* The identity function gets an alias: use.Kaz Kylheku2016-01-132-1/+23
| | | | | | * eval.c (eval_init): Register "use" as alias for identity. * txr.1: Documented use function.
* Pastes produced using :read are now numbered.Kaz Kylheku2016-01-131-4/+6
| | | | | | | | * parser.c (read_eval_read_last): New argument: counter. Incorporate counter into name of stream. (repl): Pass prev_counter into read_eval_read_last so the paste inherits the line number of the :read command.
* Support crypt function.Kaz Kylheku2016-01-133-0/+73
| | | | | | | | | | * configure: Check for availability of crypt, and what library must be used. * sysif.c (crypt_wrap): New static function. (sysif_init): Register crypt intrinsic. * txr.1: Documented crypt.
* Don't clobber conf_ldflags.Kaz Kylheku2016-01-131-1/+1
| | | | | * configure: the do-we-need-to-set-stack-size test shouldn't overwrite conf_ldflags, but add to it.
* Support extra linker flags.Kaz Kylheku2016-01-131-1/+1
| | | | | * Makefile (EXTRA_LDFLAGS): New variable, interpolated into LDFLAGS.
* Version 131.txr-131Kaz Kylheku2016-01-124-4/+32
| | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise.
* Fix broken print of semicolon after ctrl char.Kaz Kylheku2016-01-121-1/+1
| | | | | | | | * lib.c (out_str_char): If semi-flag is true, we must issue a semicolon not only when the next character is a hex digit, but also when it is a semicolon, so that "\x1F;;" isn't rendered as "\x1F;" where the semicolon character has disappeared.
* Regex printing not escaping [ and ].Kaz Kylheku2016-01-121-1/+2
| | | | | * regex.c (print_rec): Handle '[' and ']' in backslash-adding switch.
* Print control chars in regexes using \x.Kaz Kylheku2016-01-123-54/+72
| | | | | | | | | | | | | | | | | | | | * lib.c (out_str_char): Static function becomes extern. * lib.h (out_str_char): Declared. * regex.c (puts_clear_flag, putc_clear_flag): New static functions. (print_class_char): Take semicolon flag argument. Use out_str_char to render characters not escaped locally. Clear the semicolon flag. (paren_print_rec): Take semicolon flag argument, and pass it down. Clear it when printing parentheses. (print_rec): Take semicolon flag argument, and pass down to lower level functions. Use putc_clear_flag and puts_clear_flag instead of put_string and put_char. Use out_str_char for char object not esaped locally. (regex_print): define semi_flag and pass it down to print_rec.
* Pretty-print DEL and U+DCxx str char using \xHEX.Kaz Kylheku2016-01-121-1/+1
| | | | | | * lib.c (out_str_char): Don't print all characters above space as themselves. Treat 7F and U+DCxx as control chars to be printed using hex escape.
* regex_print: [ and ] in char class must be escaped.Kaz Kylheku2016-01-121-1/+1
| | | | * regex.c (print_class_char): Add missing character cases.
* Remove redundant assert in mem allocation functions.Kaz Kylheku2016-01-101-3/+0
| | | | | | * lib.c (chk_strdup, chk_strdup_utf8, chk_copy_obj): No need to assert !async_sig_enabled since the lower level chk_malloc or chk_malloc does it.
* Reduce scope of variable in cat_str.Kaz Kylheku2016-01-101-2/+2
| | | | | * lib.c (cat_str): Unnecessarily scoped len variable moves to inner scope.
* New internal function scat: variable arg cat_str.Kaz Kylheku2016-01-104-7/+88
| | | | | | | | | | | | | | Avoids consing up list of strings. * lib.c (vscat): New static function. (scat): New function. (lazy_str): Use scat instead of cat_str. * lib.h (scat): Declared. * eval.c (format_field): Use scat instead of cat_str. * parser.c (open_txr_file, read_eval_stream): Likewise.
