Subject: Convert::ASN1
Hi
Excuse me if this isn't the correct list for the
Convert::ASN1 module.
I was using the library Convert::ASN1 and
get an error trying to prepare a "SET OF xxxx OPTIONAL".
A little example:
--------------------------------------
#!/usr/local/bin/perl -w
use Convert::ASN1;
my $asn = Convert::ASN1->new;
$asn->prepare( q<
foo ::= SET
{
bar [0] SET OF INTEGER OPTIONAL
}
Show quoted text
>) or die "Convert::ASN1 ERROR " . $asn->error . "\n";
print "OK \n";
---------------------------------------
The problem seems to be only "SET OF xxxx OPTIONAL", because
the same statement works without the "OPTIONAL" keyword.
Am I doing something wrong?
It's a valid construction?
I found in the grammar file: 'parser.y'
in the line 134
selem : seqset OF class plicit sselem
Shouldn't it said something like
selem : seqset OF class plicit sselem optional ?
I will search if there are any side efects.
Thanks for your attention

Well Convert::ASN1 does not have its own list, so here is as good as any.

probably not

It probably should be.

I cannot think of any side effects. But to compile the parser
you will need a version of byacc that can generate perl code.
You can get it from http://www.cpan.org/src/misc/perl-byacc1.8.2.tar.gz
To rebuild the parser run make run_byacc

Here is (i think) a solution.
I added in the parser.y file, for the selem definition
the optional keyword, and added the cOPT definition
to the element.
I've tried, and seems to be working.
(there are two warning whith the perl_byacc
and the test t/05time.t failed (with/without my patch))
