* 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.

* * eval.c (op_qquote_error, op_unquote_error): New static functions.Kaz Kylheku2011-12-041-31/+15
| | | | | | | | | | | | | (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.

(make_lazycons): Renamed to make_lazy_cons, relocated and turned into external function. (lazy_stream_func, lazy_stream_cons): Follow rename of make_lazycons. * lib.h (rplaca, rplacd, make_lazy_cons, lcons_fun): Declared. * txr.1: Stub sections created.
* * eval.c (uw_protect_s, return_s, return_from_s): New symbolKaz Kylheku2011-12-031-0/+6
| | | | | | | | | | | | | | variables. (op_unwind_protect, op_block, op_return, op_return_from): New static functions. (expand): Removed case for call, if, and, and or. These operators evaluate all their arguments, so the code walker can treat them as a function calls. Added case for block and return-from. (eval_init): New symbols interned. New operator functions registered in op_table. * txr.1: Blank sections added.
* * eval.c (eval_init): String and character functionsKaz Kylheku2011-12-031-2/+47
| | | | | | exposed as intrinsics. * txr.1: Blank sections created.
* * txr.1: Added stub sections for new functions.Kaz Kylheku2011-12-021-0/+17

* * 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.
