* exceptions: hack to store errno in string object.Kaz Kylheku2021-09-071-0/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basic idea: when we throw an exception that pertains to a system error which has an errno code, we can stick the errno into the memory area of the character string, into the wchar_t that immediately follows the null terminator. We can do this because strings track their actual allocation size. A pair of setter/getter functions to set and retrieve this value are provided, and all functions in the code which can set such a code are updated to do so, simply by calling the newly added uw_ethrowf that drop-in replaces for uw_throwf. * lib.[ch] (string_set_code, string_get_code): New functions. * unwind.[ch] (uw_ethrowf): New function. * eval.c (eval_init): Register string-set-code and string-get-code intrinsics. * ftw.c (ftw_wrap): Switch to uw_ethrowf. * parser.c (open_txr_file): Likewise. * socket.c (dgram_overflow): Store the ENOBUFS error in errno, and use uw_ethrowf instead uw_throwf. (dgram_get_byte_callback, dgram_flush, sock_bind, to_connect, open_sockfd, sock_connect, sock_listen, sock_accept, sock_shutdown, sock_timeout, socketpair_wrap): Switch to uw_ethrowf. * stream.c (dev_null_get_fd, stdio_maybe_read_error, stdio_maybe_error, stdio_close, pipe_close, open_directory, open_file, open_fileno, open_tail, fds_subst, open_subprocess, open_command, remove_path, rename_path, tmpfile_wrap, mkdtemp_wrap, mkstemp_wrap): Switch to uw_ethrowf. * sysif.c (mkdir_wrap, ensure_dir, chdir_wrap, getcwd_wrap, rmdir_wrap, mknod_wrap, mkfifo_wrap, chmod_wrap, do_chown, symlink_wrap, link_wrap, readlink_wrap, close_wrap, val exec_wrap, stat_impl, do_utimes, pipe_wrap, poll_wrap, getgroups_wrap, setuid_wrap, seteuid_wrap, setgid_wrap, setegid_wrap, setgroups_wrap, getresuid_wrap, setresuid_wrap, setresgid_wrap, crypt_wrap, uname_wrap, opendir_wrap, getrlimit_wrap, setrlimit_wrap): Likewise. * termios.c (tcgetattr_wrap, tcsetattr_wrap, tcsendbreak_wrap, tcdrain_wrap, tcflush_wrap, tcflow_wrap): Likewise. * tests/018/errno.tl: New file. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* string-finish: new function.Kaz Kylheku2021-09-071-0/+20
| | | | | | | | | | | | * eval.c (eval_init): Register string-finish intrinsic. * lib.c (string_finish): New function. * lib.h (string_finish): Declared. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* string-extend: third optional argument.Kaz Kylheku2021-09-071-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A Boolean optional argument to string-extend indicates whether this is likely the last call to string-extend, so memory can be trimmed accordingly. * eval.c (eval_init): Update string-extend registration. * filter.c (trie_filter_string): Pass nil for new argument of string_extend. * lib.c (str_seq, replace_str, lazy_str_force, lazy_str_force_upto): Pass nil for new argument of string_extend. (rem_impl, remove_if, separate): Pass t for new argument of string_extend on last iteration, nil otherwise. (string_extend): Implement new third argument, defaulted to nil. Switch from chk_grow_vec to the more specific chk_wrealloc, which simplifies the code. * lib.h (string_extend): Declaration updated. * parser.y (litchars): Pass t as last argument of string_extend since we know syntactically that these reductions finalize the string. (restlitchar): Pass nil as the last argument of string_extend, since we know syntactically that it isn't the last. * regex.c (scan_until_common): Pass nil for new argument of string_extend. * txr.1: Documented.
* ffi: ffi macro uses load-time.Kaz Kylheku2021-09-061-1/+1
| | | | | | | | | | | | | | | A number of functions take an argument which is a ffi type. Typically, this argument is produced using by a ffi-type-compile call which is produced by the ffi macro. But this ffi-type-compile call is invoked at run time, each time such a function is called. A solution for this is to have the ffi macro hoist the compilation to load time. * stdlib/ffi.tl (ffi): Add load-time wrapping to generated expression. * txr.1: Updated correspondence between (ffi ...) form and equivalent (ffi-type-compile form).
* doc: fix description of carray-uint type argument.Paul A. Patience2021-09-061-1/+1
| | | | | | | | The optional type argument of carray-uint and carray-int was documented as defaulting to uint, but it actually defaults to uchar. * txr.1: uint -> uchar.
* ffi: add socklen-t type.Paul A. Patience2021-09-061-1/+1
| | | | | | | | | | * ffi.c: Include <sys/socket.h> if we HAVE_SOCKETS. (ffi_init_extra_types): Initialize socklen-t type if we HAVE_SOCKETS. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* doc: remove beta status from quasiliteral match.Kaz Kylheku2021-09-041-5/+0
| | | | | | * txr.1: Looks like quasiliteral patterns are staying the way they are. The feature has been out for a number of releases, so can be considered out of beta.
* doc: mention newer macros in pattern matchingKaz Kylheku2021-09-041-0/+14
| | | | | * txr.1: Structural Pattern Matching info now mentions and describes the two never macros.
* load: scope change for load hooks.Kaz Kylheku2021-09-031-19/+12
| | | | | | | | | | | | | | * eval.c (run_load_hooks): Install the given environment as dyn_env temporarily, and don't restore it until after calling the hooks. Thus the specified environment is now in effect when running the hooks. Also, pass nil to lookup_var, in the spirit of the previous commit. The fact that load_dyn_env had to be passed to lookup_var previously, which is an anti-pattern, tells us that this scoping rule was a code smell. If the *load-hooks* value comes from a given dynamic environment, then those functions should be executed in exactly that environment. * txr.1: Documentation updated.
* load: new macros push-after-load and pop-after-load.Kaz Kylheku2021-09-031-0/+38
| | | | | | | | | | | | | * eval.c (me_push_after_load, me_pop_after_load): New static functions. (eval_init): Register push-after-load and pop-after-load intrinsic macros. * tests/019/load-hook.tl: Tests for correct expansion. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* 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. (MAP_GROWSDOWN, MAP_LOCKED, MAP_NORESERVE, MAP_POPULATE, MAP_NONBLOCK, MAP_STACK, MAP_HUGETLB, MAP_SHARED, MAP_PRIVATE, MAP_FIXED, MAP_ANON, MAP_HUGE_SHIFT, MAP_HUGE_MASK, PROT_READ, PROT_WRITE, PROT_EXEC, PROT_NONE, PROT_GROWSDOWN, PROT_GROWSUP, MADV_NORMAL, MADV_RANDOM, MADV_SEQUENTIAL, MADV_WILLNEED, MADV_DONTNEED, MADV_FREE, MADV_REMOVE, MADV_DONTFORK, MADV_DOFORK, MADV_MERGEABLE, MADV_UNMERGEABLE, MADV_HUGEPAGE, MADV_NOHUGEPAGE, MADV_DONTDUMP, MADV_DODUMP, MADV_WIPEONFORK, MADV_KEEPONFORK, MADV_HWPOISON, MS_ASYNC, MS_SYNC, MS_INVALIDATE): #define as 0 if missing.

* doc: misspelled cond in ecase section.Kaz Kylheku2021-08-221-1/+1
| | | | * 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: @(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

* 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.
