kconfig 实例1: 基于 python 的 kconfig

kconfig 实例1: 基于 python 的 kconfig 系统

安装

pip install kconfiglib

使用

• kconfig.py

  #!/usr/bin/env python
  # -*- coding: UTF-8 -*-
  
  import os, sys
  from kconfiglib import Kconfig
  from menuconfig import menuconfig
  
  def mconf_set_env():
      """
      Set Kconfig Env
      """
      os.environ["MENUCONFIG_STYLE"] = "default selection=fg:white,bg:blue"
      os.environ["KCONFIG_CONFIG"] = os.path.join(".config")
      os.environ["KCONFIG_CONFIG_HEADER"] = "# Generated by My Kconfig Demo"
      os.environ["KCONFIG_AUTOHEADER"] = os.path.join("config.h")
      os.environ["CONFIG_"] = ""
  
  def mconfig(argv):
      mconf_set_env()
      kconf = Kconfig(filename="./config.in")
      menuconfig(kconf)
      kconf.write_autoconf()
  
  if __name__ == "__main__":
      mconfig(sys.argv)
  
  

• config.in

  mainmenu "My Kconfig Demo"
  
  menu "Debug"
  config CONFIG_DEBUG
      bool "Enable debug"
      default n
      help
          Will print debug information if enable.
  
  config CONFIG_DEBUG_UART
      bool "Enable UART debug"
      default n
      depends on CONFIG_DEBUG
  
  endmenu
  

• Makefile

  menuconfig:
      python kconfig.py
  
  

演示

$ ls -a
Makefile config.in  kconfig.py
$ make menuconfig
python kconfig.py
Loaded configuration '.config'
Configuration saved to '.config'
$ ls -a
Makefile config.in  kconfig.py .config config.h

执行 make menuconfig 后多出 .config config.h
