chatui

chatui is a simple chat-like user interface that can be used to create chat-like user interfaces. You communicate with the UI via two channels: the OutputCh which is used to display output in the main display area and CommandCh which is used to receive commands entered by the user in the input area of the UI.

Sample usage

package main

import (
    "log"
    "strings"
    "time"

    "github.com/borud/chatui"
)

func main() {
    outputCh := make(chan string, 10)
    commandCh := make(chan string)
   
    chatui := chatui.New(chatui.Config{
        OutputCh:     outputCh,
        CommandCh:    commandCh,
        DynamicColor: false,
        BlockCtrlC:   true,
        HistorySize:  10,
    })
   
    go func() {
        for {
            outputCh <- "hey there, the time is now " + time.Now().Format("15:04:05.00")
            time.Sleep(time.Second)
        }
    }()
   
    go func() {
        for command := range commandCh {
            if strings.ToLower(command) == "/quit" {
                chatui.Stop()
            }
            outputCh <- "command was: " + command
            chatui.SetStatus("last command was: " + command)
        }
    }()
   
    go func() {
        // this is done in a goroutine because it will block if the UI is not running.
        chatui.SetStatus("type /quit to exit")
    }()
   
    err := chatui.Run()
    if err != nil {
        log.Fatal(err)
    }
}
