Features

• Terminal

  A Terminal emulator Control node.

  Supports ANSI and (some) XTerm Control Sequences which can be used to do things such as clear the screen, move the cursor, change printed text color, ring a bell, and so on. For an exhaustive list of terminal control sequences (not all of which are supported by GodotXterm) see "XTerm Control Sequences".

• PTY

  Linux and macOS only.

  Node for forking processes (e.g. bash, nodejs, python) with pseudoterminal file descriptors. Can be used with the Terminal node to get an actual shell.

  Not currently supported on Windows, but it could be in the future using ConPTY or WinPTY. See issue #25.

• Terminal Editor Plugin

  Linux and macOS only.

  Adds a panel to the Editor's bottom panel that can be used to spawn terminals in the editor. Similar to VSCode's integrated terminal and IntelliJ's embedded terminal.

• Asciicast Import Plugin

  Adds support for importing asciinema v2 .cast files as animations that can be played by an AnimationPlayer that is a child of a Terminal node. Example .cast files can be downloaded from the asciinema website.

• Xresources Import Plugin

  Adds support for importing color schemes from .xrdb or .Xresources files. Example xresources files can be exported from terminal.sexy. The iTerm2-Color-Schemes repo also has many example color scheme files in xrdb and Xresources format.

Demos and Examples

The GodotXterm repository contains several example scenes in the /examples directory. After cloning this repo you will need to either build the GDNative binaries from source or copy pre-compiled binaries into your project. See the Setup section for more details.

Other examples of GodotXterm usage are available online:

• Live Demo: An HTML5 export of the GodotXterm repo's example scenes.

• The Guest: A Linux only submission to the Linux Game Jam 2022. Uses GodotXterm in conjunction with the gdtemu addon and Linux's Kernel-based Virtual Machine, to provide the player with interactive VM that can be used in the game world.

• Xterminate: A Linux, macOS, and Windows demo which uses an older version GodotXterm in conjunction with Godot Python.

Supported Godot Versions

GodotXterm aims to support the current stable release of Godot, but may lag slightly. Currently, Godot versions 3.5.x and 3.4.x are supported, but custom export templates are required for HTML5 exports from versions < 3.5. Versions 3.3.x are no longer officially supported but may work if the GDNative libraries are compiled using an older version of godot-cpp.

Installation

GodotXterm is available on the Godot Asset Library. For more ways to install see the Setup section.

Documentation

Documentation is available on GitHub Pages. If you have a question not answered by the docs, or would like more support, feel free to open a new discussion in the discussions section of this project.

Third-party components

The GDNative source code incorporates code snippets and source code from many third-party libraries. The licenses of these components can be found in the various sub-directories of this project (provided git submodules have been cloned). Many of these licenses must be distributed with source and binary distributions of this software. For convenience, the texts of these licenses have been bundled together (but clearly demarcated) in the THIRDPARTY_NOTICES.txt file.

Note: On platforms where the PTY node is not supported or if the library has been compiled with the option disable_pty=yes then only the licenses bundled in THIRDPARTY_NOTICES_nopty.txt are applicable.

Fonts

• The Hack regular font is bundled with GodotXterm as the default Terminal font. This is also the default monospace font of the Godot editor. See the full license.
