Hello,

Is there a way to create the following structure?

<AR-PACKAGE>
  <SHORT-NAME>Constants</SHORT-NAME>
  <ELEMENTS>
    <CONSTANT-SPECIFICATION UUID="9B2B418A-CA6C-4E3B-9562-D49D1C2695B1">
      <SHORT-NAME>CDiagNv_NvMServiceRequestType</SHORT-NAME>
      <VALUE-SPEC>
        <ARRAY-VALUE-SPECIFICATION>
          <ELEMENTS>
            <RECORD-VALUE-SPECIFICATION>
              <FIELDS>
                <NUMERICAL-VALUE-SPECIFICATION>
                  <SHORT-LABEL>ServiceId</SHORT-LABEL>
                  <VALUE>0</VALUE>
                </NUMERICAL-VALUE-SPECIFICATION>
                <NUMERICAL-VALUE-SPECIFICATION>
                  <SHORT-LABEL>RequestResult</SHORT-LABEL>
                  <VALUE>0</VALUE>
                </NUMERICAL-VALUE-SPECIFICATION>
              </FIELDS>
            </RECORD-VALUE-SPECIFICATION>

I tried creating array data type, record data type and RECORD-VALUE-SPECIFICATION and ARRAY-VALUE-SPECIFICATION are reversed.

I found a mismatch behavior, for tooling convention like a System Desk from DSpace it's possible to create a description attribute inside Record elements.
So to solve those issue i suggest to add between line 84 and 85 of file datatype_writer.py the following code:

tmp = self.writeDescXML(childElem)
if tmp is not None: lines.extend(self.indent(tmp,3))

This is the same code are used in other classes.

Hi all, great package - thank you!

I am updating a script that was at 0.4 with PyCharm. The make_packages call takes a comma separated list of package name strings but the type hint in the function definition says '*refs: list[str]'. This causes PyCharm to flag the call with a warning since I am not passing a list of strings but the comma separated strings themselves.

Let me know if you'd like me to make a pull request with this change.

Thank you.

hi,
i was playing around with autosar and was pretty happy about this nice packages.
But still some element missing.
Question: did i got a wrong version?

e.g.

INCOMPAT_TAGS = [
    'LONG-NAME',
    'DESC',
    'PROVIDER-IREF',
    'SDG-CAPTION',
    'SDX-REF',
    'CATEGORY',
    'CLIENT-ID-DEFINITION-SET-REFS',
    'CONTAINER-I-PDU-HEADER-BYTE-ORDER',
    'ECU-EXTRACT-VERSION',
    'FIBEX-ELEMENTS',
    'MAPPINGS', # todo for each self.parseSystemMapping?
    'PNC-VECTOR-LENGTH',
    'PNC-VECTOR-OFFSET',
    'ROOT-SOFTWARE-COMPOSITIONS',
    'SYSTEM-VERSION',
    'REQUESTER-IREF']

Hello cogu,

and greets to Sweden.

Currently I am loading real-world example and came across several NotImplementedErrors, e.g. for:

• DIAGNOSTIC-EVENT-NEEDS
• SUPERVISED-ENTITY-NEEDS
• BSW-MGR-NEEDS
• CATEGORY
• ECU-EXTRACT-VERSION
• etc.

Then I realized that I was parsing a AUTOSAR_00049 file instead of AUTOSAR_4-2-2

My questions are:

• How have you planned to support several versions of XSDs in one tool? Should the parser only expect the items defined in XSD or should it be in "umbrella" mode -> so take what is known. Both strategies seem to be not supported yet (at least parser seems to be quite sensible on anything unknown and parsing is workspace version independent)
• I am currently wondering if I should create a fork for introducing some AUTOSAR_00049 measures or make the tool more upwards compatible and less strict or if that strategy ever gets the chance of a pull request by creating a branch here. What is your suggestion?

Best regards,
Tom

ComSpec for individual data elements in a port cannot be created

I am reading ARXML we have generated and it is not to the Reader's liking. I have iterated through fixing each raised exception. A nice feature would be a 'parse-only' flag that would return a list of all lines in an ARXML file needing attention and why it is a problem.

