* ifa: take advantage of read-once.Kaz Kylheku2021-10-261-1/+7
| | | | | | | | | | * stdlib/ifa.tl (ifa): When the form bound to the it anaphoric variable is a place, such that we use placelet, wrap the place in (read-once ...) so that multiple evaluations of it don't cause multiple accesses of the place. * txr.1: Documented.
* places: new accessor read-once.Kaz Kylheku2021-10-261-0/+170
| | | | | | | | | | | * lisplib.c (place_set_entries): Trigger autoload on read-once. * stdlib/place.t (read-once): New function and place. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* random: new function random-float-incl.Kaz Kylheku2021-10-251-1/+31
| | | | | | | | | | | | This function includes the 1.0 value excluded by random-float. * rand.c (random_float_incl): New static function. (rand_init): Register random_float_incl intrinsic. * txr.1: Document, and add discussion about uniformity requirements and what they mean and do not mean. * stdlib/doc-syms.tl: Updated.
* ffi: implement in-semantics for carray, cptr.Kaz Kylheku2021-10-241-5/+48
| | | | | | | | | | | | | * ffi.c (ff_cptr_in, ffi_carray_in): New static functions. (ffi_type_compile): Wire in new functions for dynamically compiled cptr and carray types. (ffi_init_types): Also, wire in ffi_cptr_in function for the non-parametrized cptr type. (carray_set_ptr): New function. * ffi.h (carray_set_ptr): Declared. * txr.1: Documented.
* doc: document (...) pic patternsKaz Kylheku2021-10-201-21/+58
| | | | | | * txr.1: Document the parenthesized pattern notation for obtaining a negative number with parentheses. Also putting the escape syntax first, because it's a short section.
* pic: preserve decimal period in ### overflow fill.Kaz Kylheku2021-10-181-3/+21
| | | | | | | | | | | | | | | | | | * pic.tl (expand-pic-num): If the overflowing field specifies a decimal point other than in the rightmost position, then stick one into the fill pattern. The motivation for this is that it harmonizes with the digit separators. The new digit separator insertion logic will treat the # characters like digits, and requires the embedded decimal in order to work properly. Allowing digit separation to work in the fill pattern will make for better looking output in column displays. That's the same reason why we insert digit separators among leading zeros. * tests/018/format.tl: Overflow test cases updated in light of this requirement change. * txr.1: Documented.
* pic: new feature: digit-separating commas.Kaz Kylheku2021-10-181-3/+32
| | | | | | | | | | | | | | | | This allows for pic patterns like #,###,###.### which incorporate digit separating commas into the output. * stdlib/pic.tl (comma-positions, insert-commas, expand-pic-num-commas): New system functions. (expand-pic): Recogize comma as a character which can be escaped using the tilde. Recognize a more complicated numeric pattern with commas. If the matched token contains commas, treat it using expand-pic-num-commas. (pic): Propagate a copy of the new numeric pattern here, where it is used for separation into tokens. * txr.1: Documented.
* printer: bug: fallback syms printed without prefix.Kaz Kylheku2021-10-121-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | This is a basic read/print consistency problem. When a symbol is printed that is anywhere in the fallback list of the current package, we are dumping it unqualified, even if it is hidden by a same-named symbol in the current package itself or such a symbol occurring earlier in the fallback list. * lib.c (symbol_needs_prefix): When the to-be-printed symbol is found in the fallback list, re-scan the current package for a symbol having the same name, as well as the preceding nodes in the fallback list. If such a symbol is found, then the to-be printed symbol must be package-qualified. * tests/012/syms.expected: New file. * tests/012/syms.tl: Likewise. * tests/012/compile.tl: Pull syms into compile job. * txr.1: Clarify text about this. The existing text's only reasonable interpretation supports the behavior which this patch ensures (which is needed on grounds of read/print consistency) but the text lacks precision.
* New path-equal function.Kaz Kylheku2021-10-101-0/+68
| | | | | | | | | | * lisplib.c (copy_file_set_entries): Add path-equal to autoload symbols. * stdlib/copy-file.tl (path-equal): New function. * tests/018/path-equal.tl: New file. * txr.1: Documented.
* Version 271.txr-271Kaz Kylheku2021-10-051-3/+3
| | | | | | | | | | | | | | * RELNOTES: Updated. * configure (txr_ver): Bumped version. * stdlib/ver.tl (lib-version): Bumped. * txr.1: Bumped version and date. * txr.vim, tl.vim: Regenerated. * protsym.c: Likewise.
