2017-02-21encode/decode: Include the stack trace in error returnsBjörn Gustavsson
The generated encode/2 and decode/2 functions can return cryptic error messages. Consider this ASN.1 spec: T DEFINITIONS AUTOMATIC TAGS ::= BEGIN S ::= SEQUENCE { b BOOLEAN, i INTEGER (1..100), j INTEGER (0..7), s OCTET STRING } END In OTP 19, the error terms will look like this: Eshell V8.2 (abort with ^G) 1> asn1ct:compile('T', [ber]). ok 2> rr('T'). ['S'] 3> 'T':encode('S', #'S'{}). {error,{asn1,{encode_boolean,undefined}}} 4> 'T':encode('S', #'S'{b=false}). {error,{asn1,{encode_integer,undefined}}} 5> 'T':encode('S', #'S'{b=false,i=7,j=0}). {error,{asn1,function_clause}} Some error terms are clearer than other. In the first error term, it is clear that the error refers to the 'b' field, since there is only one BOOLEAN in 'S'. The second error term could refer to either 'i' or 'j'. The last error term... well... in this case we can infer that it must refer to 's'. The easiest way to provide more information is to include the stack trace with line numbers in the error term: 3> 'T':encode('S', #'S'{b=false}). {error,{asn1,{{encode_integer,undefined}, [{'T',encode_integer,2,[{file,"T.erl"},{line,240}]}, {'T',enc_S,2,[{file,"T.erl"},{line,102}]}, {'T',encode,2,[{file,"T.erl"},{line,36}]}, {erl_eval,do_apply,6,[{file,"erl_eval.erl"},{line,674}]}, {shell,exprs,7,[{file,"shell.erl"},{line,686}]}, {shell,eval_exprs,7,[{file,"shell.erl"},{line,641}]}, {shell,eval_loop,3,[{file,"shell.erl"},{line,626}]}]}}} By looking at the generated Erlang code, we can see that encoding failed for 'i'. This is an compatible change. All that the documentation says is that the format of the error tuple is: {error,{asn1,Description}} With this change, Description is always a tuple: {ErrorDescription,StackTrace} Alternatives considered: Providing more information in the error term itself and make sure there can be no 'function_clause', 'badarg', or 'badmatch' exceptions. That would be possible, but it would require a lot of work and it would increase the size of the generated code and make it slower. Therefore, this solution was rejected.
2017-02-06Teach the ASN.1 compiler the 'maps' optionBjörn Gustavsson
When the 'maps' option is given, the SEQUENCE and SET types are represented as maps instead of as records. Optional and default values must be not be given as asn1_NOVALUE or asn1_DEFAULT in a map passed to the M:encode/2 function; they must be omitted from the map. Similarly, when decoding missing values will be omitted from the map. No .hrl files will be generated when the 'maps' options is used. That means values in an ASN.1 module must be retrieved by calling the appropriate function in generated module. Since we one day hope to get rid of the options 'compact_bit_string', 'legacy_bit_string', and 'legacy_erlang_types', we will not allow them to be combined with the 'maps' option.
2017-01-13asn1: Remove deprecated functionsBjörn Gustavsson
Remove the entire asn1rt module. All functions in it were deprecated in OTP 17. In asn1ct, remove the deprecated functions asn1ct:encode/3 and asn1ct:decode/3. Also remove asn1ct:encode/2, which has not been formally deprecated but is undocumented.

2014-03-28Consistenly use ASN.1 instead of asn1Björn Gustavsson
When talking about the ASN.1 standard, ASN.1 specifications, and the ASN.1 compiler, consistently use "ASN.1" instead of "asn1".

2014-03-28Correct description of the REAL typeBjörn Gustavsson
REAL is implemented, sort of. But real numbers must be given in a string.
2014-03-28Replace "extend-ability" with "extensibility"Björn Gustavsson
While "extendability" (without the hyphen) is an English word, "extensibility" is the established term used when talking about the extensibility of ASN.1 types.
2014-03-28Remove the section about encoding rulesBjörn Gustavsson
The section about encoding rules serves no useful purpose. Most users already know which encoding rule to use for their specifications. The few users that have their own specification and need to decide on which encoding rule to use will need much more information.
2014-03-28Bring information about tags up to dateBjörn Gustavsson
Since 1994 when the AUTOMATIC TAGS was introduced, ASN.1 users no long need to worry about tagging, and the following sentence no longer makes any sense: It is essential for all users of ASN.1 to understand all the details about tags. Therefore, remove the entire existing section of tags, and replace it with a shorter section explaining why we no longer need to know about tags. Remove all tags from the examples.
