stack2struct

stack2struct parses raw golang stack traces ([]byte) to a slice of well formated structs.

Getting Started

Installation

  $ go get github.com/kaeuferportal/stack2struct

Usage

package main

import (
  "encoding/json"
  "fmt"
  "runtime"

  "github.com/kaeuferportal/stack2struct"
)

type stackTraceElement struct {
  LineNumber int    `json:"lineNumber"`
  ClassName  string `json:"className"`
  FileName   string `json:"fileName"`
  MethodName string `json:"methodName"`
}

type stackTrace []stackTraceElement

func (s *stackTrace) AddEntry(lineNumber int, packageName, fileName, methodName string) {
  *s = append(*s, stackTraceElement{lineNumber, packageName, fileName, methodName})
}

func main() {

  rawStackTrace := make([]byte, 1<<16)
  rawStackTrace = rawStackTrace[:runtime.Stack(rawStackTrace, false)]

  stack := make(stackTrace, 0, 0)
  stack2struct.Parse(rawStackTrace, &stack)

  enc, _ := json.MarshalIndent(stack, "", "\t")
  fmt.Println(string(enc))

}

should print

[
  {
    "lineNumber": 27,
    "className": "main",
    "fileName": "test.go",
    "methodName": "main()"
  }
]
