We need a prototype of yylex that is in scope of the grammar,
but YYSTYPE is not defined there.
* parser.l: Bison 3 declares yyparse in y.tab.h, so we have to
reorder some #includes.

* parser.l (YY_INPUT): Stop relying on removed yyin_stream;
refer to stream via yyextra.
(yyin_stream, lineno, errors, spec_file_str,
prepared_error_message): Global variables removed.
(yyget_column, yyset_column): Missing prototypes not generated by flex
in bison bridge mode have to be added by us to avoid
warning.
(yyerror): Takes parser and scanner as parameters. Prepared error
message is now in the parser context. Calls to other error handling
functions receive scanner context.
(yyerr): New function.
(yyerrorf, yyerrprepf): Takes scanner argument, chases extra data to
get to parser, and refers to parser variables instead of globals.
(num_esc): Scanner argument added.
(%option reentrant, %option bison-bridge, %option extra-type): New
flex options.
(grammar): yyscanner added everywhere.
(end_of_char): Takes scanner argument.
(parse_init): Removed references to yyin_stream and
prepared_error_message.
(parse_reset): Function renamed to open_txr_file. Returns
results via pointers instead of setting global variables.
(regex_parse, lisp_parse): Use reentrant parser interface.
* parser.y (yyerror): Prototype removed.
(yylex): Prototype moved after grammar, with new arguments.
(sym_helper, define_transform): Take scanner argument.
(make_expr): Takes parser argument.
(rlrec): New static function.
(rl): Function turned into macro.
(mkexp, symhlpr): New macros.
(%purse-parser, %parse-param, %lex-param): New Yacc options.
(grammar): Actions re-worked for reentrance. Parser and scanner
contexts are passed down to helper functions, in some cases
via the three new macros. The result of the parse is stored
in the syntax_tree member of the parser_t structure instead
of a global. The yylex function receives the scanner instance.
(get_spec): Function removed.
(parse): New function.
* parser.h (lineno, errors, yyin_stream, spec_file_str):
Declarations removed.
(parser_t): New struct.
(yyerr): New function declared.
(yyparse, yyerror, yyerrorf, end_of_regex, end_of_char,
yylex, yylex_destroy): Declarations updated.

(sig_handler): Increment and decrement interrupt count.
If the interrupt count is already positive, treat
that as if async signals were not enabled: do not
invoke handlers.

Added check for setitimer/getitimer which also
checks for <sys/time.h>.
* signal.c (sig_init): Register itimer-real, itimer-virtual,
itimer-prof variables and getitimer and setitimer functions.
(tv_to_usec): New static function.

except for signals for which we use alt stack.
* signal.h (sig_save_enable): Do sig_check before
enabling async signals. This caused the !async_sig_enabled assertion
to trip inside make_obj.

replace with do { } while (0), since we don't have any instances of a

executable, whether this is due to being required to use C99.
For instance, the Solaris environment requires compilation
using the C99 dialect if _XOPEN_SOURCE is set to 600 or higher.

stack for SIGBUS also, not only for SIGSEGV. On Linux,
when stack growth collides with another memory mapping,
it triggers a SIGBUS not SIGSEGV, which occurs when the
process limit on stack size is exceeded. In either
situation, we need an alternative stack.

like other situations that evaluate TXR Lisp from the pattern language.
Otherwise obscure things will go wrong.
(h_do): Same as above, and additionally, add the forgotten
call to install the bindings into the match context.
|
|
|
|

It should be returning next_spec_k, rather
than bindings, which indicate a complete match.

integers and floating literals.
* genvin.txr (txr_num): The general solution is to over-match
a number by one character: a non-token constituent, and then
subtract that from the highlight region using me=e-1.
This solves the prefix ambiguities between numbers and symbols.
(txr_badnum): New match: matches floating literals with trailing
junk, which are highlighted as errors.
(txr_directive, txr_list, txr_bracket, txr_mlist, txr_mbracket):
All of these contain a txr_badnum.
