mruby/c application template for ESP32
Before you get started you will need to follow the setup documentation from the esp-idf project for your specific operating system.
I have only tested this on macOS and using the most recent version of esp-idf.
You will need to recursively clone this project with the recursive flag because it includes mruby as a submodule:
git clone --recursive https://github.com/mruby-esp32/mrubyc-esp32.git
The main ruby program can be found in the
main/resource/hello.rb file. The
makefile configuration in
main/component.mk and the main entry point source
main.c will also be of interest if you want to change the name of
the ruby script. The examples included are very simple scripts that only print
to the ESP32's debug console.
You need the mrbc command to generate mruby bytecode from .rb file.
MRUBY_PATH for environment variable.
I'm assuming you have followed all the steps in the install documentation and are at least somewhat familiar with the building steps. With that in mind you can do something like the following and see the example running:
make menuconfig make MRUBY_SCRIPT=hello.rb make MRUBY_SCRIPT=hello.rb flash monitor
MRUBY_SCRIPT can be replaced with your ruby code.

The clean command will clean both the ESP32 build and the mruby/c build:
