Hello, Here's two small Kconfiglib (https://github.com/ulfalizer/kconfiglib) updates. First, I've made it a lot easier to try out the menuconfig implementation on the kernel. This will work now, in the kernel root: $ git clone https://github.com/ulfalizer/Kconfiglib.git $ git am Kconfiglib/makefile.patch $ make kmenuconfig Here's an animation that demonstrates various menuconfig features: https://raw.githubusercontent.com/ulfalizer/Kconfiglib/screenshots/screenshots/menuconfig.gif Secondly, there's now a handy cross-referenced documentation generation script available. Example documentation output (warning: heavy page, lots of symbols): https://docs.zephyrproject.org/latest/reference/kconfig/index.html The script that generates the documentation: https://github.com/zephyrproject-rtos/zephyr/blob/master/doc/scripts/genrest.py The recently added Kconfig preprocessor has been implemented for a while now, along with an extension that allows preprocessor functions to be defined in Python. I've also fixed some broken/incomplete behavior from the C tools, like not being able to add symbols to choices by giving them a name and defining them in multiple locations (though I think projects sometimes overdo multiple definitions :). This is actually just a menuconfig hack that aggregates the menu nodes from all choice definition locations when you enter a choice. Zephyr and several smaller projects now use Kconfiglib exclusively. Feedback appreciated! Cheers, Ulf