* awk: :fields specifies conversions.Kaz Kylheku2021-10-041-30/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * stdlib/awk.tl (sys:awk-compile-time): Slot field-names renamed to field-name-conv. (sys:awk-expander): Parse the new syntax which allows (sym fn) pairs with optional fn, creating a list of normalized items in the field-name-conv slot of the compile-time structure. (sys:awk-symac-let): Adjust the code to the pair representation in field-name-conv. (sys:awk-field-name-code): New function for generating the field conversion code. (awk): Now that we have two optional pieces of code to wrap around p-actions form, we factor that out of the awk-lambda, to a series of conditional assignments. Here we handle the generation of the field conversionns. * conv.tl (sys:conv-expand-sym): New macro, used in sys:awk-field-name-code and sys:conv-let. (sys:conv-let): Simplify with sys:conv-expand-sym. Drop optional argument from i; it connects with no documented feature, and is not usable from fconv. * tests/015/awk-fields.tl: New tests. * txr.1: Updated, including cruft in fconv documentation.

* doc: fix trivial typos and stylistic issues.Paul A. Patience2021-10-041-73/+71
| | | | * txr.1: Fix typos and stylistic issues.
* doc: fix refs to inexistent fill- and put-array.Paul A. Patience2021-10-041-8/+8
| | | | | | | * txr.1: fill-array -> fill-carray, put-array -> put-carray. Refer to fill-buf and put-buf with .code (or .codn). Use .code when referring to a carray object rather than an argument called carray.
* ffi: add cptr-carray function.Paul A. Patience2021-10-021-0/+36
| | | | | | | | | | | * ffi.c (cptr_carray): New function. (ffi_init): Register cptr-carray intrinsic. * ffi.h (cptr_carray): Declared. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* awk: new :fields feature for named fields.Kaz Kylheku2021-10-011-0/+34
| | | | | | | | | | | | | * stdlib/awk.tl (sys:awk-compile-time): New slot, field-names. (sys:awk-expander): Validate and store field-names into compile-time structure. (sys:awk-symac-let): New macro. (awk): Wrap sys:awk-symac-let around code to generate field name macros. * tests/015/awk-fields.tl: New file. * txr.1: Documented.
* New variable: *child-env*.Kaz Kylheku2021-09-261-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | This specifies the environment to be used for executing programs. * stream.c (open_subprocess, run): Check *child-env* variable and if other than t, then install the environment before execvp. In the spawn-based version of run, we save and restore the environment around the spawn call, if *child-env* is in effect. * sysif.c (child_env_s): New symbol variable. (exec_wrap): If *child-env* is other than t, then save the environment in a list, and install the specified environment before calling execvp. If that function returns, restore the environbment. * sysif.h (child_env_s): Declared. (child_env): New macro. * tests/018/process.tl: New tests. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* New function: replace-env.Kaz Kylheku2021-09-251-0/+45
| | | | | | | | | | | | | | | | | | | Using this new function together with env, it's now possible to save the set of environment variables, clobber it to a specified set (possibly empty) and then restore it. Useful for improved security in running child processes. * lib.[ch] (chk_substrdup_utf8): New function. * sysif.c (replace_env): New function. (sysif_init): Register replace-env intrinsic. * sysif.h (replace_env): Declared. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* path access tests: use real credentials.Kaz Kylheku2021-09-251-15/+20
| | | | | | | | | | | | | | | | | The various accessibility functions like path-writable-to-me should use the real credentials, the same way that the POSIX access function does. This makes them much more useful and secure in setuid programs, since they answer the question "does the underlying user, without these elevated privileges, have this access". * stdlib/path-test.tl (path-mine-p): Use getuid, not geteuid. (path-my-group-p): Use getgid, not getegid. (sys:path-access, path-private-to-me, path-strictly-private-to-me): Use getuid, getgid and rename euid variable to uid. * txr.1: Updated.
