Migration from v1.x to v2.0

Version 2.0.0 includes breaking changes to CLI arguments. Here's how to migrate:

Old: Generate mapping

autosar-extract input.pdf -o output.md --generate-mapping

New:

autosar-extract input.pdf --mapping output.md

Old: Generate hierarchy

autosar-extract input.pdf -o output.md --include-class-hierarchy

New:

autosar-extract input.pdf --hierarchy output.md

Old: Generate class details

autosar-extract input.pdf -o output.md --include-class-details

New:

autosar-extract input.pdf --class-details output/

Old: Combine mapping + hierarchy

autosar-extract input.pdf -o output.md --generate-mapping --include-class-hierarchy

New:

autosar-extract input.pdf --mapping mapping.md --hierarchy hierarchy.md

Note: The --generate-mapping flag conflicts with --include-class-details and --include-class-hierarchy. These options cannot be used together.

Python API

You can also use the package programmatically in your Python code:

from autosar_pdf2txt import PdfParser, MarkdownWriter, MappingWriter

# Parse single PDF file
parser = PdfParser()
packages = parser.parse_pdf("path/to/file.pdf")

# Parse multiple PDF files
parser = PdfParser()
all_packages = []
for pdf_path in ["path/to/file1.pdf", "path/to/file2.pdf"]:
    packages = parser.parse_pdf(pdf_path)
    all_packages.extend(packages)

# Write package hierarchy to markdown
writer = MarkdownWriter()
markdown = writer.write_packages(all_packages)
print(markdown)

# Generate class inheritance hierarchy
from autosar_pdf2txt import AutosarClass

# Collect all classes from packages
all_classes = []
for pkg in all_packages:
    classes_from_pkg = writer._collect_classes_from_package(pkg)
    all_classes.extend(classes_from_pkg)

# Get root classes (classes with no parent/inheritance)
root_classes = [cls for cls in all_classes if not cls.bases]

# Write class hierarchy
hierarchy = writer.write_class_hierarchy(root_classes, all_classes)
print(hierarchy)

# Generate type-to-package mapping
mapping_writer = MappingWriter()
json_mapping = mapping_writer.write_mapping(all_packages, format="json")
md_mapping = mapping_writer.write_mapping(all_packages, format="markdown")

Data Models

The package provides comprehensive data models for representing AUTOSAR structures:

AutosarPackage

Represents a hierarchical package containing classes and subpackages.

from autosar_pdf2txt import AutosarPackage, AutosarClass

pkg = AutosarPackage(name="AUTOSAR")
pkg.add_class(AutosarClass(name="MyClass", package="M2::AUTOSAR", is_abstract=False))

AutosarClass

Represents an AUTOSAR class with attributes, inheritance, and optional ATP markers.

from autosar_pdf2txt import AutosarClass, AutosarAttribute, ATPType

cls = AutosarClass(
    name="SwComponentPrototype",
    package="M2::AUTOSAR::Components",
    is_abstract=False,
    atp_type=ATPType.ATP_MIXED_STRING,
    attributes=[
        AutosarAttribute(
            name="shortName",
            type="String",
            mult="1",
            kind=AttributeKind.ATTRIBUTE
        )
    ]
)

AutosarEnumeration

Represents an AUTOSAR enumeration type with literals.

from autosar_pdf2txt import AutosarEnumeration, AutosarEnumLiteral

enum = AutosarEnumeration(
    name="Category",
    package="M2::AUTOSAR"
)
enum.enumeration_literals = [
    AutosarEnumLiteral(name="VALUE1", index=0, description="First value"),
    AutosarEnumLiteral(name="VALUE2", index=1, description="Second value"),
]

AutosarDoc

Represents a complete AUTOSAR document with packages and root classes.

from autosar_pdf2txt import AutosarDoc

doc = AutosarDoc(packages=[pkg1, pkg2], root_classes=[root_cls1, root_cls2])

# Query packages and classes
pkg = doc.get_package("AUTOSAR")
cls = doc.get_root_class("SwComponentPrototype")

Examples

The repository includes sample AUTOSAR specification PDFs in the examples/pdf/ directory:

• AUTOSAR_CP_TPS_BSWModuleDescriptionTemplate.pdf
• AUTOSAR_CP_TPS_DiagnosticExtractTemplate.pdf
• AUTOSAR_CP_TPS_ECUConfiguration.pdf
• AUTOSAR_CP_TPS_ECUResourceTemplate.pdf
• AUTOSAR_CP_TPS_SoftwareComponentTemplate.pdf
• AUTOSAR_CP_TPS_SystemTemplate.pdf
• AUTOSAR_CP_TPS_TimingExtensions.pdf

Example: Basic Extraction

# Extract a single AUTOSAR template
autosar-extract examples/pdf/AUTOSAR_CP_TPS_ECUConfiguration.pdf

# Extract all AUTOSAR templates from the examples directory
autosar-extract examples/pdf/

# Save output to a markdown file
autosar-extract examples/pdf/ -o autosar_templates.md

# Extract specific templates
autosar-extract \
  examples/pdf/AUTOSAR_CP_TPS_SystemTemplate.pdf \
  examples/pdf/AUTOSAR_CP_TPS_SoftwareComponentTemplate.pdf \
  -o system_and_component.md

# Extract with verbose output to see processing details
autosar-extract examples/pdf/AUTOSAR_CP_TPS_ECUConfiguration.pdf -v

