|
|
The feature set is inspired by the
|
|
[gizak/termui](http://github.com/gizak/termui) project, which in turn was
|
|
inspired by
|
|
[yaronn/blessed-contrib](http://github.com/yaronn/blessed-contrib).
|
|
|
|
This rewrite focuses on code readability, maintainability and testability, see
|
|
the [design goals](doc/design_goals.md). It aims to achieve the following
|
|
[requirements](doc/requirements.md). See the [high-level design](doc/hld.md)
|
|
for more details.

# Public API and status
|
|
|
|
The public API surface is documented in the
|
|
[wiki](http://github.com/mum4k/termdash/wiki).
|
|
|
|
Private packages can be identified by the presence of the **/private/**
|
|
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. Any breaking changes will be published in the
|
|
[changelog](CHANGELOG.md).
|
|
|
|
# Current feature set
|
|
|
|
- Full support for terminal window resizing throughout the infrastructure.
|
|
- Customizable layout, widget placement, borders, margins, padding, colors, etc.
|
|
- Dynamic layout changes at runtime.
|
|
- Binary tree and Grid forms of setting up the layout.
|
|
- Focusable containers and widgets.
|
|
- Processing of keyboard and mouse events.
|
|
- Periodic and event driven screen redraw.
|
|
- A library of widgets, see below.
|
|
- UTF-8 for all text elements.
|
|
- Drawing primitives (Go functions) for widget development with character and
|
|
sub-character resolution.
|
|
|
|
