* Version 170.txr-170Kaz Kylheku2017-02-281-2/+2
| | | | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise. * txr.vim, tl.vim: Regenerated.
* doc: give some examples of accept interaction.Kaz Kylheku2017-02-271-0/+101
| | | | | * txr.1: Example given for how @(accept) interacts with @(next) and with the function call mechanism.
* doc: horizontal trailer.Kaz Kylheku2017-02-261-0/+26
| | | | | * txr.1: Add missing documentation of the existence of horizontal @(trailer) syntax.
* 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 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.
* doc: special interactions with accept.Kaz Kylheku2017-02-251-17/+123
| | | | | | * txr.1: Documenting all the special interactions with accept that have been recently added: next directive, functions, finally.

| | | | | | | | | | | * eval.c (eval_init): Register rassoc and rassql intrinsics. * lib.c (rassoc, rassql): New functions. * lib.h (rassoc, rassql): Declared. * txr.1: Documented rassoc and rassql, with small fixes to assql and assoc.
* 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.
* doc: dotimes heading formatting.Kaz Kylheku2017-02-071-1/+2

* Version 168.txr-168Kaz Kylheku2017-02-021-2/+2

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.
