* fixparam: signed/unsigned warning from GNU C++.Kaz Kylheku2019-10-251-1/+1
| | | | | | | * lib.h (FIXPARAM_MAX): Switch constant to signed type. * lib.c (func_vm): Use num instead of unum on FIXPARAM_MAX, since we are making it signed.
* parser: use faster, unsafe nreverse.Kaz Kylheku2019-10-251-0/+1
| | | | | | | | | | * lib.c (us_nreverse): New function. * lib.h (us_nreverse): Declared. * parser.y (clauses_opt, n_exprs, r_exprs): Use us_nreverse instead of nreverse to rorder lists built in reverse into final shape.
* functions: provide accessors for basic properties.Kaz Kylheku2019-10-181-0/+3
| | | | | | | | | | | | | | * eval.c (eval_init): Register intrinsic functions fun-fixparam-count, fun-optparam-count, fun-variadic. * lib.c (get_param_counts): New static function. (fun_fixparam_count, fun_optparam_count, fun_variadic): New functions. * lib.h (fun_fixparam_count, fun_optparam_count, fun_variadic): Declared. * txr.1: Documented.
* vm: prevent overflow of fixparam field in function.Kaz Kylheku2019-10-171-2/+5
| | | | | | | | | | | | | Functions can only have 127 fixed parameters; some code ignores this when assigning to the bitfield. * lib.h (FIXPARAM_BITS, FIXPARAM_MAX): New preprocessor symbols. (struct func): Use FIXPARAM_BITS for defining fixparam and optargs bitfields instead of hard-coded 7. * lib.c (func_vm): Sanity check the fixparam and reqags parameters: 0 <= reqargs <= fixparam <= FIXPARAM_MAX.

* hash: use ucnum for hash values everywhere.Kaz Kylheku2019-10-121-1/+1
| | | | | | | | | | | | | | | | | | | One consequence of this is that we no longer pass negative values to vecref; that functon was protecting us from the consequences of this signed/unsigned mixup, at the cost of cyles. * hash.c (struct hash_ops): hash parameter in assoc_fun and acons_new_c_fun pointers changes from cnum to ucnum. (hash_assoc, hash_assql, hash_assq): hash parameter changes to ucnum. (hash_acons_new_c, hash_aconsql_new_c, hash_aconsq_new_c): Likewise. (gethash_c, gethash_e, remhash): Variable which captures the output of the hashing function is now ucnum instead of cnum. * lib.h (struct cons_hash_entry): Member hash changes from cnum to ucnum.
* safety: fix type tests that code can subvert.Kaz Kylheku2019-09-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes numerous instances of a safety hole which involves the type of a COBJ object being tested to be of a given class using logic that can be subverted by the definition of a like-named struct. Specifically logic like (typeof(obj) == hash_s) is broken, because if a struct type called hash is defined, then the test will yield true for instances of that struct type. Those instances can then be passed into code that only works on COBJ hashes, and relies on this test to reject invalid objects. * ffi.c (make_carray): Replace fragile test with strong one, using new cobjclassp function. * hash.c (hashp): Likewise. * lib.c (class_check): The expression used here for the type test moves into the new function cobjclassp and so is replaced by a call to that function. (cobjclassp): New function. * lib.h (cobjclassp): Declared. * rand.c (random_state_p): Replace fragile test using cobjclassp. * regex.c (char_set_compile): Replace fragile typeof tests for character type with is_chr. (reg_derivative, regexp): Replace fragile test with cobjclassp. * struct.c (struct_type_p): Replace fragile test with cobjclassp.
