Run rake command rails app:update, it creates a set of new configration files for active storage, action cable, content security policy etc. As we dont use these features, the default ones from code generation are kept.

This project is a tiny compiler for a very simple language consisting of boolean expression.
The language has two constants: 1 for true and 0 for false, and 4 logic gates:
! (not), & (and), | (or), and ^ (xor).
It can also use parentheses to manage priorities.
Here is its grammar in BNF format:
expr ::= "0" | "1"

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.
After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft
That is is basically a "fork" of blog article i'm constantly returning to. It seems that the blog is down:
Dave Bass proposed this which I picked up for my implementation (here for an 8-chars token):
