. * parser.y: Adjusting associativity and precedence of directives, IDENT, and grouping tokens once again. This is so that a var followed by a directive will turn into one elem, rather than the var being reduced to an elem first. * txr.1: Revised documentation to mroe clearly define the concept of a negative match, broken into subsections. Some sections belonging to syntax were moved to an appropriate location. Subsections added to description of form syntax. Explanation of directive-driven syntax.
* Variable matches can span over function calls.Kaz Kylheku2011-11-161-10/+16
| | | | | | | | | | | | Function calls following variables have searching semantics. * match.c (ml_specline_pos, search_form): New static functions. (h_var): Handle functions and regexes in a common way. * parser.y: Adjusted precedence of IDENT and ( so that @var@(func) are parsed into a single var element. * txr.1: Documented.
* Changing read syntax for character literals, because we are going toKaz Kylheku2011-11-151-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | need the single quote in the Lisp way for suppressing evaluation, eventually. I'm going with a Scheme-compatible syntax for character literals. It has a richer repertoire of standard character names than Common Lisp, and has a x convention for coding characters in hex. * lib.c (obj_print): Print characters in a Scheme-like way. * parser.h (end_of_char): New function declared. * parser.l (grammar): Implement rules for #\ syntax, with involving new HASH_BACKSLASH token. (end_of_regex): Enhancement: added check that end_of_regex is called in correct state, like the one in end_of_char. (end_of_char): New function. * parser.y (repeat_rep_helper, o_elems_transform, define_transform, lit_char_helper): Functions changed to static. (rl): Function moved down, past the grammar section. (HASH_BACKSLASH): New terminal symbol. (chrlit): Grammar redesigned. (char_from_name): New function. * txr.1: Character syntax documented.
* * txr.1: Document -l/--lisp-bindings.Kaz Kylheku2011-11-101-0/+3