* New data type: tnode.Kaz Kylheku2019-09-221-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Binary search tree nodes are being added as a basic heap data type. The C type tag is TNOD, and the Lisp type is tnode. Binary search tree nodes have three elements: a key, a left child and a right child. The printed notation is #N(key left right). Quasiquoting is supported: ^#N(,foo ,bar) but not splicing. Because tnodes have three elements, they they fit into TXR's four-word heap cell, not requiring any additional memory allocation. These nodes are going to be the basis for a binary search tree container, which will use the scapegoat tree algorithm for maintaining balance. * tree.c, tree.h: New files. * Makefile (OBJS): Adding tree.o. * eval.c (expand_qquote_rec): Recurse through tnode cells, so unquotes work inside #N syntax. * gc.c (finalize): Add TNOD to no-op case in switch; tnodes don't require finalization. (mark_obj): Traverse tnode cell. * hash.c (equal_hash): Add TNOD case. * lib.c (tnode_s): New symbol variable. (seq_kind_tab): New entry for TNOD, mapping to SEQ_NOTSEQ. (code2type, equal): Handle TNOD. (obj_init): Initialize tnode_s variable. (obj_print_impl, populate_obj_hash): Handle TNOD. (init): Call tree_init function in tree.c. * lib.h (enum type, type_t): New enumeration TNOD. (struct tnod): New struct type. (union obj, obj_t): New union member tn of type struct tnod. (tnode_s): Declard. * parserc.c (circ_backpatch): Handle TNOD, so circular notation works through tnode cells. * parser.l (grammar): Recognize #N prefix, mapping to HASH_N token. * parser.y (HASH_N): New grammar terminal symbol. (tnode): New nonterminal symbol. (i_expr, n_expr): Add tnode cases to productions. (yybadtoken): Map HASH_N to "#N" string.
* All HAVE_* macros should be tested with #if, not #ifdef.Kaz Kylheku2019-09-121-1/+1
| | | | | | | | | | | | | | | | | * configure: In several config tests, test HAVE_SUPERLONG_T, HAVE_LONGLONG_T and HAVE_SYS_WAIT with #if. * lib.c: Test HAVE_GETENVIRONMENTSTRINGS with #if. * lib.h: Test HAVE_DOUBLE_INTPTR_T with #if. * mpi/mpi.c: Likewise. * mpi/mpi.h: Likewise. * socket.c: Test HAVE_GETADDRINFO with #if in three places. * stream.c: Test HAVE_SYS_WAIT and HAVE_SOCKETS with #if.
* structs: move SLOT_CACHE_SIZE macro.Kaz Kylheku2019-09-041-2/+0
| | | | | | | | | | Only struct.c refers to this symbol, and so only struct.c needs to be recompiled when someone experiments with different values. * lib.h (SLOT_CACHE_SIZE): Macro deleted here. * struct.c (SLOT_CACHE_SIZE): Macro moved here.
* New function: tailp.Kaz Kylheku2019-09-031-0/+1
| | | | | | | | | | * eval.c (eval_init): Register tailp intrinsic. * lib.c (tailp): New function. * lib.h (tailp): Declared. * txr.1: Documented.

* New function: intern-fb.Kaz Kylheku2019-08-201-0/+1
| | | | | | | | | | | | | | | To accompany find-symbol-fb, there is intern-fb, which is like intern, but searches the fallback list. * eval.c (eval_init): Register intern-fb intrinsic. * lib.c (intern_fallback_intrinsic): New function. Does defaulting and error checks, then calls intern_fallback, just like intern_intrinsic calls intern. * lib.h (intern_fallback_intrinsic): Declared. * txr.1: Documented.
* lib: streamline interning slightly.Kaz Kylheku2019-08-201-0/+1
| | | | | | | | | | | | | | | | | | | | | We get rid of some defaulting and error checks from interning. This saves a few cycles on startup in the large number of intern calls that are performed. * eval.c (eval_init): Wire the intern intrinsic to the new intern_intrinsic function rather than intern. * lib.c (intern): Remove package lookup and error check on str argument. (intern_intrinsic): New function, which has the package lookup and error check. (intern_fallback): Remove package lookup and error check. * lib.h (intern_intrinsic): Declared. * txr.c (txr_main): Fix one instance of an intern call that relies on defaulting of the second argument, by passing cur_package.
* new functions: find-symbol and find-symbol-fb.Kaz Kylheku2019-08-191-1/+2
| | | | | | | | | | | | | | | | | | Turns out, there is already a find_symbol in lib.c, completely unused. * eval.c (eval_init): Register find-symbol and find-symbol-fb intrinsics. * lib.c (find_symbol): Fix this hitherto unused function to do correct defaulting of the package argument and, to accept an additional argument specifying the not-found value. (find_symbol_fb): New function. * lib.c (find_symbol): Declaration updated. (find_symbol_fb): Declared. * txr.1: Documented.
