* * lisplib.c (place_set_entries): Add *place-macro* andKaz Kylheku2015-07-221-2/+2
| | | | | | | | | | | | | | define-place-macro to list of names. * share/txr/stdlib/place.tl (*place-macro*): New global hash. (sys:tigger-load, sys:pl-expand): New functions. (call-update-expander, call-clobber-expander, call-delete-expander): Recognize and expand place macros. (define-place-macro): New macro. (first, rest): Places redefined using define-place-macro, replacing the old hack of copying the expanders from one table entry to another. * txr.1: Documented place macros.
* Implementing caar, cadr, cdar and friends.Kaz Kylheku2015-07-211-5/+5
| | | | | | | | | | | | | | | | | | | | * lib.c (init): Call cadr_init. * lisplib.c (dl_table, set_dlt_entries, dlt_register): Externalize. * lisplib.h (dl_table, set_dlt_entries, dlt_register): Declared. * Makefile (OBJS): Add cadr.o. * cadr.c: New file. * cadr.h: New file. * gencadr.txr: New file. * share/txr/stdlib/cadr.tl: New file. * txr.1: Document cadr accessors.
* * share/txr/stdlib/place.tl (place-form-p): New function.Kaz Kylheku2015-07-121-0/+1
| | | | * lisplib.c (place_set_entries): Add place-form-p to list of names.
* Let's have placelet and placelet*.Kaz Kylheku2015-07-111-1/+1
| | | | | | | | * share/txr/stdlib/place.tl (placelet*): New macro. * lisplib.c (place_set_entries): Add placelet* to list of names. * txr.1: Updated to document placelet* and fix mistakes.
* New placelet macro.Kaz Kylheku2015-07-101-0/+1
| | | | | | | | | | | | | | * lisplib.c (place_set_entries): Add placelet to list of names. * share/txr/stdlib/place.tl (sys:placelet1, placelet): New macros. (defplace dwim): Do not retrieve the place's value into a local variable and have the getter expand to that variable. Rather, have the getter retrieve the value. A getter that refers to a cached copy breaks the semantics of placelet, and any place operator which can evaluate the location after it is stored. * txr.1: Documented placelet.
* Bugfix: define-modify-macro not registered for auto-loading.Kaz Kylheku2015-08-081-1/+1
| | | | | * lisplib.c (place_set_entries): Add define-modify-macro to list of names.

| | | | | | | | | | | | | | * Makefile (GEN_HDRS, LISP_TO_C_STRING): Variables removed. (%.h: %.tl): Rule removed. The place.h header is no longer generated from place.tl. * lisplib.c (place_instantiate): Load place.tl from stdlib directory, rather than obtaining it from a string literal in generated header place.h. * place.tl: Moved to share/txr/stdlib directory. * genvim.txr: Refer to place.tl in stdlib.
* Library .txr files become .tl and are autoloaded.Kaz Kylheku2015-06-181-0/+30
| | | | | | | | | | | | | | | | | * lisplib.c (ver_set_entries, ver_instantiate, txr_case_set_entries, txr_case_instantiate): New static functions. (lisplib_init): Register new functions. * share/txr/stdlib/txr-case.txr: Reduced to a load for the corresponding .tl file, retained for backward compatibility. * share/txr/stdlib/ver.txr: Likewise. * share/txr/stdlib/txr-case.tl: New file, based on previous contents of corresponding .txr file. * share/txr/stdlib/ver.tl: Likewise.
* Adding anaphoric ifa macro.Kaz Kylheku2015-06-171-0/+16
| | | | | | | | | | | | | | | | | | | | * Makefile (install): Install .tl files present in stdlib directory. (INSTALL): Handle argument 2 being a list. * eval.c (load): New function. * eval.h (load): Declared. * lisplib.c (ifa_set_entries, ifa_instantiate): New functions to lazily load ifa.tl. (lisplib_init): Register new functions. * txr.c (stdlib_path): New variable.

