* New function: delcons.Kaz Kylheku2021-09-021-0/+71
| | | | | | | | | | | | * eval.c (eval_init): Register delcons intrinsic. * lib.[ch] (delcons): New function. * tests/010/cons.tl: New file. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* load: new *load-hooks* feature.Kaz Kylheku2021-09-021-0/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | *load-hooks* lets a .txr, .tl or .tlo file specify actions to be taken when the loading of that file completes, whether normally or via an exception. They are also honored by process exit. For instance, with this, we can have a Lisp file that behaves like a script which cleans up after itself (e.g. removing temporary files) even if it is not run as a stand-alone program, but invoked via (load ...). Because it's not a stand-alone program, it cannot simply use the at-exit-call mechanism. The unwind-protect operator could be used, but it's inconvenient because it protects a single form. The *load-hooks* feature in effect protects all the top level forms of a load, similarly to unwind-protect. Also, unwind-protect does not guard against a process exit. (However, *load-hooks* does not guard against an abnormal exit, only normal termination). * eval.c (load_hooks_s): New symbol variable. (run_load_hooks): New function. (run_load_hooks_atexit): New static function. (load): bind *load-hooks* to nil around load. Implement the hooks processing via run_load_hooks, taking care to pass the load-time dynamic environment that has already been undone. (eval_init): Initialize load_hooks_s and register the *load-hooks* variable. Register run_load_hooks_atexit with atexit, so the current value of *load-hooks* is processed on process exit. * eval.h (load_hooks_s, run_load_hooks): Declared. * match.c (v_load): Similar changes as in load. * txr.c (txr_main): Run the load hooks with run_load_hooks immediately after processing the .txr or .tl file, before entering the listener. * tests/019/load-hook.tl: New directory and file * tests/load-hook.tl: New file. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * configure: configure test for mmap depositing HAVE_MMAP into config.h. * ffi.c (struct carray): Subject to HAVE_MMAP, new mm_len member which keeps track of the size of an underlying mapping so that we can unmap it, as well as peform operations like msync on it. (make_carray): Initialize mm_len to 0.

| | | | * txr.1: Fix cond to codn.
* sub: allow generic iterables.Kaz Kylheku2021-08-221-0/+39
| | | | | | | | | | | | | | | | In this patch we allow the s in (sub s from to) and [s from..to] to be any iterable. * lib.c (iter_dynamic, sub_iter): New static function. (generic_funcall): Handle all objects via the sequence case: ref, sub and all that. Unfortunately, we lose some error handling at the level of the sub function. But we allow any iterable to be passed through to sub. (sub): Handle default case through sub_iter. * tests/012/iter.tl: New cases. * txr.1: Documented.
* iter-begin: allow iterator argument.Kaz Kylheku2021-08-221-0/+11
| | | | | | | | * lib.c (seq_iter_init_with_info): Allow the iterated object to be an iterator, in which case a copy of the iterator is set up. * txr.1: Documented.
* iter-begin: string range support.Kaz Kylheku2021-08-221-1/+52
| | | | | | | | | | | | | | Ranges like "AAA".."ZZZ" are now possible. * lib.c (seq_iter_get_range_str, seq_iter_peek_range_str, seq_iter_get_rev_range_str): New static functions. (seq_iter_init_with_info): Support string ranges via above new functions. Range direction test is now done with less and equal rather than lt and gt. * tests/012/iter.tl: New file. * txr.1: Documented.
* matcher: rename error-throwing macros.Kaz Kylheku2021-08-191-8/+8
| | | | | | | | | | | | | | | * stdlib/match.tl (must-match): Renamed to just match. It's just when-match without the "when". (must-match-case): Renamed to match-ecase, consistent with the case -> ecase naming scheme. * lisplib.c (match_set_entries): Names updated here. * tests/011/patmatch.tl: Test cases updated. * txr.1: Names updated here. * stdlib/doc-syms.tl: Updated.
* New ecase macros.Kaz Kylheku2021-08-181-0/+72
| | | | | | | | | | | | | | | | | | | | Even prior to discovering the recent defect in deffi, which was caused by a missing case in caseql, combined with poor testing, I was already thinking about adding ecase macros. The introduction of must-match and must-match-case also shows my motivation. That deffi bug convinced me to take action and implement these. * eval.c (case_error_s) New symbol variable. (me_ecase): New static function. (eval_init): Register new intrinsic macros ecaseq, ecaseql, ecasequal, ecaseq*, ecaseql* and ecasequal*. Intern case-error and initialize case_error_s. * txr.1: Documented. Also updated Exception Hierarchy diagram with match-error and case-error. * stdlib/doc-syms.tl: Updated.
* doc: fix reference to nonexistent ffi-call-desc.Kaz Kylheku2021-08-171-1/+1
| | | | * txr.1: ffi-call-desc should be ffi-make-call-desc.