Example: Generate Class Hierarchy

Create a separate file showing the class inheritance hierarchy:

# Extract Software Component Template with class hierarchy
autosar-extract examples/pdf/AUTOSAR_CP_TPS_SoftwareComponentTemplate.pdf -o autosar_model.md --include-class-hierarchy 

# This creates two files:
# - software_components.md (package hierarchy)
# - software_components-hierarchy.md (class inheritance tree)

The class hierarchy file shows:

## Class Hierarchy

* SwComponentPrototype
  * RequiredSwComponentPrototype
* SwcInternalBehavior
  * RunnableEntity
    * ClientServerOperation
  * TriggerEntity

Example: Generate Individual Class Files

Generate separate markdown files for each AUTOSAR class:

# Extract and create individual class files
autosar-extract examples/pdf/AUTOSAR_CP_TPS_ECUConfiguration.pdf \
  --include-class-details \
  -o data/autosar_models.md

# This creates:
# - data/autosar_models.md (consolidated output)
# - data/autosar_models/classes/<PackageName>/<ClassName>.md (individual files)

Example: Combined Output

Generate all outputs in a single run:

autosar-extract examples/pdf/ -o autosar_complete.json --include-class-hierarchy --include-class-details

Output:

Parsing: examples/pdf/AUTOSAR_CP_TPS_SoftwareComponentTemplate.pdf
Found 15 packages
Collected 234 classes from 15 packages
Generated class hierarchy for 45 root classes
Writing to: autosar_complete.md
Class hierarchy written to: autosar_complete-hierarchy.md
Writing class files to: autosar_complete/classes/

**Common auto-corrections** include:
- Attribute name case corrections (e.g., `Shortname` → `shortName`)
- Type name corrections (e.g., `SwComponent` → `SwComponentType`)
### Example: Generate Type-to-Package Mapping

Generate a simple mapping of all types to their package paths:

```bash
# Generate JSON mapping
autosar-extract examples/pdf/AUTOSAR_CP_TPS_SoftwareComponentTemplate.pdf \
  -o mapping.json --generate-mapping

# Generate Markdown table mapping
autosar-extract examples/pdf/AUTOSAR_CP_TPS_SoftwareComponentTemplate.pdf \
  -o mapping.md --generate-mapping

JSON Output Format (mapping.json):

{
  "types": [
    {
      "name": "SwComponentPrototype",
      "type": "Class",
      "package_path": "M2::AUTOSAR::Components"
    },
    {
      "name": "Category",
      "type": "Enumeration",
      "package_path": "M2::AUTOSAR::DataTypes"
    },
    {
      "name": "LimitValue",
      "type": "Primitive",
      "package_path": "M2::AUTOSAR::DataTypes"
    }
  ]
}

Markdown Output Format (mapping.md):

# Type to Package Mapping

| Name | Type | Package Path |
|------|------|--------------|
| SwComponentPrototype | Class | M2::AUTOSAR::Components |
| RequiredSwComponentPrototype | Class | M2::AUTOSAR::Components |
| Category | Enumeration | M2::AUTOSAR::DataTypes |
| LimitValue | Primitive | M2::AUTOSAR::DataTypes |

Python API for Mapping Generation:

from autosar_pdf2txt import PdfParser, MappingWriter

# Parse PDFs
parser = PdfParser()
doc = parser.parse_pdfs(["examples/pdf/AUTOSAR_CP_TPS_SoftwareComponentTemplate.pdf"])

# Generate mapping
writer = MappingWriter()

# JSON format
json_mapping = writer.write_mapping(doc.packages, format="json")
print(json_mapping)

# Markdown format
md_mapping = writer.write_mapping(doc.packages, format="markdown")
print(md_mapping)

Alternative import (if you prefer importing from the writer submodule):

from autosar_pdf2txt import PdfParser
from autosar_pdf2txt.writer import MappingWriter

Output Format

Package Hierarchy Output

The package hierarchy uses asterisk-based markdown formatting with indentation:

* AUTOSAR
  * DataTypes
    * String
  * Components
    * SwComponentPrototype (abstract)
    * RequiredSwComponentPrototype

• Packages: indented 2 spaces per level
• Classes: indented 1 level deeper than their parent package
• Abstract classes marked with (abstract) suffix

Class Hierarchy Output

The class hierarchy shows inheritance relationships from root classes:

## Class Hierarchy

* RootClass1 (abstract)
  * ChildClass1
    * GrandchildClass
  * ChildClass2
* RootClass2
  * ChildClass3

• Root classes (no parent) at top level
• Child classes indented 2 spaces per inheritance level
• Circular references detected and marked with "(cycle detected)"

JSON Output Format

The tool also supports JSON output for machine-readable data extraction and programmatic processing:

# Explicit format selection
autosar-extract input.pdf -o output.json --format json
autosar-extract input.pdf -o output.md --format markdown

# Automatic format inference from file extension
autosar-extract input.pdf -o output.json    # Creates JSON output
autosar-extract input.pdf -o output.md      # Creates markdown output
autosar-extract input.pdf -o output         # Default: markdown

JSON File Structure

JSON output creates a multi-file structure with separate files for different entity types:

output/
├── index.json                              # Root index with overview
└── packages/
    ├── M2.json                              # Package metadata

    ├── M2.enums.json                        # All enumerations in M2
    ├── M2_AUTOSAR.json                      # Subpackage metadata
    ├── M2_AUTOSAR.classes.json              # Classes in subpackage
    └── ...
