I want to know how to use this library and function in this library to parse asap2(a2l) ?

Could you share me some reference about the Asap2 library to use it ？

Hi friend. CR4-642.a2l can not parse. have errors . File: https://file.io/dBreoDfQLeDz

The grammar is identifying the RESERVED PrgType as token which makes the parser fail.
E.x.: (I renamed the segment name and description)
/begin MEMORY_SEGMENT nameofsegment "description" RESERVED

The error from the library:
… Line: 926 : Row: 66 : Syntax error, unexpected RESERVED, expecting IDENTIFIER

Hello, I use Asap2 to parse a v1.7 a2l file, it report error when meet MATRIX_DIM like this:
MATRIX_DIM 1 200

I have check the specification, the MATRIX_DIM have fix 3 member x,y,z in v1.6, but v1.7 define like this:
MATRIX_DIM (uint Dim)+

The count of Dim can be 1,2,3,......

So I change my local project, in file Asap2.Language.grammar.y line 1194-1197 change to
matrix_dim : MATRIX_DIM NUMBER {
$$ = new MATRIX_DIM(@$, (uint)$2);
}
;

matrix_dim : MATRIX_DIM NUMBER NUMBER {
$$ = new MATRIX_DIM(@$, (uint)$2, (uint)$3);
}
;

matrix_dim : MATRIX_DIM NUMBER NUMBER NUMBER {
$$ = new MATRIX_DIM(@$, (uint)$2, (uint)$3, (uint)$4);
}
;

And class MATRIX_DIM in file Asap2File.cs change to
[Base(IsSimple = true)]
public class MATRIX_DIM : Asap2Base
{
public MATRIX_DIM(Location location, uint xDim, uint yDim, uint zDim) : base(location)
{
_Dims.Add(xDim);
_Dims.Add(yDim);
_Dims.Add(zDim);
Dims_str = xDim.ToString() + " " + yDim.ToString() + " " + zDim.ToString();
}
public MATRIX_DIM(Location location, uint xDim, uint yDim) : base(location)
{
_Dims.Add(xDim);
_Dims.Add(yDim);
Dims_str = xDim.ToString() + " " + yDim.ToString();
}
public MATRIX_DIM(Location location, uint xDim) : base(location)
{
_Dims.Add(xDim);
Dims_str = xDim.ToString();
}
[Element(0, IsArgument = true)]
public string Dims_str = "";
public List _Dims = new List();
}

Now it work for my a2l file, but the count of MATRIX_DIM is limit to 3, is there a better solution?

What is the license for the code in this project?

https://help.github.com/articles/adding-a-license-to-a-repository/

I think the MIT License is a good choice.

            0xa086e5b2
            1
         /end IF_DATA
      /end CHARACTERISTIC

The parser does not like the "1.e-002".
Syntax error, unexpected IDENTIFIER, expecting NUMBER

@kallemooo There is a package on NuGet that references this repository, but appears to be published by someone else?

https://www.nuget.org/packages/Asap2/

If it's you, then update the readme, if not, contact the publisher and get the package re-assigned to this you and/or publish your own package.

Hi:

Thanks for you lib!

I found software crash when a2l include following txt:
/begin RECORD_LAYOUT SWORD_COL_DIRECT
FNC_VALUES 1 SWORD COLUMN_DIR DIRECT
ALIGNMENT_WORD 2
ALIGNMENT_LONG 2
ALIGNMENT_FLOAT32_IEEE 2
ALIGNMENT_FLOAT64_IEEE 4
/end RECORD_LAYOUT

It seems the problem come from Asap2Files.cs line 816
[Element(1, IsDictionary = true)]
public Dictionary<string, ALIGNMENT> alignments;
So I change it to :
[Element(1, IsDictionary = true)]
public Dictionary<string, ALIGNMENT> alignments = new Dictionary<string, ALIGNMENT>();

The software can work normally now. Is my modification correct?

I tried this A2L parsing utility on one of my A2L's, and it errored out, stating that an IF_DATA keyword was unexpected in an AXIS_PTS. I believe this is valid A2L syntax per ASAM MCD-2 MC. See https://www.asam.net/standards/detail/mcd-2-mc/wiki/.

I am pretty new to LEX/YACC, but i think maybe the error is on line 498 of Asap2.Language.grammar.y?

| axis_pts if_data {

should be

| axis_pts_data if_data {

Maybe?

Otherwise this is an awesome tool - thanks for making it available!

Hi!
First of all, great Lib!

Do you have plans to update the code base to support current A2L specification 1.7.1?

There were some changes, see at the bottom of the site (Release Presentation):