* path-search: rewrite in C with saner semantics.Kaz Kylheku2021-09-251-52/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | The new function: - just returns the name if it contains path name components. - returns nil if the name is "." or "..". - tests for existence only, not permission to execute. * lisplib.c (path_test_set_entries): Do not auto-load path-test module on the path-search symbol, since it is no longer implemented there. * stdlib/path-test.tl (path-search): Function removed. * stream.c (path_var_sep_char): New global variable. (path_search): New function. (detect_path_separators): Also set path_var_sep_char to semicolon on Cygnal. (stream-init): Register path-search intrinsic here now. * stream.h (path_var_sep_char, path_search): Declared. * tests/018/path-test.tl: New tests. * txr.1: Documentation revised for path-search.
* New variants of each operator for sum and product.Kaz Kylheku2021-09-231-0/+120
| | | | | | | | | | | | | | | | | | | | | | | | | * lisplib.c (arith_each_instantiate, arith_each_set_entries): New functions. (each_prod_set_entries): Add sum-each-prod, sum-each-prod*, mul-each-prod and mul-each-prod* as autoload triggers for each-prod.tl, where those macros are now defined. (lisplib_init): Register autoloading of arith-each.tl via the two new functions. * stdlib/arith-each.tl: New file. * stdlib/each-prod.tl (sys:expand-each-prod*): Handle sum-each-prod* and mul-each-prod* in the same way, by mapping to their parallel binding counterparts. (sys:expand-arith-each-prod): New function. (sym-each-prod, mul-each-prod, sum-each-prod*, mul-each-prod*): New macros. * tests/016/arith.tl: New tests. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.

* doc: sock-opt: found proper way to escape ...Kaz Kylheku2021-09-221-2/+2
| | | | | | | * txr.1: To begin a troff line with a period that is to be treated as literal, we use \& before that dot, not simply \. This was giving warnings and not rendering properly. The \& produces good output in man, HTML and PDF.
* doc: fix problem in errno retrieval example.Kaz Kylheku2021-09-221-2/+0

| | | | | | * txr.1: Fix typos in .meIP and .mets lines. Fix a .code that should be .codn. Add missing closing parenthesis in description of greater function. Unparenthesize make-random-state in a .code.
* defset: add set-mask and clear-mask.Paul A. Patience2021-09-141-0/+40
| | | | | | | | | | | | | | | | | | | | * stdlib/defset.tl (set-mask, clear-mask): New update macros. * stdlib/optimize.tl (calc-liveness): Use the new macros. * stdlib/socket.tl (sys:str-inaddr-net-impl, str-in6addr-net): Same. * stdlib/termios.tl (set-iflags, set-oflags, set-cflags, set-lflags, clear-iflags, clear-oflags, clear-cflags, clear-lflags): Same. * lisplib.c (defset_set_entries): Add set-mask and clear-mask to autoload symbols for defset. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* ffi, sockets: add sock-opt and sock-set-opt.Paul A. Patience2021-09-121-5/+184
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new sock-opt and sock-set-opt functions are wrappers around getsockopt and setsockopt, respectively. All POSIX socket options are registered. Platform-specific options may be added in the future. * ffi.c (sock_opt, sock_set_opt): New functions. (ffi_init): Register sock-opt, sock-set-opt, sol-socket, ipproto-ip, ipproto-ipv6, ipproto-tcp, ipproto-udp, so-acceptconn, so-broadcast, so-debug, so-dontroute, so-error, so-keepalive, so-linger, so-oobinline, so-rcvbuf, so-rcvlowat, so-rcvtimeo, so-reuseaddr, so-sndbuf, so-sndlowat, so-sndtimeo, so-type, ipv6-join-group, ipv6-leave-group, ipv6-multicast-hops, ipv6-multicast-if, ipv6-multicast-loop, ipv6-unicast-hops, ipv6-v6only, tcp-nodelay. * lisplib.c (sock_set_entries): Add sock-opt and sock-set-opt. * stdlib/socket.tl (sock-opt): Define as syntactic place. * tests/014/socket-misc.tl: New cases, for sock-opt. (set-and-get): New macro. * txr.1: Documented. Also, mention that sock-bind enables so-reuseaddr. * stdlib/doc-syms.tl: Updated.
* doc: fix various important typos.Paul A. Patience2021-09-111-10/+10
| | | | | | | | | * txr.1: use-symbol -> use-sym; socket-open -> open-socket; af-inet -> af-unix in description of open-socket; r+ -> r+b in description of sock-accept; get-obj -> fill-obj in description of fill-obj; offs -> offset in description of carray-buf; caddr-ref -> carray-ref; caddr-refset -> carray-refset; fix int-carray's argument list.
* 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.
