* parser: bug #; and #S don't play.Kaz Kylheku2021-06-091-6/+15
| | | | | | | | | When #; is used to comment out syntax containing #S, an attempt is made to instantiate a structure using nil as the type, and an exception occurs. * parser.y (hash, struct, tree): Check for parser->ignore and produce nil instead of making any of these objects.

(parser_common_init): Initialize read_unknown_structs flag member of the parser structure from the new special variable. (parse_init): Initialize read_unknown_struct_s variable. Register the *read-unknown-structs* dynamic variable. * parser.h (struct parser): New member, read_unknown_structs.

* json: pattern matching test cases and bugfix.Kaz Kylheku2021-06-031-1/+2
| | | | | | | | | | | | | * parser.y (json_val): We must nreverse the json_pairs which were pushed in right to left order. This didn't matter for constructing hashes so it was left out, but under quasiquoting the order matters: it determines the order of evaluation and of pattern matching. * tests/011/patmatch.tl: New quasiquoting pattern matching cases, including JSON. * y.tab.c.shipped: Regenerated.

| | | | | | | | | | | | | | | | | | | | | | | | | | * eval.c (eval_init): get-json intrinsic registered. * parser.c (prime_parser): Handle prime_json. (lisp_parse_impl): Take enum prime_parser argument directly instead of the interactive flag. (lisp_parse, nread, iread): Pass appropriate prime_parser value instead of the original flag. (get_json): New function. Like nread, but passes prime_json. * parser.h (enum prime_parser): New constant, prime_json. (get_json): Declared. * parser.l (prime_scanner): Handle prime_json. * parser.y (SECRET_ESCAPE_J): New terminal symbol.

