# termui
|
|
Go terminal dashboard. Inspired by [blessed-contrib](https://github.com/yaronn/blessed-contrib), but purely in Go.
|
|
|
|
Cross-platform, easy to compile, and fully-customizable.
|
|
|
|
__Demo:__
|
|

|
|
|
## Installation
|
|
|
|
go get github.com/gizak/termui
|
|
|
|
## Usage
|
|
|
|
Each component's layout is a bit like HTML block (box model), which has border and padding.
|
|
|
|
The `Border` property can be chosen to hide or display (with its border label), when it comes to display, the label takes 1 padding space (i.e. in css: `padding: 1;`, innerHeight and innerWidth therefore shrunk by 1).
|
|
|
|
`````go
|
|
import ui "github.com/gizak/termui" // <- ui shortcut, optional
|
|
|
|
func main() {
|
|
err := ui.Init()
|
|
if err != nil {
|
|
panic(err)
|
|
}
|
|
defer ui.Close()
|
|
|
|
p := ui.NewPar(":PRESS q TO QUIT DEMO")
|
|
p.Height = 3
|
|
p.Width = 50
|
|
p.TextFgColor = ui.ColorWhite
|
|
p.Border.Label = "Text Box"
|
|
p.Border.FgColor = ui.ColorCyan
|
|
|
|
g := ui.NewGauge()
|
|
g.Percent = 50
|
|
g.Width = 50
|
|
g.Height = 3
|
|
g.Y = 11
|
|
g.Border.Label = "Gauge"
|
|
g.BarColor = ui.ColorRed
|
|
g.Border.FgColor = ui.ColorWhite
|
|
g.Border.LabelFgColor = ui.ColorCyan
|
|
|
|
ui.Render(p, g)
|
|
|
|
// event handler...
|
|
}
|
|
`````
|
|
|
|
Note that components can be overlapped (I'd rather call this a feature...), `Render(rs ...Renderer)` renders its args from left to right (i.e. each component's weight is arising from left to right).
|
|
|
|
## Themes
|
|
|
|
_All_ colors in _all_ components _can_ be changed at _any_ time, while there provides some predefined color schemes:
|
|
|
|
```go
|
|
// for now there are only two themes: default and helloworld
|
|
termui.UseTheme("helloworld")
|
|
|
|
// create components...
|
|
```
|
|
The `default ` theme's settings depend on the user's terminal color scheme, which is saying if your terminal default font color is white and background is white, it will be like:
|
|
|
|
<img src="./example/themedefault.png" alt="default" type="image/png" width="600">
|
|
|
|
The `helloworld` color scheme drops in some colors!
|
|
|
|
<img src="./example/themehelloworld.png" alt="helloworld" type="image/png" width="600">
|
|
|
|
## Widgets
