1/9/2024 0 Comments Command to launch spector pro![]() ![]() For this initial example, that’s just the HelloCommand. Then, we configure the app with the supported commands.First, we create an instance of the CommandApp class (line #10).Public override int Execute(CommandContext context, Settings settings)ĪnsiConsole.MarkupLine($"Hello ) Update that file with the following code: Then, right click that folder and select ‘Add > Class’ for the HelloCommand.cs class file. In real-world projects, we will likely have many commands, so let’s start off on the right path by providing a folder for commands. The first code we’re going to write is a command that simply prints a hello message.įirst, create a new ‘Commands’ folder in the project. It parses the command-line arguments passed into the executable and maps those arguments into commands and options (or settings) in our source code. The library makes use of the Command pattern. With the project created, its properties updated, and the Spectre.Console package installed, we’re ready to start coding our first command-line application. There may be some license and verification dialogs, please accept those as well. Select the Spectre.Console from the results list and then click the ‘Install’ button. In the NuGet Package Manager, search for the Spectre.Console package. In the solution explorer, right click on the Dependencies node and select the ‘Manage NuGet Packages’ item.Ħ. Next, we need to add a reference to the Spectre.Console NuGet package (version 0.36.0 or above). NET Core 3.1, so we want to upgrade to the newly released. NET 5.0 (the project template still default to. Default namespace: Cli.Lessons (use the same namespace across our tutorial projects, so that code can be copied between them easily).Assembly name: lesson (to make it easier to use from command line across different lessons, we will set a short name to use for the executable).In the Project Properties window, change the following data and save the file: In the context menu, select the ‘Properties” item. ![]() Update the project properties by right-clicking the project (Cli.Lesson1.1 node) in the solution explorer. This will create a simple project with the default program.cs file… with an empty Main function.ģ. Fig 1 – New Console App Projectįor this lesson, the project name should be Cli.Lesson.1.1 in the ‘tutorials’ folder. Start by creating a new Console App (.NET Core) through the new project dialog. We’re only going through the detailed steps in this lesson and just link back here in future lessons.ġ. The project creation steps in this section will be repeated in numerous lessons, so we should make ourselves familiar with the steps and setup. Repository link: Cli.Lesson1.1 – Repos (). You can either type all of the classes and code in the lessons or get the code from the repository, whichever works better for you. These folder names will match our lesson titles here, so it will be easy to follow along. In the tutorials folder, you will see a project per folder named. You will be able to find all of the code divided per lesson. Source ControlĪll of the sample code in this tutorial series will be hosted in Azure DevOps. In following chapters, I will build a bigger end-to-end sample application that shows the concepts in the context of a larger application. This chapter is going to focus on the basic concepts of the Spectre.Console library to help get started. It also comes with a rich CLI layout/markup library to make our console applications look pretty with color, grids, and tables. They all have their strong points, but I decided to dig into because the project has good support online and ongoing recent development. Cocona makes it easy and fast to build console applications on. It also provides a ton of additional, optional capabilities that you can try such as argument validation, auto generated usage, tab completion, and plenty of extensibility. NET objects that are easy to program against. PowerArgs – converts command line arguments into.Its primary goal is to completely take over the user input layer, letting you forget about the infrastructure and instead focus on writing your application. CliFx – simple to use, yet powerful framework for building command line applications.– an extremely opinionated command line parser targeting .NET Standard 2.0.I started researching some frameworks for building command-line interfaces (CLI) and there are quite a few out there for. There’s always a lot of repeated code to setup the application, parse the command-line arguments, and then map those to operations performed by the program. I’ve been writing a lot of command-line apps to try out. ![]()