* GC-correct order in copy_lazy_str.Kaz Kylheku2016-01-101-2/+2
| | | | | | * lib.c (copy_lazy_str): Eliminate pointless initialization of ls.list and to nil. Make ls.prefix initialization the last step since it's the only operation which conses.
* Don't record form as its own macro origin.Kaz Kylheku2016-01-091-2/+2
| | | | | | | * eval.c (set_origin): Add form != origin to the condition for recording the ancestry. (expand_macro): Use set_origin function instead of direct call to sethash.
* Rework lazy string optimization done in TXR 118.Kaz Kylheku2016-01-091-26/+10
| | | | | | | | | | | | | This is also a bugfix. Padding up the index to be at least 1024 characters longer than the existing prefix was dumb and wrong; it changes the semantics of code which restores the list from the lazy string, like the @(freeform) directive. How much of the string is forced is visible to the caller! * lib.c (lazy_str_force, lazy_str_force_upto): Don't collect pieces from the lazy list and then catenate them in one pass. Instead, use the existing function string_extend, which grows the string exponentially.
* Use struct instead of cons for lazy string fields.Kaz Kylheku2016-01-093-20/+37
| | | | | | | | | | | | | | | | * gc.c (finalize): Must free the dynamic structure attached to the LSTR type now. (mark_obj): Must mark interior of LSTR type's props structure. * lib.c (lazy_sub_str, copy_lazy_str): Copy props structure. (lazy_str): Allocate and initialize props structure. (lazy_str_force, lazy_str_put, lazy_str_force_upto, lazy_str_get_trailing_list, out_lazy_str): Follow representation change. * lib.h (struct lazy_string_props): New struct type. (strut lazy_string): Member opts replaced with props pointer to struct lazy_string_props.
* New internal function for copying malloced object.Kaz Kylheku2016-01-092-0/+9
| | | | | | * lib.c (chk_copy_obj): New function. * lib.h (chk_copy_obj): Declared.
* Squash compiler complaint about _BSD_SOURCE.Kaz Kylheku2016-01-081-1/+1
| | | | | | | | | | | | Some glibc nincompoops have suddenly decided, in their infinite wisdom, that a wise move is to deprecate the _BSD_SOURCE feature selection macro with annoying preprocessor warnings insisting that _DEFAULT_SOURCE be used instead, even though the functions convered by _BSD_SOURCE still exist. * configure: Let's test for _DEFAULT_SOURCE ahead of _BSD_SOURCE.
* Fix Valgrind integration breakage.Kaz Kylheku2016-01-071-1/+1
| | | | | | * signal.c (sig_mask): Pass address of real_oldset to VALGRIND_MAKE_MEM_DEFINED, rather than a copy of the object itself.
* Version 130.txr-130Kaz Kylheku2016-01-056-324/+372
| | | | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise. * txr.vim, tl.vim: Regenerated.
* Bad formatting under data directive.Kaz Kylheku2016-01-051-1/+1
| | | | txr.1: Improperly closed .cblk around example.
* Clarify same-sequence semantics of swap, rotate, shift.Kaz Kylheku2016-01-041-0/+42
| | | | | | * txr.1: Document what happens, or else what isn't specified, if swap, rotate or shift are used on ranges of the same sequence.
* Static slots mustn't trigger instantiation.Kaz Kylheku2016-01-041-2/+3
| | | | | | | | | It is already documented that accessing the instance slots (not static slots) of a lazy struct forces it to instantiate, thus this is a doc conformance bug. * struct.c (lookup_slot): Only call check_init_lazy_structs in the code paths where we calculate the location of an instance slot.
* Revert chr-isdigit/isxdigit, provide new functions.Kaz Kylheku2016-01-044-8/+32
| | | | | | | | | | | | | | | | | | | It was a mistake to change the semantics of the return value of chr-isdigit and chr-isdigit. It breaks code like [partition-by chr-isdigit ...]. The behavior of chr-isdigit and chr-isxdigit is restored to returning t and nil. New chr-digit and chr-xdigit functions are introduced for returning the digit value or nil. * eval.c (eval_init): Register chr-digit and chr-xdigit intrinsics. * lib.c (chr_isdigit, chr_isxdigit): Restore old behavior. (chr_digit, chr_xdigit): New functions. * lib.h (chr_digit, chr_xdigit): Declared. * txr.1: Everything documented.
