Lamdu is a next-generation live programming environment combining a projectional/structure editor with its own programming language, offering syntax-error-free editing, automatic formatting, rich static typing with inference, and live evaluation annotations. It is a technology preview written in Haskell and not yet recommended for production use.

Use cases

  • try a structure editor instead of text-based coding
  • experiment with live programming environments
  • write code without syntax errors using a projectional editor
  • explore a statically typed functional language with instant evaluation feedback
  • code in a language where identifiers are a display preference (internationalization)
  • research alternatives to text-file-based programming languages

When to choose

  • you want to explore or contribute to experimental live programming and structure editing research
  • you want syntax-error-free editing with continuous evaluation of subexpressions
  • you need a programming environment with built-in internationalization of code display

When to avoid

  • you need a production-ready language or IDE for real projects
  • you rely on text-based workflows like version control diffs, grep, or standard tooling
  • you need a mature ecosystem with libraries and community support
