Cannot parse PKIX1Explicit-2009.asn: (token "2"): syntax error, unexpected number
When trying to parse PKIX1Explicit-2009.asn from https://github.com/P1sec/pycrate/blob/master/pycrate_asn1dir/IETF_PKI_RFC5911/PKIX1Explicit-2009.asn, the following error is thrown:
[minfrin@bob asn1]$ ~/src/asn1/asn1c-trunk/asn1c/asn1c -E -F ./tmp/pycrate-master/pycrate_asn1dir/IETF_PKI_RFC5911/PKIX1Explicit-2009.asn ASN.1 grammar parse error near ./tmp/pycrate-master/pycrate_asn1dir/IETF_PKI_RFC5911/PKIX1Explicit-2009.asn:263 (token "2"): syntax error, unexpected number Cannot parse "./tmp/pycrate-master/pycrate_asn1dir/IETF_PKI_RFC5911/PKIX1Explicit-2009.asn"
Is this a known issue?
You can read from asn1p_y.y, it does not support versionNumber: inside [[ ]]
As a result of this bug, it is not possible for asn1c to parse the schemas from https://tools.ietf.org/html/rfc5912#section-14.
I'm seeing the same problem here, which makes it difficult to use asn1c to handle anything that depends on RFC 5912 as well.
To be specific, i'm running into this problem while trying to add support for x25519 and Ed25519 (from rfc 8410) to certlint, which depends on asn1c.
@brchiu, do you have any suggestion for how to adapt asn1p_y.y to support versionNumber inside [[ and ]]?
Looks like it has to do with TOK_VBracketLeft and TOK_VBracketRight, those only look usable in conjunction with ComponentTypeLists, and i don't understand yacc/etc well enough to know how to add it.