* json: two parser bugfixes.Kaz Kylheku2021-05-281-1/+2
| | | | | | | | * parser.y (json): Add forgotten call end_of_json in the '^' production. (json_val): Pass zero to vector, not 0 which is nil. * y.tab.c.shipped: Updated.
* json: hash issues with quasiquoting.Kaz Kylheku2021-05-281-21/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two problems. One is that in #J{~foo:"bar"} the foo expression is parsed while the scanner is in Lisp mode and the : token is grabbed by the parser as a lookahead token in the same mode. Thus it comes back as a SYMTOK (the colon symbol). We fix this by recognizing the colon symbol as synonym of the colon character. But only if it is spelled ":" in the syntax: we look at the lexeme. The second problem is that even if we fix the above, ~foo produces a sys:unquote form which is rejected because it is not a string. We fix this in the most straightforward way: by deleting the code which restricts keys to strings, an extension I already thought about making anyway. * parser.y (json_col): New non-terminal. This recognizes either a SYMTOK or a ':' token, with the semantic restriction that the SYMTOK's lexeme must be ":". (json_vals): Use yybadtok instead of generic error. (json_pairs): Do not require keys to be strings. Use json_col instead of ':', and also yybadtok instead of generic error. * y.tab.c.shipped: Updated.
* json: omission in quasiquoted array.Kaz Kylheku2021-05-271-1/+5
| | | | | | | | * parser.y (json_val): Handle json_vals being a list, indicating quasiquoting. We must nreverse it and turn it into a sys:vector-lit form. * y.tab.c.shipped: Updated.
* json: implement distinguished json quasiquote.Kaz Kylheku2021-05-271-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because #J<json> produces the (json ...) form that translates into quote, ^#J<json> yields a quasiquote around a quote. This has some disadvantages, because it requires an explicit eval in some situtions to do what the programmer wants. Here, we introduce an alternative: the syntax #J^<json> will produce a quasiquote instead of a quote. The new translation scheme is #J X -> (json quote <X>) #J^ X -> (json sys:qquote <X>) where <X> denotes the Lisp object translation of JSON syntax X. * parser.c (me_json): The quote symbol is now already in the json form, so all that is left to do here is to take the cdr to pop off the json symbol. * parser.l (JPUNC, NJPUNC): Allow ^ to be a punctuator in JSON mode. * parser.y (json): For regular #J, generate the new (json quote ...) syntax. Implement J# ^ which sets up the nonzero quasi_level around the processing of the JSON syntax, so that everything is in a quasiquote, finally producing the (json sys:qquote ...) syntax. * lex.yy.c.shipped, y.tab.c.shipped: Updated.
* json: support quasiquoting.Kaz Kylheku2021-05-271-10/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * parser.h (end_of_json_unquote): Declared. * parser.l (JPUNC, NJPUNC): Add ~ and * characters to set of JSON punctuators. (grammar): Allow closing brace character in NESTED, SPECIAL and QSPECIAL statues to be a token. This is because it occurs as a lookahead character in this situation #J{"foo":~expr}. The lexer switches from the JSON to the NESTED start state when it scans the ~ token, so that expr is treated as Lisp. But then } is consumed as a lookahead token by the parser in that same mode; when we pop back to JSON mode, the } token has already been scanned in NESTED mode. We add two new rules in JSON mode to the lexer to recognize the ~ unquote and ~* splicing unquote. Both have to push the NESTED start condition. (end_of_json_unquote): New function. * parser.y (JSPLICE): New token. (json_val): Logic for unquoting. The array and hash rules must now be prepared to deal with json_vals and json_pairs now producing a list object instead of a hash or vector. That is the signal that the data contains active quasiquotes and must be translated to the special literal syntax for quasiquoted vectors and hashes. Here we also add the rules for ~ and ~* unquoting syntax, including managing the lexer's transition back to the JSON start condition. (json_vals, json_pairs): We add the logic here to recognize unquotes in quasiquoting state. This is more clever than the way it is done in the Lisp areas of the grammar. If no quasiquotes occur, we construct a vector or hash, respectively, and add to it. If unquotes occur and if we are nested in a quasiquote, we switch the object to a list, and continue it that way. (yybadtoken): Handle JSPLICE. * lex.yy.c.shipped, y.tab.c.shipped, y.tab.h.shipped: Updated.
* json: extension: allow circle notation.Kaz Kylheku2021-05-261-0/+4
| | | | | | | | | | * parser.l (HASH_N_EQUALS, HASH_N_HASH): Recognize these tokens in the JSON start state also. * parser.y (json_val): Add the circular syntax, exactly like it is done for n_expr and i_expr. And it works! * lex.yy.c.shipped, y.tab.c.shipped, y.tab.h.shipped: Updated.
