**This parser is not actively maintained** since it has been replaced by [Kconfig](https://www.kernel.org/doc/html/next/kbuild/kconfig-language.html). This library has been tested from linux kernel [1.0](https://cdn.kernel.org/pub/linux/kernel/v1.0/) to [2.5.44](https://cdn.kernel.org/pub/linux/kernel/v2.5/) (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

```bash

cargo add nom-config-in

``````

```rust

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> {

    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(())

}

```
