ENCODED BY Issue #316

Closed ErfanBabakhani closed 1 month ago

ErfanBabakhani commented 2 months ago

hello when I try compile this code I give tc.asn:6:4: error: missing R_PAREN at 'ENCODED' error : (Doe's your compiler support ENCODED BY constraint?) (I tried the given code by OSS NOKALVA compiler and it has no problem with it)

RectangleModule1 DEFINITIONS AUTOMATIC TAGS ::= BEGIN

Erf ::=INTEGER (0..1) Ex1 ::= OCTET STRING ( CONTAINING Erf ENCODED BY {joint-iso-itu-t(2) asn1(1) packed-encoding(3) basic(0) aligned(0)})

enc-PER-Aligned OBJECT IDENTIFIER ::= {joint-iso-itu-t(2) asn1(1) packed-encoding(3) basic(0) aligned(0)}

Ex2 ::= BIT STRING ( CONTAINING IA5String (SIZE(0..8)) ENCODED BY enc-PER-Aligned)

END

No, asn1scc does not support this directive. The encoders are specified with the command line (either uPER, ACN or XER). aPER could perhaps be achieved using ACN using the align-to-next keyword (to be tested)...

What about informtion object class ? I think it's better to clarify types and features your compiler support and wich not supported in your doc. https://taste.tuxfamily.org/wiki/index.php?title=Technical_topic:_ASN.1_-_An_introduction_to_ACN
