go-burrito

Simple, fast, and easy to use library for handling errors.

Installation

go get github.com/Bedrock-OSS/go-burrito

Usage

package main

import (
	"fmt"
	"github.com/Bedrock-OSS/go-burrito/burrito"
)

func main() {
	burrito.PrintStackTrace = true
	err := burrito.WrappedError("This is a root error")
	err = burrito.WrapErrorf(err, "We failed to do Y and we can provide the cause")
	err = burrito.WrapErrorf(err, "We failed to do X and we can provide the cause")
	fmt.Println(err)
}

This will output:

We failed to do X and we can provide the cause
[+]: We failed to do Y and we can provide the cause
[+]: This is a root error

Setting burrito.PrintStackTrace to true will also output the stack trace for the error:

We failed to do X and we can provide the cause
   [github.com/Bedrock-OSS/go-burrito/burrito.TestReadmeExample2] main_test.go:104
[+]: We failed to do Y and we can provide the cause
   [github.com/Bedrock-OSS/go-burrito/burrito.TestReadmeExample2] main_test.go:103
[+]: This is a root error
   [github.com/Bedrock-OSS/go-burrito/burrito.TestReadmeExample2] main_test.go:102

You can also override the default setting for printing the stack trace per error by using the burrito.ForceStackTrace function.

Tags

You can also add tags to errors to help identify them. This is useful for when you want to handle errors differently based on the nature of the error.

package main

import (
	"fmt"
	"github.com/Bedrock-OSS/go-burrito/burrito"
)

const ErrNotFound = "not_found"

func main() {
	err := burrito.WrappedError("File not found")
	err.(*burrito.Error).AddTag(ErrNotFound)
	err = burrito.WrapErrorf(err, "We failed to do Y and we can provide the cause")
	err = burrito.WrapErrorf(err, "We failed to do X and we can provide the cause")
    if err.(*burrito.Error).HasTag(ErrNotFound) {
        fmt.Println("File not found")
    }
}
