Overview

A terminal based version of the 1984 game written in Go

Compatibility

This has been primarily tested on macOS Mojave with $TERM=xterm-256color. While I have been able to test on an Ubuntu VM I am sure syscalls and keyboard inputs vary depending on $TERM, which I haven't accounted for.

Windows is not currently supported.

Demo

Configuration

Options

1. -disable-ghost: Don't show the 'ghost' of the current piece
2. -disable-side: Don't show the side bar (next piece, current score, and controls)
3. -light-mode: Update colors to work for light color schemes
4. -low-contrast: Update colors to use lower contrast (updates background to white for 'light-mode', black otherwise)
5. -scheme: The control scheme to use, multiple may be specified (default: home-row)
   • all schemes can be viewed using -describe-scheme sub-command described below
6. -difficulty string: the initial difficulty (options = beginner, novice, pro, expert) (default "beginner")

Quick comparison of the color options (-light-mode enabled on bottom, -low-contrast enabled on right):

NOTE: you will also see -debug and -cpuprofile listed after running gotris -h. These were for my personal use when building this and won't be of much use to the standard user.

Sub-commands

1. -colors: Display the colors that will be used throughout the game then exit
   • useful for previewing results of the -disable-ghost, -disable-side, -light-mode, and -low-contrast options
2. -describe-scheme: Prints the specified control scheme then exits. If none specified then all available schemes are described

Some Notes

The goal of this project was to create a fully featured yet simple terminal-based version of tetris written in Go using just the standard library. This project was meant to be a learning experience which is why I chose to avoid external depencies.

Planned Features

Easier:

• Initial difficulty selection
• Width+height selection
• Other display options (opacity of ghost piece, monochrome mode, etc.)

Harder:

• Windows support
• "Hold" piece option
• Pause+resume
