Thanks for considering contributing to Logtalk. All contributions are most welcome, including code patches, bug reports, documentation fixes, feature suggestions, portability improvements, new libraries, new examples, and improved support for text editors and IDEs. No contribution is too small. The ACKNOWLEDGMENTS.md file lists past contributions and their authors. Looking forward to see your name there.

How to make a contribution

Bur bug reports and suggestions, create a ticket in our issue tracker at:


If you prefer to discuss your contribution first with other developers, you can join us for live discussion at our chat room:


In alternative, you can also join our discussion forums at:


In the case of code contributions, follow the coding guidelines described at:


Submit your code contribution preferably by forking Logtalk, working on a topic branch, and creating a pull request. If you're not familiar with pull request based contributions to open source projects, see e.g.


When contributing compiler, runtime, or library enhancements, ensure there are no regressions by testing your contribution. For details, see:


Ideally, new code should come with a comprehensive test set. For writing tests, see our unit testing framework documentation at:


Please note that portability is main Logtalk feature. As a general rule, new code should depend only on standard or de factor standard features available from the supported backend Prolog systems. But contributions that enhance the integration with a particular backend Prolog system are also sought as long they don't break support for other systems.

Integrating your contribution

Major code and documentation contributions may require the contributor to sign and submit a contributor license agreement and should be made available under the Logtalk license without any additional terms or conditions. Contributions using other licensing terms may also be distributed with Logtalk with the understanding that the terms of their use depends solely on the authors chosen licensing terms and may require a separate, independent, agreement between users and authors.