* seq_iter: remove pointless one-member union.Kaz Kylheku2019-08-141-3/+1
| | | | | | | | * lib.h (struct seq_iter): union ul with just one member replaced by that member itself. * lib.c (seq_iter_get_vec, seq_iter_peek_vec, seq_iter_init): refer to it->len instead of it->ul.len.
* ffi: support flexible structures.Kaz Kylheku2019-07-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds support for working with foreign structures which use the C99 "flexible array member", or possibly the old "C struct hack". Some improvements are made in the FFI code the area of incomplete types and bitfields. * ffi.c (struct txr_ffi_type): New flag members incomplete and bitfield. (ffi_varray_dynsize): Check incomplete type flag rather than for zero size. (ffi_flex_dynsize, ffi_flex_alloc, ffi_flex_struct_in): New static functions. (ffi_struct_in): Call ffi_flex_struct_in when doing by-value semantics on a flexible structure, just before converting last member. This checks for the length method, calls it, and adjusts the last member object as documented. (ffi_struct_get): Likewise. (bitfield_syntax_p): Static function removed; there is a flag for this now in the type, so no need to parse its syntax. (make_ffi_type_pointer): Test bitfield flag rather than using bitfield_syntax_p. (make_ffi_type_struct): Take new argument indicating that the struct is flexible. Wire in appropriate virtual functions based on this flag, and set the type's incomplete flag accordingly. Check bitfield flag rather than using bitfield_syntax_p for detecting bitfield members. Calculate the size of flexible struct differently: it is the offset of the last member. (make_ffi_type_union): Test bitfield flag rather than using bitfield_syntax_p. (ffi_struct_compile): Renamed to ffi_membs_compile. (ffi_membs_compile): New pointer parameter for returning an indication whether the member list specifies a flexible struct. Test the incomplete flag of a member type rather than size being zero. (ffi_type_compile): Follow rename of ffi_struct_compile to ffi_membs_compile. Pass down the flag obtained from ffi_membs_compile into make_ffi_type_struct so that a flexible struct type is created when necessary. Disallow arrays of bitfields. Set bitfield flag on bitfield types. (ffi_init_types): Set incomplete flag on void type. (ffi_make_call_desc): Test for incomplete and bitfield types using new flags. (ffi_typedef, ffi_size, ffi_alignof): Test for bitfield type using new bitfield flag. (carray_elem_check): New static function. (carray_buf, carray_pun, carray_unum, carray_num): Use new carray_elem_check to check for bad array element type. This uses the incomplete flag rather than checking for zero size, and also disallows bitfields. * lib.h (length_s): Declared. * txr.1: Flexible structs documented in new section. Also section on incomplete types. Description of sizeof operator gives more detaild about incomplete types including flexible structs.
* list_collect: handle objects.Kaz Kylheku2019-06-251-0/+1
| | | | | | | | | * lib.c (list_collect): Handle sequence-like COBJ objects. We can add an item to using their respective replace functions. (replace_obj): Change to external linkage. * lib.h (replace_obj): Declared.

(seq_iter_init): Initialize new peek member of seq_iter structure. * lib.h (struct seq_iter): New member, peek. (seq_peek): New inline function. (seq_geti): Declared.
* lib: remove unused numeric macros.Kaz Kylheku2019-05-251-2/+0
| | | | * lib.h (maxint, minint): Remove unused macros.
