Termdash is a cross-platform customizable terminal based dashboard.
The feature set is inspired by the gizak/termui project, which in turn was inspired by yaronn/blessed-contrib.
This rewrite focuses on code readability, maintainability and testability, see the design goals. It aims to achieve the following requirements. See the high-level design for more details.
Public API and status
The public API surface is documented in the
Private packages can be identified by the presence of the /internal/
directory in their import path. Stability of the private packages isn't
guaranteed and changes won't be backward compatible.
There might still be breaking changes to the public API, at least until the
project reaches version 1.0.0.
