File locations

The default input logfile is in data/input.

The generated JSON will be saved to data/output.

Running the application

Using the default log file:

ruby src/app.rb

Passing a custom log file as parameter:

ruby src/app.rb path/to/log`

Running the tests

ruby src/test.rb

General Architecture

The class organization is loosely based on DDD and Clean Architecture, even though interfaces are not necessary here because Ruby has duck typing.

The general idea of the script is to determine all the players that joined a match using their client IDs and keep track of all deaths that happened.

When requested, the array of death events is reduced to a single state to determine the number of kills by each player or each type of death.

app.rb

Entry-point for executing this application.

domain

Classes that represents the game structure and contains the rules for kills and players.

Classes in this layer are agnostic to the logfile or anything in the infra or view layer. They can be populated from any datasource like databases, REST APIs, tests or the logfile.

The class Match is the aggregate root for the entities represented in the domain.

infra

Classes that interfaces with external systems like the logfile or a database.

Classes in this layer knows the domain classes and are responsible for creating the domain instances using aggregate roots.

view

Classes that are responsible for formatting and presenting data, like converting a domain entity to JSON, XML or HTML.

Details about the reports

Report - Kills by player

• The keys in the JSON are sorted from the player with most kills to the one with less kills.

• All players that connected to the match are included in the response, even if the player did not kill and was not killed by anyone.

• The score of a player can be negative instead of stopping at zero if it was killed more times by the World than his kill count.

• Deaths by suicide are not counted.

Report - Kills by type

• The keys in the JSON are sorted from the type with most kills to the one with less kills.

• All types are included in the report, even the ones that did not happen in the match.

• Deaths by suicide are not counted.

Example of death by suicide:

8:13 Kill: 7 7 7: Assasinu Credi killed Assasinu Credi by MOD_ROCKET_SPLASH