* New #J syntax for JSON objects in TXR Lisp.Kaz Kylheku2021-05-261-3/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (needs buffer literal error message cleanup) * parser.c (json_s): New symbol variable. (is_balanced_line): Follow braces out of initial state. This concession allows the listener to accept input like #J{"a":"b"}. (me_json): New static function (macro expander). The #J X syntax produces a (json Y) form, with the JSON syntax X translated to a Lisp object Y. If that is evaluated, this macro translates it to (quote Y). (parse_init): initialize json_s variable with interned symbol, and register the json macro. * parser.h (json_s): Declared. (end_of_json): Declared. * parser.l (num_esc): Treat u escape sequences in the same way as x. This function can then be used for handling the \u escapes in JSON string literals. (DIG19, JNUM, JPUNC, NJPUNC): New lex named patterns. (JSON, JLIT): New lex start conditions. (grammar): Recognize #J syntax, mapping to HASH_J token, which transitions into JSON start state. In JSON start state, handle all the elements: numbers, keywords, arrays and objects. Transition into JLIT state. In JLIT start state, handle all the elements of JSON string literals, including surrogate pair escapes. JSON literals share the fallback {UANY} fallback patter with other literals. (end_of_jason): New function. * parser.y (HASH_J, JSKW): New token symbols. (json, json_val, json_vals, json_pairs): New nonterminal symbols, and rules. (i_expr, n_expr): Generate json nonterminal, to hook the stuff into the grammar. (yybadtoken): Handle JKSW and HASH_J tokens. * lex.yy.c.shipped, y.tab.c.shipped, y.tab.h.shipped: Updated.
* parser: improve diagnostic for unterminated exprs.Kaz Kylheku2021-05-241-2/+5
| | | | | | | | | | * parser.y (parse): When issuing the diagostic indicating the likely starting line of the unterminated expression, instead of mentioning that line in the diagnostic text, let's just issue the diagnostic against that line. The programmer's text editor can then jump to that line. * y.tab.c.shipped: Updated.
* parser: #; tests and bugfixes.Kaz Kylheku2021-05-061-0/+7
| | | | | | | | | | | | | | | | This is motivated by the recent crash regression in the #; comment out mechanism. The parser doesn't have adequate coverage in the test suite. * tests/012/syntax.tl: New file, for testing syntax. A problem was found #;.expr did not work inside a list, only at top level. It required a space before the dot. * parser.y (listacc): A couple of productions to handle hash-semicolon immediately followed by a dot without any whitespace, and then by an expression. * y.tab.c.shipped: Regenerated.
* parser: fix regression in #; syntax.Kaz Kylheku2021-05-041-1/+4
| | | | | | | | | | | | A crash has showed up when processing commented-out objects. This is due to the most recent gc fix to the parser. * parser.y (set_syntax_tree): Avoid the set macro when tree has the special value nao (not an object). * y.tab.c.shipped: Regenerated. * y.tab.h.shipped: Likewise.
* parser: gc bug.Kaz Kylheku2021-05-011-4/+11
| | | | | | | | | * parser.y (set_syntax_tree): New static function. Uses GC-correct assignment via set macro. (spec): Call set_syntax_tree instead of raw assignments to parser->syntax_tree, which violate GC rules. * y.tab.c.shipped: Regenerated.
* parser: allow funny UTF-8 in regexes and literals.Kaz Kylheku2021-04-081-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main idea in this commit is to change a behavior of the lexer, and take advantage of it in the parser. Currently, the lexer recognizes a {UANYN} pattern in two places. That pattern matches a UTF-8 character. The lexeme is passed to the decoder, which is expected to produce exactly one wide character. If the UTF-8 is bad (for instance, a code in the surrogate pair range U+DCxx) then the decoder will produce multiple characters. In that case, these rules return ERRTOK instead of a LITCHAR or REGCHAR. The idea is: why don't we just return those characters as a TEXT token? Then we can just incorporate that into the literal or regex. * parser.l (grammar): If a UANYN lexeme decodes to multiple characters instead of the expected one, then produce a TEXT token instead of complaining about invalid UTF-8 bytes. * parser.y (regterm): Recognize a TEXT item as a regterm, converting its string value to a compound node in the regex AST, so it will be correctly treated as a fixed pattern. (chrlit): If a hash-backslash is followed by a TEXT token, which can happen now, that is invalid; we diagnose that as invalid UTF-8. (quasi_item): Remove TEXT rule, because the litchars constituent not generates TEXT. (litchars, restlistchar): Recognize TEXT item, similarly to regterm. * tests/012/parse.tl: New file. * tests/012/parse.expected: Likewise.
* parser: fix few memory leaks in error recovery.Kaz Kylheku2021-04-081-0/+4
| | | | | | | | | * parser.y (var, o_var): In a few error productions in which we have a SYMTOK item, we should free the lexeme. This doesn't solve all leaks: any time we have a parser stack containing SYMTOK or TEXT items that belong to rules that have not yet been reduced, and the parse job is aborted due to errors, we leak those.
* parser: fix bad precedence of @ token.Kaz Kylheku2021-01-241-3/+13
| | | | | | | | | | | | | | | | | | | | | | | Whereas @a..@b parses and transforms to (rcons @a @a), @(a)..@(a) goes to @(rcons a @(a)). * parser.l (grammar): Under 248 compatibility or lower, the @ character now produces the OLD_AT token. Otherwise it produces the '@' character, as before. * parser.y (OLD_AT): New token replaces the '@' at the old low precedence position. '@' is now at the highest precedence, together with OLD_DOTDOT. (We don't care about interactions between '@' and OLD_DOTDOT, because OLD_DOTDOT only exists in 185 compatibility, in which '@' is OLD_AT). (meta): The two rules have to be unfortunately duplicated for OLD_AT, since there is no BNF OR operator in Yacc. * txr.1: Compat note added. * lex.yy.c.shipped: Updated. * y.tab.c.shipped, y.tab.h.shipped: Likewise.

