Integrate cmd2 Into Your Project

Once installed, you will want to ensure that your project's dependencies include cmd2. Make sure your pyproject.toml or setup.py includes the following dependency

'cmd2>=2.4'

The cmd2 project uses Semantic Versioning, which means that any incompatible API changes will be release with a new major version number. The public API is documented in the API Reference.

We recommend that you follow the advice given by the Python Packaging User Guide related to install_requires. By setting an upper bound on the allowed version, you can ensure that your project does not inadvertently get installed with an incompatible future version of cmd2.

OS Considerations

If you would like to use Tab Completion, then you need a compatible version of readline installed on your operating system (OS). cmd2 forces a sane install of readline on both Windows and MacOS, but does not do so on Linux. If for some reason, you have a Linux OS that has the Editline Library (libedit) installed instead of readline, you will need to manually add a dependency on gnureadline. Make sure to include the following dependency in your pyproject.toml or setup.py:

'gnureadline'
