onism-up/go-tml-core

Core part of terminal rendering library based on go language

go-tml-core

Language

简体中文

Demonstration

Peculiarity

• Low memory and resource usage
• Asynchronous graphics renderer
• Highly scalable
• Componentized components can be used
• More complete event support
• Window adaptive, position dynamic calculation

Ensure that the target terminal supports VT100 before use,The output of the program is based on VT100.

Start

Here shows part of the code, he can not run correctly, if you want to see all the code, please view or debug in the demo

package main

import "github.com/onism-up/go-tml-core/tml"

func main(){
    tml.Start(100, true) //initialize
    
    style, _ := tml.Body.GetStyle()
    style.BackGroundColor = tml.YellowBackGroundColor
	tml.Body.SetStyle(style) //root node style Settings
    
    button1 := button(router1(), "MoveBox", tml.CanvasPosition{
    X: 10,
    }, tml.CanvasPositionType{Center: tml.PositionY}) //Create component
    
    button2 := button(/* Some information is omitted */)
    
    button3 := button(/* Some information is omitted */)
    
    buttonBase := []tml.Node{button1, button2, button3}
    
    index := -1
	
    tml.Body.AddEventListener(tml.OnKeyBord, func(node tml.Node, _ tml.Node) { //Listening event
        keyBord, _ := node.GetKeyBord()
        
        switch keyBord.Key {
        case tml.KeyArrowLeft:
            if index > 0 {
            index--
            }
            break   
        case tml.KeyArrowRight:
            if index < 2 {
            index++
            }
            break
        case tml.KeyEnter: //If transfer is selected, the transferred node will continue to listen for keyboard events
            if index <= 2 && index >= 0 {
                tml.Select(buttonBase[index])
            }
        }
        
        for buttonIndex, buttonNode := range buttonBase {
            buttonStyle, _ := buttonNode.GetStyle()
            
            if buttonIndex == index {
                buttonStyle.BackGroundColor = tml.PurpleBackGroundColor
                buttonStyle.BorderType = tml.ContinuousLine
                buttonStyle.BorderColor = tml.WhiteColor
            } else {
                buttonStyle.BackGroundColor = tml.BlueBackGroundColor
                buttonStyle.BorderType = tml.None
            }
            
            buttonNode.SetStyle(buttonStyle)
        }})
	//Insert all nodes into the top-level node to display
    tml.Body.Insert(title("<< demo: check left or right move light block >>"), button1, button2, button3)
	
    for true { //Prevent program termination
		
    }
}

Customize a Node or component

At present, there is no wrapped component in tml, only a base component and a base node, if you want to create a new rendering node, you can try to create a new file in tml, and then add a node to the renderer, if you want to encapsulate a new component, you can try based on the base node, if you feel that your component or rendering node is good, You can try to push it to the project
