* * eval.c (not_null): New static function.Kaz Kylheku2014-06-171-3/+30
| | | | | | | | (eval_init): Use null_f in existing registration of null and not. Add registration for not_null as "true", and for null_f as "false". * txr.1: Documented true and false.
* * eval.c (eval_init): register tuples as intrinsic.Kaz Kylheku2014-06-171-0/+33

* * lib.c (obj_print): Render character DC00 as "pnul".Kaz Kylheku2014-06-151-2/+22
| | | | | | | | | | | | | Clean up code which chooses rendering for characters. Print C0 and C1 control characters, as well as D800-DFFF, FFFE and FFFF and characters above FFFF using hex; others are printed using the #\<char> notation. * parser.y (char_from_name): map "pnul" to DC00. * txr.1: Documented pnul, clarified character printing rules, and added a cautionary note about possible ambiguity in printing.
* * eval.c (eval_init): Register pos_max, pos_min, find_max,Kaz Kylheku2014-06-151-0/+81

* * eval.c (eval_init): Change registration of string_cmpKaz Kylheku2014-06-101-19/+47
| | | | | | | | | | | | | | | | | | | to cmp_str. Add registrations for str_eq, str_lt, str_gt, str_le, and str_lt. * lib.c (string_cmp): Name changes to cmp_str, and the function fixed so that it actually works. The name change doesn't affect anyone because the function was too broken to use due to the incorrect type dispatch. (string_lt): Name changes to str_lt. (str_eq, str_gt, str_le, str_ge): New functions. * lib.h (string_cmp, string_lt): Declarations renamed. (str_eq, str_gt, str_le, str_ge): New declarations. * txr.1: Document string-cmp to cmp-str rename, that string-lt is deprecated, and the new str<, str>, str>=, str<= and str= functions.

(stdio_put_string, stdio_put_char, stdio_put_byte): Remove update of output_produced. * stream.h (output_produced): Declaration removed. * txr.1: Documentation updated. * txr.c (txr_main): Option 'b' does nothing. 'B', 'l', 'a', and '--lisp-bindings' set opt_print_bindings to 1. * txr.h (opt_nobindings): Declaration removed. (opt_print_bindings): Declared. * unwind.c (uw_throw): When exiting due to a query error or file error, print false when opt_print_bindings is true.

| | | | | | | | | | | | | | | | | | | | | | | | | | namely that empty strings and vectors are not nil. The nullify function is introduced. It is also exposed to users, as is the existing make_like function. * eval.c (mapcarv, mappendv, lazy_mapcar, lazy_mapcarv): Use nullify to handle non-list inputs correctly. (eval_init): Registering make_like and nullify as intrinsics. * lib.c (copy_list, to_seq, list_collect_nconc, list_collect_append, reverse, lazy_appendv_func, lazy_appendv, ldiff, memq, memql, memqual, remq, remql, remqual, remove_if, keep_if, rem_lazy_rec, remq_lazy, remql_lazy, remqual_lazy, remove_if_lazy, keep_if_lazy, countqual, countql, countq, count_if, some_satisfy, all_satisfy, none_satisfy, do_chain, chainv, do_and, andv, do_or, orv, cat_vec, assoc, assql, mapcar, mapcon, mappend, sort, multi_sort, find, find_if, posqual, posql, posq, pos, pos_if, set_diff, search): Use nullify for correctness.

| | | | | | | | | | | | | | | | * parser.l (WLIT): New exclusive start state. Extend lexical grammar to transition to WLIT state upon the #" or #*" sequence which kicks off a word literal, and in that state, piecewise lexically analyze the literal, mostly by borrowing rules from other literals. * parser.y (WORDS, WSPLICE): New tokens. (n_exprs): Integrate splicing form of word list literal syntax. (n_expr): Integrate non-splicit for of word list literal syntax. (litchars): Propagate line number info.

* Document that leading whitespace before a backslash lineKaz Kylheku2014-03-151-2/+15

* * parser.l: Bugfix. When handling a backslash-newline continuationKaz Kylheku2014-03-151-2/+5
| | | | | | | | | | | | | | | | in the SPECIAL, NESTED and BRACED states, do not pop the state in all three, only in SPECIAL (to terminate the @\ continuation). * txr.1: Eliminate wrong claim that string literals do not split across lines, which is directly contradicted two paragraphs later. Document that quasiliterals also split. * genvim.txr (txr_regex, txl_regex): These definitions change from "syn match" to "syn region" so that the backslash-newline continuation can be properly handled. (txr_string, txr_quasilit): Correctly handle split literals. * txr.vim: Regenerated.

| | | | | | | | | | | | | | | * rand.c (make_random_state): Do argument defaulting on seed. Also, mix getpid() into the seed. (random_fixnum): Bugfix: do proper defaulting on optional agument, rather than relying on nil. (random): Fix 2014-02-05 regression. This was totally broken, ignoring the random state passed in and using the global random state. This function must only use the state passed in; there is no defaulting to the global random state. * txr.1: Documenting that seed is optional in make-random-state. Describing what guarantees can be expected with regard to calls made close together temporally.

* * stream.c (pipe_close): Restructured the function a bit.Kaz Kylheku2014-03-101-1/+18
| | | | | | | | | | Do not throw exceptions for normal process terminations, only for abnormal ones (terminated by a signal). Return the termination status instead of just t. * txr.1: Fixed the neglected documentation of the optional boolean argument of close-stream. Described the behaviors with regard to pipes in more detail.

| | | | | | | | | | | | precision (i.e. given by *). The simplest way to do this is to add a state vf_star which is similar to vf_digits, and reuses much of the logic via a goto. Fixing forgotten --fmt (push back char) when moving from vf_precision to vf_spec state due to unhandled character. Also, allowing a leading zero before a precision given as * so that computed precisions can be combined with zero padding. * txr.1: Documented leading zero better so it is clear it combines with *.

Recognize the ^ character as a token in the NESTED state. * lib.c (obj_print, obj_pprint): Render sys:qquote as ^. * parser.y (choose_quote): Function removed. (n_expr): Recognize '^' as quasiquote. Removed all the "smart quote" hacks that try to make quote behave as quote or quasiquote, or try to cancel out unquotes and quotes. * tests/009/json.txr: Fixed to ^ quasiquote. * tests/010/reghash.txr: Likewise. * tests/011/macros-2.txr: Likewise. * tests/011/mandel.txr: Likewise. * tests/011/special-1.txr: Likewise. * txr.1: Updated docs. * genvim.txr: Revamped definitions for txr_ident and txl_ident so that unqualified identifiers cannot start with # or ^, but ones with @ or : in front can start with these characters. * txr.vim: Regenerated.
