Go
Golang terminal emulator from scratch

Aminal - A Modern Terminal Emulator

Aminal is a modern terminal emulator for Mac/Linux implemented in Golang and utilising OpenGL.

The project is experimental at the moment, so you probably won't want to rely on Aminal as your main terminal for a while.

Ensure you have your latest graphics card drivers installed before use.

Features

• Unicode support
• OpenGL rendering
• Customisation options
• True colour support
• Support for common ANSI escape sequences a la xterm
• Scrollback buffer
• Clipboard access
• Clickable URLs
• Multi platform support (Windows coming soon...)
• Sixel support
• Hints/overlays
• Built-in patched fonts for powerline
• Retina display support

Quick Start

Installation

Prebuilt Binaries

Prebuilt binaries are available for Linux and OSX on the releases page.

Download the binary and sudo cp aminal-* /usr/local/bin/aminal.

Install with Go

go get -u github.com/liamg/aminal

Build

Dependencies

• On macOS, you need Xcode or Command Line Tools for Xcode (xcode-select --install) for required headers and libraries.
• On Ubuntu/Debian-like Linux distributions, you need libgl1-mesa-dev xorg-dev.
• On CentOS/Fedora-like Linux distributions, you need libX11-devel libXcursor-devel libXrandr-devel libXinerama-devel mesa-libGL-devel libXi-devel.

Building Locally

There are various make targets available, the most obvious being:

make test
make build
make install

As long as you have your GOBIN environment variable set up properly (and in PATH), you should be able to run aminal.

Keyboard/Mouse Shortcuts

Configuration

Aminal looks for a config file in ~/.aminal.toml, and will write one there the first time it runs, if it doesn't already exist.

You can ignore the config and use defaults by specifying --ignore-config as a CLI flag.

Config File

debug = false               # Enable debug logging to stdout. Defaults to false.
slomo = false               # Enable slow motion output mode, useful for debugging shells/terminal GUI apps etc. Defaults to false.
shell = "/bin/bash"         # The shell to run for the terminal session. Defaults to the users shell.