* txr: bugfix: repeat not finding Lisp vars in brace.Kaz Kylheku2020-10-011-5/+9
| | | | | | | | | | | | | | | | | | | The following does not work and is fixed here: @(output) @(repeat) @{lisp-expr ...} @(end) When a Lisp expression occurs in a braced expansion syntax, it is not not traversed to find variables. * parser.y (extract_vars): Treat the second element of a sys:var as a Lisp expression, and find variables.

* txr: identify output repeat vars at parse timeKaz Kylheku2020-08-171-1/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | Up to now the @(repeat) and @(rep) directives have scanned their interior to find output variables. We now hoist that into the parser; the variables are found up-front and integrated into the abstract syntax. This work anticipates doing a more proper job of identifying free variables in Lisp expressions. * match.c (extract_vars): Delete static this function here. It moves into parser.y. (extract_bindings): Don't call extract_vars to obtain the variables occurring in the repeat body. Get it as a new argument, occur_vars. (do_output_line, do_repeat): Extract the new occur_vars element of the abstract syntax node and pass it to extract_bindings. * parser.y (extract_vars): New static function, moved here from match.c.

* parser: eliminate struct list_accum.Kaz Kylheku2020-04-101-42/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | As a final round of this recent work, we observe that since the accumulator structure has been reduced to two members, we can eliminate one of them by using a cons cell as the accumulator, and threading the second value through the cdr. That is to say, the listacc grammar rule's semantic value will now be the tail cons of the list being constructed. The cdr of this cons will, temporarily, be a back pointer to the head (making the list temporarily circular). The n_exprs reduction will fix this up; it will put the correct terminating atom in place of the head (either nil, or the dotted item if there is one), and yield the head as the semantic value. * lib.h (struct list_accum): Removed. (Thus, finding a better home for this would, after all, have been a waste of time). * parser.y (lacc, splacc): Static functions removed. (union YYSTYPE): lacc membber removed. (n_exprs): Adjust to new semantic value coming from listacc. (listacc): Now of type val again. Yields pointer to tail cons as semantic value, whose cdr points to the head of the list.
* parser: move cons dot handling to higher rule.Kaz Kylheku2020-04-101-18/+3
| | | | | | | | | | | | | | * lib.h (struct list_accum): dot member removed. * parser.y (misplaced_consing_dot_check): Function removed. The misplaced consing dot diagnostic is still provided as before by yybadtoken. (n_exprs): Production for CONSDOT is moved here out of listacc. There is no $1.dot member to deal with; the dot is very simply handled here. (listacc): Remove calls to misplaced_consing_dot_check. CONSDOT production moved to n_exprs. (lacc, splacc): Remove initialization of dot member.
* parser: streamline core list building.Kaz Kylheku2020-04-091-47/+57
| | | | | | | | | | | | | | | | | | | | | The r_expr grammar symbol is replaced with listacc which has a different type: a new Yacc node type that has three fields for building a list from left to right without nreverse, and the dotted pair item. * lib.h (struct list_accum): New struct type. Not a great place for it, but we don't have a parser-specific header that is included before y.tab.h: parser.h is included after y.tab.h. * parser.y (misplaced_consing_dot_check): The val argument is just the existing dotted item; if it is other than nao, the error is generated. (lacc, splacc): New static functions. (YYSTYPE): New union member, lacc of type struct list_accum. (r_exprs): Grammar symbol removed. (listacc): New grammar symbol of type listacc. The rules are those of r_exprs upgraded to construct the list in one pass.

The scapegoat algorithm is used, which requires no additional storage in a cell. In the future we may go to something else, like red-black trees, and carve out a bit in the tag field of the cell for the red/black color. Tree cells store only single key objects, not key/value pairs. However, which part of the key object is compared is determined by a custom key function stored in the tree container. For instance, tree nodes can be cons cells, and car can be used as the key function; the cdr then stores an associated value. Trees have a printed notation #T(<props> <key>*) where <props> is a list of up to three items: <props> ::= ([<key-fn> [<less-fn> [<equal-fn>]]]) key-fn, less-fn and equal-fn are function names. If they are missing or nil, they default, respectively, to identity, less and equal. For security, the printed notation is machine-readable only if these options are symbols, not lambda expressions. Furthermore, the symbols must be listed in the special variable *tree-fun-whitelist*. * eval.c (less_s): New symbol variable.

