How do I best tell yacc to expect a Rune? For example, defining a
“colon-equals” assignment operator with
%right L'≔'
then adding it to the grammar with
expr: NUMBER
| VAR { $$ = mem[$1]; }
| VAR L'≔' expr { $$ = mem[$1] = $3; }
You need to treat non-ASCII UTF-8 the same way
that you treat multiple characters. That is, you
implement '≔' the same way you'd implement ':=' or '+=':
in the lexer as a named symbol like NUMBER and VAR.
Then what does yacc(1) mean when it says that yacc accepts UTF input?
Why should the
As an aside, my yylex code included:
if(c == '.' || (isascii(c) isdigit(c))){
Bungetc(src);
yylval = charstod(getc, 0);
Bungetc(src);
return NUMBER;
}
where getc was a simple wrapper around Bgetc(2) for compatibility
I just tried your program and it worked fine for
me once I changed yylex to return actual Unicode
values instead of byte values. (There is a difference
between Bgetc and Bgetrune.)
D’oh!
Depending on how I write the constants, yacc may or may not accept
the grammar, and when it does
