用Go写成的氦

Question

帮我检查代码。氦是我最喜欢的项目，用歌朗写的。氦是一个小型的、简单的、模块化的构造函数，带有一些预先构建的组件.

https://github.com/im-kulikov/helium

如何使用它的简单示例

package main

import (
    "context"

    "github.com/davecgh/go-spew/spew"
    "github.com/im-kulikov/helium"
    "github.com/im-kulikov/helium/grace"
    "github.com/im-kulikov/helium/logger"
    "github.com/im-kulikov/helium/module"
    "github.com/im-kulikov/helium/settings"
    "github.com/spf13/viper"
)

var mod = module.New(newApp).
    Append(
        settings.Module,
        logger.Module,
        grace.Module)

// App struct
type App struct {
    v *viper.Viper
}

func newApp(v *viper.Viper) helium.App {
    return &App{v: v}
}

// Run application
func (a App) Run(ctx context.Context) error {
    spew.Dump(a.v.AllSettings())

    return nil
}

func main() {
    h, err := helium.New(&helium.Settings{
        Prefix:       "demo",
        Name:         "demo",
        BuildTime:    "now",
        BuildVersion: "dev",
    }, mod)
    helium.Catch(err)
    helium.Catch(h.Run())
}

Answer 1

一些细节；在Run中：

// Run application
func (a App) Run(ctx context.Context) error {
    spew.Dump(a.v.AllSettings())

    return nil
}

error将始终为空。根据去。；

func Dump(a ...interface{})

Dump什么也不回。因此，您应该能够从您的签名中删除error，或者b.-在a.v上做一些明智的检查，例如，这些元素不是nil/等等。
