## What it is
Lisette is a small programming language inspired by Rust that compiles to readable Go, featuring Hindley-Milner type inference, algebraic data types, pattern matching, and Go interop with channels and goroutines. It ships as a compiler CLI with a linter, formatter, 250+ diagnostics, and an LSP for editors like VSCode, Neovim, Zed, and JetBrains.

## Use cases
- write type-safe code that compiles to go
- use rust-like syntax with the go ecosystem
- avoid nil pointer errors at compile time
- pattern matching and enums in a go-targeting language
- gradually adopt a safer language for go backends
- get lsp support for a new language in neovim or vscode

## When to choose
- you want Go's ecosystem and deployment story with stronger compile-time safety
- you like Rust's enums, pattern matching, and immutability but find Rust too complex
- you want readable Go output that interops with existing Go code

## When to avoid
- you need a mature, production-proven language with a large community
- your project depends heavily on Go tooling that assumes Go source
- you need full Go interop today, which is still a work in progress

## Facets
- artifact type: cli-tool
- maturity: active
- function: compiler, programming-language, linter, formatter, type-system
- domain: programming-languages, compilers, developer-tools, backend
- platform: windows, cli, cross-platform
- tags: transpiler, compiles-to-go, rust-inspired, algebraic-data-types, pattern-matching, lsp, go-interop, hindley-milner, linux, macos
