* * stream.c (indent_mode_put_string): Function removed,Kaz Kylheku2015-08-041-0/+8
| | | | | | | logic hoisted into put_string. (put_string, put_char): Always count column, indent mode or not. * tests/009/json.expected: Updated.
* Define TXR_DBG macro when compiling debug build.Kaz Kylheku2015-08-031-0/+11
| | | | | | | | | * Makefile (dbg/%.o): Pass $(DBG_ONLY_FLAGS) to COMPILE_C_WITH_DEPS recipe macro. * configure (debug_only_flags): New macro. (gen_config_make): Generate DBG_ONLY_FLAGS. Add debug-only-flags to usage help text.
* Custom linker flags support.Christopher Meng2015-08-031-0/+14
| | | | | | | | | | | | * Makefile (PLATFORM_FLAGS): Rename to PLATFORM_CFLAGS. (LDFLAGS): New variable. Includes -lm and PLATFORM_CFLAGS.

* Switching some globals to lexical and changing some names.Kaz Kylheku2015-08-031-0/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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. (*lib-version*): Turned lexical. Obsolescent. * signal.c (sig-init): sig-* variables turned lexical. * sysif.c (sysif-init): s-*, poll-* and w-* variables turned lexical. * syslog.c (syslog-init): log-* variables turned lexical. * txr.c (sysroot-init): stdlib and *txr-version* variables turned lexical. txr-version variable added, and *txr-version* is obsolescent. (txr-main): self-path variable added. *self-path* turns lexical and is obsolescent. * txr.1: Documentation updated. Lexical variables not referred to as special. Special variables referred to as special.
* * txr.c (txr_main): Bugfix: register *args-full*, the variableKaz Kylheku2015-08-031-0/+6
| | | | | described in the documentation! We keep *full-args* for backward compatibility, as an obsolescent feature.
* Introducing global lexicals: defvarl, defparml.Kaz Kylheku2015-08-031-0/+23
| | | | | | | | | | | | | | | | | | | | | * 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. Register defparm to me_def_variable, and register defvar and defparml to the same. * txr.1: Document support for global lexical scopes and the new macros.
* Support lstat and fstat.Kaz Kylheku2015-08-021-0/+17
| | | | | | | | | | | | | | | * stream.h (statf): Declaration removed. * sysif.c (w_stat): Function takes val instead of const wchar_t * as leftmost argument. (w_lstat, w_fstat): New static functions, with same interface as w_stat. (stat_to_list, stat_impl): New static functions. (statp, statl): New static functions. (statf): Function removed, name re-used for new static function. (sysif_init): stat intrinsic registered to statp function, not statf. lstat and fstat intrinsics registered to statl and statf. * txr.1: Documented lstat and fstat.
* Pass pretty flag to cobj print operation.Kaz Kylheku2015-08-011-0/+23
| | | | | | | | | | | | | | | | | | | | | * hash.c (hash_print_op): Take third argument, and call cobj_print_impl rather than cobj_print. * lib.c (cobj_print_op): Take third argument. The object class is * printed with obj_print_impl. (obj_print_impl): Static function becomes extern. Passes its pretty flag argument to cobj print virtual function. * lib.h (cobj_ops): print takes third argument. (cobj_print_op): Declaration updated. (obj_print_impl): Declared. * regex.c (regex_print): Takes third argument, and ignores it. * stream.c (stream_print_op, stdio_stream_print, cat_stream_print): Take third argument, and ignore it. * stream.h (stream_print_op): Declaration updated.
* * eval.c (special_p): Function renamed to special_var_p.Kaz Kylheku2015-08-011-0/+9
| | | | | | | | (expand_opt_params_rec, expand_vars): Follow rename of special_p. (eval_init): Register special-operator-p and special-var-p intrinsics. * txr.1: Document special-operator-p and special-var-p.
* Big TXR Lisp documentation rearrangement.Kaz Kylheku2015-08-011-0/+7
| | | | | * txr.1: Numerous sections moved around. Miscellaneous formatting and wording fixes. New sections under TXR Lisp intro section.
* string_output renamed to string_outKaz Kylheku2015-07-311-0/+9
| | | | | | | * stream.c (struct string_output): Renamed to string_out. (string_out_stream_destroy, string_out_byte_callback, string_out_put_char, strnig_out_put_string, string_out_put_byte, make_string_output_stream, get_string_from_stream): Follow rename.
* Simplify type check code in stream module.Kaz Kylheku2015-07-311-0/+17
| | | | | | | | | | | | | | | * stream.c (get_string_from_stream, get_list_from_stream, stream_set_prop, stream_get_prop, close_stream, get_line, get_char, get_byte, unget_char, unget_byte, put_string, put_char, put_byte, flush_stream, seek_stream): Use cobj_handle and cobj_ops instead of type_check and type_assert. (get_indent_mode, test_set_indent_mode, set_indent_mode, get_indent, set_indent, inc_indent, width_check): Use cobj_handle and cobj_ops instead of stream->co.handle and stream->co.ops for safety. (vformat, format): Use class_check instead of type_check and type_assert.
* Multi-line, indented printing of structure.Kaz Kylheku2015-07-311-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * eval.c (op_error): New static function. (macro_form_p, fboundp): Static to external. (special_operator_p): New function. (eval_init): Register macrolet and symacrolet to op_error. These are recognized and processed by expand, but we want them in the op table so they are reported by special_operator_p. * eval.h (fboundp, macro_form_p, special_operator_p): Declared. * hash.c (print_key_val): Break long lines on spaces between pairs with stream_width_check. (hash_print_op): Implement split and indented printing. * lib.c (obj_print_impl): New static function, resulting from a merge of obj_print and obj_pprint. Fixes some wrong-way recursion bugs: obj_pprint recursed into obj_print in some places. Adds support for multi-line printing of vectors and lists, with indentation using the new interfaces in streams. * stream.c (strm_base_init): Update initializer. (put_indent, indent_mode_put_string): New static functions. (put_string): Use indent_mode_put_string in either of the two indent modes. (put_char): Implement indent mode.