* lib: more nuanced file access errors.Kaz Kylheku2019-05-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several new more specific exception types are derived from file-error and used. Error handlers can distinguish unexpected non-existence, unexpected existence and permission errors from each other and other errors. * lib.c (path_not_found_s, path_exists_s, path_permission_s): New symbol variables. (obj_init): New variables initialized. * lib.h (path_not_found_s, path_exists_s, path_permission_s): Declared. * parser.c (open_txr_file): Use new errno_to_file_error function to convert errno to exception symbol. * socket.c (open_sockfd): Likewise. * stream.c (open_directory, open_file, open_fileno, open_command, open_process, run, remove_path, rename_path): Likewise, and process-error is used in open_process and run instead of file-error for problems related to creating the process. * sysif.c (errno_to_file_error): New function. (mkdir_wrap, ensure_dir, chdir_wrap, getcwd_wrap, mknod_wrap, chmod_wrap, symlink_wrap, link_wrap, readlink_wrap, stat_impl, umask_wrap, ): Use errno_to_file_error to convert errno to exception symbol. (exec_wrap): Use process-error instead of file-error. * sysif.c (errno_to_file_error): Declared. * unwind.c (uw_init): Register path-not-found, path-exists and path-permission as subtypes of file-error. * txr.1: Documented.
* New function: window-mapdo.Kaz Kylheku2019-04-211-0/+1
| | | | | | | | | | | | | | | | * lib.c (enum wmap_op): New enum type. (window_map_list): Use enum wmap_op for last argument instead of Boolean flag. If the argument is WMAP_MAPDO, do not accumulate. (window_map_vec, window_map, window_mapped): Adjust to new enum argument. (window_mapdo): New function. * lib.h (window_mapdo): Declared. * eval.c (eval_init): window-mapdo intrinsic registered. * txr.1: Documented.
* Support max length and depth for object printing.Kaz Kylheku2019-04-181-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * hash.c (hash_print_op): Implement max length. * lib.c (lazy_str_put, out_lazy_str): Take struct strm_base * parameter and implement max length. (out_quasi_str_sym): Don't use obj_print_impl for symbol's name string; just put_string. The use of obj_print_impl causes symbols appearing as variables in quasiliterals to be truncated when max length is imposed. (out_quasi_str): Implement max length. (obj_print_impl): Implement max length and depth. Note that there is now always a non-null ctx pointer. (obj_print): Always set up context pointer for obj_print_impl. Context now has pointer to low-level stream structure, where we can access max_length and max_depth. It also carries the recursion depth. * lib.h (lazy_str_put): Declaration updated. * stream.c (strm_base_init): Add initializers for max_length and max_depth. (put_string): Pass stream structure to lazy_str_put. (set_max_length, set_max_depth): New functions. (stream_init): set-max-length and set-max-depth intrinsics registered. * stream.h (struct strm_ctx): New members depth and strm. (struct strm_base): New members max_length and max_depth. (set_max_length, set_max_depth): Declared. * txr.1: Documented.
* New function: cptr-size-hint.Kaz Kylheku2019-04-061-0/+1
| | | | | | | | | | * eval.c (eval_init): Register cptr-size-hint intrinsic. * lib.c (cptr_size_hint): New function. * lib.h (cptr_size_hint): Declared. * txr.1: Documented.
* New unchecked setter for function environment.Kaz Kylheku2019-03-141-0/+1
| | | | | | | * lib.c (us_func_set_env): New function: func_set_env without the type check. * lib.h (us_func_set_env): Declared.
* lazy conses: support state in car and cdr.Kaz Kylheku2019-03-131-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here we allow application code to take advantage of a trick already used internally. When a lazy cons cell is created, we can temporarily put state information into its car and cdr fields. When these fields are accessed normally, by the car and cdr function, the lazy cons' update function will be invoked, which will populate these fields. If we have a way for that function to retrieve the existing values of those fields, then the function can treat those fields as state information: it can retrieve the values into temporary local variables, overwrite the original values, and then propagate the state information into the car and cdr into the next lazy cons cell being added. Thus lazy list generation that needs two cells of state or less does not require the allocation of a context object. * eval.c (eval_init): make-lazy-cons becomes a three-argument function with two optional parameters. New functions lcons-car and lcons-cdr are registered. * lib.c (make_lazy_cons_pub): New function, wrapping make_lazy_cons_car_cdr with argument defaulting. (lcons_car, lcons_cdr): New functions. * lib.h (make_lazy_cons_pu, lcons_car, lcons_cdr): Declared. * txr.1: Updated doc of make-lazy-cons regarding new arguments. Documented lcons-car and lcons-cdr.

