Cinchoo – Command Line Argument Parser, Part 10

Inside Command Line Argument Parser – Parameterized Arguments

Sometimes you may want to pass and assign parameterized dynamic value to command line argument. Cinchoo framework addresses this need.

Let say, you want to pass current date time as command line argument, you can do so as below

N:200 /I -O:C:\Log -D:%NOW%

1. Add a reference to Cinchoo.Core.dll

2. Namespace: Cinchoo.Core.Shell

Cinchoo framework looks into the %NOW% command line argument value, replaces and assigns current date time to corresponding member (Today).

[ChoCommandLineArgObject(ApplicationName = "Hello World", Copyright = "Copyright (c) Cinchoo Inc.")]
public class MyCommandLineArgObject : ChoCommandLineArgObject
{
    [ChoCommandLineArg("D", DefaultValue = "%NOW%", Description = "Business Date.", ShortName = "Today")]
    public DateTime Today
    {
        get;
        set;
    }

    [ChoCommandLineArg("N", DefaultValue = 100, Description = "No of spaces for a TAB.")]
    public int Count
    {
        get;
        set;
    }

    [ChoCommandLineArg("I", DefaultValue = false, FallbackValue = true, Description = "Include Sub directory.")]
    public bool IncludeSubDir
    {
        get;
        set;
    }

    [ChoCommandLineArg("O", IsRequired = true, Description = "Output Directory.")]
    public string OutFolder
    {
        get;
        set;
    }
}

If the application containing above type executed with the below command line arguments

N:200 /I -O:C:\Log -D:%NOW%

When creating instance of MyCommandLineArgObject as below,

MyCommandLineArgObject commandLineArgObject = new MyCommandLineArgObject();
Console.WriteLine(commandLineArgObject.ToString());

And run the application, the commandLineArgObject will contain the below values

Hello World [Version 1.0.0.0]
Copyright (c) Cinchoo Inc.

-- Cinchoo.Core.CommandLineArgs.Test.MyCommandLineArgObject Dump --
Today: 1/6/2012 12:32:00 PM
Count: 200
IncludeSubDir: True
OutFolder: C:\Log

In next section, I’ll list you the possible properties available in Cinchoo framework for use…
