picker

===

一个基于 [yaegi](https://github.com/traefik/yaegi) 的轻量插件容器，支持在运行时按配置加载并执行 Go 函数。

目前内置 YAML / JSON / TOML 三种配置格式。推荐在 TOML 中使用 `'''` 多行字面量存放函数体，可避免 `\n` 这类转义在解析过程中被处理。

## Quick Start

更多示例见 `picker_test.go`。

```go

package main

import (

    "context"

    "log"

    "github.com/xxxsen/picker"

)

func main() {

    pgs := &picker.Plugins{

        Plugins: []*picker.PluginConfig{

            {

                Name:     "p1",

                Function: `func(ctx context.Context) {fmt.Println("hello world")}`,

            },

            {

                Name:     "p2",

                Import:   []string{"fmt"},

                Function: `func(ctx context.Context) {fmt.Println("hello again")}`,

            },

            {

                Name:   "p3",

                Define: "a := 3.14",

                Function: `func(ctx context.Context) {fmt.Printf("value a:%f\n", a)}`,

            },

        },

    }

    pk, err := picker.Load[func(context.Context)](pgs)

    if err != nil {

        log.Fatalf("load plugins failed: %v", err)

    }

    for _, name := range pk.List() {

        fn, _ := pk.Get(name)

        fn(context.Background())

    }

}

```

> 提示：泛型参数决定了插件函数签名，确保配置中的函数类型与之匹配即可；参数数量、类型都可以自行定义。