* New data type: tnode.Kaz Kylheku2019-09-221-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Binary search tree nodes are being added as a basic heap data type. The C type tag is TNOD, and the Lisp type is tnode. Binary search tree nodes have three elements: a key, a left child and a right child. The printed notation is #N(key left right). Quasiquoting is supported: ^#N(,foo ,bar) but not splicing. Because tnodes have three elements, they they fit into TXR's four-word heap cell, not requiring any additional memory allocation. These nodes are going to be the basis for a binary search tree container, which will use the scapegoat tree algorithm for maintaining balance. * tree.c, tree.h: New files. * Makefile (OBJS): Adding tree.o. * eval.c (expand_qquote_rec): Recurse through tnode cells, so unquotes work inside #N syntax. * gc.c (finalize): Add TNOD to no-op case in switch; tnodes don't require finalization. (mark_obj): Traverse tnode cell. * hash.c (equal_hash): Add TNOD case. * lib.c (tnode_s): New symbol variable. (seq_kind_tab): New entry for TNOD, mapping to SEQ_NOTSEQ. (code2type, equal): Handle TNOD. (obj_init): Initialize tnode_s variable. (obj_print_impl, populate_obj_hash): Handle TNOD. (init): Call tree_init function in tree.c. * lib.h (enum type, type_t): New enumeration TNOD. (struct tnod): New struct type. (union obj, obj_t): New union member tn of type struct tnod. (tnode_s): Declard. * parserc.c (circ_backpatch): Handle TNOD, so circular notation works through tnode cells. * parser.l (grammar): Recognize #N prefix, mapping to HASH_N token. * parser.y (HASH_N): New grammar terminal symbol. (tnode): New nonterminal symbol. (i_expr, n_expr): Add tnode cases to productions. (yybadtoken): Map HASH_N to "#N" string.
* parser: #; notation shouldn't intern symbols.Kaz Kylheku2019-08-181-2/+3
| | | | | | | | | | When #; is used to ignore an object, parsing that object shouldn't cause symbols to be interned, nor errors about unknown packages. * parser.y (ifnign): New macro. (i_expr, n_expr): For SYMTOK, don't call symhlpr when parsing under ignore flag. Just yield nil as the semantic value.
* parser: rename circ_suppress flag.Kaz Kylheku2019-08-181-13/+13
| | | | | | | | | | | * parser.h (struct parser): eof flag changed to unsigned char. circ_suppress flag renamed to ignore, changed to unsigned char and relocated next to eof to compact together. * parser.c (parser_circ_ref): Follow rename. * parser.y (hash_semi_or_n_expr, hash_semi_or_i_expr, n_exprs, parse): Likewise.
* parser: give start of a bad forms even if line 1.Kaz Kylheku2019-07-261-1/+4
| | | | | | | * parser.y (parse): Emit the "while parsing form starting at line N" even if N is 1. I think the idea here was supposed to be to suppress this additional message for parses that don't advance from the starting line, so I'm fixing it that way.
* txr: regression: lack of file name in error messages.Kaz Kylheku2019-07-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was broken on April 21, 2019 in commit 2e36e0feae8d1dd75c8410b365d7dc33b30ce66b (April 21, 2019) which changed parse_once in such a way that the name being passed down was no longer stored in the parser. The ensure_parser function being relied upon doesn't take on the responsibility of propagating the name from the stream to the parser, so the parser ends up with a nil name. Let's just smooth this over by having ensure_parser take a name parameter. If ensure_parser creates a new parser, it puts in the name. If the name is nil, then it is taken from the stream. * eval.c (load): Pass name to ensure_parser. * match.c (v_load): Likewise. * parser.c (parser): Take name parameter, and plant into newly constructed parser. (ensure_parser): Take name parameter. When creating a parser, give it that name, or if name is specified as nil, then give it the name taken from the stream. (parser_set_lineno): Pass nil name to ensure_parser. (lisp_parse_impl, read_file_common): Pass name to ensure_parser. * parser.h (parser, ensure_parser): Declarations updated. * parser.y (parse_once): Pass name to ensure_parser. * txr.c (txr_main): Pass spec_file_str to ensure_parser.
* @(define): bugfix: incorrect parameter list walk.Kaz Kylheku2019-07-021-2/+2
| | | | | | | | | * parser.y (elem, define_clause): The match_reg_params function is supposed to walk the pattern function parameters, not the argument of the define directive (of which the second one is those arguments). This bug causes spurious unbound variable warnings when function bodies refer to their second or subsequent arguments. Issue reported by user vapnik spaknik.
* C99: get rid of useless inline instantiations.Kaz Kylheku2019-05-021-5/+0
| | | | | | | | | | | * hash.c, lib.c, parser.y, unwind.c: Remove useless declarations that were believed to be C99 inline instantiations. This was mistakenly added at the time the Solaris issue was discovered that _XOPEN_SOURCE values of 600 or greater require compiling in C99 mode. We use "static inline" under C99 for inline functions; instantiation is not applicable at all to inline functions that don't have external linkage.
* parser: always use stream-associated parser for parse_once.Kaz Kylheku2019-04-211-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This refactoring is needed for fixing the off-by-one line number bug when the hash bang line is processed. * eval.c (load): Don't define parser locally; ensure there is one in the stream and use it. * match.c (v_load): Likewise. * parser.c (get_parser_impl): Renamed to parser_get_impl and changed from internal to external linkage. (ensure_parser): Changed to external linkage. (lisp_parser_impl, read_file_common): Follow rename of get_parser_impl. * parser.h (parse_once): Declaration updated. (parser_get_impl, ensure_parser): Declared. * parser.y (parse_once): Take self parameter; drop parser parameter. Ensure a parser to the stream, rather than declaring one locally. Don't clean up the parser when done, just let the stream clean it up. * txr.c (parse_once_noerr): Parser argument is dropped and not passed to parse_once. Program name is passed as self argument to parse_once. (txr_main): When parsing the TXR pattern query, don't define a parser locally; ensure there is one in the stream and use it, like in load and v_load.

