## gotui：现代 Go 终端仪表盘 gotui 是一个完全可定制的、跨平台的终端仪表盘和 Go 语言的组件库，源自 termui 并受到 ratatui 的启发。由 Carsen Klock 开发，它专为 2025 年及以后设计，具有显著的升级，包括 TrueColor 支持、改进的性能和现代终端事件处理。它提供了一套丰富的组件：仪表盘、各种图表（条形图、饼图、雷达图、树状图、漏斗图、火花线、折线图）、地图，以及新增的线性仪表盘、滚动条和像素级 Logo 渲染器。性能是关键重点，优化的渲染可实现高达 3000 FPS，并最大限度地减少内存分配。布局选项包括响应式网格和选项卡，以及日历和表格等交互元素。样式高度灵活，支持圆角边框、全 RGB 色彩和丰富的文本解析。 gotui 与 iTerm2 和 Kitty 等流行的终端兼容，并利用原生 tcell 实现核心功能。安装过程简化，使用 Go 的依赖管理 – 无需显式 `go get`。

## Gotui：一个新的Go终端仪表盘库一个名为 **Gotui** 的新Go库已经发布，它是之前未维护的`termui`的现代分支。由carsenk开发，Gotui旨在提供一个简单的API来构建终端仪表盘和工具，但具有显著的改进。主要特性包括通过`tcell`支持TrueColor和鼠标，正确的尺寸调整处理，以及各种新的小部件，如图表、仪表和甚至世界地图。还包括圆角和折叠边框等视觉增强，以及经过重新设计的渲染器以提高性能。开发者正在积极寻求反馈，以完善Gotui以供生产使用。早期评论者建议在README中添加屏幕截图以提高可用性，甚至为每种图表类型提供专门的示例。你可以在GitHub上找到该项目：[github.com/metaspartan](https://github.com/metaspartan)。

gotui is a cross-platform and fully-customizable terminal dashboard and widget library built on top of tcell. It is a modern fork of termui, inspired by ratatui and written purely in Go by Carsen Klock.

This is a modern fork of termui for 2025, heavily upgraded to support TrueColor, modern terminal events, better performance, and new layouts.

gotui is compatible with Go 1.24+.

Backend: Native tcell support for TrueColor (24-bit RGB), mouse events, and resize handling.
Gauges: Progress bars and gauges.
Charts:
- BarChart: Stacked and standard bar charts.
- PieChart: Pie and Donut charts.
- RadarChart: Spider/Radar charts.
- TreeMap: Hierarchical data visualization.
- FunnelChart: Process flow/conversion charts.
- Sparkline: Mini sparklines.
- Plot: Line, Scatter, and Braille-mode charts.
Maps:
- World Map: High-resolution world map example using the generic Canvas widget (see _examples/canvas.go).
New Widgets:
- LineGauge: Thin, character-based progress bar with alignment options (Block, Dots, custom runic styles).
- Scrollbar: Ratatui-compatible scrollbars (Vertical/Horizontal) with mouse and keyboard support.
- Logo: Pixel-perfect block-style logo renderer.
Performance:
- Optimized Rendering: Buffer uses flat slices for O(1) access, providing 2-3x speedup.
- Zero Allocations: Drawing loops minimized for high-fps scenes (~3000 FPS potential).
Layout:
- Grid: Responsive grid layout.
- Tabs: Tabbed navigation.
- Interactive: Calendar, Tables, Input, TextArea.
Styling:
- Rounded Borders: Optional rounded corners for blocks.
- Full RGB Color support.
- Border titles (Top and Bottom) with alignment (Left, Center, Right).
- Rich styling parser for text.
- Collapsed Borders: Support for merging adjacent block borders using BorderCollapse.
Compatibility: Works with modern terminals (iTerm2, Kitty, Alacritty, Ghostty).

It is not necessary to go get gotui, since Go will automatically manage any imported dependencies for you.

go get github.com/metaspartan/gotui/v4

package main

import (
	"log"

	ui "github.com/metaspartan/gotui/v4"
	"github.com/metaspartan/gotui/v4/widgets"
)

func main() {
	if err := ui.Init(); err != nil {
		log.Fatalf("failed to initialize gotui: %v", err)
	}
	defer ui.Close()

	p := widgets.NewParagraph()
	p.Text = "Hello World!"
	p.SetRect(0, 0, 25, 5)

	ui.Render(p)

	for e := range ui.PollEvents() {
		if e.Type == ui.KeyboardEvent {
			break
		}
	}
}

Run an example with go run _examples/{example}.go or run each example consecutively with make run-examples.