* getaddrinfo: implement canonname.Kaz Kylheku2021-08-151-2/+25
| | | | | | | | | | | | | | | | Paul A. Patience noted that the canonname_s variable is not used in the C code. This indicates that the AI_CANONNAME functionality of getaddrinfo isn't implemented. Let's do that. * stdlib/socket.tl (sockaddr): New slot, canonname. (addrinfo): Default canonname to nil, not 0, since it is a string that may be absent. * socket.c (getaddrinfo_wrap): If the first address object has a non-null ai_canonname and it was requested via the flags, then stick that name into every returned structure. * txr.1: Documented.
* doc: improve.Paul A. Patience2021-08-141-129/+136
| | | | | | | | | | | | * RELNOTES: Fix various minor issues and stylistic issues. * configure: Remove repeated word and add missing word. * txr.1: Fix various minor, not-so-minor and stylistic issues. In particular, struct-from-args was misspelled in the .mets line and open-subprocess was missing from the .coNP line. * stdlib/doc-syms.tl: Updated.
* matcher: new must-match and must-match-case macros.Kaz Kylheku2021-08-131-3/+28
| | | | | | | | | | | | | * lisplib.c (match_set_entries): Intern the match-error symbol. Register autoloads for must-match and must-match-case. * stdlib/match.tl (match-error): Register exception symbol, as subtype of match-error. (must-match, must-match-case): New macros. * tests/011/patmatch.tl: Test cases. * txr.1: Documented.

* lazy-stream-cons: control close throwing behavior.Kaz Kylheku2021-08-071-4/+35
| | | | | | | | | | | | | | | | | | | | | | | | | * eval.c (eval_init): Update registrations of lazy-stream-cons and get-lines with one more optional argument. * lib.c (simple_lazy_stream_func_nt, lazy_stream_func_nt): New static functions. (lazy_stream_cons): Take a new argument, no_throw_close, defaulting it to nil. When calling close_stream directly, pass the inverted value of no_throw_close. Choose the new _nt functions for the lazy list if no_throw_close is true; those functions pass nil as the second argument of close_stream. * lib.h (lazy_stream_cons): Declaration updated. * match.c (v_next_impl, open_data_source, match_fun): Pass down the nothrow value to lazy_stream_cons, or else nil in situations when that is not applicable or there is no such value. Thus the :nothrow feature of v_next will now not only ensure that there is no exception when opening the stream but also when closing it. Unusual situations encountered when the lazy list reads from the stream still throw. * txr.1: Documented.
* doc: document nested do.Kaz Kylheku2021-08-061-0/+55
| | | | * txr.1: Document do being applied to do/op.
* txr: @(eof) takes argument for binding termination status.Kaz Kylheku2021-08-051-1/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We extend the matching context structures to keep track of the underlying stream from which lines are being taken via the lazy list. Then the implementation of the @(eof) directive, when it hits the eof condition, can use this stream to gain access to the termination status. * match.c (match_line_ctx, match_files_ctx): New member, stream. (ml_all): Take stream argument and initialize new member. (h_call, do_match_line): Pass stream argument to h_call. (mf_all, mf_file_data): Take stream argument and initialize new member. (mf_from_ml): Propagate stream from line context to file context. (freeform_prepare, v_next_impl, match_filter, match_fun, extract): Pass stream argument where now needed. (v_eof): Implement termination status binding via the stream stored in the context. (open_data_source): Store stream in match files context. * tests/010/eof-status.txr: New file. * tests/010/eof-status.expected: New file. * Makefile (tst/tests/010/eof-status.ok): -B option for new test. * txr.1: Documented eof directive, argument and all. * stdlib/doc-syms.tl: Updated.
* close-stream: make idemponent.Kaz Kylheku2021-08-041-5/+5
| | | | | | | | | | | | | | | | | | * stream.c (strm_base_init): Add new element to the initializer to initialize the close_result member to nao, indicating that the close operation has not been invoked. (strm_base_mark): Mark the close_result value, if it isn't nao. This is just in case it is a heap object. The structure delegate mechanism opens the possibility that the stream is actually user code that can return anything so we have to be careful. (close_stream): Only call ops->close if close_result is nao, indicating that close had never been called (or possibly that it had been called bu threw an exception) and store the return value in close_result, otherwise return the previously stored value. * stream.h (struct strm_base): New member, close_result. * txr.1: Documented.
* listener: print prompts in plain mode if stdin is tty.Kaz Kylheku2021-08-031-8/+5
| | | | | | | * linenoise/linenoise.c (linenoise): Force the printing of prompts if the input file descriptor is a tty. * txr.1: Documentation updated.
