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.

Unicode support
OpenGL rendering
Customisation options
True colour support
Support for common ANSI escape sequences a la xterm
Scrollback buffer
Clipboard access

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.

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.
