| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * arith.c (arith-init): Changing *flo-...* from special to lexical, and adding un-earmuffed variants. The earmuffed versions are obsolescent. Adding %pi% and %e% global lexicals. Earmuffed versions are also made global lexical, and obsolescent. * eval.c (lookup_global_var, lookup_global_var_l): New functions. (lookup_var): Uses lookup_global_var. (reg_varl): New function. (reg_var): Uses reg_var. (eval_init): Register global lexicals user-package, system-package and keyword-package. Old symbols with earmuffs are obsoleted, and also turned into global lexicals. (top-vb, top-fb): Changed to lexical. * eval.h (lookup_global_var, lookup_global_var_l, reg_varl): Declared. * genvim.txr: Scan ver.tl so that the lib-version variable is included. Extract reg_varl calls. * glob.c (glob_init): glob-err and other variables made lexical. * lib.c (get_user_package, get_system_package, get_keyword_package): Use lookup_global_var_l to avoid searching dynamic scope for lexicals which cannot be dynamically rebound. * share/txr/stdlib/ver.tl (lib-version): New global lexical variable.

| | | | | | | | | | | | | | | | | | | | | * eval.c (defvarl_s, defparm_s, defparml_s, sys_mark_special_s): New symbol variables. (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.

| | | | | | | | | | | | | | * lisplib.c (place_set_entries): Add placelet to list of names. * share/txr/stdlib/place.tl (sys:placelet1, placelet): New macros. (defplace dwim): Do not retrieve the place's value into a local variable and have the getter expand to that variable. Rather, have the getter retrieve the value. A getter that refers to a cached copy breaks the semantics of placelet, and any place operator which can evaluate the location after it is stored. * txr.1: Documented placelet.

* Support trailing semicolon after hex/octal characters.Kaz Kylheku2015-07-021-1/+16
| | | | | | | | | | | | | | | | * parser.l (%option): Remove nounput option since we need yyunput. (grammar): Rule for matching hex and octal escape in SPECIAL state recognizes optional semicolon. In 109 compatibility, this is pushed back into the stream, otherwise consumed. * txr.1: Updated documentation, including compat notes. * genvim.txr (txr_char): Include optional semicolon in match. Corrected some errors where 8 and 9 were being included as matches for octal digits. (txr_error): Default match for \x or \o not followed by digits.