| | | | | | | | | | | * lisplib.c (set_dlt_entries): New static function. (set_place_dlt_entries): Renamed to place_set_entries. Uses set_dlt_entries as subroutine. (place_instantiate): Argument changes from table to function, which is invoked to null out the hash entries. (dlt_register): New static function. (lisplib_init): Use dlt_register to register dynamic loading of places_tl.
* Adding pushnew.Kaz Kylheku2015-05-221-1/+1
| | | | | | * place.tl (pushnew): New macro. * lisplib.c (set_place_dlt_entries): Add pushnew.
* Represent place.tl more compactly in image.Kaz Kylheku2015-05-191-1/+1
| | | | | | | | | The contents of place.tl are now stored as a UTF-8 ordinary literal instead of a wide char literal. * Makefile (LISP_TO_C_STRING): Generate plain literal. * lisplib.c: Convert plain literal to string.
* * place.tl (define-modify-macro): New macro.Kaz Kylheku2015-05-131-0/+1
| | | | * lisplib.c (set_place_dlt_entries): Add define-modify-macro.
* Adding pset operator.Kaz Kylheku2015-05-091-1/+1
| | | | | | * place.tl (pset): New macro. * lisplib.c (set_place_dlt_entries): Add pset.
* * Makefile (LISP_TO_C_STRING): Strip comments, but not comment lines,Kaz Kylheku2015-05-071-1/+2
| | | | | | | | | | | | | | | | | | so line numbers don't change. * eval.c (eval_init): Fix registrations of lisp-parse and read. * lisplib.c (place_instantiate): Give name to parsed string stream using new lisp_parse argument. * parser.c (lisp_parse): Takes new argument to override name. * parser.h (lisp_parse): Declaration updated. * txr.c (txr_main): Call lisp_parse with four args, defaulting the new one. * txr.1: Documented new argument.
* New macro-based framework for assignment places.Kaz Kylheku2015-05-061-0/+83
The operators set, inc, dec, pop and others are now macros which generate code, rather than built-in special forms that use "C magic". Moreover, new such macros are easy to write, and several new ones are already available. Moreover, new kinds of assignable places are easy to create. * place.tl: New file. * lisplib.c, lisplib.h: New files. * Makefile (OBJS): New target, lisplib.o. (GEN_HDRS): New variable. (LISP_TO_C_STRING): New recipe macro, with rule. (clean): Remove generated headers named in $(GEN_HDRS). * eval.c (dec_s, push_s, pop_s, flip_s, del_s): Variables removed. (setq_s): New variable. (lookup_var, lokup_sym_lisp_1, lookup_var_l, lookup_fun, lookup_mac, lookup_symac, lookup_symac_lisp1): Trigger the delayed loading of libraries for undefined global symbols, and re-try the lookup. (op_modplace, dwim_loc, force_l): Static functions removed. (op_setq): New static function. (eval_init): Initialize setq_s; remove initializations of removed variables; remove registrations for op_modplace; add registration for sys:setq, sys:rplaca, sys:rplacd, sys:dwim-set and sys:dwim-del intrinsics. Call lisplib_init to initialize the dynamic library loading module. * lib.c (sys_rplaca, sys_rplacd): New functions, differing in return value from rplaca and rplacd. (ref, refset): Handle hash table. (dwim_set, dwim_del): New functions. * lib.h (sys_rplaca, sys_rplacd, dwim_set, dwim_del): Declared. * genvim.txr: Include place.tl in scan. * tests/010/seq.txr: The del operator test case no longer throws at run-time but at macro-expansion time, so the test case is simply removed. * tests/010/seq.expected: Updated output. * tests/011/macros-2.txr: Reset *gensym-counter* to zero, because the textual output of the test case includes gensyms, whose numberings fluctuate with the content of the new Lisp library material. * tests/011/macros-2.expected: Updated output.
