* * eval.c (eval_intrinsic): We don't need to make an environmentKaz Kylheku2014-02-221-10/+7
| | | | | | | | | | | | | | | | | | here if the env parameter is nil. The low level environment lookup functions already handle nil. (do_eval): Do not type check the env argument for the ENV type. (expand_forms, expand): No need to default a missing menv to a blank environment; just use nil. (macro_form_p): Take menv parameter and switch to lookup_mac from gethash. (macroexpand_1, macroexpand): Use the environment parameter by using lookup_mac rather than gethash. (eval_init): Fix registration of macro_form_p to reflect new optional argument. * txr.1: Documented optional environment parameters in macro-form-p, macroexpand-1 and macroexpand. Documented macrolet.
* Implemented macrolet.Kaz Kylheku2014-02-221-3/+45
| | | | | | | | | * eval.c (macrolet_s): New variable. (lookup_mac, expand_macrolet): New static functions. (expand): Recognize and expand macrolet form. use lookup_mac to resolve macros rather than gethash, since we have lexical macros now. (eval_init): Intern macrolet symbol.

| | | | | | | | | | | | | | | | | environment down through the expander call hierarchy. * eval.c (expand_opt_params, expand_params, expand_tree_cases, expand_tree_case, expand_forms, val expand_cond_pairs, val expand_place, expand_qquote, expand_vars, expand_quasi, expand_op, expand_catch_clause, expand_catch, expand): All expanders get new parameter, menv. expand_forms and expand handle a nil value of menv. (eval_intrinsic): Pass nil macro environment to expand. (eval_init): Update intrinsic registration for expand. * eval.h (expand, expand_forms): Declarations updated. * parser.y (expand_meta): Gets macro env parameter. (elem, o_elem, exprs, expr): Pass nil to expand_forms and expand_meta.
* Replacing uses of the eq function which are used only as C booleans,Kaz Kylheku2014-02-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | with just using the == operator. Removing cobj_equal_op since it's indistinguishable from eq. Streamlining missingp and null_or_missing_p. * eval.c (transform_op): eq to ==. (c_var_ops): cobj_equal_op to eq. * filter.c (trie_compress, trie_lookup_feed_char, filter_string_tree, html_hex_continue, html_dec_continue): eq to ==. * hash.c (hash_iter_ops): cobj_equal to eq. * lib.c (countq, getplist, getplist_f, search_str_tree, posq): eq to ==. (cobj_equal_op): Function removed. * lib.h (cobj_equal_op): Declaration removed. (missingp): Becomes a simple macro that yields a C boolean instead of t/nil val, because it's only used that way. (null_or_missing_p): Becomes inline function returning int. * match.c (v_output): eq to ==. * rand.c (random_state_ops): cobj_equal_op to eq. * regex.c (char_set_obj_ops, regex_obj_ops): cobj_equal_op to eq. (reg_derivative): Silly if3 expression replaced by null. (regexp): Redundant if2 expression wrapped around eq removed. * stream.c (null_ops, stdio_ops, tail_ops, pipe_ops, string_in_ops, byte_in_ops, string_out_ops, strlist_out_ops, dir_ops, cat_stream_ops): cobj_equal_op to eq. * syslog.c (syslog_strm_ops): cobj_equal_op to eq.
* The C function nullp is being renamed to null, and the rarelyKaz Kylheku2014-02-221-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | used global variable null which holds a symbol becomes null_s. A new macro called nilp is added that more efficiently checks whether an object is nil, producing a C boolean value rather than t or nil. Most of the uses of nullp in the codebase just become the more streamlined nilp. * debug.c (show_bindings): nullp to nilp * eval.c (lookup_var, lookup_var_l, lookup_fun, lookup_sym_lisp1, do_eval, expand_qquote, expand_quasi, expand_op): nullp to nilp. (op_modplace): nullp to null. (eval_init): Update registration of null and not from C function nullp to null. * filter.c (trie_compress, html_hex_continue): nullp to nil. (filter_string_tree): null to null_s. * hash.c (hash_next): nullp to nilp. * lib.c (null): Variable renamed to null_s. (code2type): null to null_s. (lazy_flatten_scan, chainv, lazy_str, lazy_str_force_upto, obj_print, obj_pprint): nullp to nilp. (obj_init): null to null_s; nullp to null. * lib.h (null): declaration changed to null_s.

