Subject: ASN.1 extension marker in Convert::ASN1 - feature request and/or volunteering

Hi, I found your CPAN module to encode/decode ASN.1. It's great, and saved me probably a week of coding! I'm trying to write future-proof ASN.1, and I read about the "extension marker" that basically tells the "old" parser that there may be unknown tags here. I browsed through the source code of the module, but couldn't find support for this feature in your code. Is this correct, or am I just overlooking it? Will you accept a patch that introduces this feature?

I am not familiar with the "extension marker" you are referring to, but I would certainly consider any patch. If possible please fork the project on github at https://github.com/gbarr/perl-Convert-ASN1 and send a pull request Graham.

It's a backward/forward compatibility thing: v1 ::= SEQUENCE { a INTEGER, b INTEGER, ... } v2 ::= SEQUENCE { a INTEGER, b INTEGER, c INTEGER OPTIONAL, ... } By marking the c-field OPTIONAL, a v2-decoder can read a v1 message (backward compatible). The extension marker "..." tells a v1 encoder "there may be more stuff here, please ignore", allowing it to understand a v2 message (forward compatibility). See for a much longer explanation: http://lionet.info/asn1c/blog/2010/09/21/question-extensibility-removing-fi elds/ Show quoted text

Ah, so my work will not be in vain. Show quoted text

Done (the forking part at least) Thx for the quick response, Niels *** Disclaimer *** Vlaamse Radio- en Televisieomroeporganisatie Auguste Reyerslaan 52, 1043 Brussel nv van publiek recht BTW BE 0244.142.664 RPR Brussel http://www.vrt.be/gebruiksvoorwaarden

OPTIONAL is already supported. See http://cpansearch.perl.org/src/MARSCHAP/perl-ldap-0.44/lib/Net/LDAP/ASN.pm Graham.
