Omnicon-DDSDocGen 3.1.0

DDS Document Generator

Omnicon's DDS Document Generator - API Documentation

Overview

Omnicon's DDS Document Generator (DocGen) facilitates the generation of two distinct types of documents from standard DDS type files:

• Interface documentation (ICD): A human-readable document that describes a given DDS data model.
• Comparison document: A document detailing the differences between two versions of DDS data models.

Users can leverage the DocGen through Python APIs or through dedicated GUI applications (refer to https://www.omniconsystems.com/).

Software Requirements

• Microsoft Word: This API utilizes Microsoft Word functionalities. Please ensure you have Microsoft Word installed on your system. If not, you can purchase and download it from the Official Microsoft Office website.

API Installation

pip install Omnicon_DDSDocGen

• An Omnnicon license is required to utilize the API. Please Contact [e-mail].

API Usage Example

ICD API Usage Example

The example below showcases how to generate both PDF , Docx & Html ICDs from a directory named "TypeFiles" populated with DDS .xml files and a topic mapping file "TopicNamesToTypesDefMap.xml". Both are located under the "DocGen" folder.

import os
from pathlib import Path
from Omnicon_DDSDocGen import DDSDocGen

try:
    doc_gen = DDSDocGen()

    doc_gen.generate_document(
        dds_types_files=[os.path.join(Path(os.getcwd()), "DocGen", "TypeFiles")],
        dds_topics_types_mapping=os.path.join(Path(os.getcwd()), "DocGen", "TopicNamesToTypesDefMap.xml"),
        version="v1.0",
        title="Demo ICD",
        order_alphabetically=True,
        output_file_name="DemoICD",
        output_folder="",
        output_formats=['pdf', 'docx', 'html'])

except Exception as err:
    print(err)
    exit()

TypeFiles contains DDS XML files such as ShapeType.xml (based on http://www.omg.org/spec/DDS-XML):

<?xml version="1.0" encoding="UTF-8"?>
<types xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <enum name="ShapeFillKind">
    <enumerator name="SOLID_FILL"/>
    <enumerator name="TRANSPARENT_FILL"/>
    <enumerator name="HORIZONTAL_HATCH_FILL"/>
    <enumerator name="VERTICAL_HATCH_FILL"/>
  </enum>
  <struct name= "ShapeType">
    <member name="color" stringMaxLength="128" type="string" key="true"/>
    <member name="x" type="int32"/>
    <member name="y" type="int32"/>
    <member name="shapesize" type="int32"/>
  </struct>
  <struct name= "ShapeTypeExtended" baseType="ShapeType">
    <member name="fillKind" type="nonBasic"  nonBasicTypeName= "ShapeFillKind"/>
    <member name="angle" type="float32"/>
  </struct>
</types>

TopicNamesToTypesDefMap.xml (based on http://www.omg.org/spec/DDS-XML)

<dds xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <domain_library name="Domain_Lib">
    <domain name="Domain">
      <!--Types Definition-->
      <register_type name="ShapeTypeExtended" type_ref="ShapeTypeExtended" />

      <!--Topics Definition-->
      <topic name="Square" register_type_ref="ShapeTypeExtended"/>
    </domain>
  </domain_library>
</dds>

Comparison API Usage Example

The example provided here demonstrates generating a comparison report in PDF ,Docx & Html formats from the DDS file "ShapeType.xml" and the topic mapping "TopicNamesToTypesDefMap.xml".

import os
from pathlib import Path
from Omnicon_DDSDocGen import DDSDocGen

try:
    doc_gen = DDSDocGen()

    doc_gen.generate_comparison_document(
        origin_dds_types_files=[os.path.join(Path(os.getcwd()), "DocCompare", "v1", "TypeFiles")],
        new_dds_types_files=[os.path.join(Path(os.getcwd()), "DocCompare", "v2", "TypeFiles")],
        origin_dds_topics_types_mapping=os.path.join(Path(os.getcwd()), "DocCompare", "v1", "TopicNamesToTypesDefMap.xml"),
        new_dds_topics_types_mapping=os.path.join(Path(os.getcwd()), "DocCompare", "v2", "TopicNamesToTypesDefMap.xml"),
        output_file_name="ComparisonDemo",
        title="Comparison Demo",
        origin_version="v1",
        new_version="v2",
        order_alphabetically=True,
        output_folder="",
        output_formats=['pdf', 'docx', 'html'],
        ignore_id=False,
        comparison_method="name",
        document_type="summary")

except Exception as err:
    print(err)
    exit()

API Documentation

Constructor API

Argument	Type	Description	Optional	Default value
Logging verbosity	string	Specifies the log verbosity level of choice (DEBUG, INFO, WARNING, ERROR or CRITICAL)	*	"INFO"
progress_callback_function	function	A 'pointer' to the function that updates the progress bar. [(see below)](#Progress Callback Function)	*	(A default function will print to console)

Progress Callback Function

The progress bar callback function provides the user continues updates on the document generation progress. DocGen has a default progress callback function; However, the user can provide a custom callback function of his own for the DocGen to call. The DocGen will invoke the provided function with the following information:

1. total_steps - total number of steps for the current generation process.
2. current_step - current step the generation process is currently at.
3. info - additional optional textual information regarding the current step (e.g. "saving docx")

API Return values

Both APIs return a tuple: (bool, list[str]).

• The boolean indicates whether a document was created (True) or not (False).
• The list of strings holds information regarding the creation of the file(s), such as errors detected in a certain topic/type.

The message format is as follows:

[severity level] [time] - [file format] - [message]

• Severity level: could be one of the following: 'Critical', 'Error', 'Warning', 'Info' or 'Debug'.
• Time: a time stamp, in the following format: yyyy-mm-dd hh:mm:ss.
