* * eval.c (plus_s, prof_s): New symbol global variables.Kaz Kylheku2014-03-121-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (op_prof, me_pprof): New static functions. (eval_init): Intern prof symbol, store in prof_s. Captured interned + symbol in plus_s. Register prof operator and pprof macro. * gc.c (gc_bytes): New global variable. (more): Use nse function chk_malloc_gc_more instead of chk_malloc. (make_obj): Increment gc_bytes. * lib.c (malloc_bytes): New global variable. (chk_malloc, chk_realloc): Increment malloc_bytes. (chk_calloc): Bugfix: incorrect size in recursion into oom_realloc. Incorrect calculation of malloc_high_bound. Increment malloc_bytes. (chk_malloc_gc_more): New function. * lib.h (alloc_bytes_t): New typedef. (malloc_bytes, gc_bytes): Declared. (chk_malloc_gc_more): Declared. * stream.c (format_s): New symbol global. (stream_init): format_s inited. format_s used to register formatv function. * stream.h (format_s): Declared. * txr.1: Documented prof and pprof. * genvim.txr: Recognize reg_fun calls with intern followed by a preceding assignment or other syntax. * txr.vim: Updated.
* * lib.c (upop): New function.Kaz Kylheku2014-03-071-0/+1
| | | | | | | | | | | | | | * lib.h (upop): Declared. * txr.c (txr_main): Two bugfixes. One is that the argument - was being pushed back twice resulting in *args* being ("-" "-"). This is because the option processing loop checked for "-" and pushed it back into args, and then some logic after the loop pushed arg back into args again. But, these pushes were wrong because they push back a different cons cell; we would like to be able to do (ldiff *full-args* *args*). This is solved by upop, which provides one element of undo. After upop, we can restore the prior list from the undo save location.
* * lib.c (assert_s): New global variable.Kaz Kylheku2014-03-061-1/+1
| | | | | | | | | | | | | | | (obj_init): Intern assert symbol, store in assert_s. * lib.h (assert_s): Declared. * match.c (typed_error, v_assert, h_assert): New static functions.