* listener: prompt feature for plain mode.Kaz Kylheku2021-08-031-2/+12
| | | | | | | | | | | | | | | | | | The :prompt-on command will enable prompting in plain mode. * linenoise/linenoise.c (struct lino_state): New member, show_prompt. (line_enable_noninteractive_prompt): New function. (linenoise): In the plain mode loop, the show_prompt flag is on, show the prompt. For continuation lines, show a condensed prompt, which consists of the suffix of the full prompt, starting on the last non-whitespace character. * linenoise/linenoise.h (lino_enable_noninteractive): Declared. * parser.c (repl): Implement :prompt-on command which enables the above mode. * txr.1: Documented.
* streams: document redundant close-stream.Kaz Kylheku2021-08-021-0/+10
| | | | | * txr.1: Document that if close-stream is applied to a closed stream, then nil is returned without throwing an exception.
* streams: bad argument defaulting in close-stream.Kaz Kylheku2021-08-021-3/+3
| | | | | | | | | | | | | | | * stream.c (stdio_close, pipe_close): Fix throw_on_error argument not being defaulted correctly, so that errors are thrown even when the argument is omitted. * strudel.c (strudel_close): Here, we also must default the argument. The corresponding close method does not have an optional argument; it is mandatory. The documentation is bungled for it, though. * txr.1: Fix documentation of structure delegate streams with regard to the close method. It does not take offs and whence parametrs, but throw-on-error-p, which is mandatory.
* listener: support multi-line expressions in plain mode.Kaz Kylheku2021-08-011-0/+8
| | | | | | | | | | | | | * linenoise/linenoise.c (linenoise): If we are in noninteractive mode, then do not just read one line and return it. If an enter_callback is defined then keep accumulating lines while the callback indicates incomplete syntax, until EOF occurs or the syntax appears complete. Return the lines glued together, with \n characters replaced by \r, so the line is correctly entered into the history, and the trailing LF obliterated, as usual. * txr.1: Documented new multi-line behavior of plain mode.
* oop: fix infelicity in new* and lnew* macros.Kaz Kylheku2021-07-311-1/+72
| | | | | | | | | | * stdlib/struct.tl (sys:new-expander): If the argument of new* or lnew* is dwim, then treat that as an expression, rather than as a boa-style construction. * tests/012/oop.tl: Tests for new* focusing on this issue. * txr.1: Documented.
* doc: *read-bad-json* fix and doc-syms update.Kaz Kylheku2021-07-311-1/+1
| | | | | | * txr.1: Fix code -> codn. * stdlib/doc-syms.tl: Updated.
* parser: allow trailing commas in json, via opt-in flag.Kaz Kylheku2021-07-291-0/+24
| | | | | | | | | | | | | | | | | | | | | | | * parser.c (read_bad_json_s): New symbol variable. (parser_common_init): Propagate value of *read-bad-json* into read_bad_json flag in parser structure. (parser_init): Initialize read_bad_json_s and register the *read-bad-json* dynamic variable. * parser.h (struct parser): New member, read_bad_json. (read_bad_json_s): Declared. * parser.y (json_val): Support an opt_comma symbol just before the closing bracket or brace. (opt_comma): New nonterminal symbol. Recognizes ',' or nothing. Error is flagged if ',' is recognized, and *read-bad-json* is nil. * y.tab.c.shipped: Updated. * tests/010/json.tl: New tests. * txr.1: Documented.
* subtypep: handle struct type objects.Kaz Kylheku2021-07-271-6/+14
| | | | | | | | | | | | | The subtypep function has poor requirements, handling only type symbols. Let's extend it to handle structure type objects. * lib.c (subtypep): In all cases when an argument is considered to be a possible structure symbol, and thus subject to find_struct_type, consider whether it already is a struct type, and just take it as-is. * tests/012/type.tl: New tests. * txr.1: Updated.

