Hello World in Multiple Languages Extravaganza: Powershell

Hello world project extravaganza, the Powershell version.

Synopsis

This repository contains a collection of “Hello World” powershell programs; from the simplest “Hello World” Powershell, in plain text, to a “Hello World” more complex. This is part of a fun and educational project that showcases how to print “Hello World” in different programming languages. The goal is to have a “Hello World” program in every programming language. This project is inspired by the GitHub Hello World project and you can found it in Hello World Extravaganza website.

check out the code

To get started, clone this repository to your local machine:

git clone https://github.com/silviotorre/helloworld.git

Getting Started

To run the “Hello World” program navigate to the project directory and run the program. Follow the instructions below to run the “Hello World” . Some info: PowerShell is born as a task automation and configuration management framework, designed by Jeffrey Snover and released in 2006, and now is also a cross-platform task automation and configuration management framework, consisting of a command-line shell and scripting language. Unlike most shells, which accept and return text, PowerShell is built on top of the .NET Common Language Runtime (CLR), and accepts and returns .NET objects. This fundamental change brings entirely new tools and methods for automation. PowerShell is open-source software released under the MIT license. Note: there are many frameworks and libraries that use Powershell, in this repo we work simply with Powershell.

Enviroment

• If you want to learn more about Powershell you can visit the Powershell website.
• You can check your Powershell version with the command $PSVersionTable.PSVersion in the Powershell console.
• if you need to download Powershell you can visit the Powershell website.
• If you want to use winget to install Powershell you can visit the Winget website.
• If you want to use chocolatey to install Powershell you can visit the Chocolatey website.
• If you want to use scoop to install Powershell you can visit the Scoop website.
• remember to check the Powershell execution policy with the command Get-ExecutionPolicy in the Powershell console.
• and check also environment variables with the command Get-ChildItem Env: in the Powershell console.

Ok, now you are ready to run the “Hello World” program.

• open a command prompt or terminal
• go in the Powershell directory of hello world project.
• you can run the project web page in windows you can run the helloworld.ps1 file with start command (see example below)
• you can run the project web page in linux you can run the helloworld.ps1 file with xdg-open command

alternatively you can:

• Open the helloworld.ps1 file with a double click.

Example

.\helloworld.ps1

An advanced version of Powershell “Hello World” program

Here a more complex Hello World program, with module and function to print “Hello World” in Powershell and ps1 file. Main.ps1 script will import the HelloWorld module and then call the Write-HelloWorld function to print “Hello World” in the console. You can add a different “Hello World” output in the Write-HelloWorld function or, for example, you can add parameters or new function to print “Hello World” in a different way.

• Open a command prompt or terminal.
• Open Main.ps1 file writing in the command prompt or terminal this command.

.\main.ps1

• You should see the output of the Powershell code in the console.
• Inspect all the files for full details on the implementation.
• add something new, for example a new output, or a new feature or pattern implementation and try to run it.
• If extra task are flagged “Done” you can try to run the unit test file Main.tests.ps1 with the command Invoke-Pester in the Powershell console.

tasks

• basic “Hello World” Powershell and ps1 file
• Advanced “Hello World” Powershell and ps1 file
• Add a different “Hello World” output

Extra Credit

• Add external unit test file to the ps1 file
• Add advanced features to this project

Contributing

Feel free to contribute your own “Hello World” programs to this repository. Simply create a new directory with the name of the programming language and add a file named helloworld. with your implementation. Don't forget to update the README file to include your contribution!
