Install

Easier way:

$ pip install listconfig

To use the bleeding edge version:

$ git clone https://github.com/puhitaku/listconfig.git
$ cd listconfig
$ pip install -e .

Usage

Specify a .config file in somewhere like Linux Kernel. Formatted list is output from stdout. Redirect it at which you like to put.

$ listconfig /path/to/Kconfig /path/to/.config > out

The ARCH is automatically detected from .config. Specify --arch option to change it manually.

$ listconfig --arch=arm /path/to/Kconfig /path/to/.config > out

The description is generated from the "help" section of Kconfig items. Specify --help-lines or -l to change how many lines to pick.

$ listconfig --help-lines=1 /path/to/Kconfig /path/to/.config
