Playground

Small terminal games and concurrency examples in Go, Python, and Rust.

Run an example

Run each command from the directory in the table.

Example	Directory	Command
Dodge game in Go	games/dodge/go	go run .
Dodge game in Python	games/dodge/python	python3 main.py
Dodge game in Rust	games/dodge/rust	cargo run --locked
Concurrent jobs in Go	concurrency/go	go run .
Concurrent jobs in Rust	concurrency/rust	cargo run --locked

The games need an interactive terminal. Move with the left and right arrow keys. Press q or Escape to quit. The Go and Python games then wait for another key.

See the Rust game screenshot.

Use Go 1.23.5 or newer, Rust with Cargo, and Python 3 with curses support. The concurrency examples finish when every job reaches at least 10.

Verify the examples

Run these commands from the repository root:

python3 scripts/verify-imports.py
python3 scripts/smoke.py

The import check compares each directory with its original Git tree and checks that the original commits and branch tags are present. The smoke check builds the compiled examples, checks both concurrency results, and starts and quits all three games in headless terminals on Linux. Build outputs go to a temporary directory.

Original histories

This repository combines five former repositories owned by vimkim:

• dodge-game-go
• dodge-game-py
• dodge-game-rs
• concurrent-job-demo-rust
• concurrent-jobs-demo-go

The import keeps their original files and commit IDs. Each source branch tip has a tag named source/<repository>/<branch>. These tags retain the original root layout. imports.json records the source commits, trees, and paths.

For example, inspect the original Go game history with:

git log source/dodge-game-go/chatgpt