(generic_funcall): Now a wrapper for do_generic_funcall which registers fcall frames if backtrace support is enabled. (funcall, funcall1, funcall2, funcall3, funcall4): Route to slow generic_funcall path if backtraces are enabled. * lisplib.c (debugger_instantiate, debugger_set_entries): New static functions. (lisplib_init): Autload support for debug module via above new functions. (lisplib_try_load): Save and restore debugger state in new way using debug_set and debug_restore, with specific mask values. * parser.y (parse_once): Disable debugging in new way. * share/txr/stdlib/debug.tl New file. * sighal.h (EJ_DBG_MEMB, EJ_DBG_SAVE, EJ_DBG_REST): New macros for saving/restoring debug state. (EJ_OPT_MEMB, EJ_OPT_SAVE, EJ_OPT_REST): Reference the above macros to include debug state in extended jump context. * txr.c (help): Document --backtrace and that that -d implies --backtrace.

(step_mode, next_depth, breakpoints, last_command, cols): Static variables removed. (debug_check): C99 inline instantiation removed. (help, show_bindings): Static functions removed. (debug): Function removed. (debug_set_state): Now takes one int argument, returns int. It's anticipated that the new debug system will have a simple on-off switch; there won't be a debug_depth hack. (debug_restore_state): Function removed. (debug_init): Emptied. * debug.h (debug_depth, debug_state_t): Declarations removed. (debug_enter, debug_leave, debug_return): Macros removed. (debug_check): Inline function removed. (debug_set_state): Declaration updated. (debug_restore_state): Declaration removed. (debug_frame, debug_end): Macros removed. * eval.c (do_eval, me_interp_macro): Debugging support scrubbed. * lisplib.c (lisplib_try_load): Adapt to debug_set_state interface change. * match.c (h_fun, do_match_line, v_fun, match_files, match_fun): Debugging support scrubbed. * parser.y (parse_once): Adapt to debug_set_state interface change. * protsym.c: Regenerated. * signal.h (debug_depth): Declaration removed. (EJ_DBG_MEMB, EJ_DBG_SAVE, EJ_DBG_REST): Macros removed. (EJ_OPT_MEMB, EJ_OPT_SAVE, EJ_OPT_REST): Reduced to unconditionally empty definitions for future use. * unwind.c (uw_push_debug): Function removed. * unwind.h (uw_frtype_t): UW_DBG enum member removed. (struct uw_debug): struct declaration removed. (union uw_frame): db member removed. (uw_push_debug): Declaration removed. * txr.1: Debugger doc removed.
* gethash_c: review uses and improve or replace.Kaz Kylheku2019-02-141-2/+1
| | | | | | | | | | | | | | | | | | | | * eval.c (env_fbind, env_vbind, reg_symacro): Use gethash_l instead of gethash_c to eliminate repeated cdr operations on the same cell. * hash.c (sethash): Since new_p is never used, eliminated it and use nulloc. (group_reduce): Use gethash_l instead of gethash_c. * lib.c (obj_init): Replace rplacd(gethash_c(...)) pattern whose return value is not used with with sethash. We lose some diagnosability here since sethash doesn't take a "self" argument. (obj_print_impl, obj_hash_merge): Use gethash_l instead of gethash_c. * parser.y (ensure_parser, parser_circ_def, get_visible_syms, rlset): Use gethash_l instead of gethash_c.
