* Compatibility <= 107 allows redefinition of builtins.Kaz Kylheku2015-08-241-1/+6
| | | | | | | | * eval.c (builtin_reject_test): Suppress the diagnostic against redefinition of built-in macros and operators if the compatibility is 107 or lower. The rejection appeared in 108. * txr.1: Document this compatibility behavior.
* New function: shuffle.Kaz Kylheku2015-08-241-0/+21
| | | | | | | | * eval.c (eval_init): Register shuffle as intrinsic. * lib.c (shuffle): New function. * lib.h (shuffle): Declared.
* Use of new args for function calls in interpreter.Kaz Kylheku2015-08-231-12/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * args.c (args_copy_to_list): New function. * args.h (ARGS_MIN): New preprocessor symbol. (args_add_list): New inline function. (args_copy_to_list): Declared. * debug.c (debug): Args in debug frame are now struct args *. Pull them out nondestructively for printing using args_copy_to_list. * eval.c (do_eval_args): Fill struct args argument list rather than returning evaluated list. Dot position evaluation is handled by installing the dot position value as args->list. (do_eval): Allocate args of at least ARGS_MAX for the call to do_eval_args. Then use generic_funcall to invoke the function rather than apply. (eval_args_lisp1): Modified similarly to do_eval_args. (eval_lisp1): New static function. (expand_macro): Construct struct args argument list for the sake of debug_frame. (op_dwim): Allocate args which are filled by eval_args_lisp1, and applied to the function/object with generic_funcall. The object expression is separately evaluated with eval_lisp1. * match.c (h_fun, v_fun): Construct struct args arglist for the sake of debug_frame call. * unwind.c (uw_push_debug): args argument becomes struct args *. * unwind.h (struct uw_debug): args member becomes struct args *. (uw_push_debug): Declaration updated. * txr.1: Update documentation about dot position argument in function calls. (list . a) now works, which previously didn't.
* Clarification about @rest in do/op syntax.Kaz Kylheku2015-08-231-9/+20
| | | | | | * txr.1: Make it clear that @rest is not inserted if meta-numbers or @rest is present. Move example to the end.
* Missing notes about global lexical variables.Kaz Kylheku2015-08-201-8/+43
| | | | | | * txr.1: Note that TXR Lisp has global lexicals, and that some library variables are examples of such, and that defparm is defparameter in CL.
* Wording in description of quasiquote.Kaz Kylheku2015-08-201-2/+2
| | | | | * txr.1: An unquote's evaluation should be contrasted with the quasiquote's suppression of it, not with the quote.
* Version 113.txr-113Kaz Kylheku2015-08-141-2/+2
| | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise.
* Troff formatting macros must not generate control sequences.Kaz Kylheku2015-08-191-4/+4
| | | | | | | | Reported by Dave Love. * txr.1 (cod1, cod2, meti, TP*): When inserting material at the start of a line, add the \& zero width character, so the line isn't interpreted as a control sequence.
* Fix man page markup errors.Dave Love2015-08-171-22/+22
| | | | | * txr.1: Numerous misspellings of macro names are repaired.
* Improved wording about auto-loading.Kaz Kylheku2015-08-161-5/+6
| | | | | * txr.1: In the stdlib variable description, rewrote the text describing the macro-time autoloading scenario.
* Allow slashes in regex passed to regex-parse.Kaz Kylheku2015-08-151-3/+32
| | | | | | | | | | | * parser.l (SREGEX): New start state, for stand-alone regex parsing. (grammar): All REGEX state rules are active in the SREGEX state also. The rule for the / character returns a REGCHAR if in the SREGEX state, so it is treated as an ordinary character. * txr.1: Updated regex-parse documentation about the treatment of the slash. Also added notes about double escaping when a string literal is passed to regex-parse.
* Formatting fix under clamp function.Kaz Kylheku2015-08-141-1/+1
| | | | * txr.1: .meta -> .metn
* Version 112.txr-112Kaz Kylheku2015-08-141-2/+2
| | | | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise. * tl.vim, txr.vim: Regenerated.
