frostparse

World of Warcraft 3.3.5a Combat Log Parser library, tested against several raids on Warmane's Icecrown server.

Overview

This combat log parser is written in go and provides a way to structure the COMBAT_LOG_EVENT into well-known structures.

Data Model

The CombatLogRecord struct aggregates a BaseCombatEvent, a Prefix and a Suffix. The Prefix struct is an aggregate to various prefixes, SpellAndRangePrefix, EnchantPrefix, and EnvironmentalPrefix. The member fields of the struct are pointers because some properties are not populated based on the BaseCombatEvent.EventType field of the log record.

Usage

Basic usage will provide a means to parse the combat log file into a slice of pointers to a frostparse.CombatLogRecord and you can do with the data as you please:

package main

import (   
    "log"
    "github.com/bradleybonitatibus/frostparse"
)

func main() {
    pth := "C:\\Program Files (x86)\\World of Warcraft 3.3.5a\\Logs\\WoWCombatLog.txt"
    p := frostparse.New(
        frostparse.WithLogFile(pth),
    )
    data, err := p.Parse()
    if err != nil {
        log.Fatal("failed to parse combatlog: ", err)
    }
    // handle []*frostparse.CombatLogRecord how you please
}

If you want basic summary statistics from the combat log, you can use the Collector struct:

package main

import (   
    "log"
    "github.com/bradleybonitatibus/frostparse"
)

func main() {
    pth := "C:\\Program Files (x86)\\World of Warcraft 3.3.5a\\Logs\\WoWCombatLog.txt"
    p := frostparse.New(
        frostparse.WithLogFile(pth),
    )
    data, err := p.Parse()
    if err != nil {
        log.Fatal("failed to parse combatlog: ", err)
    }
    coll := frostparse.NewCollector(
        frostparse.WithTimeresolution((time.Second*5)),
    )
    stats := coll.Run(data)
    fmt.Println("DamageBySource: ", stats.DamageBySource)
    fmt.Println("HealingBySource: ", stats.HealingBySource)
    fmt.Println("DamageTakenBySource: ", stats.DamageTakenBySource)
    fmt.Println("DamageTakenBySpell: ", stats.DamageTakenBySpell)
}
