* awk macro: provide name of current input via fname.Kaz Kylheku2017-01-261-0/+24
| | | | | | | | | | * share/txr/stdlib/awk.tl (sys:awk-state): New slot, file-name. (sys:awk-state loop): Set file-name from current input name, or else from the stream name property if the current input is a stream object. (sys:awk-mac-let): New awk macro, fname. * txr.1: Documented fname.

| | | | | | | | | | * share/txr/stdlib/build.tl (sys:list-builder-macrolets): Function renamed to sys:list-builder-flets. Builds local functions instead of macrolets. (build): Follow rename of sys:list-builder-macrolets. * txr.1: Documentation updated and example added of use of add as a higher order function.
* New handle* macro, analogous to catch*.Kaz Kylheku2017-01-251-1/+15
| | | | | | | | | | | * share/txr/stdlib/except.tl (sys:expand-handle): New function. (handle): Use sys:expand-handle to expand arguments. The previously unused :whole form argument is now put to use, and correctly captured using :form rather than :whole. (handle*): New macro. * txr.1: Documented.

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.

* Bugfix: repeated expansion of catch unstable.Kaz Kylheku2016-12-311-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out we have a silly problem: catch is a special operator, which undergoes a macro-like expansion which alters its syntax, but uses the same operator symbol. We turn catch into a macro which expands to a sys:catch operator. * eval.c (sys_catch_s): New symbol variable. (expand_catch): Function now expands sys:catch forms without altering any syntax. (do_expand): Check for sys:catch rather than catch. Call expand_catch differently: it takes the form now instead of just the arguments, so it can return the original form if no expansion takes place. (eval_init): Initialize sys_catch_s variable. Change registration of op_catch to sys:catch symbol. * lisplib.c (except_set_entries): Add catch to the list of autoload symbols for except.tl. * share/txr/stdlib/except.tl (catch): New macro for transforming catch to sys:catch. * txr.1: Reclassify catch operator as a macro.

* doc: extended dialect notes about exceptions.Kaz Kylheku2016-12-221-0/+153
| | | | | * txr.1: New section comparing TXR Lisp exceptions with CL conditions, with a contrasting example.
* Last var may be omitted in iflet/whenlet/condlet.Kaz Kylheku2016-12-221-0/+28
| | | | | | | | * eval.c (me_iflet_whenlet): Allow the last binding to be (init-form) instead of (sym init-form), for situations in which sym is never used. * txr.1: Documented.
* doc: refer to sort function out of List Sorting.Kaz Kylheku2016-12-221-0/+18
| | | | | | * txr.1: The List Sorting section looks as if it describes all the support there is for sorting. Add references pointing to sort under Sequence Manipulation.

* New function: find-frames.Kaz Kylheku2016-12-201-1/+10
| | | | | | | | | | | | | * unwind.c (uw_find_frames_impl): New static function, made from uw_find_frame. (uw_find_frame): Reduced to wrapper around uw_find_frames_impl. (uw_find_frames): New function. (uw_late_init): Register find-frames intrinsic. * unwind.h (uw_find_frames): Declared. * txr.1: Documented.
