EO Programming Language, Its Objects, and 𝜑-Calculus
README.md

License Zerocracy vitals Stars Telegram

Here are the components around the EO programming language and the 𝜑-calculus it's based on:

  • /eo is the canonical transpiler of EO programs to Java (start here!)
  • /lints is a collection of linting rules for EO
  • /eoc is a command line toolkit for compiling and running EO programs
  • /eo-lsp-server is an LSP server for EO
  • /eo-vscode is an EO plugin for VS Code
  • /eo-intellij-plugin is an EO plugin for JetBrains IDEs
  • /home is where we keep EO sources of all "canonical" objects

Our blog with recent news is here: news.eolang.org. Read our academic papers. Read the book about EO.

Our Twitter tag is #eolang. This is what Hacker News thinks about us.

If you want to discuss, join our Slack workspace and Telegram chat.

By the way, here is the list of things we still haven't had time to implement. You can help!
