Full summary

Version 1.0.0 details

Below you can review the complete feature summary.

Overview

Lucia v1 is composed of two complementary products:

  • Lucia Compiler: transforms Lucia code into Python or JavaScript, including semantic analysis and CLI execution.
  • Lucia Editor: an IDE-style editing environment focused on productivity, learning, and day-to-day compiler workflows.

The v1 value proposition combines simplicity, an education-first approach, and an extensible architecture for future growth.
