Usage

Command Line Interface

The autosar-extract command provides a simple interface for extracting AUTOSAR models from PDF files.

# Extract from single PDF and print to stdout
autosar-extract path/to/file.pdf

# Extract from multiple PDFs
autosar-extract path/to/file1.pdf path/to/file2.pdf path/to/file3.pdf

# Extract from directory (processes all PDFs in directory)
autosar-extract path/to/directory

# Extract from multiple directories and files
autosar-extract path/to/dir1 path/to/file.pdf path/to/dir2

# Extract and save to file
autosar-extract path/to/file.pdf -o output.md

# Generate class inheritance hierarchy in separate file
autosar-extract path/to/file.pdf -o output.md --include-class-hierarchy
# Creates: output.md (package hierarchy) and output-hierarchy.md (class inheritance)

# Create individual markdown files for each class
autosar-extract path/to/file.pdf -o output.md --include-class-details
# Creates: output.md and output/classes/<ClassName>.md files

# Enable verbose mode for detailed debug information
autosar-extract path/to/file.pdf -v

# Combine all options
autosar-extract examples/pdf/ -o data/autosar_models.md --include-class-hierarchy --include-class-details

# Write logs to a file with timestamps
autosar-extract examples/pdf/ -o output.md --log-file extraction.log

# Combine log file with verbose mode for detailed logging
autosar-extract examples/pdf/ -o output.md --log-file extraction.log -v

CLI Options

• pdf_files: Path(s) to PDF file(s) or director(y/ies) containing PDFs to parse
• -o OUTPUT, --output OUTPUT: Output file path (default: stdout)
• --include-class-details: Create separate markdown files for each class (requires -o)
• --include-class-hierarchy: Generate class inheritance hierarchy in a separate file (requires -o)
• --log-file LOG_FILE: Write log messages to a file with timestamps (default: console only)
• -v, --verbose: Enable verbose output mode for detailed debug information

Python API

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

from autosar_pdf2txt import PdfParser, MarkdownWriter

# 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)

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.md \
  --include-class-hierarchy \
  --include-class-details \
  -v

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/

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)"

Individual Class Files

Each class file contains detailed information:

# Package: AUTOSAR::Components

## Class: SwComponentPrototype

**Abstract**: No
**Package**: M2::AUTOSAR::Components
**Parent**: None
**ATP Type**: None

### Attributes

| Name | Type | Mult. | Kind | Note |
|------|------|-------|------|------|
| shortName | String | 1 | attribute | |
| category | Category | 0..1 | attribute | |