* Implementing special variables with local overriding.Kaz Kylheku2014-02-211-43/+162
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All predefined globals become special. * eval.c (special, with_saved_vars_s): New global variables. (mark_special, special_p): New functions. (bindings_helper): Takes new argument, include_specials. Now processes the special colon syntax for denoting special variables, setting up their values, taking care to observe whether the binding is parallel or sequential. (op_let, op_for): Pass new argument to bindings_helper. (op_each): Pass new argument to bindings_helper with a value of it, and deal with the colon annotations that emerge in the bindings. (op_defvar, regvar): Mark symbol as special. (op_with_saved_vars): New static function. (expand_vars): Takes new argument, returns a cons. Detects special variables among the vars and produces the colon syntax. (expand_catch_clause): Bugfix: this was using expand_vars on a parameter list. Now properly uses expand_params. (expand_save_specials): New static function. (expand): For the operators that are binding constructs, handle the new form of expand_vars which returns information about special variables. If specials occur, then generate the with-saved-vars form around the expansion which will save and restore their values. The expansion of vars done by expand_vars, together with the run-time actions of bindings_helper, do the rest. Speaking of which, the new with-saved-vars operator form is now expanded here too. (eval_init): Protect new variables special and with_saved_vars_s. Initialize special with new hash table. Store new interned symbol in with_saved_vars_s. Register op_with_save_vars in op_table. * txr.1: Documented specials.
* * eval.c (subst_vars): Change throwing of query_error_sKaz Kylheku2014-02-211-2/+1
| | | | | | to eval_error call. This is a leftover from when this was cloned from its counterpart in match.c. However, I can't think of a way this call can ever be reached.

| | | | | | | | | | | | | | | | (eval_init): Register env and env_hash functions. Register prog_args and prog_args_full as *args* and *full-args*. * lib.c (timegm_hack): Invalidate env_list, after mucking with the environment via setenv and unsetenv. * txr.c (prog_args_full, prog_args): New global variables. (txr_main): Command-line processing converted to use TXR's library. Populates prog_args_full and prog_args. * txr.h (prog_args_full, prog_args): Declared. * txr.1: Documented *args*, *full-args*, env and env-hash.
* The mode argument in some stream-opening functions becomes optional.Kaz Kylheku2014-02-181-3/+3
| | | | | | | | | | * eval.c (eval_init): Change registration for open_file, open_tail and open_command. * stream.c (open_file, open_tail, open_command): mode_str argument defaulted. * txr.1: Updated.

* * eval.c (eval_init): Register gensym function as the gensymKaz Kylheku2014-02-171-1/+2
| | | | | | | | | | | | | | intrinsic, rather than gensymv. Register gensym_counter as *gensym-counter*. * lib.c (gensym): Handle missing prefix argument by defaulting the prefix to "g". (gensymv): Function removed. * lib.h (gensymv): Declaration removed. * txr.1: Fixed omission: missing documentation for gensym. Documented *gensym-counter*.

* * eval.c (op_tree_case): Removed superfluous handling ofKaz Kylheku2014-02-161-8/+5
| | | | | | | | nil parameter list; this is correctly handled by bind_macro_params. Added support for the colon symbol as an indication that the case is declined. * txr.1: Updated.
* New destructuring operators.Kaz Kylheku2014-02-161-11/+117
| | | | | | | | | | | | | | | | | * eval.c (tree_case_s, tree_bind_s): New symbol variables. (bind_macro_params): Bugfix: inappropriate exception thrown when atom matched against parameter list. Bugfix: nil being returned when atom matches empty parameter list. Added support for a new convention: if loose_p is the colon keyword, then exceptions are not thrown for destructuring mismatches; nil is returned instad. (op_tree_case, expand_tree_cases, expand_tree_case, op_tree_bind): New static functions. (expand): Handle tree_case_s and tree_bind_s. (eval_init): Intern tree-case and tree-bind symbols. Register the corresponding operator functions op_tree_case and op_tree_bind under these symbols in op_table. * txr.1: Documented tree-case and tree-bind operators.
* * eval.c (bind_macro_params): Bugfix: enforce mismatch onKaz Kylheku2014-02-161-0/+5