* defstruct: order function slots before other static slots.Kaz Kylheku2016-01-032-15/+48
| | | | | | | | | | | | | | | | | This allows the initializer expressions for static slots to instantiate objects, and those instances can rely on methods being set up. * share/txr/stdlib/struct.tl (sys:prune-nil-inits): Recognize :function keyword as denoting a static slot. (defstruct): Represent methods and functions as (:function ...) items rather than (:static ...) so they can be distinguished. Function slots appear before other static slots in the static slot list, and their initializing code is placed into the the static-initfun lambda of the sys:make-struct-type call in this order. * txr.1: Documented.
* Better bad slot syntax diagnostic in defstruct.Kaz Kylheku2016-01-031-1/+4
| | | | | | * share/txr/stdlib/struct.tl (defstruct): Issue different error message for a slot specifier which isn't a symbol, and wasn't recognized as a special syntax.
* Bad formatting under destruct.Kaz Kylheku2016-01-021-1/+1
| | | | * txr.1: Missing .desc macro call.
* Bad formatting under RangesKaz Kylheku2016-01-021-0/+3
| | | | * txr.1: Add missing .desc macro invocations.
* Wording change in error_trace.Kaz Kylheku2016-01-021-2/+2
| | | | | * eval.c (error_trace): Change "possibly triggered by" to "during evaluation of".
* Use last-form-evaled mechanism for pattern language.Kaz Kylheku2016-01-023-6/+20
| | | | | | | | | | | | | | We need this now, since file system errors aren't handled in the pattern language any more, after the complex_open refactoring. * eval.c (set_last_form_evaled): New function. * eval.h (set_last_form_evaled): Declared. * match.c (do_match_line, match_files): Save, set up and restore last_form_evaled via set_last_form_evaled function.
* Bugfix: premature open of data source.Kaz Kylheku2016-01-011-1/+1
| | | | | | | | | match.c (open_data_source): complex_open was being called before the check against opening the data source because the query starting with a non-matching directive. This is moved down into a more nested scope. This bug was found thanks to complex_open now throwing exceptions.
* Handle nothrow semantics down in complex_open.Kaz Kylheku2016-01-011-37/+12
| | | | | | | | | * match.c (file_err): Static function removed. (complex_open): New argument, nothrow. Catch exceptions derived from error only if nothrow is true. (v_output, open_data_source): Pass nothrow flag down to complex_open. Eliminate unnecessary error checking.
* Hacky struct fpip gone; complex_open returns stream.Kaz Kylheku2016-01-011-74/+26
| | | | | | | | | | | | | | | * match.c (enum fpip_close): Removed. (struct fpip, fpip_t): Removed. (complex_open): Use high level Lisp library function to return appropriate stream type, and return it directly. Exceptions are turned to a nil return to emulate old behavior. (complex_open_failed, complex_snarf, complex_stream): Static functions removed. (v_output, open_data_source): Use new interface of complex_open. complex_open_failed is just a nile check. complex_stream is a noop, and complex_snarf is just lazy_stream_cons.
* Record-delimiting stream adapter.Kaz Kylheku2016-01-015-0/+313
| | | | | | | | | | | | | | | | | | | | | | | | | | * regex.c (read_until_match): New function. (regex_init): Registered read-until-match intrinsic. * regex.h (read_until_match): Declared. * stream.c (struct delegate_base): New struct type. (delegate_base_mark, delegate_put_string, delegate_put_char, delegate_put_byte, delegate_get_char, delegate_get_byte, delegate_unget_char, delegate_unget_byte, delegate_close, delegate_flush, delegate_seek, delegate_truncate, delegate_get_prop, delegate_set_prop, delegate_get_error, delegate_get_error_str, delegate_clear_error, make_delegate_stream): New static functions. (struct record_adapter_base): New struct type. (record_adapter_base_mark, record_adapter_mark_op, record_adapter_get_line): New static functions. (record_adapter_ops): New static structure. (record_adapter): New function. (stream_init): Registered record-adapter intrinsic. * stream.h (record_adapter): Declared. * txr.1: Documented read-until-match and record-adapter.

