OCamlopts

OCamlopts is a library for parsing command-line options in the OCaml programming language. It allows developers to define and process arguments passed to their programs in a structured and convenient way. The library provides a declarative syntax for specifying the expected options, including their types, short and long names, default values, and help messages.

When a program using OCamlopts is executed, the library automatically parses the command-line arguments provided by the user. It then matches these arguments against the defined options and returns the parsed values. This process includes handling common scenarios such as missing required arguments, invalid argument types, and requests for help (e.g., displaying usage information).

The design of OCamlopts aims for simplicity and expressiveness. Developers can define options using a concise combinator-style interface, making it easy to build complex argument parsers. The library also supports features like positional arguments, mutually exclusive options, and custom argument validation. OCamlopts is part of the official OCaml distribution, ensuring good integration with the OCaml ecosystem and toolchain. Its use simplifies the development of command-line tools by abstracting away the complexities of manual argument parsing.
