Flora

Flora reads configuration from files, environment variables, and command-line flags, merges them in a predictable order, and gives you typed access to the result. It has no third-party dependencies and a stable public API.

Why Flora

• Zero dependencies. The core module imports only the standard library.
• Predictable merging. Sources are layered in a documented order; the winner of any key is always explainable.
• Typed access. Decode into structs with tags, or read individual keys with typed getters.
• Formats out of the box. JSON, TOML, and a small INI dialect, with a pluggable decoder interface for the rest.
• Quiet by default. No global state, no init-time magic, no network access.

A quick taste

package main

import "github.com/flora-ling/flora"

type Config struct {
    Addr    string `flora:"addr"`
    Timeout int    `flora:"timeout"`
}

func main() {
    var cfg Config
    must(flora.Load(&cfg,
        flora.File("config.toml"),
        flora.Env("APP_"),
    ))
}