* hash: support both semantics of weak keys + values.Kaz Kylheku2021-07-211-13/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hash tables with weak keys and values now support a choice of both possible semantics: under and-semantics, an entry lapses when both the key and value are unreachable. Under or-semantics, an entry lapses if either the key or value is unreachable. The and-semantics is new. Until TXR 266, only or-semantics was supported. This will be the default: when a hash table is specified as :weak-keys and :weak-vals, it will have or-semantics. The keywords :weak-or and :weak-and specify weak keys and values, with the specific semantics. They are utually exclusive, but tolerate the presence of :weak-keys and :weak-vals. The make-hash function is being extended such that if its leftmost argument, <weak-keys>, is specified as one of the keywords :weak-and or :weak-or, then the hash table will have weak keys and values with the specified semantics, and the <weak-vals> argument is ignored (values are weak even if that argument is false). * eval.c (eval_init): Initially register the top_vb, top_mb, top_smb, special and builtin hashes as ordinary hashes: no weak keys or values. Then use tweak_hash to switch to weak keys+vals with and-semantics. We do it this way because the keywords are not yet initialized; we cannot use them. * hash.h (enum hash_flags, hash_flags_t): Moved to header. Member hash_weak_both renamed to hash_weak_or. New member hash_weak_and. (weak_and_k, weak_or_k): New keyword variables. (hash_print_op): Handle hash_weak_and by printing :weak-and. (hash_mark): Handle hash_weak_and by marking nothing, like hash_weak_or. (do_make_hash): Check first argument against the two new keywords and set flags accordingly. This function is called from eval_init before the keywords have been initialized, in which case weak_keys == weak_and_k is true when both are nil; we watch for that. (tweak_hash): Now returns void and takes a hash_flags_t argument which is simply planted. (do_wak_tables): Implement hash_weak_and case. Remove the compat 266 stuff from hash_weak_or. Compatibility is no longer required since we are not changing the default semantics of hash tables. Phew; that's a load of worry off the plate. (hashv): Parse the two new keywords, validate and provide semantics. (hash_init): Initialize weak_and_k and weak_or_k kewyords. * hash.h (enum hash_flags, hash_flags_t): Moved here now. (weak_and_k, weak_or_k): Declared. * lib.c (compat_fixup): Remove call to parse_compat_fixup. * parser.c (parse_init): Create stream_parser_hash with and-semantics. (parse_compat_fixup): Function removed. * parser.h (parse_compat_fixup): Declaration removed. * txr.1: Hash documentation updated.
* hash: change semantics of weak-both hash tables.Kaz Kylheku2021-07-201-3/+17
| | | | | | | | | | | | | | | | From now on, hash tables with both weak keys and values have dijunctive retention semantics. If either the key or value of an entry is reachable, then the entry stays. This is subject to compatibility. * hash.c (do_weak_tables): Expire an entry if neither the key nor the value is reachable. In 266 or lower compatibility mode, expire an entry if either the key or value is unreachable, like before. * txr.1: Document the change, with compat notes. Add a cautionary note about the referencing issue which defeats weak key or weak value tables.
* hash: revert bad fix in weak processing.Kaz Kylheku2021-07-201-7/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit reverts the April 11, 2020 commit a4c376979d15323ad729e92e41ba43768e8dc163, subject line "hash: bugfix: spurious retention in weak processing". That commit is a regression. This revert requires a follow-up; the commit was trying to fix an issue which now reappears. It will have to be fixed differently. The regression is that in a situation in which data is referenced through two or more dependent weak tables, entries that are reachable can spontaneously disappear from downstream tables. Suppose H0 and H1 are weak-key tables. Suppose the program holds a datum K0, which is the only reference through which D1 is reached, in the following chain: K0 -> [H0] -> K1 -> [H1] -> D1 K0 is a key in hash table H0, which has weak keys. The the associated value K1 is a key in H1, which then references D1. H0 holds the only reference to K1, and H1 holds the only reference to D1. During the first GC marking phase, because we do not mark any part of a table which has weak keys, when we process H0 we do not mark the value K1. Thus K1 looks unreachable. In the second weak hash processing pass, because K1 was treated as unreachable, the <K1, D1> entry in H1 is incorrectly expired. This issue affects TXR's origin_hash and form_to_ln_hash, which are in this relationship. The problem was uncovered in recent tags.tl work, manifesting as a spurious disappearance of line number info when processing .txr files. The line number info disappeared for entries which were traced through the origin_hash via the macro-ancestor function (see the unexpand function in tags.tl). * hash.c (hash_mark): Only skip marking tables that have both weak keys and values. For weak key tables, mark all the values and vice versa: for weak value tables, mark the keys. * txr.1: Text resembling original text restored.
* doc: warm-up-period argument of make-random-state.Kaz Kylheku2021-07-131-7/+14
| | | | | | * txr.1: Add missing requirement: warm-up is also not performed if make-random-state is a vector. Improve the wording overall.
* rand: support buffers as random seeds.Kaz Kylheku2021-07-131-5/+5
| | | | | | | | | * rand.c (make_random_state): Recognize buffer object as sources of bits for seeding. * tests/013/rand.tl: New file. * txr.1: Documented.
* New functions: getrlimit, setrlimit.Kaz Kylheku2021-07-131-0/+92

* New: build-id feature.Kaz Kylheku2021-07-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | A build-id is a string optionally embedded into TXR at build time which can be displayed with a command line option. It can help developers who are juggling multiple builds in their workspace to identify what they are running. * Makefile (txr.o, txr-win.o): If a build_id has been defined, then define the TXR_BUILD_ID macro on the command line when compiling these object files. * configure (build_id): New variable. (help) Describe build_id. (gen_config_make): Generate build_id and build_id_exp make variables. * txr.1: Documented --build-id option. * tsr.c (build_id): Conditionally defined global variable. (help): Brief help string for --build-id. (txr_main): Process --build-id option.
