glyph

Declarative terminal UI framework for Go. useglyph.sh

VBox.Border(BorderDouble).Title("SYS").FitContent()(
    If(&online).
        Then(Text("● ONLINE")).
        Else(Text("● OFFLINE").FG(Red)),
    HRule(),
    Leader("CPU", &cpu),
    Leader("MEM", &mem),
    Sparkline(&history),
)

• Declarative. UI is a tree of typed values; glyph compiles the layout and renders each frame.
• Flex layout. VBox/HBox with grow, gap, borders, and cascading styles.
• Components. Lists, tables, inputs, fuzzy filtering, sparklines, tabs, tree views, overlays, vim bindings, theming.
• Your data, directly. Pass a pointer; glyph reads the current value every update.

Run any of the included demos to see the framework in action:

Go 1.25 or later. macOS and Linux only; Windows support is on the roadmap.

go get github.com/kungfusheep/glyph

func main() {
    app := NewApp()
    app.SetView(Text("Hello, terminal!")).Run()
}

The core is stable and has been used to build real things. The API covers the full range of what a TUI framework needs. Pre-1.0 because the surface is still under evaluation; parts of it can be better still, and 1.0 means committing to it.
