Antelcat.Parameterization: Effortless Command-Line Application Builder

English | 中文

Welcome to Antelcat.Parameterization, a powerful source generator designed to revolutionize the way you create command-line applications. This tool simplifies the process of building CLI applications by automatically generating parsing methods with just attribute marking on classes and methods.

Features

• Attribute-Driven Development: Easily define commands and arguments using attributes.
• Automatic Parsing: Automatically generates methods for parsing command-line arguments.
• Custom Type Converter: Works well with System.ComponentModel.StringConverter.

Demo

The Demo Program implements a simple Docker application to show its features.

1. Pull an Image:

   Command:

   > pull ubuntu
   

   Output:

   Pulling image ubuntu:latest...
   Successfully Pulled image ubuntu:latest
   

   In this example, a custom Image class is seamlessly converted from a string, thanks to the [TypeConverter(typeof(ImageConverter))] attribute applied to Image. Additionally, for locally use, the [Argument(Converter = typeof(ImageConverter))] Image image annotation allows the same seamless conversion.

2. Run a Container:

   Command:

   > run ubuntu
   

   Output:

   ubuntu:latest ubuntu running
   

   This demonstrates how the default value for the name parameter is automatically used when it's not provided in the input.

3. Display Container Statistics:

   Command:

   > ps
   

   Output:

   CONTAINER_ID    IMAGE           NAME    STATUS
   00a57dbe        ubuntu:latest   ubuntu  running
   

4. Stop a Container and Run a New One:

   Commands:

   > stop
   > stop 00a57dbe
   > run --name "my container" --image kali
   

   Output:

   Argument "id" is not specified.
   Stopping container 00a57dbe...
   Pulling image kali:latest...
   Successfully Pulled image kali:latest
   kali:latest my container running
   

   This example highlights the use of named switches, allowing argument reordering. Additionally, it showcases how strings enclosed in "" are correctly parsed.

5. Display Updated Container Statistics:

   Command:

   > ps --all
   

   Output:

   CONTAINER_ID    IMAGE           NAME          STATUS
   00a57dbe        ubuntu:latest   ubuntu        stopped
   0419fcea        kali:latest     my container  running
   

   First, Argument(FullName = "all") replaces the full name of the original showAll. Argument(ShortName = "a") means ps -a also works as same.

   Second, the effect of ArgumentAttribute.DefaultValue is evident. When a switch is used without an accompanying value, the ArgumentAttribute.DefaultValue is automatically converted and used to fill the argument, regardless of the default parameter value of bool showAll = false.

Installation

• Via Nuget (✨Recommanded)

  Uploaded to Nuget. You can install via nuget CLI or your favorite IDE.

• Via source code

  1. Clone or download zip of the source code.

  2. Reference Antelcat.Parameterization and Antelcat.Parameterization.SourceGenerators as follows.

     <ItemGroup>
         <ProjectReference Include="..\Antelcat.Parameterization\Antelcat.Parameterization.csproj"/>
         <ProjectReference Include="..\Antelcat.Parameterization.SourceGenerators\Antelcat.Parameterization.SourceGenerators.csproj" OutputItemType="Analyzer" ReferenceOutputAssembly="false"/>
     </ItemGroup>
     

     NOTICE that OutputItemType="Analyzer" ReferenceOutputAssembly="false" is necessary because it is a Source Generator.

  3. Enjoy.

TODO

• Nuget package.
• Multiple parameters, use T[].
• Automatically generate help documents.
• Check for excess parameters.
• Parameter combination, e.g. -it will both open -i and -t.
