* Improving behavior of op and fixing a bug.Kaz Kylheku2013-10-061-17/+35
| | | | | | | | | | | | | | | | | | | | | Explicitly specifying @rest using (op ... . @rest) did not work at all. The then-func agument of iff and iffi may now be nil. * eval.c (format_op_arg): New static function. (transform_op): Handle dotted lists ending in @rest or @<num>. (supplement_op_syms): New static function. (expand_op): Add missing numeric arguments, so that all 1 through n are in the list. Trailing rest is now added under different conditions. * lib.c (do_iff): Give thenfun the same behavior on nil that elsefun enjoys. * txr.1: Updated.
* New feature: :vars argument in repeat and rep directives in an outputKaz Kylheku2013-10-061-5/+43
| | | | | | | | | | | | block, for specifying variables to include in iteration whose presence repeat is not able to deduce. * match.c (extract_bindings): New argument, vars, specifies additional variables to consider. (do_output_line, do_output): Process :vars argument of repeat and rep directive. * txr.1: Updated.
* Fix dates.txr-67Kaz Kylheku2013-07-131-1/+1

* Version 67Kaz Kylheku2013-07-131-0/+8
| | | | | | | txr.1: Documented line continuation for string literals, supported since Version 38 but not clarified properly. RELNOTES: Updated.
* * txr.1: Fix slipup, where call is referred to as funcall.Kaz Kylheku2013-07-121-1/+1

* Version 67Kaz Kylheku2013-07-121-2/+25
| | | | | | | | | | | | | | * txr.c (version): Bumped. * txr.1: Bumped version, set date and documented string-cmp. * configure (txr_ver): Bumped. * eval.c (eval_init): Forgotten string-cmp registered as intrinsic. * txr.vim: Highlighting for string-cmp. * RELNOTES: Updated.
* * match.c (require_s): New variable.Kaz Kylheku2013-06-111-3/+24
| | | | | | | | | | | | | | (v_require): New static function. (syms_init): Initialize require_s. (dir_tables_init): Add new entries into v_directive_table and h_directive_table for new require directive. * match.h (require_s): Declared. * txr.1: Added do and require directives to the directive summary section. Documented new require directive. Fixed int-str documentation to clarify that the radix is optional.
* * eval.c (eval_init): tok-str acquires new parameterKaz Kylheku2013-06-111-1/+8
| | | | | | | | * lib.c (tok_str): New parameter, keep_sep. * lib.h (tok_str): Declaration updated. * txr.1: Documentation for tok-str updated.
* * eval.c (eval_init): lazy-str's third argument is optional.Kaz Kylheku2013-06-111-13/+213
| | | | | | | | | | | | | | | | | | | Added lazy-stringp. Changing names of length-str-{gt,ge,lt,le} to be consistent with the >, >=, < and <= functions. * lib.c (lazy_stream_func): Greatly simplified implementation. The lazy list now continues by means of recursing via an optimized version of lazy_stream_cons called lazy_stream_cont. The environment structure is simplified to just hold the next item, rather than a pointless list. The pointless setting of lcons->lc.func to nil is also removed; this is always done by the caller. (lazy_stream_cont): New static function, similar to lazy_stream_cons, but optimized by not consing up a new function and new environment cell. (lazy_stream_cons): The environment for the update function is simplified to just a single cons. * txr.1: Documented lazy string functions and lazy-stream-cons.

The new behavior is more sensible and consistent with documentation. * txr.1: Typo fixed in related documentation.

(alist_nremove1): Use equal rather than eq. (merge): Bugfix: unnecessary consing caused by using append instead of nconc on list pieces that are already destructively chopped up. This has implications for the efficiency of sort over lists! (multi_sort_less): Implement key functions. (multi_sort): Interface change: arguments rearranged, and new argument to specify key functions. * lib.h (assoc, assq, assql, aconsq_new, aconsq_new_l): Declarations renamed.

| | | | | | | | | | | | | | | | | | | | | | | that popen accepts a complete command. We need something which accepts a program name, and a list of arguments, so that we don't have to assemble together a correctly quoted string. popen needs an alternative interface resembling execvp. * eval.c (eval_init): New intrinsic registered, open-pipe-args. * stream.c (struct stdio_handle): New member, pid. (stdio_stream_print): Print the pid, if it is nonzero. (pipevp_close): New close function. (pipe_close): If h->pid is nonzero, it's a new-style pipe, which must be closed with pipev_close.
