Are there any documentations on how to expose c class as berry class? I'm still confused how to do this. Im trying to expose esp8266 library classes to be used in berry as a class. Thank you for this great library.

The easiest way if it is not performance sensitive is to use https://github.com/berry-lang/berry_mapping

Otherwise you need to do it the hard way.

There are plenty of examples in Tasmota https://github.com/arendst/Tasmota/tree/development/lib/libesp32/berry_tasmota/src

@s-hadinger
I hope to extend the function of tasmota's berry by adding a custom xxx.be in embedded. but encountered a problem
I can't generate solidified_xxx_xxx.h in solidify.
I tried to compile the berry of this project into bin format, and then put it under /usr/local/bin/
But I can't generate solidified_xxx_xxx.h file with berry -s -g or cat solidify_all.be | berry -s -g.
May I ask how to generate solidified_xxx_xxx.h.
thanks

You just need to compile a local version of Berry. Use make in lib/libesp32/berry. Then change directory to lib/libesp32/berry_tasmota and use ./solidify_all.be

After I execute it, I get an error

error: cannot open file '-s -g'.

@s-hadinger
thanks
I have successfully executed with cat solidify_all.be | ../berry/berry -s -g and obtained the solidifed_xxx.h file
But I found that the four files i2c_axp192.be / i2c_axp202.be / lv_tasmota_widgets.be / lv_tasmota.be cannot be compiled
For the two files of i2c, it is prompted that the I2C_Driver class cannot be found during compilation. I couldn't get both files to compile after i2c_driver.be, had to remove
The two files of lv cannot be compiled. an error message