* In the spirit of the previous hack, here is another hack toKaz Kylheku2014-02-161-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | alleviate a long-standing pain: when an exception happens in TXR's library somewhere, the program dies without leaving a clue about what code was being evaluated when that happened. What we can do is have the evaluator publish the most recent compound form it has processed by stashing it in a variable. Then when an unhandled exception occurs, we can peek at that and try to pull out source location info. * eval.c (last_form_evaled): New variable. (do_eval): When evaluating a compound form, stash it in last_form_evaled. (eval_init): Protect last_form_evaled from gc. * eval.h (last_form_evaled): Declared. (eval_error_s): Existing variable declared. * unwind.c: Has to include "eval.h" for the above variable and "parser.h" for the source_loc function. (uw_throw): When an exception is unhandled, if last_form_evaled has source info, add it to the diagnostic. But not if the exception is eval-error; because errors from the evaluators already have the info.
* Nice idea: how about a function which walks the tree structure andKaz Kylheku2014-02-161-2/+1
| | | | | | | | | | | | | | | | back-fills some missing source code location info. We apply this to macro expansions. If some error occurs in expanded code, this way it is referenced to the line where the macro *call* occurs. Not only is this better than nothing, it may be better than tracing it to the macro definition. Ideally, we would have both places: ("the error is in the code expanded from this macro, at this site"). * eval.c (expand): Use rlcp_tree to back-fill source info in macro expansion by taking it from the unexpanded form. * parser.h (rlcp_tree): Declared. * parser.y (rlcp_tree): New function.
* Bugfixes: not propagating source loc info in quasiliterals.Kaz Kylheku2014-02-161-3/+2
| | | | | | * eval.c (expand_quasi): Add some rlcp's here. * parser.y (o_var, quasi_items, o_elems_transform): Likewise.

* * eval.c (bind_macro_params): Bugfix: the :whole parameter mustKaz Kylheku2014-02-151-1/+4
| | | | | | | | | capture the entire form, not just the arguments. (expand): Apply rlcp to the result of macro expansion, if it has not set up source code location. (eval_init): Register rlcp as intrinsic. * txr.1: Start of macro documentation. Documented rlcp.
* First cut at implementation of macros.Kaz Kylheku2014-02-151-7/+207
| | | | | | | | | | | | | | | * eval.c (top_mb, defmacro_s, macro_time_s, whole_k, env_k): New global variables. (expand_params): Recurse to handle macro parameter lists too. (bind_macro_params, op_defmacro, expand_macro): New static functions. (expand): Evaluate defmacro forms and macro-time forms at expansion time. Recognize and expand macros (albeit not yet with proper lexical scoping: local bindings are not able to shadow a macro). (eval_init): Protect top_mb from GC and initialize it. Intern new symbols defmacro, macro-time, and :whole. Register defmacro operator in op_table. * match.h (env_k): Added declaration for existing external variable.
* Bugfix: parameters of defun were not being treated by expander.Kaz Kylheku2014-02-151-8/+56
| | | | | | | | | | | They need to be since they can contain evaluable initforms for default arguments. Ditto with lambda; lambda parameters were being treated using expand_vars, which is not appropriate. * eval.c (expand_opt_params, expand_params): New static functions. (expand_vars): Bugfix: added some missing rlcp's to propagate line number info. (expand): Move lambda to separate case, and expand its params

| | | | | | | | | | | | | | | | | | | | | | | | | | | that return the new or old cons cell rather than a pointer to its cdr field. * eval.c (transform_op): use of acons_new_l replaced with acons_new_c. * hash.c (struct hash): acons_new_l_fun member replaced with acons_new_c_fun. (make_hash, make_similar_hash): initialize acons_new_l_fun member using either acons_new_c or aconsql_new_c. (gethash_l): function becomes an inline in hash.h. (gethash_c): new function, based on gethash_l. (inhash, gethash_n): updated w.r.t struct hash change. * hash.h (gethash_c): declared. (gethash_l): becomes an inline wrapper for gethash_c. * lib.c (acons_new_l, aconsql_new_l): functions removed. (acons_new_c, aconsql_new_c): new functions. (obj_init): use gethash_c and rplacd instead of gethash_l and set. * lib.h (acons_new_l, aconsql_new_l): declarations removed. (acons_new_c, aconsql_new_c): declared.

| | | | | | | | | | | | | | | | | | | | | for more flexible joining of data from the hash tables. * eval.c (eval_init): Remove hash_guni and hash_gisec. Change registration for hash_uni and hash_isec to three arguments with one optional. * hash.c (hash_uni): Third parameter introduced, join_func. The default behavior changes: in the two argument case, clashing keys prefer the value from hash1 rather than hash2. For this reason, we now iterate over hash2 first, then hash1. (hash_guni): Removed. (hash_isec): Third parameter introduced, join_func. (hash_gisec): Removed. * hash.h (hash_uni, hash_isec): Declarations updated. (hash_guni, hash_gisec): Delarations removed. * txr.1: Documentation updated.
* * eval.c (eval_init): Register hash_guni and hash_gisec as intrinsics.Kaz Kylheku2014-02-141-0/+2
| | | | | | | | | | | * hash.c (hash_guni, hash_gisec): New functions. (hash_isec): Bugfix: since gethash was naively used, keys in hash2 associated with the value nil were erroneously omitted from the intersection. * hash.h (hash_guni, hash_gisec): Declared. * txr.1: Documented new functions.
