Experimenting with marcusolsson/tui-go as a search/list combobox

README.md

So this is basically me taking a couple of examples from https://github.com/marcusolsson/tui-go/tree/master/example (mostly just color and http) and experimenting with how they work.

lucytest.go

package main

import (
	"log"
	"strings"

	"github.com/marcusolsson/tui-go"
)

var (
	accountsList = []string{
		"team_badger",
		"superteam",
		"my_first_account",
		"hal_spacejock",
		"super_secret_facebook_competitor",
		"jeff",
	}
)

func main() {
	list := tui.NewList()
	for _, account := range accountsList {
		list.AddItems(account)
	}

	respBody := tui.NewVBox(list)
	respBody.SetTitle("Accounts")
	respBody.SetBorder(true)

	resp := tui.NewVBox(respBody)
	resp.SetSizePolicy(tui.Expanding, tui.Preferred)

	browser := tui.NewHBox(resp)
	browser.SetSizePolicy(tui.Preferred, tui.Expanding)

	urlEntry := tui.NewEntry()
	urlEntry.SetText("")
	urlEntry.OnChanged(func(e *tui.Entry) {
		//respBodyLbl.SetText(e.Text())

		selected := ""
		// TODO: get selected item
		if list.Selected() != -1 {
			selected = list.SelectedItem()
		}

		// Clear out list
		list.RemoveItems()

		itemsAdded := 0

		// Re-add items
		for _, account := range accountsList {
			if strings.Contains(account, e.Text()) {
				list.AddItems(account)
				itemsAdded = itemsAdded + 1

				if account == selected {
					list.Select(itemsAdded - 1)
				}
			}
		}

		// if we only have one item, select it
		if itemsAdded == 1 {
			list.Select(0)
		}

	})
	urlEntry.OnSubmit(func(e *tui.Entry) {
		// TODO: iff list has a single element, use it
	})

	urlBox := tui.NewHBox(urlEntry)
	urlBox.SetTitle("Search Accounts")
	urlBox.SetBorder(true)

	tui.DefaultFocusChain.Set(urlEntry, list)
	root := tui.NewVBox(urlBox, browser)
	// Add a list to this

	theme := tui.NewTheme()
	theme.SetStyle("box.focused.border", tui.Style{Fg: tui.ColorYellow, Bg: tui.ColorDefault})
	normal := tui.Style{Bg: tui.ColorBlack, Fg: tui.ColorWhite}
	highlight := tui.Style{Bg: tui.ColorWhite, Fg: tui.ColorBlack}
	theme.SetStyle("list.item", normal)
	theme.SetStyle("list.item.selected", highlight)

	ui, err := tui.New(root)
	if err != nil {
		log.Fatal(err)
	}

	ui.SetTheme(theme)
	ui.SetKeybinding("Esc", func() { ui.Quit() })

	if err := ui.Run(); err != nil {
		log.Fatal(err)
	}
}
