[![Build Status](https://travis-ci.org/lihop/godot-xterm.svg?branch=master)](https://travis-ci.org/lihop/godot-xterm)
Terminal emulator for Godot using GDNative and [libtsm](https://github.com/Aetf/libtsm).
**Note**: If you are looking for the purely gdscript version of this plugin which was based on Xterm.js, it turned out to be too buggy and slow so is no longer being developed or maintained but can still be found in the [gdscript-unmaintaned](https://github.com/lihop/godot-xterm/tree/gdscript-unmaintained) branch.

## Building
### All Operating Systems
You will need at least these dependencies in order to build this plugin:
- Git (for git submodules)
- a C++ compiler (e.g. gcc)
- ar (part of GNU Binutils)
- CMake
- Python
- SCons
### Linux
#### NixOS
You can simply run the [build.sh] script in the `addons/godot_xterm/native` directory:
```
addons/godot_xterm/native/build.sh
```
All dependencies will be pulled in by nix-shell and the build steps will run.
#### Arch Linux and Ubuntu
See the [Arch Linux Dockerfile](dockerfiles/archlinux) and [Ubuntu Dockerfile](dockerfiles/ubuntu) for a list of packages that need to be installed. Once installed, run the [build.sh] script in the `addons/godot_xterm/native` directory:
```
addons/godot_xterm/native/build.sh
```
#### Other Linux Distributions
Will probably be similar to the above. When in doubt check the documentation in the submodule repos, the [build.sh] script, and the [SConstruct] file.
### Other Operating Systems
This plugin is not currently supported for other operating systems (e.g. MacOS, Windows). If you manage to build it on one of these platforms, please submit a PR for this readme.
## Usage
- ### [Terminal](addons/godot_xterm/nodes/terminal/README.md)
The main node provided by this plugin.
- ### [Pseudoterminal](addons/godot_xterm/nodes/pseudoterminal/README.md)
A node that can be used to connect the Terminal to a shell. Currently Linux only.
An example of how to use this node with a Terminal can be found in the [terminal scene](examples/terminal).
- ### TPut
An incomplete helper class based on the [tput](https://invisible-island.net/ncurses/man/tput.1.html) utility.
Example: On the command line you can use `tput cup 5 5` to position the cursor at row 5 col 5.
In GDScript this utility can be used to similar effect by doing:
```gdscript
tput.cup(5, 5)
```
Other commands include `tput setaf` to set a foreground color, `tput setab` to set a background color, and many more.
But only a few of these have been implemented.
Its usage is demonstrated in the script for the [menu scene](examples/menu).
- ### Asciicast (.cast) file importer plugin
[Asciinema](https://asciinema.org) recordings saved with the `.cast` extension will be automatically imported as animations. They can then be added to AnimationPlayer which is a child of a Terminal node. Playing the animation will play the terminal session recording in the parent Terminal.
See the [asciicast scene](examples/asciicast) for an example.
## Examples
There are three example scenes included in this project which you can study to learn more.
- menu.tscn
- terminal.tscn
- asciicast.tscn
