Kconfig for Marlin

[classicrocker883]

Description

Use KConfig for configurations

sudo apt install kconfig-frontends
-or use pip-
pip install kconfiglib

If you’re using Windows and Python 3.13 or earlier,
make sure windows-curses supports it.
Install with:
python3 -m pip install windows-curses

#27917

Usage:

• make genkconfig to generate Kconfig/Kconfig_adv
• To create the .config file and load Kconfig UI
• • make menukconfig for Configuration.h
• • make menukconfigadv for Configuration_adv.h
• make writekconfig to generate Configuration.h/Configuration_adv.h for building firmware

Preliminary tests working

Needs work with additional #defines from config files.

so far it works, except gives this warning

Kconfig_adv:11986:warning: multi-line strings not supported
Kconfig_adv:11996:warning: multi-line strings not supported
Kconfig_adv:12027:warning: multi-line strings not supported
Kconfig_adv:12069:warning: multi-line strings not supported
Kconfig_adv:12237:warning: multi-line strings not supported
Kconfig_adv:12247:warning: multi-line strings not supported

One main issue is when generating Kconfig_adv. This should take into account when things are enabled/disabled in Configuration.h, however some things are defined in Marlin/src/inc/Conditionals-6-type.h / MarlinConfig.h / MarlinConfigPre.h ect.

If we could find a way to incorporate things for example: such as HAS_MEDIA, which in Configuration_adv.h - #define SD_PROCEDURE_DEPTH 1 (and others) is in the same #if HAS_MEDIA block and enabled by, however, it is defined in Conditionals-1-LCD.h as so:

#if ENABLED(SDSUPPORT)
  #define HAS_MEDIA 1
#endif

So, basically, using the same code for Configuration.h it thinks things under that #if block are enabled|disabled (if it has #define | //#define) when it should "depend on" #if ENABLED(SDSUPPORT) / #define HAS_MEDIA 1

but there is no real way of knowing.

for anyone that is confused, like say if everything was combined into one Kconfig file. sure it might work fine for some things, but still wont for whatever is defined in other files.

I suppose we could arbitrarily set each one, and find a way for Kconfig_adv/Configuration_adv.h to link to Kconfig/Configuration.h, or make the code work flawlessly, or just redefine everything, or put those specifically defined in Configuration.h which lead into Configuration_adv.h as I was saying earlier and put those into another file.

You can study how I did it in https://github.com/MarlinFirmware/AutoBuildMarlin/blob/master/abm/js/schema.js … which is used to load and parse the data by https://github.com/MarlinFirmware/AutoBuildMarlin/blob/master/abm/editor.js

well I suppose for now what I was able to do was make it work for Configuration_adv.h (make menukconfigadv) except I am currently having trouble getting options which happen to be disabled to stay as an option to choose from.
for instance:
from Configuration_adv.h

#if TEMP_SENSOR_0 == 1000
  #define HOTEND0_PULLUP_RESISTOR_OHMS    4700 // Pullup resistor
  #define HOTEND0_RESISTANCE_25C_OHMS   100000 // Resistance at 25C
  #define HOTEND0_BETA                    3950 // Beta value
  #define HOTEND0_SH_C_COEFF                 0 // Steinhart-Hart C coefficient
#endif

if TEMP_SENSOR_0 != 1000, these HOTEND0_ #define's get completely omitted from the Kconfig menu as an option (instead of being able to choose from) and set to disabled.
