Best way to parse command line arguments in C I recently came across The Fubu. Core Command line parsing implementation I really like it, the reasons being its easy to use although I couldnt find a documentation for it, the Fubu. Core solution also provides a project containing a nice set of Unit Tests that speak more about the functionality than any documentation couldit has a nice object oriented design, no code repetition or other such things that I used to have in my command line parsing appsits declarative you basically write classes for the Commands and sets of parameters and decorate them with attributes to set various options e. Usage Graph, based on these definitions. Below is a simple example on how to use this. To illustrate the usage, Ive written a simple utility that has two commands. First of all, I wrote a Command class for the add command Usageadd, Adds an object to the list. Command. DescriptionAdd object, Name add. Add. Command Fubu. Commandlt Command. Input. public override bool ExecuteCommand. Input input. State. Objects. Addinput add the new object to an in memory collection. This command takes a Command. Input instance as parameter, so I define that next public class Command. Input. Required. Usageadd, DescriptionThe name of the object to add. Object. Name get set. Valid. Usageadd. DescriptionThe value of the object to add. Object. Value get set. DescriptionMultiply the value by 1. Valid. Usageadd. Flag. Aliasnv. Negate. Value. Flag get set. The next command is list, which is implemented as follows Usagelist, List the objects we have so far. Command. DescriptionList objects, Name list. List. Command Fubu. Commandlt Null. Input. ExecuteNull. Input input. State. Objects. For. EachConsole. Write. Line. return false. The list command takes no parameters, so I defined a Null. Input class for this public class Null. Input. All thats left now is to wire this up in the Main method, like this static void Mainstring args.
