Orbital Shell is a command shell based inspired by bash and POSIX recommendations, coded in C# NET 5.0
orbitalshell.github.io/Orbital-Shell/
Orbital Shell is a multi-platform (windows, linux, macos, arm) command shell (according to .Net Core supported platforms and APIs compatibilities), inspired by bash and POSIX recommendations.
It provides any usual bash shell feature (even if modernized) and 'user friendly' syntaxes allowing to access (get/set/call) C# objects.
Developed using C# 8 .NET 5.0 - compatible with modules and libraries targeting .NET Core 3.1 and .NET Standard 2.1

About the project
This shell integrates the most usefull shell commands, and is intented to be extended by coding new commands or downloading new commands modules within a repository of modules. Of course it can be entirely customized by using the features integrated to the shell (scripts, functions, commands, aliases, settings, parametrization,...). Having a strong ANSI/VT-100-220-300-500 support, it provides structured and colorized display of data and information (support of ASCII, Unicode and 24 bits colors).

The project team like to meet people and wish to share pleasure of programming and technology enthusiasm, with fun and good spirit
Features
a view of the shell running in Windows Terminal
- Is a 'bash style' POSIX command shell
- The modules that are integrated into the shell provide the most usefull shell commands (ls/dir,rm,mv,cp,find,echo,clear,more,env,set,export,history,alias,...), tests commands, text editor command, and so on... , covering the fields of file system,text files,console output, data management, user input
- modules can contains any item that the shell is intended to handle: commands, hooks, scripts/functions, settings, help, doc, assets, ...
- dedicated repositories are used to get known modules list
- modules are versioned and delivered throught nupkg packets, currently hosted at NuGet
- modules are installed into the binaries of the shell
- modules to be loaded are loaded by the shell kernel on user session startup
- modules can contains any item that the shell is intended to handle: commands, hooks, scripts/functions, settings, help, doc, assets, ...
- The shell command engine implements:
-
A command line reader with:
- usual input keyboard shortcuts
- auto completion
- input feedback (colorization)
- usual input keyboard shortcuts
-
Streams standard input (stdIn), standard output (stdOut), and standard error (StdErr)
-
Streams redirections ( < > )
-
pipelines of commands:
- sequences of commands ( | ) and conditional sequences of commands ( &&, || )
- groups of commands ( .. ; .. )
- background execution ( & )
- commands return a result code and can returns values
- When returning values and when specified, a pipe ( | ) between commands can pass objects instead of streams
- When returning values and when specified, a pipe ( | ) between commands can pass objects instead of streams
- sequences of commands ( | ) and conditional sequences of commands ( &&, || )
-
Cancellation of commands execution Task (Ctrl-Z)
-
Batches of commands (scripts)
- traditional batch of shell commands (.sh,.orbsh)
- C# language scripts (.cssh)
- traditional batch of shell commands (.sh,.orbsh)
-
Variables
- Variables can store any data of any C# object type
- The command line syntax has been extended to support an object notation to indicate accessing an object member or invoking an object method
- Integrates the os shell environment variables (with type String)
- Are getted and setted with $ (in any command arg), set and =
- The command line syntax has been extended to support an object notation to indicate accessing an object member or invoking an object method
- Functions can be defined by a shell script or by a C# compiled source
- Aliases for command names
- Shell environment : the shell initialization feature deploy and setup a shell environment for the current user (profile folder and initialization scripts: .profile,.alias,.history,.orbsh)
- Variables can store any data of any C# object type
-
Extensibility:
- The default command line grammar can be changed to get other syntaxes (zsh, DOS,...) or a new one
- The command line engine can be overriden and extended to enhance the existing features (auto complete inputs,parsing inputs,running commands,...)
- The default command line grammar can be changed to get other syntaxes (zsh, DOS,...) or a new one
-
notice / caveat
The project orbital shell was dependent of the project DotNetConsoleAppToolkit. Now the library DotNetConsoleAppToolkit project repository is ARCHIVED since it has been integrated into the orbital-shell project repository as project OrbitalShell-ConsoleApp, so it is still under development but code has been moved to this repository

Warning: due to the average age of our main contributors, this project might contains vintage architecture,design and code. Nevertheless the source code is intensively based on young devs preferred patterns, C# 8 language usage (intellisense agrees), and it pretends to fit to good practices and architecture guidelines.