Runnables, events etc. for AUTOSAR 4

        # record = autosar.constant.RecordValue(label, parent=parent)

change to
record = autosar.constant.RecordValueAR4 (label, parent=parent)

in file b \Lib\site-packages\autosar-0.3.11-py3.9.egg\autosar\writer\component_writer.py:365
应该改为
lines.append(self.indent('{}'.format(self.toBooleanStr(comspec.useEndToEndProtection)), 1))
否则 arxml文件E2E的属性无法正常解析

Hi @cogu

Before starting, I'm big fan of your autosar module and it's very useful for my works.
As far as i know, ImplementationDataTypeElement can have subElement like belows.

Is it possible to generate above code by using your module? If not, you have some plans for support? (I hope module had createImplementationDataElement APIs)
Thank you in advance

Using collections.Iterable or collections.Mapping direct is deprecated since Python 3.3. In future versions will it stop working.

Change to use collections.abc.Iterable or collections.abc.Mapping will solve this issue.

In the AUTSAR XSD schema the property "BASE-TYPE-SIZE" is optional. In the Python code it is mandatory.

Hello,I'm trying to preconfigure,But there was a problem with the last part

As you can see in the picture,What should I do, please

Hi cogu:
I am parai, and I am using this project branch feature/ar4_api for my own AUTOSAR project https://github.com/parai/as which is a study platform of AUTOSAR with python toolchain support for the BSW configuration and CAN COM/DCM/BOOTLOADER tools.
Now I am trying to use your project as RTE configuration and related C source code generator. So I started from the tutorial2, but I failed as below exception, could you help to have a look and how to fix this issue.

And the major feature I want is the RTE C source code generator, can you provide much more demo on this?

Hi, First thanks to the contributors for this lib. it's very useful.
I have an issue when loading ARXML file. when i use loadpackage the package is correctly loaded but the elements are staying empty. In the same time in the subpackages elements are loaded perfectly.
If somebody know what is my mistake i will be thankfull !
here the simple code that I a use for the loading :
ws = autosar.workspace("4.1.1") ws.openXML("myfile.arxml") for role in ws.listPackages(): ws.loadPackage(role)

I tried with differents files but I have the same issue each time

Hello,

i have 3 questions:

1. Is there a way to add to an element?
2. It is possible to create Provider receiver port?
3. Why i can not crate ProvidePort if i have many elements in a PortInterface?

Thank you,
Tofeni

The current parser incorrectly parses the schema version. Make a fix for this.

Create API methods to allow users to programattically create new AR4 components, data types etc.

the demo always has error,about module 'autosar' has no attribute 'workspace'

Traceback (most recent call last):
File "C:\Users\gz03232\Documents\autosar.py", line 1, in
import autosar
File "C:\Users\gz03232\Documents\autosar.py", line 3, in
ws = autosar.workspace(version='4.2.2')
AttributeError: module 'autosar' has no attribute 'workspace'

demo application as follow:
import autosar

ws = autosar.workspace(version='4.2.2')

ws.createPackage('DataTypes', role='DataType')
ws.createPackage('Constants', role="Constant")
ws.createPackage('PortInterfaces', role="PortInterface")
ws.createPackage('ModeDclrGroups', role="ModeDclrGroup")
ws.createPackage('ComponentTypes', role='ComponentType')

#save the file as XML
ws.saveXML('Workspace.arxml')

ws = autosar.workspace(version='4.2.2')

ws.createPackage('DataTypes', role='DataType')
ws.createPackage('Constants', role="Constant")
ws.createPackage('PortInterfaces', role="PortInterface")
ws.createPackage('ModeDclrGroups', role="ModeDclrGroup")
ws.createPackage('ComponentTypes', role='ComponentType')

#save workspace packages into XML files
ws.saveXML('DataTypes.arxml', filters=['/DataTypes'])
ws.saveXML('Constants.arxml', filters=['/Constants'])
ws.saveXML('PortInterfaces.arxml', filters=['/PortInterfaces', '/ModeDclrGroups'])
ws.saveXML('ComponentTypes.arxml', filters=['/ComponentTypes'])

XML parse/write AR 4 component types (including behavior)

Hi, I use the example like as bellows:
import autosar

#Create some packages and data types

ws = autosar.workspace('4.2.2')
datatypes = ws.createPackage('DataTypes', role='DataType')
basetypes = datatypes.createSubPackage('BaseTypes')
u8Type = basetypes.createSwBaseType('uint8', 8, nativeDeclaration='uint8')
u16Type = basetypes.createSwBaseType('uint16', 16, nativeDeclaration='uint16')
u32Type = basetypes.createSwBaseType('uint32', 32, nativeDeclaration='uint32')
ws.saveXML('basetypes.arxml')

