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, Linux, OSX)
• Sixel support
• Hints/overlays
• Built-in patched fonts for powerline
• Retina display support

Installation

MacOS

brew tap liamg/aminal
brew install aminal

Windows

Dev environment setup instructions are available there.

Prebuilt Binaries

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

Download the binary and sudo cp aminal-* /usr/local/bin/aminal && chmod +x /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 the following places, and stops when it finds one:

• $XDG_CONFIG_HOME/aminal/config.toml
• $HOME/.config/aminal/config.toml
• $HOME/.aminal.toml

Note that on Windows Aminal uses %USERPROFILE% environment variable instead of $HOME

It will write a config file to whichever of those directories exists (preferring the top of the list) the first time it runs, if one 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.
search_url = "https://www.google.com/search?q=$QUERY" # The search engine to use for the "search selected text" action. Defaults to google. Set this to your own search url using $QUERY as the keywords to replace when searching.
max_lines = 1000            # Maximum number of lines in the terminal buffer.
