go-themes

Terminal color schemes from iTerm2-Color-Schemes packaged as Go structs. Includes 450+ themes like Dracula, Nord, Gruvbox, Monokai, etc.

Themes are generated at build time and compiled into your binary, so there's no runtime parsing overhead. Colors are provided as hex strings that work directly with Lipgloss and most TUI libraries.

Installation

go get go.withmatt.com/themes

Usage

theme, err := themes.GetTheme("Dracula")
if err != nil {
    log.Fatal(err)
}

fmt.Println(theme.Foreground)  // #f8f8f2
fmt.Println(theme.Background)  // #282a36

With Lipgloss:

theme, _ := themes.GetTheme("Nord")

style := lipgloss.NewStyle().
    Foreground(lipgloss.Color(theme.Foreground)).
    Background(lipgloss.Color(theme.Background))

fmt.Println(style.Render("Hello, Nord!"))

List all themes:

for _, name := range themes.ListThemes() {
    fmt.Println(name)
}

API

// Get a theme by name (case-insensitive)
func GetTheme(name string) (*Theme, error)

// List all theme names
func ListThemes() []string

// Get all themes as a map
func GetAllThemes() map[string]*Theme

The Theme struct contains Foreground, Background, Cursor, and all 16 ANSI colors (Black, Red, Green, Yellow, Blue, Magenta, Cyan, White, and their Bright* variants). All colors are lowercase hex strings like #282a36.

Updating

To regenerate themes from the latest upstream:

go generate ./...

This clones iTerm2-Color-Schemes, parses the JSON files, and generates generated_themes.go.
