* New Lisp feature: param list expander.Kaz Kylheku2017-01-041-0/+17
| | | | | | | | | | | | | | | | | | | | | * eval.c (pm_table): New static variable. (expand_param_macro): New static function. (expand_params): Expand parameter list macros via expand_param_macro. (eval_init): gc-protect pm_table and initialize it. Register *param-macro* variable. * lisplib.v (pmac_set_entries, pmac_instantiate): New static functions. (lisplib_init): Register autoloading of pmac.tl via new functions. * share/txr/stdlib/pmac.tl: New file. * txr.1: Notes under defun, lambds, flet/labels and defmacro about the existence of parameter macros which add to the syntax. New Parameter List Macros section. Documented *param-macro* and define-param-expander.
* Bugfix: repeated expansion of catch unstable.Kaz Kylheku2016-12-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out we have a silly problem: catch is a special operator, which undergoes a macro-like expansion which alters its syntax, but uses the same operator symbol. We turn catch into a macro which expands to a sys:catch operator. * eval.c (sys_catch_s): New symbol variable. (expand_catch): Function now expands sys:catch forms without altering any syntax. (do_expand): Check for sys:catch rather than catch. Call expand_catch differently: it takes the form now instead of just the arguments, so it can return the original form if no expansion takes place. (eval_init): Initialize sys_catch_s variable. Change registration of op_catch to sys:catch symbol. * lisplib.c (except_set_entries): Add catch to the list of autoload symbols for except.tl. * share/txr/stdlib/except.tl (catch): New macro for transforming catch to sys:catch. * txr.1: Reclassify catch operator as a macro.
* Adding prog and prog* macros.Kaz Kylheku2016-12-131-1/+1
| | | | | | | | | * lisplib.c (tagbody_set_entries): Add prog and prog* to autoload list. * share/txr/stdlib/tagbody.tl (prog, prog*): New macros. * txr.1: Documented.
* Expander warns about unbound variables.Kaz Kylheku2016-11-261-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * eval.c (eval_exception): New static function. (eval_error): Reduced to wrapper around eval_exception. (eval_warn): New function. (me_op): Bind the rest symbol in a shadowing env to suppress watnings about unbound rest. (do_expand): Throw a warning when a bindable symbol is traversed that has no binding. (expand): Don't install atoms as last_form_expanded. * lib.c (warning_s, restart_s, continue_s): New symbol variables. (obj_init): Initialize new symbol variables. * lib.h (warning_s, restart_s, continue_s): Declared. * lisplib.c (except_set_entries): New entries for ignwarn and macro-time-ignwarn. * parser.c (repl_warning): New static function. (repl): Use repl_warning function as a handler for warning exceptions: to print their message and then continue by throwing a continue exception. * parser.y (warning_continue): New static function. (parse_once): Use warning_continue to ignore warnings. In other words, we suppress warnings from Lisp that is mixed into TXR pattern language code, because this produces too many false positives. * share/txr/stdlib/except.tl (ignwarn, macro-time-ignwarn): New macros. * share/txr/stdlib/place.tl (call-update-expander, call-clobber-expander, call-delete-expander): Ignore warnings around calls to sys:expand, because of some gensym-related false positives (we expand code into which we inserted some gensyms, without having inserted the constructs which bind them. * tests/011/macros-2.txr: Suppress unbound variable warnings from a test case. * tests/012/ifa.tl: Bind unbound x y variables in one test case. * tests/012/struct.tl: Suppress unbound variable warnings in some test cases. * uwind.c (uw_throw): If a warning is unhandled, then print its message with a "warning" prefix and then throw a continue exception. (uw_register_subtype): Eliminate the check for sub already being a subtype of sup. This allows us to officially register new types against t. (uw_late_init): Register continue exception type as a subtype of the restart type. Formally register warning type. * txr.1: Documented ignwarn.
* Adding a tagbody macro to the language.Kaz Kylheku2016-11-181-0/+17
| | | | | | | | | | | | | | | | | | | | | | | This is a "disciplined goto" feature of Common Lisp. This uses a new sys:switch operator, which could also be used for optimizing case and cond forms. * eval.c (switch_s): New symbol variable. (op_switch, expand_list_of_form_lists, expand_switch): New static functions. (do_expand): Hook in the expansion of the sys:switch operator. (eval_init): Initialize switch_s special variable to sys:switch symbol. Register sys:switch special op. * lisplib.c (tagbody_set_entries, tagbody_instantiate): New static functions. (lisplib_init): Register autoloading of tagbody module via new functions. * share/txr/stdlib/tagbody.tl: New file. * txr.1: Documented.

