Command Line Parsing

Question

I need a command line parsing utility. In the brief 10 second that I've spent googling, I found NConsoler. Can anybody recommend anything else?

Answer 1

You can take a look at

and

GetPot command line parser

Answer 2

If you're interested in .NET (your question doesn't give any information) I've had the Plossum.CommandLine library recommended to me before now. I haven't used it myself, but you might want to take a look.

Answer 3

If you are talking about .NET then see the answers to this question.

The BizArk library contains a command-line parser.

Basically you just create a class that inherits from CmdLineObject, add properties that you want populated from the command-line, add a CmdLineArgAttribute to the properties, then call Initialize in your program. It supports ClickOnce URL arguments too!

Features (from the site)...

• Automatic initialization: Class properties are automatically set based on the command-line arguments.
• Default properties: Send in a value without specifying the property name.
• Value conversion: Uses the powerful ConvertEx class also included in BizArk to convert values to the proper type.
• Boolean flags. Flags can be specified by simply using the argument (ex, /b for true and /b- for false) or by adding the value true/false, yes/no, etc.
• Argument arrays. Simply add multiple values after the command-line name to set a property that is defined as an array. Ex, /x 1 2 3 will populate x with the array { 1, 2, 3 } (assuming x is defined as an array of integers).
• Command-line aliases: A property can support multiple command-line aliases for it. For example, Help uses the alias ?.
• Partial name recognition. You don’t need to spell out the full name or alias, just spell enough for the parser to disambiguate the property/alias from the others.
• Supports ClickOnce: Can initialize properties even when they are specified as the query string in a URL for ClickOnce deployed applications. The command-line initialization method will detect if it is running as ClickOnce or not so your code doesn’t need to change when using it.
• Automatically creates /? help: This includes nice formatting that takes into account the width of the console.
• Load/Save command-line arguments to a file: This is especially useful if you have multiple large, complex sets of command-line arguments that you want to run multiple times.
