* Different banner text for plain mode.Kaz Kylheku2020-07-241-2/+6
| | | | | | * txr.c (banner): In plain mode, indicate that the mode is in effect. Do not suggest any Ctrl-X commands, since they are not recognized.
* More reasonable fallback for self path: revisited.Kaz Kylheku2020-07-141-0/+5
| | | | | | | | | | | | | | | | This partially reverts and reworks commit c5afb01548c5b6bf4ec83373b5e2e09f14690b01 from May 4, 2018. I have no idea why I replaced fallback code which does something quite reasonable: invokes realpath on the value from argv[0]. The commit comment claims that this breaks when the program is not invoked with an absolute path, but how can that be, if realpath is used? * txr.c (get_self_path): Let's keep TXR_INST_PATH, and return that in the case that progname_u8 is null, because of a null argv[0]. Otherwise, let's revert to the original strategy of calling realpath on progname_u8.
* c_num: now takes self argument.Kaz Kylheku2020-06-291-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The c_num and c_unum functions now take a self argument for identifying the calling function. This requires changes in a large number of places. In a few places, additional functions acquire a self argument. The ffi module has the most extensive example of this. Some functions mention their name in a larger string, or have scattered literals giving their name; with the introduction of the self local variable, these are replaced by references to self. In the following changelog, the notation TS stands for "take self argument", meaning that the functions acquires a new "val self" argument. The notation DS means "define self": the functions in question defines a self variable, which they pass down. The notation PS means that the functions pass down an existing self variable to functions that now require it. * args.h (args_count): TS. * arith.c (c_unum, c_num): TS.

* lib: streamline interning slightly.Kaz Kylheku2019-08-201-1/+1
| | | | | | | | | | | | | | | | | | | | | We get rid of some defaulting and error checks from interning. This saves a few cycles on startup in the large number of intern calls that are performed. * eval.c (eval_init): Wire the intern intrinsic to the new intern_intrinsic function rather than intern. * lib.c (intern): Remove package lookup and error check on str argument. (intern_intrinsic): New function, which has the package lookup and error check. (intern_fallback): Remove package lookup and error check. * lib.h (intern_intrinsic): Declared. * txr.c (txr_main): Fix one instance of an intern call that relies on defaulting of the second argument, by passing cur_package.
* 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.
* bugfix: source lineno off by one under hash bang.Kaz Kylheku2019-04-211-3/+8
| | | | | | | | | | | | | | * eval.c (load): When we read and discard a hash bang line, we must set the parser line number to two. * parser.c (parser_set_lineno): New function. * parser.h (parser_set_lineno): Declared. * txr.c (check_hash_bang): New argument, occurs. (txr_main): Track whether hash bang has occurred in a new local variable hb_occurs. Then, before parsing, if hash bang has occurred, set the line number to two.
* parser: always use stream-associated parser for parse_once.Kaz Kylheku2019-04-211-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Register dbg-clear, dbg-set, dbg-restore intrinsics. Register dbg-enable, dbg-step, dbg-backtrace and dbg-all bitmask variables, Lisp equivalents of DBG_ENABLE, DBG_SETP, DBG_BACKTRACE and DBG_ALL.

(unwind_to_exit_point): Save pointer to original frame stack and restore it when calling error_trace. This is so that error_trace can walk the stack to collect a backtrace. (uw_find_frames_by_mask, uw_push_fcall): New functions. (uw_late_init): Initialize args_s and fcall_frame_type. gc-protect fcall_frame_type.