* * arith.c (logten): New function.Kaz Kylheku2014-03-041-0/+1
| | | | | | | | * eval.c (eval_init): logten registered as intrinsic. * lib.h (logten): Declared. * txr.1: Documented.
* New quasiquote idea: let's have two quasiquote macros sharing oneKaz Kylheku2014-03-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | expander. One macro based on sys:qquote, sys:unquote and sys:splice, and the other based on qquote, unquote and splice in the user package. The read syntax puts out the sys: one. * eval.c (expand_qquote): Takes three additional arguments: the qquote, unquote and splice symbols to recognize. The invalid splice diagnostic is adjusted based on which backquote we are expanding. (me_qquote): Look at the symbol in the first position of the form and then expand either the internal quasiquote macro or the public one, passing the right symbols into expand_qquote. (eval_init): Register error-throwing stub functions for the sys_qquote_s, sys_unquote_s and sys_splice_s symbols. Register a macro for sys_qquote_s. * lib.c (sys_qquote_s, sys_unquote_s, sys_splice_s): New symbol variables. (obj_init): Initialize new variables. Change qquote_s, unquote_s and splice_s to user package. (obj_print, obj_pprint): Convert only sys_qquote_s, sys_unquote_s and sys_splice_s to the read syntax. The quote_s, unquote_s and splice_s symbols are not treated specially. * lib.h (sys_qquote_s, sys_unquote_s, sys_splice_s): Declared. * parser.y (n_expr): Use sys_qquote_s, sys_unquote_s and sys_splice_s rather than qquote_s, unquote_s and splice_s. (unquotes_occur): Likewise. * txr.1: Documented.
* Turn *gensym-counter* into proper special variable.Kaz Kylheku2014-02-281-1/+3
| | | | | | | | | | | | | | | | | * eval.c (eval_init): Save *gensym-counter* symbol in gensym_counter_s symbol variable right after interning, and use zero as the inital value rather than the gensym_counter variable which is removed now. * lib.c (gensym_counter_s): New symbol variable. (gensym_counter): Variable removed. (gensym): Slight refactoring to avoid a double variable lookup. Also, for generational GC correctness, use the set macro to update it, since the variable could live inside heap object and the counter could overflow to bignums which are heap objects. (obj_init): Remove initialization of gensym_counter. * lib.h (gensym_counter_s): Declared. (gensym_counter): Declaration removed, replaced by macro.
* Change in the design of how special variables work, to fix the brokenKaz Kylheku2014-02-281-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | re-binding. C code now has to go through the dynamic environment lookup to access things like *random-state*, or *stdout*. As part of this, I'm moving some intrinsic variable and function initializations out of eval.c and into their respective modules. Macros are are used to make global variables look like ordinary C variables. This is very similar to the errno trick in POSIX threads implementations. * eval.c (looup_var, lookup_var_l): Restructured to eliminate silly goto, the cobjp handling is gone. (reg_fun, reg_var): Internal function becomes external. reg_var registers a simple cons cell binding now, without any C pointer tricks to real C global variables. (c_var_mark): Static function removed. (c_var_ops): Static struct removed. (eval_init): Numerous initializations for streams, syslog, rand, signals and others moved to their respective modules. The new symbol variables user_package_s, keyword_package_s and system_package_s are interned here, and the variables are created in a special way. * eval.h (reg_var, reg_fun): Declared. * gc.c (prot1): Added assert that the loc pointer isn't null. This happened, and blew up during garbage collection. * lib.c (system_package, keyword_package, user_package): Variables removed these become macros. (system_package_var, keyword_package_var, user_package_var): New global variables. (system_package_s, keyword_package_s, user_package_s): New symbol globals. (get_user_package, get_system_package, get_keyword_package): New functions. (obj_init): Protect new variables. Initialization order of modules tweaked: the modules sig_init, stream_init, and rand_init are moved after eval_init because they register variables. * lib.h (keyword_package, system_pckage, user_package): Variables turned into macros. (system_package_var, keyword_package_var, user_package_var): Declared. (system_package_s, keyword_package_s, user_package_s): Declared. (get_user_package, get_system_package, get_keyword_package): Declared. * rand.c (struct random_state): Renamed to struct rand_state to avoid clash with new random_state macro. (random_state): Global variable removed. (random_state_s): New symbol global. (make_state, rand32, make_random_state, random_fixnum, random): Follow rename of struct random_state.
* * lib.c (copy): New function.Kaz Kylheku2014-02-271-0/+1
| | | | | | | | * lib.h (copy): Declared. * eval.c (eval_init): Registered copy function as intrinsic. * txr.1: Added missing documentation for length. Documented copy.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | with just using the == operator. Removing cobj_equal_op since it's indistinguishable from eq. Streamlining missingp and null_or_missing_p. * eval.c (transform_op): eq to ==. (c_var_ops): cobj_equal_op to eq. * filter.c (trie_compress, trie_lookup_feed_char, filter_string_tree, html_hex_continue, html_dec_continue): eq to ==. * hash.c (hash_iter_ops): cobj_equal to eq. * lib.c (countq, getplist, getplist_f, search_str_tree, posq): eq to ==. (cobj_equal_op): Function removed. * lib.h (cobj_equal_op): Declaration removed. (missingp): Becomes a simple macro that yields a C boolean instead of t/nil val, because it's only used that way. (null_or_missing_p): Becomes inline function returning int. * match.c (v_output): eq to ==. * rand.c (random_state_ops): cobj_equal_op to eq. * regex.c (char_set_obj_ops, regex_obj_ops): cobj_equal_op to eq. (reg_derivative): Silly if3 expression replaced by null. (regexp): Redundant if2 expression wrapped around eq removed. * stream.c (null_ops, stdio_ops, tail_ops, pipe_ops, string_in_ops, byte_in_ops, string_out_ops, strlist_out_ops, dir_ops, cat_stream_ops): cobj_equal_op to eq. * syslog.c (syslog_strm_ops): cobj_equal_op to eq.
* The C function nullp is being renamed to null, and the rarelyKaz Kylheku2014-02-221-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | used global variable null which holds a symbol becomes null_s. A new macro called nilp is added that more efficiently checks whether an object is nil, producing a C boolean value rather than t or nil. Most of the uses of nullp in the codebase just become the more streamlined nilp. * debug.c (show_bindings): nullp to nilp * eval.c (lookup_var, lookup_var_l, lookup_fun, lookup_sym_lisp1, do_eval, expand_qquote, expand_quasi, expand_op): nullp to nilp. (op_modplace): nullp to null. (eval_init): Update registration of null and not from C function nullp to null. * filter.c (trie_compress, html_hex_continue): nullp to nil.

(lazy_flatten_scan, chainv, lazy_str, lazy_str_force_upto, obj_print, obj_pprint): nullp to nilp. (obj_init): null to null_s; nullp to null. * lib.h (null): declaration changed to null_s. (nullp): Inline function renamed to null. (nilp): New macro. * match.c (do_match_line): nullp to nilp. * rand.c (make_random_state): Likewise. * regex.c (compile_regex): Likewise.

| | | | | | | | | | | | | | | | | | | | | | | | | | | that return the new or old cons cell rather than a pointer to its cdr field. * eval.c (transform_op): use of acons_new_l replaced with acons_new_c. * hash.c (struct hash): acons_new_l_fun member replaced with acons_new_c_fun. (make_hash, make_similar_hash): initialize acons_new_l_fun member using either acons_new_c or aconsql_new_c. (gethash_l): function becomes an inline in hash.h. (gethash_c): new function, based on gethash_l. (inhash, gethash_n): updated w.r.t struct hash change. * hash.h (gethash_c): declared.

Supports sequences and hashes as functions. Error messages fixed not to refer to "funcall". (funcall, funcall1, funcall2, funcall3, funcall4): Do not throw exception if fun is not of FUN type; instead, delegate to generic_funcall.

(do_txeval, v_collect): Slightly revise unwinding macrology with help of new macros to avoid mixing declarations and statements. (spec_bind): Removed spurious semicolon from macro expansion. (v_gather): Reorder two lines to avoid mixed decls and statements.
