+# argument-parser
+
+A lightweight, modern, expressively typed, and highly customizable C++17 argument parser library.
+
+## Features
+
+- **Type-safe Argument Extraction**: Use type traits to automatically parse fundamental types and custom structures (e.g. `std::vector<int>`, `std::regex`, `Point`).
+- **Support for Multiple Parsing Conventions**: Pluggable convention system out of the box, offering GNU-style (`-a`, `--arg`), GNU-equal-style (`--arg=value`), Windows-style (`/arg`), and Windows-equal-style (`/arg:value`).
+- **Automated Help Text Formatting**: Call `parser.display_help(conventions)` to easily generate beautifully formatted usage instructions.
+- **Cross-Platform Native Parsers**: Dedicated parsers that automatically fetch command-line arguments using OS-specific APIs (`windows_parser`, `linux_parser`, `macos_parser`), so you don't need to manually pass `argc` and `argv` on most platforms.
+- **Fluid setup**: Enjoy fluid setup routines with maps and initializer lists.
+
+### Important Note: 
+V1 is deprecated and is mainly kept as a base implementation for the V2. You should use V2 for your projects. If any features are missing compared to V1, please let me know so I can introduce them!
+
+## Requirements
+
+- C++17 or later
+- CMake 3.15 or later
+
+## Quick Start
+
+### 1. Create your Parser and Define Arguments
+
+```cpp
+#include <iostream>
+#include <string>
+#include <regex>
+#include <argparse> // Provides the native parser for your compiling platform
+
+int main() {
+    using namespace argument_parser::v2::flags;
+    
+    // Automatically uses the platform-native parser!
+    // It will fetch arguments directly from OS APIs (e.g., GetCommandLineW on Windows)
+    argument_parser::v2::parser parser;
+
+    // A flag with an action
+    parser.add_argument<std::string>({
+        {ShortArgument, "e"}, 
+        {LongArgument, "echo"}, 
+        {Action, argument_parser::helpers::make_parametered_action<std::string>(
+            [](std::string const &text) { std::cout << text << std::endl; }
+        )}, 
+        {HelpText, "echoes given variable"}
+    });
+
+    // A flag that just stores the value to extract later
+    parser.add_argument<std::regex>({
+        {ShortArgument, "g"},
+        {LongArgument, "grep"},
+        {HelpText, "Grep pattern"}
+    });
+
+    // A required flag 
+    parser.add_argument<std::string>({
+        {LongArgument, "file"},
+        {Required, true},
+        {HelpText, "File to grep"}
+    });
+
+    // Run action callback on complete 
+    parser.on_complete([](argument_parser::base_parser const &p) {
+        auto filename = p.get_optional<std::string>("file");
+        auto pattern = p.get_optional<std::regex>("grep");
+        
+        if (filename && pattern) {
+            std::cout << "Grepping " << filename.value() << " with pattern." << std::endl;
+        }
+    });
+
+    // Register Conventions 
+    const std::initializer_list<argument_parser::conventions::convention const *const> conventions = {
+        &argument_parser::conventions::gnu_argument_convention,
+        &argument_parser::conventions::windows_argument_convention
+    };
+
+    // Execute logic! 
+    parser.handle_arguments(conventions);
+
+    return 0;
+}
+```
+
+### 2. Custom Type Parsing
+
+You can natively parse your custom structs, objects, or arrays by specializing `argument_parser::parsing_traits::parser_trait<T>`.
+
+```cpp
+struct Point {
+    int x, y;
+};
+
+template <> struct argument_parser::parsing_traits::parser_trait<Point> {
+    static Point parse(const std::string &input) {
+        auto comma_pos = input.find(',');
+        int x = std::stoi(input.substr(0, comma_pos));
+        int y = std::stoi(input.substr(comma_pos + 1));
+        return {x, y};
+    }
+};
+
+// Now you can directly use your type:
+// parser.add_argument<Point>({ {LongArgument, "point"} });
+// auto point = parser.get_optional<Point>("point");
+```
+
+## CMake Integration
+
+The library can be installed globally via CMake or incorporated into your project.
+
+```cmake
+add_subdirectory(argument-parser)
+target_link_libraries(your_target PRIVATE argument_parser)
+```
+
+## Building & Installing
+
+```bash
+mkdir build && cd build
+cmake ..
+cmake --build .
+```