| | | | | | | | | | * linenoise/linenoise.c (struct lino_state): New member save_hist_idx. (edit): If save_hist_idx is set, jump to that history position and clear it. Handle ENTER in extended (Ctrl-X) mode similarly to regular ENTER, but setting save_hist_idx. * txr.1: Documented.
* linenoise: bugfix: Ctrl-X bails out of hist searchKaz Kylheku2015-12-311-1/+1
| | | | | | | * linenoise/linenoise.c (history_search): Add CTL('X') to set of characters which terminate search and are processed again in the main editing function, so that Ctrl-X commands work in search.

| | | | | | | | | | | | | * lib.c (name_s): Defined here now. (obj_init): name_s initialized here. * lib.h (name_s): Declared. * match.c (name_s): Definition removed.

| | | | | | | | | | | Same issue as with Vim syntax highlighting. * eval.c (mboundp): Externalize static function. * eval.h (mboundp): Declared. * parser.c (find_matching_syms): Expand fboundp check to encompass mboundp and special_operator_p.
* Version 129.txr-129Kaz Kylheku2015-12-296-361/+482
| | | | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise. * txr.vim, tl.vim: Regenerated.
* last_form_evaled must track argument evaluation.Kaz Kylheku2015-12-291-4/+3
| | | | | | | * eval.c (do_eval): Set last_form_evaled to form before evaluating the arguments, so that any errors which are not attributed to their own sub forms (such as unbound symbols) are attributed to this form.
* Propagate macro ancestry info across macrolet.Kaz Kylheku2015-12-291-1/+4
| | | | | | | | | * eval.c (expand_macrolet): Install a macro ancestor for the expansion of the macrolet. If the original form has a macro ancestor, then use that grandparent ancestor. Otherwise use the original form itself. This way intermediate macrolets which are generated by macros are abbreviated out of ancestry traces.
* Detect loop in error_trace.Kaz Kylheku2015-12-291-0/+3
| | | | | | * eval.c (error_trace): If a form has itself as its macro ancestor, bail the loop. (This only happens in deliberately contrived pathological cases, useful for testing).
* Suppress "which is located at nil".Kaz Kylheku2015-12-291-3/+9
| | | | | * eval.c (error_trace): If info is nil, print alternative message about the location being unavailable.
* Don't suppress detailed error trace for eval-error.Kaz Kylheku2015-12-291-2/+2
| | | | | | | | * eval.c (error_trace): The original idea behind the eval_error_s check is that eval errors already carry line number info, so we don't want to print redundant information. However, the scope of the detailed information has greatly increased, so we need to do this check in the loop.
* Don't record nil as the macro ancestor of a form.Kaz Kylheku2015-12-291-1/+2
| | | | | * eval.c (set_origin): Don't store nil value in the origin_hash.
* New variables for floating-point printing control.Kaz Kylheku2015-12-284-19/+92
| | | | | | | | | | | | | | | | | * lib.c (obj_print_impl): Instead of hard-coded "~s", obtain the format string for floats from the *print-flo-format* special variable, whose default value is "~s". * stream.c (print_flo_digits_s, print_flo_format_s): New symbol variables. (formatv): Use *print-flo-digits* value for default precision for ~f and ~e, rather than hard-coded 3. (stream_init): Initialize print_flo_digits_s and print_flo_format_s, and register special variables under those symbols. * stream.h (print_flo_digits_s, print_flo_format_s): Declared. * txr.1: Documented new specials.
* Whitespace in lazy_str_force.Kaz Kylheku2015-12-281-1/+1
| | | | * lib.c (lazy_str_force): Remove trailing whitespace.
