# Snek
A framework for defining Battlesnake-compatible rulesets and board positions in
Elixir.
[Battlesnake][battlesnake] is an online competitive take on the classic game of
Snake. `Snek` provides some structure and tooling that developers can use
toward creating Battlesnake AIs in Elixir.
This project is not affiliated with or sponsored by Battlesnake.
## Status
This is an early work in progress, and should be considered experimental,
incomplete, and unstable until v1.0.0, following [Semantic Versioning][semver].
All notable changes will be recorded in the [changelog](CHANGELOG.md).
## Installation
Add `snek` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:snek, "~> 0.4.0"}
]
end
```
## Documentation
Documentation can be found [here at Hex.pm][hexdocs] or generated from the
source code using `mix docs`.
## Examples
The following example simulates a couple of game turns using the Standard
ruleset, for a two-player game, on a standard medium (11x11) board size.
```elixir
alias Snek.Ruleset.Standard
alias Snek.Board
# Two-player game
snake_ids = MapSet.new(["snek1", "snek2"])
# Initialize the game
{:ok, turn0} = Standard.init(Board.Size.medium, snake_ids)
# The ruleset emits `Snek.Board` states that you can analyze in various ways:
Board.empty?(turn0) # => false
Board.alive_snakes_remaining(turn0) # => 2
# Apply moves for two turns
turn1 = Standard.next(turn0, %{"snek1" => :left, "snek2" => :up})
turn2 = Standard.next(turn1, %{"snek1" => :down, "snek2" => :right})
# Is the game over? (See if you can figure out *why* the game isn't over!)
Standard.done?(turn2) # => false
```
All rulesets implement the same callbacks, so you can perform dynamic dispatch.
In the following example, the `ruleset` variable could be set to any ruleset
module name:
```elixir
ruleset = Snek.Ruleset.Solo
{:ok, turn0} = ruleset.init(Board.Size.medium, snake_ids)
```
