INF parser in Rust

This is a Windows INF file parser library. Supports UTF-8 & UTF16-LE formats of INF files.

Features

Parse Windows INF files in both UTF-8 and UTF-16LE formats
Support for section-based parsing
Handle key-value pairs and standalone values
Support for quoted values and line continuations
Comprehensive error handling
UTF-16LE BOM detection and handling
Debug logging for detailed parsing information

Usage

Add this to your Cargo.toml:

[dependencies]
inf-rs = "0.1.0"
log = "0.4.20"
env_logger = "0.10.1"  # Optional, for logging configuration

Basic usage example:

use inf_rs::WinInfFile;
use std::path::PathBuf;
use env_logger::Env;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Initialize the logger (optional)
    env_logger::Builder::from_env(Env::default().default_filter_or("debug")).init();
    
    let mut inf_file = WinInfFile::default();
    inf_file.parse(PathBuf::from("path/to/file.inf"))?;
    
    // Access sections
    for (section_name, section) in inf_file.sections.iter() {
        println!("Section: {}", section_name);
        for entry in &section.entries {
            match entry {
                InfEntry::KeyValue(key, value) => {
                    println!("  {} = {:?}", key, value);
                }
                InfEntry::OnlyValue(value) => {
                    println!("  {:?}", value);
                }
            }
        }
    }
    
    Ok(())
}

Logging

The library uses the log crate for debug logging. To see debug messages, you can:

Use env_logger as shown in the example above
Set the RUST_LOG environment variable to debug or trace
Or configure your own logger implementation

About UTF16-LE

INF files are UTF16-LE (unicode 16 Little Endian) format. Ref https://learn.microsoft.com/en-us/windows-hardware/drivers/display/general-unicode-requirement
How UTF-16 LE works
- Each Unicode code point is encoded using either one or two 16-bit code units
- Code points less than 216 are encoded with a single 16-bit code unit
- Code points greater than or equal to 216 are encoded using two 16-bit code units
- The two 16-bit code units for code points greater than or equal to 216 are called a surrogate pair
