Introduction

WebTty is a simple command-line tool that's inspired by GoTTY, mostly a learning experience about how terminals work internally. Built with ASP.NET and XTerm.js the tool allows turning any CLI tool into a web application. In short a TeleTYpewriter for the web that runs on any modern browser or platform.

Installation

Dotnet tool

Download .NET Core 3.1 or newer. Once installed, run this command:

dotnet tool install -g webtty

Native

curl -L -o webtty{.exe} https://github.com/nickvdyck/webtty/releases/download/{VERSION}/webtty.{PLATFORM}

You can replace the version portion by one of the releases found on GitHub. The platform can be replaced with a supported dotnet RID, this represents the platform you want the tool to run on. The following ones are supported:

  • osx-x64
  • linux-x64
  • linux-musl-x64 (alpine)
  • win-x64

Ubuntu dependencies

apt update
apt install libicu60 libssl1.0.0

Development

Prerequisites

Setup

Before you can kick off a build you will need to run the following command. This will restore the project's dependencies and generate the required JSON schema messages. (This is necessary because not everything is fully integrated into MSBuild yet.)

Unix (Linux/MacOs)

make setup

Windows

./setup.ps1

This command/script needs to run after any change to the schema.

Dev

You should be able to open the project in your favourite editor and use any integrated build flows from within the editor (eg Visual Studio, VS for Mac, Rider, ...)

If you prefer using the CLI then the following commands will come in handy. These commands are Unix only, on windows you should be able to just use the dotnet cli tool. The Makefile in essence is just a wrapper around the dotnet cli to save you some keystrokes.

Start server and watch for changes

make dev

This will start the webtty host in watch mode. And it will spin up the client with webpack-dev-server, allowing for a quick dev -> validate cycle.

Package

make package # Package as a nuget global tool

make package-native # Publish self-contained binary tool for linux
make package-native RUNTIME=osx-x64 # Publish self-contained binary tool for osx

Installation