| | | | | | | | | | | | | | | | * lisplib.c (getput_set_entries, getput_instantiate): New static functions. (dlt_register): Register auto-loading for getput module via new functions. * share/txr/stdlib/getput.tl: New file. * txr.1: Documented new functions file-get, file-put, file-append, file-get-string, file-put-string, file-append-string, file-get-lines, file-put-lines, file-append-lines, command-get, command-put, command-get-string, command-put-string, command-get-lines, and command-put-lines.
* Add defpackage macro.Kaz Kylheku2016-11-111-0/+19
| | | | | | | | | | | * lisplib.c (package_set_entries, package_instantiate): New static functions. (lisplib_init): Register auto-loading for new package.tl file using new functions. * share/txr/stdlib/package.tl: New file. * txr.1: Documented.
* Implement *package* special var; package overhaul.Kaz Kylheku2016-11-081-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * eval.c (load): Rebind *package* in the local dynamic environment already established for the sake of *load-path*. By doing this we cause *package* to be restored to its prior value, which allows the loaded file to alter it. Common Lisp works this way. (eval_init): Register *package* variable, with the user package as its default value. * lib.c (package_s): New symbol variable. (intern, rehome_sym): Default the package argument to the current package, not to user_package. (get_user_package, get_system_package, get_keyword_package): Functions removed. (get_current_package): New function. (obj_print_impl): Revise symbol printing. Keyword and uninterned symbols are printed with : and #: prefixes. The remainder are printed with a package prefix if their home package isn't the current package. * lib.h (keyword_package, user_package, system_package): These macros are just straight aliases for the global variables, not going through the lookup mechanism, which was pointless. (cur_package): New macro. (package_s): Declared. (get_current_package): Declared. * lisplib.c (lisplib_try_load): Establish a local dynamic environment, and bind the *package* variable to the user package which the library modules expect. * parser.c (find_matching_syms, provide_completions): Treat unqualified symbols in the current package rather than user package. * parser.y (sym_helper): Intern unqualified symbols in the current package, not user package. * txr.1: Document that the variables user-package, system-package and keyword-package should not be modified. Document the *package* special variable, and that intern and rehome-sym default their package argument to its value. (Here we get rid of wrong references to the undocumented variable *user-package*).
* Introducing command line option processing system.Kaz Kylheku2016-11-031-0/+19
| | | | | | | | | | | * lisplib.c (getopts_set_entries, getopts_instantiate): New functions. (lisplib_init): Register auto-loading for getopt.tl via new functions. * share/txr/stdlib/getopts.tl: New file. * txr.1: Documented new library area.

* Adding family slot to socket addresses.Kaz Kylheku2016-10-131-1/+1
| | | | | | | | | | | | | | | A static slot indicating the address family simplifies code which wants to map a socket address to its family. * lisplib.c (sock_instantiate): Call sock_load_init before loading socket.tl rather than after, because socket.tl now references variables defined inside sock_load_init. * share/txr/stdlib/socket.tl (sockaddr, sockaddr-in, sockaddr-in6, sockaddr-un): New static slot, family. * txr.1: Documented family slots.
* Synchronize license comments with LICENSE.Kaz Kylheku2016-10-011-16/+17

(rlet): Replace body with call to sys:r-s-let-expander. (slet): New macro. * txr.1: Clarification and corrections in rlet description and example. rlet will in fact handle the three-variable rotation case because, since a is not a constant expression, (rlet ((temp a)) ...) reduces to let. Documented new slet.

(rslot, rslot): New macro and place macro. (sys:rslot): New place kind.
* The stdlib variable gets a trailing slash.Kaz Kylheku2016-06-051-14/+14
| | | | | | | | | | | | | | | | | | | * txr.c (sysroot_init): Add slash to stdlib_path. (sysroot_compat_fixup): Replace user-visible stdlib variable with a path that doesn't have a slash, if compatibility is 143 or lower. (compat): Call sysroot_compat_fixup. * lisplib.c (place_set_entries, ver_set_entries, ifa_set_entries, txr_case_set_entries, with_resources_set_entries, path_test_set_entries, struct_set_entries, with_stream_set_entries, hash_set_entries, except_set_entries, type_set_entries, yield_set_entries, sock_set_entries, termios_set_entries): Remove slash from format string since the directory includes it. * txr.1: Added note under stdlib about the slash, and also an entry COMPATIBILITY.
