This is a repo I'm putting together as the entrypoint to an apprenticeship. I haven't written much code since I moved into leadership, so this is a new way to enhance my skills and experience. It implements the minimax algorithm to make the computer theoretically unbeatable and also uses open telemetry for debugging.

Golang Installation - all other platforms

See: Golang install

Golang Installation - macOS with homebrew

brew install golang
cd <repo directory>
go get github.com/honeycombio/otel-config-go/otelconfig
go get go.opentelemetry.io/otel
go get go.opentelemetry.io/otel/attribute
go get go.opentelemetry.io/otel/codes
go get go.opentelemetry.io/otel/trace

Running the game

go run main.go

Building the executable

cd <root of the repo>
go build -o ttt main.go

This will drop an executable "ttt" in the root directory of the repo.

Running tests

go test ttt/board
go test ttt/computer

Debugging

I put all of my debugging code into open telemetry, which is setup to stream to honeycomb. Create a free account with honeycomb and then the following environment variables must be set in your terminal. Make sure you change the x-honeycomb-team to your API key.

export OTEL_SERVICE_NAME="tic-tac-toe"
export OTEL_EXPORTER_OTLP_PROTOCOL="http/protobuf"
export OTEL_EXPORTER_OTLP_ENDPOINT="https://api.honeycomb.io"
export OTEL_EXPORTER_OTLP_HEADERS="x-honeycomb-team=<YOUR_API_KEY_HERE>"

If you don't set these variables, you may get odd errors.
