Project

About

Argo is a free and open-source project hosted on GitLab aimed at helping modern C++ developers create professional command line utilities by providing an extensive and easy-to-use header-only library for parsing of command line arguments.

The library is currently maintained by me. However, contributions in any form are most welcome!

The project is available under the MIT License. The aim is to be as permissive as possible, but when in doubt freel free to get in touch.

Bug reports and feature requests

To submit bug reports or feature requests, log an issue on the project’s issue tracker page. The project is actively maintained.

To track functional changes between library releases, please refer to the change log <https://gitlab.com/dgrine/Argo/blob/master/changelog.rst>.

Development

If you would like to contribute to the development of Argo, feel free to fork the project and send a pull request.

Requirements

The following development tools are required:

Argo itself does not have any external dependencies, however the unit-tests are written with the Catch2 test framework. There’s no need to install this as the build system takes care of fetching it locally, but it might be worth to familiarize yourself with it.

As for the coding style, the following clang-format style is used.

Test-driven development

My personal way of doing test-driven development of the library on macOS/Linux is:

$ inv library.config
$ inv library.test/debug-rtc

The first command configures the library’s build system files: CMake is invoked to generate Makefiles. By default, a debug version with address sanitization is configured. After some development, I run the unit-tests to make sure everything works as expected and that there are no regressions. Obviously, this implies that any new development has corresponding unit-tests that cover the changes and/or new features.

At the end of the process, the QC task is invoked:

$ inv qc

If this goes well, you can go ahead and submit a pull request.

Note

By default, the QC task will run platform integration tests using Docker. If for some reason you don’t want to install Docker, you may run the QC tests as inv qc --no-docker

In case you’re an authorized developer, you may use the do-it-all task:

$ inv dia

This will run the unit-tests, QC tests, platform integration tests, update the documentation, build a package and finally push and deploy your changes.

Note

When making changes, please adjust the version number accordingly. This can be done using the version task. E.g. inv version --set <major>.<minor>.<patch> or inv version --bump. To find out the current version, invoke the task without arguments: inv version