* New function, clamp.Kaz Kylheku2015-08-131-0/+38
| | | | | | | | | | * eval.c (eval_init): Register clamp as intrinsic function. * lib.c (clamp): New function. * lib.h (clamp): Declared. * txr.1: Documented.
* Observe display width in format.Kaz Kylheku2015-08-131-3/+23
| | | | | | | | | | | | | Take into account string display width in field trimming and padding calculations, including situations where only half a character fits. * stream.c (calc_fitlen): New function. (vformat_str): Revised to use calc_fitlen. If calc_fitlen indicates that there is no trimming or padding, then use put_string rather than put_char. * txr.1: Update description of format with regard to use of dispaly width in field calculations.
* New display-width function.Kaz Kylheku2015-08-131-0/+27
| | | | | | | | | | * eval.c (eval_init): Register display-width intrinsic. * lib.c (display_width): New function. * lib.h (display_width): Declared. * txr.1: Documented display-width.
* Floating-point constant tightening.Kaz Kylheku2015-08-121-3/+4
| | | | | | | | | | | | | * parser.l (grammar): Change order of rule which recognizes FLODOT with a one-character trailing context other than a dot, and the rule which diagnoses trailing junk. The issue is that this order gives the wrong interpretation to 123.E, treating it as 123. followed by E rather than trailing junk, like in the case of 123.0E or 123.B. * txr.1: Adding the valid example 1.E5. Removing references to dot as consing dot. Fixed documentation which says that 1.E is 1 followed by a consing dot and E. The wrong behavior in fact produced 1.0 followed by E. No consing dot semantics.
* Revision to .. syntax.Kaz Kylheku2015-08-121-21/+15
| | | | | | | | | | | | | * parser.y (r_exprs, n_expr): Move the DOTDOT syntactic sugar rule from r_exprs to n_expr, where it is much simpler. This also means that the a..b syntax is now an expression by itself; it need not be enclosed in a list. The DOTDOT operator is made right associative; or rather its existing %right declaration is now activated. * txr.1: Remove documentation stating that the .. notation must be used in a list, and not in the dotted position of an improper list. Document the behavior in the dotted position, and document right associativity.
* Dot with no whitespace generates qref syntax.Kaz Kylheku2015-08-101-0/+41
| | | | | | | | | | | | | | | | | | | | | | | a.b.(expr ...).c -> (qref a b (expr ...) c) Consing dot requires whitespace. * eval.c (qref_s): New symbol global variable. (eval_init): Initialize qref_s. * eval.h (qref_s): Declared. * parser.l (REQWS): New pattern definition, required whitespace. (grammar): New rules to scan CONSDOT (space required on both sides) and LAMBDOT (space required after). * parser.y (CONSDOT, LAMBDOT): New token types. (list): (. n_expr) rule replaced with LAMBDOT and CONSDOT. (r_exprs): r_exprs . n_expr consing dot rule replaced with CONSDOT. (n_expr): New n_expr . n_expr rule introduced here for producing qref expressions. (yybadtoken): Handle CONSDOT and LAMBDOT. * txr.1: Documented qref dot.

(debug_set_state, debug_restore_state): Declared, and defined as dummy macros in non-debug-support build. * lisplib.c (opt_dbg_autoload): New global variable. (lisplib_try_load): Disable or enable debugging around library loading based on opt_dbg_autoload option. * lisplib.h (opt_dbg_autoload): Declared. * txr.c (help): List --debug-autoload option.

(mark_special): Return val rather than void, since it's hoisted into Lisp domain now with func_n1. (op_defvar): Renamed to op_defvarl, and doesn't call mark_special. defvarl is now the special form for defining variables, and special marking is an embellishment added by macros. (me_defparm): Renamed to me_def_variable. Handles defvar, defparm and defparml. (do_expand): Expand defvarl, rather than defvar. (eval_init): Intern defvarl, defparm, defparml and mark-special symbols, and initialize corresponding globals. Register defvarl special operator, retiring defvar.
