* Version 71txr-71Kaz Kylheku2013-12-071-2/+2
| | | | | | | | | | * txr.c (version): Bumped. * txr.1: Bumped version and set date. * configure (txr_ver): Bumped. * RELNOTES: Updated.
* * eval.c (eval_init): Update registration of regex-compileKaz Kylheku2013-12-061-5/+8
| | | | | | | | | | | | | | | | | | | to reflect that it has two arguments now. * parser.y (grammar): Update calls to regex_compile to pass two arguments. Since we don't expect regex_compile to parse, we specify the error stream as nil. (spec): The "secret syntax" for a regex is simplified not to include the slashes. This provides better diagnostics for unterminated syntax and requires less string processing to generate. Also, the form returned doesn't have the regex symbol consed onto it, which parse_regex just throws away. * regex.c (regex_compile): Now takes a stream argument. * regex.h (regex_compile): Declaration updated. * txr.1: Updated
* * regex.c (regex_compile): Handle string input.Kaz Kylheku2013-12-051-4/+11
| | | | | | | * regex.h (regex_compile): Don't call argument regex_sexp, since it can be a string. * txr.1: Updated.
* * eval.c (eval_init): Registered regex_parse as newKaz Kylheku2013-12-051-1/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | intrinsic function and std_null as new variable. * parser.h (yylex_destroy): Existing function declared. * parser.l (regex_parse): New function. New lexical syntax added which returns SECRET_ESCAPE_R. * parser.y (SECRET_ESCAPE_R): New token. (spec): Added syntactic variant which lets us smuggle a regex into the parser easily. * stream.c:x (std_null): New global variable. (null_stream_print): New static function. (null_ops): New static structure. (make_null_stream): New function. (stream_init): Protect and initialize std_null. * stream.h (std_null, make_null_stream): Declared. * txr.1: New features documented: regex-parse, *stdnull*. * txr.c (txr_main): Call yylex_destroy after parsing the program now that I know about this function; this can free up some memory.
* * eval.c (eval_init): New functions countqual, countql, countqKaz Kylheku2013-11-291-0/+33

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.

* * match.c (require_s): New variable.Kaz Kylheku2013-06-111-3/+24
| | | | | | | | | | | | | | (v_require): New static function. (syms_init): Initialize require_s.

* * 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.