| | | | | | | | | | * lib.c (make_lazy_cons_car_cdr): New function. (lazy_where_func, lazy_where_hash_func, where): Use make_lazy_cons_car and the new make_lazy_cons_car_cdr instead of two-step construction and initialization with us_rplaca and us_rplacd. * lib.h (make_lazy_cons_car_cdr): Declared.
* lib: rename make_half_lazy_cons.Kaz Kylheku2019-03-121-1/+1
| | | | | | | | | | | * lib.h (make_half_lazy_cons): Renamed to make make_lazy_cons_car. * lib.c (rem_lazy_rec, make_half_lazy_cons): Follow rename. * hash.c (hash_keys_lazy, hash_keys, hash_values_lazy, hash_values, hash_pairs_lazy, hash_pairs, hash_alist_lazy, hash_alist): Follow rename.

(us_cons_bind): New macro. * eval.c (lazy_mapcar_func, lazy_mapcarv_func, range_func, range_star_func, generate_func, giterate_func, ginterate_func, expand_right_fun, repeat_infinite_func, repeat_times_func, pad_func): Use us_cons_bind, us_car, us_cdr, us_rplaca, us_rplacd and us_lazy_cons_func, which skip the type check. * lib.c (lazy_conses_func, lazy_appendv_func, rem_lazy_func, lazy_flatten_func, lazy_flatcar_fund, tuples_func, partition_by_func, partition_func, split_func, split_star_func, partition_star_func, lazy_interpose_fun, take_list_fun, take_while_list_fun, take_until_list_fun, lazy_where_has_func): Likewise.
* New sequence iterator object and functions.Kaz Kylheku2019-03-111-1/+4
| | | | | | | | | | | | | | | | | * eval.c (eval_init): Register seq-begin, seq-next and seq-reset. * lib.c (seq_iter_s): New symbol variable. (seq_iter_mark): New static function. (seq_iter_ops): New static structure. (seq_begin, seq_next, seq_reset): New functions. (obj_init): Intern seq-iter symbol, used as class name for iterators. * lib.h (seq_iter_s, seq_begin, seq_next, seq_reset): Declared. * txr.1: Documented.
* bracket: new function.Kaz Kylheku2019-02-241-0/+1
| | | | | | | | | | * eval.c (eval_init): Register bracket intrinsic. * lib.c (bracket): New function. * lib.h (bracket): Declared. * txr.1: Documented.
* Optimize hash operation with unsafe car/cdr.Kaz Kylheku2019-02-141-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The associative lists that make up the chains of a hash table are guaranteed to be made of conses. We can use unsafe versions of car, cdr, rplaca and rplacd to speed up hash operations. * eval.c (op_dohash): Use unsafe operations on hash cell. * filter.c (trie_compress, regex_from_trie): Likewise. * hash.c (hash_equal_op, hash_print_op, hash_mark, hash_grow, hash_assoc, hash_assql, copy_hash_chain, gethash, inhash, gethash_n, sethash, remhash, hash_next, maphash, do_weak_tables, group_by, group_reduce, hash_keys_lazy, hash_keys, hash_values_lazy, hash_values, hash_pairs_lazy, hash_pairs, hash_alist_lazy, hash_uni, hash_diff, hash_symdiff, hash_isec, hash_subset, hash_update, hash_update_1, hash_revget): Likewise. * lib.c (us_rplaca, us_rplacd): New functions.

* Framework for iterating over sequences.Kaz Kylheku2019-02-131-0/+15
| | | | | | | | | | | | | | | | This has been needed for a while. While we have seq_info for classifying sequences to nicely dispatch code into various cases, those cases duplicate code. The code base could benefit from generic traversal. * lib.c (seq_iter_get_nil, seq_iter_get_list, seq_iter_get_vec, set_iter_get_hash): New static functions. (seq_iter_rewind, seq_iter_init): New functions. * lib.h (struct seq_iter, seq_iter_t): New struct type and its typedef name. (seq_iter_init, seq_iter_rewind): Declared.
