A Config.in parser written in rust.

This parser is not actively maintained since it has been replaced by Kconfig. This library has been tested from linux kernel 1.0 to 2.5.44 (542 versions).

A Config.in file looks like this:

# 2.5.0/arch/i386/config.in
mainmenu_name "Linux Kernel Configuration"

define_bool CONFIG_X86 y
define_bool CONFIG_ISA y
define_bool CONFIG_SBUS n

define_bool CONFIG_UID16 y

mainmenu_option next_comment
comment 'Code maturity level options'
bool 'Prompt for development and/or incomplete code/drivers' CONFIG_EXPERIMENTAL
endmenu

Getting started

cargo add nom-config-in

use nom_config_in::{parse_config_in, ConfigInFile, ConfigInInput};
use std::path::PathBuf;

// curl https://cdn.kernel.org/pub/linux/kernel/v2.5/linux-2.5.0.tar.xz | tar -xJ -C /tmp/
fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config_in_file = ConfigInFile::new(
        PathBuf::from("/tmp/linux/"),
        PathBuf::from("/tmp/linux/arch/i386/config.in"),
    );
    let input = config_in_file.read_to_string().unwrap();
    let config_in = parse_config_in(ConfigInInput::new_extra(&input, config_in_file));
    println!("{:?}", config_in);
    Ok(())
}