| | | | | | | | | | | | | | | | | | | Errors encountered when parsing or evaluating a source file should be handled using a handler rather than a catch, so that the unwind stack is available to the error reporting function. This anticipates being able to dump a backtrace. * txr.c (parse_once_noerr, read_eval_stream_noerr): Adjust to reduced argument count in ignerr_func_body macro. * unwind.c (uw_trace_error): New function. * unwind.h (uw_trace_error): Declared. (ignerr_func_body): Revised to establish a handler in addition to the catch. The catch now doesn't do anything other than provide an intercepting exit point; the error_trace call is moved into the handler, and so it executes in a context where unwinding hasn't happened yet.
* repl: groundwork for recursive listener invocation.Kaz Kylheku2019-04-081-1/+1
| | | | | | | | | | | | | | | | | * parser.c (lino_ctx, repl_level): New static variable. (repl): Increment repl_level on entry and decrement on exit. On the initial entry, allocate the lino_t object, storing it in the new static variable. Free it on outermost exit. The number of > characters in the prompt indicates the nesting level. The function now takes an environment parameter, which is applied to the evaluation of the input form. The intent is to be able to supply symbol macros which expand to function calls implementing debugger commands. (parser_init): Register sys:repl intrinsic. * parser.h (repl): Declaration updated. * txr.c (txr_main): Pass nil environment parameter to repl
* sysrooting: trailing slash needed on directory.Kaz Kylheku2019-02-161-0/+4
| | | | | | | | | * txr.c (sysroot_init): prog_dir is missing a trailing slash, and this breaks the fallback case when we're running a renamed txr executable in the build directory. The presence of the trailing slash had also been documented for the txr-path variable, which is now obsolescent and undocumented. That is hereby fixed.
* txr-exe-path: New variable.Kaz Kylheku2019-02-151-0/+1
| | | | | | | | | * txr.c (sysroot_init): Make prog_path available via the txr-exe-path variable. The txr-path variable becomes obsolescent. * txr.1: Documented txr-exe-path; removed documentation for txr-path.
* command line: support -f in Hash Bang Null Hack.Kaz Kylheku2019-01-281-3/+5
| | | | | | | | | | | | * txr.c (txr_main): In processing the -f option, if there is already an input source, but its name exactly matches the argument of the -f option, then ignore the -f and its option intead of terminating with a diagnostic. This allows the user to use -f in the Null Hack to achieve the usual trick of allowing the script to take options passed through to the interpreter. * txr.1: Documented.
* command line: improve -c option diagnostic.Kaz Kylheku2019-01-281-2/+2
| | | | | | | * txr.c (txr_main): Fix misleading message formatting here. The spec_file string is irrelevant; we must show the argument to -c which is in arg. The name of the input source is spec_file_str; let's show that.
* command line: better diagnosis for --args and --eargsKaz Kylheku2019-01-281-3/+15
| | | | | | | | | * txr.c (txr_main): Diagnose accurately when --args or --eargs is specified without any of the required trailing syntax, instead of complaining about --args or --eargs being an unknown option. Also, fix the error message about --eargs not having an argument, such that it doesn't insinuate that there exists an --eargs=value syntax.

* bugfix: error on empty script file.Kaz Kylheku2018-11-051-8/+12
| | | | | * txr.c (check_hash_bang): When the file is empty, get_line returns nil.
* Hide deprecated, undocumented variables.Kaz Kylheku2018-10-301-1/+2
| | | | | | | | | | * arith.c (arith_init): Do not define *flo-dig*, *flo-max*, *flo-min*, *flo-epsilon*, *pi* and *e* unless compatibility with TXR 199 or earlier is requested. * txr.c (txr_main): Likewise for *self-path*. * txr.1: Compat note added.
* initialization: use self_path_s instead of re-interning.Kaz Kylheku2018-10-301-1/+1
| | | | | | * txr.c (txr_main): When establishing self-path with a new value, use self_path_s instead of calling intern on the symbol name again.
* Replace informality in command line help.Kaz Kylheku2018-05-241-1/+1
| | | | | | | * txr.1 (help): Someone reading the help text doesn't necessarily know that --help produced it; it can be read by someone in contexts where that same person didn't just obtain it by running txr --help.
* More reasonable fallback for self path.Kaz Kylheku2018-05-041-9/+1
| | | | | | | | | | | | | | | | * Makefile (opt/txr.o, dbg/txr.o): Set up TXR_REL_PATH preprocessor symbol on command line which specifies the hard installation path derived from the configure prefix. * txr.c (get_self_path): The fallback implementation simply returns TXR_REL_PATH. This will work if in fact the executable is installed at that path. What it means is that the build of TXR which uses this fallback get_self_path will not support relocation: the installation cannot be moved to another directory, yet still find its supporting files. This is better than what we are replacing: not working even in the original installation directory, if not invoked by an absolute path.
* bugfix: correcly obtain self path on Solaris.Kaz Kylheku2018-05-041-0/+8
| | | | | | | | | | | | * configure: Add detection for getexecname. * sysif.c (getcwd_wrap): Change static function to external. * sysif.h (getcwd_wrap): Declared. * txr.c (get_self_path): New implementation for Solaris using getexecname, which requires us to prepend the current directory name if the result is a relative path.
* Mac-OS: replace nonworking method of getting self-path.Kaz Kylheku2018-05-041-0/+13
| | | | | | | | | TXR's fall-back method of getting the executable's own path is broken in the Mac-OS port, which means that TXR doesn't work when invoked via PATH search. Mac-OS-specific code is required. * txr.c (get_self_path): New variant for Darwin, using the platform-specific function _NSGetExecutablePath.
* Application code is now in a package called pub.Kaz Kylheku2018-04-091-1/+2

