Ewig Immutable Editor FAQs

Question 1

What is the primary purpose of Ewig-Editor?

Accepted Answer

Ewig-Editor is an educational implementation of a text editor that demonstrates how to use immutable data structures and a single-atom architecture to manage complex application state efficiently.

Question 2

How does Ewig achieve high performance with immutable data?

Accepted Answer

It uses structural sharing via the immer library, allowing new versions of the editor state to be created in O(log n) time without copying the entire data buffer.

Question 3

What is a single-atom architecture?

Accepted Answer

It is a design pattern where the entire application state is stored in one atomic container. All changes are pure transformations that return a new state version, similar to the Redux pattern but implemented in C++.

Question 4

How does this skill relate to CRDT and collaborative editing?

Accepted Answer

The immutable architecture and pure transformations used in Ewig align with CRDT principles like commutativity and causal consistency, making it an ideal foundation for collaborative tools.

Question 5

What C++ libraries are required to explore this pattern?

Accepted Answer

The implementation primarily relies on 'immer' for persistent data structures and 'lager' for the unidirectional data-flow architecture.
