This Go package provides commonly needed components for terminal based user interfaces.

Among these components are:

- __Input forms__ (include __input/password fields__, __drop-down selections__, __checkboxes__, and __buttons__)
- Navigable multi-color __text views__
- Sophisticated navigable __table views__
- Flexible __tree views__
- Selectable __lists__
- __Grid__, __Flexbox__ and __page layouts__
- Modal __message windows__
- An __application__ wrapper

They come with lots of customization options and can be easily extended to fit your needs.

## Installation

```bash
go get github.com/rivo/tview
```

## Hello World

This basic example creates a box titled "Hello, World!" and displays it in your terminal:

```go
package main

import (
	"github.com/rivo/tview"
)

func main() {
	box := tview.NewBox().SetBorder(true).SetTitle("Hello, world!")
	if err := tview.NewApplication().SetRoot(box, true).Run(); err != nil {
		panic(err)
	}
}
```

## Dependencies

This package is based on [github.com/gdamore/tcell](https://github.com/gdamore/tcell) (and its dependencies) as well as on [github.com/rivo/uniseg](https://github.com/rivo/uniseg).

## Versioning and Backwards-Compatibility

I try really hard to keep this project backwards compatible. Your software should not break when you upgrade `tview`. But this also means that some of its shortcomings that were present in the initial versions will remain. In addition, at least for the time being, you won't find any version tags in this repo. The newest version should be the one to upgrade to. It has all the bugfixes and latest features. Having said that, backwards compatibility may still break when:

- a new version of an imported package (most likely [`tcell`](https://github.com/gdamore/tcell)) changes in such a way that forces me to make changes in `tview` as well,
- I fix something that I consider a bug, rather than a feature, something that does not work as originally intended,
- I make changes to "internal" interfaces such as [`Primitive`](https://pkg.go.dev/github.com/rivo/tview#Primitive) or [`Focusable`](https://pkg.go.dev/github.com/rivo/tview#Focusable). You shouldn't need these interfaces unless you're writing your own primitives for `tview`. (Yes, I realize these are public interfaces. This has advantages as well as disadvantages. For the time being, it is what it is.)