* Implement compiled file loading.Kaz Kylheku2018-04-041-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | * eval.c (load): If open_txr_file indicates compiled file by setting txr_lisp_p to character #\o, use read_compiled_file. * match.c (v_load): Likewise. * parser.c (open_txr_file): Recognize the .tlo suffix, and also try to open a .tlo version of an unsuffixed file before trying it as .tl. Indicate a .tlo file by setting txr_lisp_p to the character #\o rather than t. (read_file_common): New static function, made from contents of read_eval_stream. Will either evaluate forms or load compiled code by instantiating virtual machine descriptions and performing their top-level execution. (read_eval_stream): Now a wrapper for read_file_common. (read_compiled_file): New function. * parser.h (read_compiled_file): Declared. * txr.c (help): List new --compiled option. (txr_main): If --compiled is specified, set txr_lisp_p to #\o to load as compiled code. Update error message that -c is not compatible with --lisp or --compiled. If txr_lisp_p is #\o, then use read_compiled_file.
* Eliminate always false expression.Kaz Kylheku2018-02-161-1/+1
| | | | | | * txr.c (txr_main): Since parser.errors being nonzero is handled earlier, it must be zero at the final return point and need not be tested.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hash bang mechanism is handled in one place, and disentangled from all parsing logic. It is also endowed with special powers. * eval.c (load): Pass one less argument to read_eval_stream. * match.c (v_load): Likewise. * parser.c (read_eval_stream): hash_bang_support Boolean argument removed. Hash bang logic removed. (load_rcfile): Pass only two arguments to read_eval_stream. * parser.h (read_eval_stream): Declaration updated. * txr.c (remove_hash_bang_line): Function removed.

Open the file, and check for a hash bang line, doing the special processing which can generate more arguments from material after a null byte in the hash bang line. The parse_stream variable is now initialized to nil and doubles as a Boolean indicating whether a stream has been opened. After the loop, we remove the script file from the arguments, if we have an open stream and the spec_file_str matches. read_eval_stream is called only with two arguments. * txr.1: Revised existing documentation and described new features.

* Bugfix: missing warnings when main file is .txr.Kaz Kylheku2017-03-221-2/+2
| | | | | | | | | | | | | | | | | | | If the main file of an application is a .txr file, unbound function and variable warnings are not being generated. * match.c (v_load): For consistency with the load function in eval.c, release deferred warnings in the normal return case, if we are not a recursive load. However, this doesn't fix anything because a load or include is always recursive being invoked from a .txr file that is being loaded. The problem is in fact that the recursive flag is nil when it shouldn't be, and then the uw_unwind block obliterates the warnings. * txr.c (txr_main): We must bind *load-recursive* to t around not just the loading of Lisp, but also of TXR. Otherwise the individual loads will release warnings, raising false positives for forward references.
* Better way for releasing deferred warnings.Kaz Kylheku2017-02-101-2/+2
| | | | | | | | | | | | | | | | | | | | We should be re-throwing deferred warnings as ordinary warnings, not dumping them to a stream. * eval.c (eval_exception): Use uw_release_deferred_warnings instead of uw_dupm_deferred_warnings. (load): Likewise. * parser.c (read_eval_ret_last): Likewise. * txr.c (txr_main): Likewise. * unwind.c (uw_release_deferred_warnings): New function. * unwind.h (uw_release_deferred_warnings): Declared. * txr.1: Documented release-deferred-warnings and updated documentation for dump-deferred-warnings.
* Suppress undef warnings in command line file.Kaz Kylheku2017-01-291-0/+3
| | | | | | * txr.c (txr_main): Bind sys:*load-recursive* to t before reading and evaluating forms, then bind to nil before entering repl.

