| | | | | | | | | * struct.c (struct_init): Register new functions. (struct_from_plist, struct_from_args): New functions. * struct.h (struct_from_plist, struct_from_args): Declared. * txr.1: Documented.

| | | | | | | | * eval.c (eval_init): Update registration of match-fun. * match.c (match_fun): Do defaulting on third and fourth arg. * txr.1: Documenation updated.
* Drop the annoying need for - for standard input.Kaz Kylheku2017-03-081-0/+18
| | | | | | | | | | | | | * match.c (open_data_source): If there is nothing in the files array and data is t (indicating a request to open a data source), then use standard input. Subject to the compatibility option. * Makefile (txr-manpage.html): Drop use of the txr - argument in rule recipe. * txr.1: Document that - isn't necessary. Added to compatibility notes.
* uref: the a.b.c syntax extended to .a.b.cKaz Kylheku2017-03-061-2/+140
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now it is possible to use a leading dot on the referencing dot syntax. This is the is the "unbound reference dot". It expands to the uref macro, which denotes an unbound-reference: it produces a function which takes an object as the argument, and curries the reference implied by the remaining arguments. * eval.c (uref_s): New global symbol variable. (eval_init): Intern uref symbol and init uref_s. * eval.h (uref_s): Declared. * lib.c (simple_qref_args_p): A qref expression is now also not simple if it contains an embedded uref, meaning that it cannot be rendered into the dot notation without ambiguity. (obj_print_impl): Support printing (uref a b c) as .a.b.c. * lisplib.c (struct_set_entries): Add uref to the list of autoload triggers for struct.tl. * parser.l (DOTDOT): Consume any leading whitespace as part of recognizing the DOTDOT token. Otherwise the new rule for UREFDOT, which matches (mandatory) leading space will take precedence, causing " .." to be scanned wrong. (UREFDOT): Rule for new kind of dot token, which is preceded by mandatory whitespace, and isn't consing dot (which has mandatory trailing whitespace too, matched by an earlier rule). * parser.y (UREFDOT): New token type. (i_dot_expr, n_dot_expr): New grammar rules. (list): Handle a leading dot on the first element of a list as a special case. Things are done this way because trying to work a UREFDOT into the grammar otherwise causes intractable conflicts. (i_expr): The ^, ' and , punctuators are now followed by an i_dot_expr, so that the expression can be an unbound dot. (n_expr): Same change as in i_expr, but using n_dot_expr. Plus new UREFDOT n_expr production. * share/txr/stdlib/struct.tl (uref): New macro. * txr.1: Documented.

* doc: block syntax horizontal and vertical.Kaz Kylheku2017-02-261-0/+26
| | | | | | * txr.1: Document that block syntax can be horizontal or vertical, and likewise that the accept and fail directives can be in horizontal or vertical context.
* doc: don't refer to BLOCKS section.Kaz Kylheku2017-02-261-6/+6
| | | | | * txr.1: Multiple places were referring to a section called BLOCKS. It is called Blocks.
* doc: print methods print, not pretty-print.Kaz Kylheku2017-02-261-1/+1
| | | | | | * txr.1: Fix misleading text which says that print methods are called to pretty-print objects. They are called for all printing: regular or pretty.
* New floor-rem, ceil-rem and round-rem.Kaz Kylheku2017-02-261-9/+23
| | | | | | | | | | | | * arith.c (trunc_rem): Move function to below round function. Make second argument optional, defaulting to one. (floor_rem, ceil_rem, round_rem): New functions. * eval.c (eval_init): Registration of trunc-rem altered for optional argument. New registrations for floor-rem, ceil-rem, round=rem. * txr.1: Documented for new functions folded with trunc-rem.
* Second argument optional in trunc.Kaz Kylheku2017-02-251-74/+84
| | | | | | | | | | | | | | * arith.c (trunc1): New static function. (trunc): Detect a missing second argument and call func1. * eval.c (eval_init): Update registration of trunc intrinsic to make second arg optional. * txr.1: Describe optional argument of trunc. Trunc documentation is merged with the floor, ceil and round section. The mod and trunc-rem functions are split off into their own sections, leaving the / function described by itself. The documentation of / is substantially revised.
* doc: horizontal-vertical issues in block and accept.Kaz Kylheku2017-02-251-0/+44
| | | | | | | * txr.1: Document what happens when a vertical block catches a horizontal accept, a horizontal block catches a vertical accept, or a horizontal block catches a horizontal accept from a different line.

* Use non-hacky representation for deferrable warnings.Kaz Kylheku2017-02-101-20/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Deferrable warnings now get their own subtype, defr-warning. The tag is a regular argument: no funny dotted argument list. * eval.c (eval_defr_warn): Throw new style deferrable warning. (me_op, no_warn_expand): Catch defr-warning rather than warning. Use uw_muffle_warning to suppress it. (gather_free_refs): Parse new representation of deferrable warning. (expand_with_free_refs): Catch defr-warning rather than warning. * lib.c (defr_warning_s): New symbol variable defined. (obj_init): Initialize defr_warning_s. * lib.h (defr_warning_s): Declared. * share/txr/stdlib/error.tl (compile-defr-warning): Throw new-style deferrable warning. * unwind.c (uw_muffle_deferrable_warning): Function removed. (uw_throw): Bugfix: handle warnings by checking by subtype rather than exactly for the warning type. Distinguish deferrable warnings by subtype rather than argument list shape. (uw_defer_warning): Take the new style args and reconstruct the (msg . tag) representation for a deferred warning, so the other functions don't have to change. (uw_late_init): Register defr-warning as exception subtype of warning. * unwind.h (uw_muffle_deferrable_warning): Decl removed. * txr.1: Adjusted all documentation touching on the subject of the representation of deferrable warnings.
* Better way for releasing deferred warnings.Kaz Kylheku2017-02-101-4/+17
| | | | | | | | | | | | | | | | | | | | We should be re-throwing deferred warnings as ordinary warnings, not dumping them to a stream. * eval.c (eval_exception): Use uw_release_deferred_warnings instead of uw_dupm_deferred_warnings. (load): Likewise. * parser.c (read_eval_ret_last): Likewise. * txr.c (txr_main): Likewise. * unwind.c (uw_release_deferred_warnings): New function. * unwind.h (uw_release_deferred_warnings): Declared. * txr.1: Documented release-deferred-warnings and updated documentation for dump-deferred-warnings.

* New catch*, giving access to exception symbol.Kaz Kylheku2017-01-251-1/+15
| | | | | | | | | | | | | | | | | | * eval.c (op_catch): The sys:catch operator now passes the exception symbol as the first argument of each clause. This means the catch macro must be adjusted. * share/txr/stdlib/except.tl (catch): Macro now inserts a gensym dummy first argument into each clause to take the symbol passed by the sys:catch operator. (catch*): New macro, which is identical to the previous catch macro, and thus exposes the symbol passed as the first argument. * txr.1: Documented catch*. * tests/012/struct.tl: Some gensym numbers need adjusting in one test case.
