go-fuckerr

It is annoying that err != nil checks are everywhere in your Go code when you don't need to know about what exactly it is, and just want to propagate them to caller.

Quick Start

package main

import "github.com/jasonming/go-fuckerr/try"

func ExposedFunc() (string, error) {
    return try.Catching(func() string {
        return internalCall() // no more explicit err != nil
    })
}

func internalCall() string {
    if !satisfied {
        // just throw it
        try.Throw("illegal argument")
    }

    // r, err := somelib.Call()
    // if err != nil {
    //     return "", err
    // }

    // Simplify error check by Must
    r := try.Must(somelib.Call())

    // Or，propagate error after partial check
    r, err := somelib.Call()
    switch err {
    case somelib.ErrEmpty:
        return ""
    default:
        try.Check(err)
    }

    return r
}