* Enable unbound warnings when expanding TXR code.Kaz Kylheku2017-01-221-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this change, Lisp expansion-time warnings are no longer suppressed during the parsing of the TXR pattern language. Embedded Lisp expressions can refer to TXR pattern variables, which generates spurious warnings that must be suppressed. Since TXR pattern variables are dynamically introduced in a very flexible way, it's hard to do an exact job of this. We take the crude approach that warnings are suppressed for all pattern variables that appear anywhere in the TXR code. To do that, we identify, at parse time, all directives which can bind new variables, and register those variables as if they were tentative global defs, purging all pending warnings for them. * match.c (binding_directive_table): New static hash table. (match_reg_var, match_reg_params, match_reg_elem): New functions. (match_reg_var_rec): New static function. (dir_tables_init): gc-protect binding_directive_table, and populate its entries. * match.h (into_k, named_k): Declared. (match_reg_var, match_reg_params, match_reg_elem): Declared. * parser.y (process_catch_exprs): New static function. (elem): Call match_reg_elem for each basic directive, to process the variables in that directive according to its operator symbol. Do this for each compound form elem and variable elem. Te horizontal @(define) eleme has its own grammar production here, and we handle its parameter list in that rule. (define_clause): Handle the parameters of a vertical @(define). It binds pattern variables, and so we must suppress unbound warnings for those. (catch_clauses_opt): Process the parameters bound by @(catch) clauses. (output_clause): Suppress warnings for the variables nominated by any :into or :named argument. (expand_repeat_rep_args): Suppress warnings for :counter variable, and for :vars variables. (parse_once): Remove the warning-muffling handler frame set up around the yyparse call. * txr.c (txr_main): Suppress warnings for TXR variables defined using -D syntax on the command line. Dump deferred warnings after parsing a .txr file.
* Streamline repeated intern call in txr_main.Kaz Kylheku2017-01-221-3/+4
| | | | | * txr.c (txr_main): Reduce three repetitions of the same call to intern to one call.
* Deferred warnings.Kaz Kylheku2017-01-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Warnings about undefined functions and variables are now deferred during loading, so forward references do not generate nuisance diagnostics. * eval.c (load_recursive_s): New symbol variable. (eval_defr_warn): New static function. (op_defvarl, op_defun): Purge any deferred warning about the given function or variable not being defined. (load): Rebind the sys:*load-recursive* special var to true around the load. After the load, dump deferred warnings if the prior binding of sys:*load-recursive* is false. Discard deferred warnings in the case of termination by a nonlocal control transfer. (do_expand): Treat unbound vars and functions as deferrable warnings, specially tagged for individual purging frkm the deferred list. (eval_init): Intern sys:*load-recursive* and initialize load_recursive_s variable. * eval.h (load_recursive_s): Declared. * parse.c (repl_warning): Accept variable arguments. Check whether we are loading and if so, defer deferrable (repl): Adjustment for altered signature of repl_warning. warnings. * txr.c (txr_main): dump deferred warnings after evaluating Lisp stream. * unwind.c (deferred_warnings): New static variable. (uw_throw): When a deferrable warning is caught, suppress the usual message and add it to the deferred_warnings list. (uw_defer_warning, uw_dump_deferred_warnings, uw_dump_deferred_warnings, uw_purge_deferred_warnings): New functions. (uw_late_init): gc-protect deferred_warnings. * unwind.h (uw_defer_warning, uw_dump_deferred_warnings, uw_dump_deferred_warnings, uw_purge_deferred_warnings): New functions declared.
