argument-parser

A small command-line argument parser written in C.

This project is mostly for personal use and education. The goal is to build a minimal CLI parser from scratch to better understand how argument parsing, validation, and simple library design work in C.

The name argument-parser is temporary and may change later.

Goal

The main goal is to create a small but usable parser that can:

• create a parser configuration
• register flags
• parse argc and argv
• store parsed flag values
• validate common user input errors
• retrieve values from parsed flags

TODO List

• Create parser config

  • name
  • version
  • description

• Register flags

  • flag name
  • type
  • required/optional

• Parse argc / argv

• Store parsed flag values

• Validate errors #2

  • unknown flag
  • missing value
  • invalid type
  • missing required flag

• Retrieve values #1

• Return error codes

• Print basic error/help message

Planned Features

The first version will stay intentionally small. More advanced CLI features may be added later, such as:

• short flags
• default values
• automatic help output
• positional arguments
• --flag=value syntax
• subcommands