* Correction to COBJ initialization pattern.Kaz Kylheku2015-07-301-0/+15
| | | | | | | | | | | | | In fact, the previosuly documented process is not correct and still leaves a corruption problem under generational GC (which has been the default for some time). * HACKING: Document flaw in the initialization pattern previously thought to be correct, and show fix. * hash.c (copy_hash): Fix instance of incorrect pattern. * regex.c (regex_compile): Likewise.

* Set up blank top_srcdir if building in source directory.Kaz Kylheku2015-07-231-0/+20
| | | | | | | | | | | | | | | | | | This means short, relative names are used for C source files when compiling in the source directory. * Makefile (CFLAGS): Exclude -iquote $(top_srcdir) arguments if top_srcdir is blank. Remove slash after $(top_srcdir), since the variable includes it now, if its value is not blank. (SRCS, ABBREV, opt/%-win.o, lex.yy.c, y.tab.c, install): Remove slash after $(top_srcdir). (dbg/%.o, opt/%.o): Only include rules for depending on $(top_srcdir)%.c prerequisite if top_srcdir is not blank.

(dbg/%.o, opt/%.o): Extra set of pattern rules for searching for prerequisites in $(top_srcdir) where primary C sources are found and in the local dir where some generated C is found. This way we don't rely on VPATH. (opt/%.res): Bogus target removed. (VPATH): Removed in favor of explicitly referencing $(top_srcdir). Was causing problems for tests. (lex.yy.c, y.tab.c): Prerequisites referenced in $(top_srcdir).
* * parser.l (grammar): Do not allow unescaped newline inKaz Kylheku2015-07-231-0/+12
| | | | | | | | | | | word list literals and word list quasiliterals, except in <= 109 compatibility mode. An escaped newline in these literals, together with surrounding whitespace, now produces a single space, except in <= 109 compatibility mode. * txr.1: Documented new rules for WLL's and QLL's, and added compatibility notes.
* * genvim.txr: Scan cadr.c, cadr.tl, with-resources.tl, txr-case.tl.Kaz Kylheku2015-07-231-0/+6
