### Help and Support

If you have a question, issue, or suggestion regarding VisiData, please [create an issue on Github](https://github.com/saulpw/visidata/issues).

## vdtui

The core `vdtui.py` can be used to quickly create efficient terminal workflows. These have been prototyped as proof of this concept:

- [vgit](https://github.com/saulpw/vgit): a git interface
- [vsh](https://github.com/saulpw/vsh): a collection of utilities like `vping` and `vtop`.
- [vdgalcon](https://github.com/saulpw/vdgalcon): a port of the classic game [Galactic Conquest](https://www.galcon.com)

Other workflows should also be created as separate apps using vdtui. These apps can be very small and provide a lot of functionality; for example, see the included [viewtsv](bin/viewtsv).


## License

The innermost core file, `vdtui.py`, is a single-file stand-alone library that provides a solid framework for building text user interface apps. It is distributed under the MIT free software license, and freely available for inclusion in other projects.

Other VisiData components, including the main `vd` application, addons, loaders, and other code in this repository, are available for use and distribution under GPLv3.
