Is OfficeCLI Open Source? A Complete Guide to Contributing

OfficeCLI is open-source software released under the MIT license, allowing anyone to use, modify, and distribute the code, with contributions managed through GitHub pull requests following the workflow outlined in CONTRIBUTING.md.

OfficeCLI is an open-source command-line interface that enables developers to create, edit, and manage Office documents programmatically. Hosted publicly on GitHub under the permissive MIT license, the project welcomes community contributions to its Core CLI, multi-language SDK, and documentation. Understanding the repository structure and contribution workflow is essential for developers looking to add features or fix bugs.

License and Open Source Status

The project is explicitly open source, governed by the MIT license found in the repository root at LICENSE. This permissive license grants users the right to use, copy, modify, merge, publish, distribute, sublicense, and sell copies of the software. As an open-source project, OfficeCLI accepts contributions from individual developers and organizations without requiring a contributor license agreement (CLA).

Repository Architecture

The codebase is organized into distinct logical layers, each with specific responsibilities and entry points:

• Core CLI: The C# entry point that parses commands and invokes SDK functions. Key file: src/officecli/officecli.csproj.

• SDK: Language-agnostic APIs for C#, TypeScript, and Python that interact with Office file formats. Key file: sdk/node/index.d.ts.

• Examples: Ready-to-run scripts demonstrating CLI capabilities. Key files: examples/word/textbox.sh and examples/word/textbox.py.

• Build & Install: Cross-platform compilation and installation helpers. Key files: install.sh (macOS/Linux) and install.ps1 (Windows).

• Documentation: Project guidelines and policies. Key files: README.md, CONTRIBUTING.md, and SECURITY.md.

How to Contribute to OfficeCLI

Setting Up Your Development Environment

Begin by forking the repository on GitHub, then clone your fork locally. Run the platform-specific installation script to compile the CLI and verify your environment:

# Unix/Linux/macOS

./install.sh

# Windows PowerShell

.\install.ps1

After installation, explore the examples/ directory to understand the SDK's public API and CLI command patterns. Run the example scripts to validate your setup:

./examples/word/textbox.sh input.docx output.docx "Hello, OfficeCLI!"

This script internally calls officecli word textbox --text "Hello, OfficeCLI!" input.docx output.docx, demonstrating how the CLI maps high-level actions to SDK calls.

Contribution Workflow

Follow these steps to submit changes to the OfficeCLI open-source project:

1. Read the contribution guide at CONTRIBUTING.md, which outlines coding conventions, commit message style, and the pull-request process.
2. Create a feature branch for your bug fix or enhancement.
3. Maintain code consistency with existing patterns. The Core CLI follows standard .NET conventions, while the SDK adheres to Node/TypeScript linting rules.
4. Add or update tests to cover your modifications.
5. Run CI workflows locally by executing the checks defined in .github/workflows/skill-parity.yml and .github/workflows/sdk-smoke.yml to ensure your changes pass all validation gates.
6. Open a Pull Request against the main branch, linking any relevant issue with a clear description of changes.

Code Quality Standards

Contributions must maintain cross-platform compatibility. CLI scripts are written in Bash or PowerShell to support macOS, Linux, and Windows environments. C# code in src/officecli/ must follow .NET naming conventions and project structure, while TypeScript definitions in sdk/node/ require strict typing alignment with index.d.ts. Assets for documentation are stored in assets/ and referenced via relative paths.

Practical Code Examples

When contributing new features, reference the existing Python SDK patterns. Below is an example of the object-oriented API structure found in examples/word/textbox.py:

from officecli import WordDocument

doc = WordDocument("input.docx")
doc.add_table(rows=3, cols=4, style="LightGrid")
doc.save("output.docx")

This demonstrates how the SDK mirrors CLI capabilities while allowing programmatic use. When adding features, ensure parity between the CLI arguments (handled in src/officecli/) and the SDK implementations.

Summary

• OfficeCLI is open source under the MIT license, located in the LICENSE file at the repository root.

• Contributions require forking the repository, running install.sh or install.ps1, and following the workflow in CONTRIBUTING.md.

• Architecture spans C# Core CLI, multi-language SDK (TypeScript/C#/Python), and example scripts in examples/.

• Quality gates include local execution of CI workflows (skill-parity.yml, sdk-smoke.yml) and adherence to .NET/TypeScript conventions.

• Cross-platform support is mandatory; all installation and build scripts must function on macOS, Linux, and Windows.

Frequently Asked Questions

What license is OfficeCLI released under?

OfficeCLI is released under the MIT license, as specified in the LICENSE file. This permissive open-source license allows commercial use, modification, distribution, and private use with minimal restrictions, requiring only that the original copyright notice and license terms be included with any substantial portions of the code.

Do I need to sign a contributor license agreement (CLA) to contribute?

No, the project does not require a Contributor License Agreement (CLA). Under the MIT license terms, contributors retain copyright to their submissions while granting the project the rights to use and distribute the code. Simply follow the guidelines in CONTRIBUTING.md and submit your pull request through GitHub.

What programming languages are used in OfficeCLI?

The project uses C# for the Core CLI (src/officecli/officecli.csproj), TypeScript/JavaScript for the Node SDK (sdk/node/index.d.ts), Python for alternative SDK bindings, and Bash/PowerShell for build and installation scripts. Contributors should be familiar with .NET conventions for CLI changes and Node.js patterns for SDK modifications.

How do I test my changes before submitting a pull request?

Run the platform-specific install script to compile the project locally, then execute the relevant example scripts (such as examples/word/textbox.sh) to verify functionality. Additionally, run the continuous integration checks locally using the workflow files in .github/workflows/skill-parity.yml and .github/workflows/sdk-smoke.yml to ensure your changes do not break existing functionality across supported platforms.