#Print reference and name for the created objects
print('u8Type.name: ' + u8Type.name)
print('u8Type.ref: ' + u8Type.ref)
print('u16Type.name: ' + u16Type.name)
print('u16Type.ref: ' + u16Type.ref)
print('u32Type.name: ' + u32Type.name)
print('u32Type.ref: ' + u32Type.ref)

and it fails with:
d = Decimal(float(version))
ValueError: could not convert string to float: '4.2.2'

Hello @cogu
I am new to the AUTOSAR world and was wondering do you have any plans to support AUTOSAR 4.4.0 version? Many thanks in advance.

First thanks for this great package. For AR 4.x the element name of an complex driver component type shall be "COMPLEX-DEVICE-DRIVER-SW-COMPONENT-TYPE'" instead of "COMPLEX-DEVICE-DRIVER-COMPONENT-TYPE". See /autosar/parser/component_parser.py

there is no api to set swc “DATA-TYPE-MAPPING-REF ”

After I use
pip install autosar.xml and run the code with import autosar.xml, the python says no module name autosar.xml

with below data in arxmls

FIBEX-ELEMENTS
FIBEX-ELEMENT-REF-CONDITIONAL

With a glance of the code, I found you generate the arxml by hand. Is there any plan to port the writer to lxml? I personally use lxml to generate arxml and the pretty_print can perfectly fit the AUTOSAR indentation standard.

i want to load create RPort in A workspace's componentType, using Port interface in another arxml.
how to create one workspace with multiply arxmls.
how to load multiply arxmls into one workspace.

thanks

variantProps needs to be initialized to None, too.

Otherwise, my call to createRequirePort(name, if_name, comspec=comspecs) results in an error.

(Sorry for not providing a PR. I did a dirty hack which makes it work for me w/o any other testing.)

partition_test_disabled.py cause AttributeError: module 'autosar.portinterface' has no attribute 'ModeGroup', partition_test_disabled.py is too old?

Now to implement such a function when writing data to the NVM after shutdown, a wake-up source is detected, and the controller will wake up again at this time the ECU will be reseted again. and the data in NVM is incomplete. At this time, the RAM will reload the previous data in NVM after reset, but at this time we do not want to use Nvm_ReadAll () to read the previously stored data from NVM, but want to keep the last unsaved data in RAM

Hello,

i have to generate an arxml file, which will be imported in a davinci workspace.

I can not find a function to create an NV_DATA_INTERFACE element.
Can someone tell me if this can be done or not, and if it will be implemented in a future version?

Here is a model how it is look like:

Thank you,
Marius

Release v0.3.7 do not work on Python v 3.5 and older.

Tested on Python v 3.4.3

Not able to create the numerical value variation point for PortApi.

i need to create 1)port defined argument value
2)Numerical value specification
3)numerical value variation point

The current parser uses the lightweight standard API xml.etree.ElementTree that support the current needs of the library.

One problem with the current parser is that on an ARXML error there is no feedback on where in the input files the problem is found.

Using the etree module from lxml instead more accurate error information can be printed as the lxml keeps track of xml element file location.

Changing line 1 in base.py to
from lxml import etree as ElementTree
its all that is needed to use lxml. The API is compatible and I tested with the current unit tests and all test passes.

lxml do also support XML schema and schema validation. With lxml as base schema validation can be added.

Getiing Error as follows:
AttributeError: 'Package' object has no attribute 'createImplementationDataType'

Have you considered using pyecore as infrastructure? It looks like a good fit for this project.

I would like to generate a DEXT (Autosar Diagnostic Extract) like file using Python and one library.
Is there an extension to this library or something similar that can help me?

Thank you!

In order to better support what parts of the data model goes into the XML file when saving it we need better control. Currently we have the packages=[] attribute but that is clearly not good enough.

Proposal is to replace packages attributes with a filters attributes where filters attribute can give the user the ability to control even on individual element level (instead of package level) what goes into the XML.

I want to read an existing element: ECUC-MODULE-CONFIGURATION-VALUES with the SHORT-NAME Dcm but it gives the following error:

Does this means this is not supported?
